Adhesion, adsorption, wetting: How to characterize and control the relevant forces
Adhäsion, Adsorption, Benetzung: Charakterisierung und Kontrolle der relevanten Kräfte
Karin Jacobs
Universität des Saarlandes, Saarbrücken
Prof. Dr. Karin Jacobs studied physics at Constance University, Germany. Passing career stages as
postdoc at the Max-Planck-Institute for Colloid and Interface Research in Berlin/Golm, research assistant at Ulm Universtiy, project leader at Bayer AG in Leverkusen and several stays abroad in Israel
and Australia, she took up a chair in experimental physics at Saarland University in 2002. Since 2014,
she is awarded a Fellow of the Leibniz-Institute for New Materials INM in Sarbrücken. She coordinated a priority program of the German Research Foundation DFG focussing on microfluidics and is
panel and research member of the DFG collaborative research center SFB 1027, which is devoted to
biophysical research topics. In April 2015, she was elected as a member of the Academy of Sciences
and Literature | Mainz. Her research subjects span from functionalized surfaces and tailored wetting
properties to the analysis and control of adhesion and biofilm formation.
Abstract
The physical origin of adhesion, adsorption and wetting phenomena are intermolecular forces
[1]. Their control will enable a tailoring of the respective phenomenon to the desired outcome. Yet,
which forces are the leading ones? What has to be controlled in which system? In this contribution,
pathways to characterize the relevant forces will be shown. Examples will comprise the wetting of
surfaces [2], the adhesion of bacteria [3,4] and the adsorption of proteins [5].

Abstract
In textile re-processing in recent years numerous measures for resource reduction were introduced.
A further reduction is limited because of various reasons. In the frame of two research projects (IGF
17155 N: Development of resources saving and gentle to textiles re-processing procedures based on
shock waves and IGF 17887 N: Reprocessing of sensitive outerwear with radial shock waves), therefore entirely new approaches for the generation of mechanical action in cleaning during the washing
process was attempted by using shock waves.
Focused shock waves currently are mainly used in medical technology for lithotripsy (gall, kidney)
successfully. Focused shock waves have a higher by up to 1000-fold energy input compared to
ultrasonic waves. Their excess pressure proportion is up to 100 MPa which is reached within 100 ns.
When striking the textiles therefrom flow effects are produced on the textile surface. In addition, the
resultant tension forces at the media interfaces and inside of the soil easier removal of soil. Focused
shock wave application requires fabric position in focus area (constant distance generator-fabric);
creates acceptable soil removal with reduced detergent dosage within short treatment duration (60 s)
and low textile damage. They are applicable at low temperature. Problem of focused shock waves is
the low treated fabric area. In spite, they are suitable for treatment of textiles sensitive to temperature
and mechanical agitation.
Currently, the effect of radial shock waves is investigated (IGF 17887 N) for use in reprocessing of
sensitive outerwear. Radial shock waves have the advantage of larger treated surface area and higher mechanical input at low distances between applicator and textile surface. The presentation gives
an overview of the achieved research project results.

Abstract
Technical low-pressure plasmas are already in use in various branches of industry. At the moment, they are mainly used for coating of objects with complex geometries, such as coating or
are employed to etch electric circuits. Technical plasma is an ionized gas, using electricity, heat, or
microwaves to provide the energy required for ionization. Under low-pressure conditions, only low
amounts of gas are required to fill large reactors with plasma, resulting in low running costs, albeit the
vacuum-capable equipment is still expensive. Besides their uses in the technical industries, relatively
recent studies have shifted the research focus to clinical applications. While atmospheric-pressure
plasmas are mainly investigated for the treatment of patients to treat skin infections or cancer,
low-pressure applications are considered as a potential alternative to classical medical sterilization methods such as autoclaving, dry heat, or UV radiation. The main advantages low-pressure
page 7
plasmas have over conventional sterilization methods is their relatively low temperature, ranging at
a maximum of about 70 °C but can also be facilitated below 40 °C and, due to their gaseous nature,
ability to engulf complex 3D samples preventing shadowing effects known to be an issue with UV
lamps. Low-pressure plasma applications can be tuned to inactivate microorganisms on very short
time scales. Typical decontamination experiments require treatment times of significantly less than
10 minutes, including the waiting time for evacuation and venting. Depending on the employed gas
or gas mixture, resulting plasmas consist of a complex mixture of reactive species, UV photons, and
accelerated ions, which can all cause bacterial inactivation, though the inactivation mechanisms are
still under investigation.
A very high-frequency capacitively coupled plasma (VHF-CCP) source has been used to investigate the inactivation efficiency of a cost-effective low-pressure plasma system. Different spores
as well as macromolecules can be investigated with regards to their inactivation rate as well as the
underlying mechanism of action. Bacterial spores are a typical model organism for decontamination
experiments and Bacillus subtilis and B. pumilus spores were compared to assess the tolerance
of different strains to plasma treatment. Furthermore, spore contaminations were introduced into
complex 3D objects to assess the sterilizing properties under realistic conditions. Besides obtaining
inactivation efficiencies, inactivation mechanisms have been investigated using models of biological macro molecules, such as plasmid DNA and proteins. To understand the impact of plasma on a
molecular level, plasma-induced modifications to these biological models have been investigated in
detail.

Abstract
Water is an essential part of the production process for various technical operations. Although the
focus is normally on the bacterial population within the water, the preferred form of life of microorganisms is in biofilms. They all have a common feature: the cells live in close associations at high
densities and are embedded in an organic matrix of biopolymers, the so-called extracellular polymeric substances (EPS, 1) that are produced by the organisms themselves.
Biofilms can cause hygienic and odor problems in washing machines (2,3) or may play a role in medical-related infections. Various types of surfaces in clinical settings are prone to biofilm deve-lopment and may increase the risk of diseases (4). Also in kitchens for commercial food preparation,
page 8
General
Session
biofilm can be a source for food borne illness (5). In industrial production processes, biofilm can
decrease product quality and quantity, cause material damage leading to interruptions of the production process, and preventive overdosing of biocides and cleaners (6).
An important starting point for the removal of unwanted biofilm is the breakup of their mechanical
stability, which develops through the cohesive forces within the EPS-matrix. Even though mechanical cleaning is the most effective method to remove biofilm, it is not always easily done. Under these
circumstances, suitable cleaning agents are used. The applied agents should also constrain the
removed biomass from settling down in other parts of the system and prevent new biofilm formation.
Since 50 years KOLB has treated paper machines successfully in order to prevent biofilm formation
with a combination of biocides and deposit dispersants, which are formulations of surfactants (7).
From our expertise in the different industries we serve, we developed blends to enhance the biofilm
removing and inhibiting properties. In the KOLB designed test method to evaluate the efficiency of
proprietary performance blends we screened several combinations of surfactants. The tests resulted
in a blend which could remove biofilm up to 50% and inhibit biofilm formation up to 80% in comparison to the non-treated control. In first field tests with industrial cooling water we confirmed the biofilm
preventing properties over a period of four weeks. Our new surfactant blend could be beneficial in
final products; like laundry detergents, cleaning concentrates for medical instruments, hard surface
cleaners, and water conditioning chemicals.

Abstract
The Xeros laundry washing system uses specially-designed polymer beads in place of large
amounts of hot water to remove stains from fabrics. These polymer beads efficiently extract stains
from fabrics and, as water is no longer the primary means of removing stains, the Xeros system can
get fabrics clean while using significantly lower temperatures with less water and detergent than a
standard commercial laundry machine. The current design and size of the Xeros beads are a direct
result of years of research by the Xeros R&D team. In testing various bead compositions, sizes, and
designs, it was found that several factors affected the cleaning performance of the beads. Not only
do Xeros beads last for hundreds of uses, they are completely recyclable as well. The polymers used
in the Xeros beads are suitable for several applications, such as the manufacture of plastic parts for
automobiles.

Abstract
New developments in the field of household washing technologies are experimentally evaluated in
order to estimate the impact on detergency. Two questions are answered:
1) What is the magnitude of enhancement of the absolute washing performance?
2) Is the ratio of stain removal between different stain groups changed by the new technologies?
The experimental setup follows a typical household washing scenario, comparing the same washing
program with and without the new technology. Technologies that were considered are water spray
systems, washing with foam and washing with polymer pellets.
In the case of the polymer pellets, standard industrial grades of PA6, PA12 and PET were used. In
order to control the program parameters in this case a transparent laboratory prototype washing
machine was used.
For all technologies the results show no or only minor changes in the ratio of stain removal between
different stain groups. Major changes comparable to the use of different detergent types, i.e. universal powder and liquid detergent, were not observed. Therefore the main influence on stain removal
is still the appropriate choice of the washing program and the use of an efficient detergent. In the
case of the polymer beads no strong absorption of soil could be found. Therefore the main effect
seems to be a small increase in mechanical action. Surprisingly the mechanical action could not be
measured by standard test sets for mechanical action.

Abstract
Currently, consumers are using 40ºC, 30ºC or even lower temperatures for doing their laundry. There
is also an increasing trend towards the utilization of short wash cycles and a growing use of liquid
detergents without bleach systems. The current washing conditions have a positive environmental
impact (less water and energy consumption) but causes a negative influence on the laundry hygiene
and can also lead to the formation of bio-films in washing machines, the generation of bad odors
and focus of microbial re-contamination that can be transferred to clothes. The survival and distribution of micro-flora during laundering at 30º or 40 º C has been studied with different strains and a
significant survival and transfer between textiles were found using non bleaching detergents (1). As
a consequence, nowadays, the market is demanding products with the ability to eliminate microbial contamination in textiles. The objective of this talk is to give a general view of strategies and
future trends for reducing microbiological risk in laundy. For achieving this goal, a multidisciplinary
approach is needed. From one side, the design of novel detergents able to avoid microbial concerns
even when washing at low temperature is being researching. In this sense, new natural antimicrobial
extracts able to be formulated in liquid detergents seems a promising approach for enhancing sanitizing properties of laundry products. On the other hand, other strategies for improving microbiological safety of washing machines should be combined. For example, some antimicrobial technologies
could be implemented in the washing machine or the inclusion of antimicrobial materials in the
washing machine could contribute to avoid cross-contamination between textiles and from the environment by inhibiting the formation of biofilms in the machines. In this context, cooperation between
detergency and washing machine sectors is encouraged.

Abstract
In order to save energy, programmes in domestic washing machines nowadays exhibit a tendency
towards longer durations, while lowering down the temperatures used.
While the compensation of the reduction of one washing parameter by enhancing another one has
been known for long and is supported by the concept of the Sinner circle, it stayed unclear, whether
this procedure might also be applied for the microbiological efficacy of a washing process.
Although new studies show that lower washing temperatures can be compensated by longer washing times from a microbiological point of view as well in general, there are some exceptions that have
to be considered.

Abstract
Malodour due to biofilm formation in household devices like washing machines is a recent problem.
Low temperature washing cycles, decreased water consumption and the extended use of liquid
detergents have worsened the hygienic situation in a washing machine.
Swissatest has developed a new method to assess biofilm removal in-situ in a washing machine.
This test method is close to the real situation and complements the former developed lab-scale
screening test.
A comparison of the lab-scale system with the in situ test in the washing machine is presented.
Additionally, further test possibilities are shown to assess biofilm removal of products or treatments
in general and in particular for applications in washing machines.
Pros and cons of hygiene claims in household laundry
Pro und Contra von Hygiene-Claims bei der Haushaltswäsche
Helmut Mucha, Anja Gerhardts, Dirk Höfer
From 1977 to 1983, Dr. Helmut Mucha studied biology with focus on microbiology and biotechnology
at the University of Hohenheim. Afterwards, he completed a study work on the biosynthesis of methane and received his PhD 1987 at the Fraunhofer Institute for Interfacial Engineering and Biotechnology, followed by research on bio- and membrane technology at the University of Stuttgart and in the
industry. Then he founded a department for hygiene and microbiology at the TÜV Südwest under
the aegis of Prof. Walter Steuer, president of the Stuttgart Health Autority. In 1995, Dr. Mucha was
co-founder of the hygiene institute at the Hohenstein Institutes, where he is actually active in R&D.
Abstract
The trend to save energy and resources has positive as well as negative consequences for household laundry. Low temperatures below 40°C, water saving, reduced process time and laundry processes without activated oxygen bleach decrease the microbial reduction and increase the biofilm
problem. But these problems can be addressed. A hygienically correct maintenance of the machine
right from the start diminishes the biofilm and smell formation. The application of biocidal additives
and supplements might improve hygiene in the machine as well as on the textile. The consumer
demand for hygiene programs is increasing with special regard to outbreaks of new epidemics, e.g.
MERS, or old familiar diseases like influenza. Furthermore, the incidence of infectious diarrhea is
continuously increasing. Besides Noro- and Coronavirus, new pathogens are discovered every year.
Small children and immunosuppressed people are mainly affected, but the most increasing risk
group involves the elderly.
This development also concerns the retirement and nursing homes where underwear is often reprocessed using household laundry processes. At least this corresponds to the situation in Germany.
Actually, some additives are available which have a potential to improve the hygienic efficiency of
color detergents and other soft washing processes, but the performance of these additives is quite
different. There are even hygiene programs for household machines and for the reprocessing of
textiles with higher hygienic requirements - but this is not state of the art. As a task for R&D, new additives, programs and washing processes should be tested with hygienic and microbiological methods
on performance and reliability. Modified quantitative suspension tests, phase 2, step 1 and 2 as well

as a customized range of test strains and biomonitors are suitable tools for screening and washing

Kathrin Graulich, Deputy Head of the Sustainable Products & Material Flows and Senior Researcher,
has been working since 1999 at Oeko-Institut. Main areas of her research are sustainable production and consumption, policy concepts and tools and implementation of the European Framework
Directive on Ecodesign of Energy-related Products as well as the European Ecolabel Directive. She
has participated in as well as coordinated several projects related to Ecodesign preparatory studies:
Lot 4 (Imaging equipment), Lot 5 (Televisions), Lot 24 (Professional washing machines, dryers and
dishwashers) and stakeholder representation (Lot C) within the Ecodesign Directive. Recently, she
has been project manager for the Revision of the EU Ecolabel for Comput-ers and Televisions commissioned by JRC Seville.
Abstract
The Ecodesign and the Energy Label directives are two of the policy instruments deployed in the
EU for reducing the environmental impacts of products throughout their entire life cycles. In the last
years, the Eu-ropean Commission’s Directorates for Energy and for Enterprise & Industry have implemented ecodesign and labelling regulations to a wide basket of products.
In the light of technological progress, the Ecodesign and Energy Label Regulations 1016/2010 and
1059/2010 on household dishwashers, as well as Regulations 1015/2010 and 1061/2010 on household wash-ing machines are currently under review. The revision work is carried out for the European
Commission’s Directorate General for the Environment by the Institute for Prospective Technological
Studies of the Euro-pean Commission´s Joint Research Centre (JRC-IPTS) with the technical support
of Oeko Institut and Uni-versity of Bonn.
A comprehensive analysis of household dishwashers and washing machines will be conducted following the Methodology for the Ecodesign of Energy-related Products (MEErP). This will include the
collection, pro-cessing and production of environmental, economic and technical information based
on extensive literature research as well as continuous consultation of experts and stakeholders.
Past and future energy and water efficiency gains by innovative technologies such as new drying
technolo-gies, hot water inlets, heat pumps, sensors, or high efficiency motors will be taken into
account when pro-posing new energy efficiency labelling classes and ecodesign requirements.
Special focus will be laid on the analysis of today’s real-life consumer behaviour. For both product
categories, the potential of ecodesign requirements on resource efficiency will be analysed. Further,
the integration of washer-dryers, i.e. machines combining functions of washing machines and tumble dryers, within the regulations for house-hold washing machines will be considered. To date, no
ecodesign implementing measures have been pre-scribed for washer-dryers while energy labelling
requirements were developed in the past (Commission Di-rective 96/60/EC).

Abstract
Europe has had an energy label for washing machines since 1996. The label was introduced to
inform consumers at the point of sale about the performance and resource requirements of each
washing machine and thereby drive reductions in energy and water consumption through market
forces. The energy label was refined in 2011 when three extra classes of higher energy efficiency
were introduced and minimum performance requirements were set in the ecodesign regulations. At
the same time, the measurement procedure by which washing machines were assessed for performance was revised to include an additional programme, tests at half load as well as full load, and
measurements in low power modes (when the washing machine is idle). The European Commission
is currently reviewing the energy label again to see what further improvements in energy efficiency
can be made.
This paper investigates the impact of the energy label as it currently exists and provides some indication on the direction future developments should take. Evidence is drawn from published studies on
consumer habits, data declared by the washing machine manufacturers, a limited survey of consumers and the author’s experience of carrying out washing machine performance tests. It shows that
washing machines can qualify for the highest energy efficiency rating (A+++) and comply with all the
requirements of the ecodesign regulations but still fail deliver the expected energy and water savings
for the consumer. Much of the problem is caused by washing machine manufacturers employing
extremely long programmes for the energy label performance test but other problems are also discussed. The paper concludes by offering a strategy for overcoming these problems by revising the
energy label in a way which will help to drive effective improvements in energy efficiency.

Abstract
Verification of the compliance of gadgets under the energy label and ecodesign regulation is
essential to ensure a level playing field on the market and the achievement of the expected savings
in energy and other resources. In Europe this is task of the national market surveillance authorities
(MSA), which will normally ask a competent testing laboratory to do the relevant measurements when
it comes to verify any declared data. But doing those tests is not a simple task and errors may occur,
even if the laboratory is accredited. How can MSAs reduce the risk of issuing false verdicts of wrong
declaration, based on errors in the underlying measurements?
ATLETE (Appliance Testing for Energy Label & Evaluation) is a European funded project which
organized the verification of refrigerators and freezers (ATLETE I) and washing machines (ATLETE
II) on a European wide scale. In case of ATLETE II 50 washing machines taken from the market were
measured and assessed in six qualified laboratories. Additionally five laboratories did take part in
a mini-round robin test for building up additional qualified laboratory capacity. All in all, more than
70 datasets of measurement data on 50 washing machines are available from ATLETE II which is a
unique chance to evaluate the process capability of the individual laboratory as well as the overall
repeatability of the measurement system (together with the product variation) looking for statistical
quality control measures. Knowing these measures testing laboratories and MSAs may have to
tool to check the quality of the measurements done and thus get confidence in the actions they are
supposed to take.
In the presentation the problem is elaborated and a series of solutions are discussed in detail.

Abstract
Over the past 30 years, the energy consumption of washing machines has continued to fall. The
most recent accomplishments in this field have been achieved by extending cycle times in some
cases to over 5 hours - an approach which would previously have been considered inconceivable.
This was often combined with a reduction in wash temperatures to far below the selected value. The
impact on hygiene and the resultant dissatisfaction among consumers has been well documented.
Alongside ECO programmes for label compliance, manufacturers of washing machines also offer
further programmes featuring higher temperatures and shorter cycle times.
Approx. 70% of the energy consumed in a 60°C cottons programme goes into heating the free and
bound wash liquor, the objective being to significantly reduce water levels as a major contribution
towards energy conservation. This has been achieved through the introduction of a wash process
during much of which laundry is for the most part only damp rather than wet.
Compared with conventional systems, this approach necessitated the complete redevelopment
of load sensing systems, the laundry wetting process and heating componentry. Load detection
relies on monitoring mass inertia, uniform wetting using suds circulation interspersed with spinning
(Spin&Spray) and the use of steam as a source of heat.
The reduced volume of water considerably increases detergent concentration levels and, energy
input being equal, results in significantly higher temperatures. Both aspects boost detergency and
substantially improve hygiene performance. According to the principles of Dr. Sinner, these benefits
can be used to offset a reduction in the length of the wash cycle, a reduction in the amount of detergent used and lower energy input and mechanical action.
PowerWash for the first time achieves the following:
- A 50% energy reduction per wash cycle
- Less-than-full loads can be washed just as energy-efficiently as full loads under domestic-type
conditions
- Selected temperatures in the wash cycle are achieved despite greater energy efficiencies
- Considerably enhanced hygiene performance even at lower temperatures
- Significant improvement in cleaning performance
- Drastic reduction in cycle times
PowerWash technology is currently undergoing a staged introduction at Miele.

household science. In 2014, Emir Lasic completed his doctoral studies at the Household Science
Section of the Institute of Agriculture Engineering of the University of Bonn. His studies involve the
research in the field of the use of sustainable washing technologies, as well as its acceptance in the
households.
Abstract
In the past years, numerous researches were conducted to model laundry washing in the automatic
washing machine. The most studies, however, were focused to some aspects of the automatic laundry washing (e.g. spinning cycle) and not on the washing process as whole. In this paper, a model
of a washing machine (so-called virtual washing machine) that is based on the data of 9 different
washing machines (rated capacity between 5 kg and 11 kg) is introduced.
All tests are conducted in accordance with EN60456:2005, with some modifications regarding the
washing temperatures, load size and detergent dosage.
The proposed modeling approach is based on multiple linear regression and is used to calculate
the consumption of the water, energy and detergent in dependence of the rated capacity, washing
temperature, duration of the main wash, load size and washing performance. The resulting virtual
washing machine shows a good predicting power.
Decrease of the family size and increase of the washing machines‘ rated capacities: Is there an
optimal way to meet those challenges
Abnahme der Haushaltsgröße und Erhöhung der Nennbeladungskapazität der Waschmaschinen:
Gibt es einen optimalen Weg diese Herausforderungen zu meistern?
Emir Lasic, Rainer Stamminger
Abstract
Two opposing trends are observed in Europe: increase of the washing machine’s rated capacity and
the decrease of the household size (hence a decrease of amount of laundry that has to be washed).
Taking into consideration those two trends, the question arises: What kind of consumer behavior is
necessary to use the washing machines with a higher rated capacity in a more sustainable manner?
To answer this question, real life washing machines are tested and the data from the tests is used to
develop a model of a washing machine (“virtual washing machine”).
Furthermore, a model that reproduces to some extent the household’s washing behavior (“virtual
washing household”) is also developed.
By conducting parallel simulations of the usage of the “virtual washing machine” by the “virtual
washing household” and by varying device-, household- and behavioral parameters an optimal
parameter combination with the lowest environmental impact can be determined.
page 23
“Virtual washing household” is designed in such a manner that a washing cycle is conducted when
the household has enough laundry collected, so that the capacity of the washing machine can be
used. It also offers a possibility to conduct an “emergency washing cycle” when the time needed for
accumulating enough laundry (to use capacity of the washing machine) exceeds the waiting time
acceptable by the consumer (so-called “maximal laundry waiting time”).
The results show that washing machines with a higher rated capacity can be used by smaller households in a sustainable manner, however certain changes in households’ behavior are necessary.

Abstract
Laundry care is a routine task in German households. The main objectives in laundry care are stain
removal, the gentle care of textiles and reduced resource consumption. Results are highly influenced
by consumer behavior e.g. laundry sorting, composition of laundry loads and selection of detergents, washing programs and temperatures.
General information about textiles, the impact of laundry sorting on washing results and the results
of an online survey of consumer behavior are presented. The primary objective of the study was an
analysis of consumer behavior with a special focus on textile prevalence and washing load composition. The size of the survey sample is 1120, of which 5 % do not sort their laundry at all. For those
who sort, the most important laundry sorting criteria are color and washing temperature. A total of
3616 virtual laundry loads were composed by the consumer, of which 20 % consisted of household
items, 60 % of clothes and 20 % of a combination of household items and clothes.
This study was conducted as part of the research project Household Appliances for Laundry Care,
in which researchers from three universities and an industrial partner are collaborating to improve
resource efficiency, gentleness of care of textiles and stain removal in residential laundry care.

Abstract
To reduce energy consumption of dishwashing programmes, the current approach is to de-crease
water temperatures in the programme steps. Programme running times are prolonged in order to obtain a satisfying cleaning performance. This trend was made possible by ad-vancements in the formulation of automatic dishwashing detergents; e.g., enzymes and bleaching activators facilitate the
removal process of soils even at low water temperatures. The trend to decrease water temperatures
of the cleaning step of dishwashing programmes (low temperature electric household dishwashing)
is progressing. As in laundry care, water temperatures may decrease to 30 °C. The Household and
Appliance Technology Section of the University of Bonn developed a low temperature dishwashing
programme, applying water temperatures of 30 °C in the cleaning step (Super-E) (1). Compared with a
current Eco programme, the Super-E dishwashing programme allows saving 25-28 % electric energy
per dishwashing cycle but leads to a significantly decreased cleaning performances on persistently
soiled dish- and cookware and to a significantly reduced removal of fatty food residues on hydrophobic surfaces [ibid.]. In order to find out if the decline of the cleaning per-formance in low temperature electric household dishwashing can be compensated for by adding chemistry, experimental
assays were conducted, varying the percentages by weight of the bleaching system, the alkalinity,
the chelating agent and the enzyme system of a cur-rent automatic dishwashing detergent formulation. The resulting cleaning performance values were used to quantify factor effects in regression
models and arithmetic mean values; the calculated regression models were used to adjust a current
detergent formulation to the re-quirements of low temperature electric household dishwashing. The
results and findings of this study are presented.

Abstract
The most important criteria of automatic dishwashing detergents in consumer test magazines are
cleaning, filming, rinsing and drying of cutlery and table ware. Today there are many kinds of products on the market on a high performance level fulfilling all those needs of the end-consumer. But
these products are based on phosphate which is expected to be limited in 2017 by the EU legislation.
Phosphate replacement at the same cost level of the formulation will lead to a dramatic loss of
cleaning and filming behavior of the dishwashing detergents resulting in many compromises the
consumer and therefore the retailer might not accept. Automatic dishwashing products based on
phosphate alternatives are already in the market today and the consumer is willing to pay a price
premium for these products if they do not compromise on performance.
Trilon® M, a strong and efficient chelating agent offers properties to overcome this performance gap
when replacing phosphates. Trilon® M secures todays established performance levels and supports
a sustainable positioning for premium products.
Automatic Dishwashing without phosphates - without compromise!
It´s your choice!

Abstract
Geschirrspülmaschinen mit Tanks stellen ein sehr komplexes System dar.
Sie arbeiten im Gegenstromprinzip. Das Spülgut durchläuft zunächst eine Vorspülzone,
dann einen oder mehrere Reinigungszonen und wird abschließend klargespült und getrocknet.
Die Wasserführung ist entgegengesetzt. Das Frischwasser der Nachspülung dient der
Auffrischung der Reinigungslösung in den Tanks und des Vorspülwassers.
Um sicherzustellen, müssen die technischen Voraussetzungen laufend überwacht werden,
u.a. die Temperaturen, die Wassererneuerung und die Konzentration der Reinigerlösung.
Die hygienischen Anforderungen beziehen sich auf die Sauberkeit des Spülgutes, die Begrenzung
des Gehaltes an Mikroorganismen und die Trocknung. Die Art der Speisen und die Antrocknung,
das Material des Spülgutes und die mikrobiologischen Anforderungen sind zu berücksichtigen. Die
Sauberkeit der Düsen und die „richtige“ Lagerung der Spülgutteile
ist Voraussetzung.

Abstract
The requirements for hygiene in the food sector arise from the EU regulation on the hygiene of foodstuffs i.e. (EC) 852-854/2004, which require a hygiene management system based on the HACCP
concept (Hazard Analysis Critical Control Point) for canteen kitchens and and many other areas.
Dishwasher processes are recognized as important Critical Control Points within these hygiene management concepts and must be controlled periodically, for which the operator has to take care. However, end product and in-process controls described in respective standards (e.g. DIN SPEC 10534)
exhibit major disadvantages. These disadvantages result from the use of conventional microbiological culture methods providing results only after several days. This testing is expensive and requires a
microbiologist and a lab. A simple and quick method for routine control is not available.
In the course of the presented wfk-project a new rapid assay system for the process control of
dishwasher processes was developed, wherein the specific activity of enzymes is displayed by dye
systems. Since germicidal processes are based predominantly on protein denaturing effects, germ
killing can be represented by the denaturation of enzymes. Therefore, parameters involved in germ
killing (temperature, alkalinity and disinfection component), which are acting on the complex system
of microorganism cells (such as the standard test organism Enterococcus faecium), are correlated
with the decrease of enzyme activity. Enzymes are particularly suitable as surrogate models because
they are biomolecules and underlie denaturing effects in a similar manner as microorganisms.
Functional samples of the developed enzymatic process challenge devices demonstrated a good

practice. Within about 10 minutes such a system allows the evaluation of disinfection performance
of dishwashing processes by visual analysis of colored reaction products released from chromogenic substrates. The rapid test is inexpensive and does neither require skilled microbiologists nor
a laboratory. The hygienic safety in dishware disinfection will be increased by using this rapid test
system, which enables frequent routine checks for in-process control.

Abstract
Hygiene-Monitoring spielt aus Sicht eines Lebensmittelunternehmers eine wichtige Rolle. Das
HACCP-Konzept, verankert in der Verordnung (EG) Nr. 852/2004, fordert in seinen Grundsätzen
Überwachungsverfahren zur Einhaltung, Korrektur und Verifizierung der festgelegten Hygieneparameter. Diese Anforderungen beziehen sich ebenfalls auf die Reinigungs- und Desinfektionsprozesse in z. B. Großküchen und bei der Lebensmittelherstellung. Für Spülmaschinen wäre dies mit einer
Überwachung der für die Desinfektion relevanten Temperatur, Kontaktzeit, Wirkstoffkonzentration
und Waschmechanik erfüllt. Im komplexen Prozess des gewerblichen Geschirrspülens werden diese
Parameter üblicherweise nicht im Sinne des Sinnerschen Kreises voneinander abhängig geregelt,
wodurch die sichere Desinfektion der Spülgüter nicht gewährleistet ist.
MEIKO definiert die Hygienesicherheit bei gewerblicher Geschirrspültechnik neu. Eine intelligente
Lösung lässt die Maschine nach dem zuverlässigen Verfahren der Wärmeäquivalente unter Zugrundelegung der Verhältnismäßigkeit des Sinnerschen Kreises hygienesicher arbeiten. Dabei werden

Neuer Untersuchungsansatz zur Benetzung von textilen Materialien
Prof. Hans Bettermann studied chemistry and mathematics in Cologne and Düsseldorf. His
doctoral thesis and his thesis of Habilitation in the field of Physical Chemistry were concerned
with laser-spectroscopic investigations of optically forbidden transitions in organic molecules as
well as structure determinations of electronically excited states. Since 2001 he is Professor at the
Heinrich-Heine-University of Düsseldorf. His current research interests are the developing of Raman
microscopic tools and their application to thin films and surface structures.
Abstract
The wettability of surfaces is a leading property in many technical processes like painting or
printing. Wetting can be usually pursued by several experimental setups as for instance measuring
dynamic surface tension or contact angles. The wetting of textiles can easily be characterized by the
Draves-Clarkson test which was elaborated by DIN EN 1772. This contribution presents a modification of this setup in which fabrics are attached to a below-weighing balance and then are dived into
pure water or solutions of surfactants. In compliance with the procedure of DIN EN 1772 unbleached
cotton fabrics were used as samples. The balance records the change of buoyancy as well the
change of mass of the tissue as a function of time. The change in buoyancy occurs by the removal
of air bubbles. Each bubble causes a step in the mass-time correlation. For evaluating the wetting
process the mass-time step function was transformed into a logarithmic growth spline function. Their
shapes depend on the selected surfactant and its chosen concentration. Each measurement provides quantitative information concerning the amount of absorbed water, the wetting time and the
affinity of surfactants to the fabric. Changing the type of tissue additionally, the proposed method
enables a complete screening of the conditions of wettability. With regard to this concept it is also
thought to investigate how different types of woven, non-woven or knitted textiles uptake water.

Abstract
Patent publications motivated us to investigate physical chemical parameters to determine the cleaning potential of laundry detergents to compare to classical wash experiments. The chosen parameters are surface tension, conductivity, pH value as well as Haze and Transmission. All parameters are
taken from the washing residue as a function of laundry detergent concentration. A washing model
using an ultrasonic bath has been used together with defined dirt-flags from wfk for simulating the
real washing process. The model correlated to the real wash process. An ideal concentration in use
could easily be identified with the chosen parameters. However, the parameters do not replace real
washing tests in total but catalyze the development process significanty.

Abstract
The limited availability of petrochemical feedstock as raw material for surfactants demands a change
to alternative feedstock which, in principle, is available in abundance. Mother Nature provides a
plethora with respect to renewable and vegetable-based raw materials like carbohydrates or vegetable oils. All of them are excellent starting points for sustainable surfactants. Among those, the
Sophorolipids, a group of biosurfactants with a unique and sophisticated structural composition, are
capable of replacing petro chemically based surfactants.
Sophorolipids are made by a purely biological process using natural yeast with a high carbon uptake.
An effective fermentation process including down-stream processing based on Evonik’s extensive
experience with fermentation processes is going to make Sophorolipids available on an industrial
scale.
Sophorolipids have an excellent toxicological and eco toxicological profile and are completely
biodegradable. Moreover, they are very gentle to human skin. The physicochemical properties of
page 34
Sophorolipids can be tuned either by change in composition or smart formulation.
Sophorolipids exhibit big potential to be used in typical Household Care cleaning applications, such
as Hand Dish Wash liquids, Hard Surface Cleaners or Degreasers. The switch from chemically made
surfactants to Sophorolipids in Household Care formulation is possible without the loss of performance. Even superior application results with Sophorolipids are possible compared to the usage of
non-renewable petro chemically based surfactants.
These factors make Sophorolipids an ideal choice to protect limited resources and switch to materials based on renewable - in principle infinite - feedstock.

Abstract
Soap, a very common cleaning agent, has one important drawback - its insolubility in water containing calcium and magnesium salts, often termed “hard water.” In hard water, insoluble soaps
are formed that tend to flocculate and form what is called “lime soap scum, LSC”, on surfaces e.g.,
shower curtains, bathroom fixtures, bathtubs, shore door, tiling, etc. This oily-looking scum adheres
to surfaces in contact with water, leaving behind the undesirable deposits. LSC can be difficult to
remove if it is left for too long, because it continues to build up each time the area is used. LSC that is
left to build can sometimes combine with mold or mildew and have other discolorations and odors.

Abstract
The driving forces for innovation in Commercial Laundry are mainly: Solutions to save resources and
solutions to extend the lifecycle of rental textiles. Potential ways to reach the latter goal are: Dedicated surfactant solutions, any solution to remove stubborn stains, new bleach systems, anti-greying
agents, new solutions for improved dispersion, washing at lower pH or washing at lower temperature.
More and more polyester fibers or polyester blends are used in the rental textile business. Why do we
see more and more Polyester Blend instead of 100% Cotton? Laundering polyester is more energy
efficient than cotton, polyester is cheaper than cotton, polyester is lighter than cotton, therefore
distribution has a less significant environmental impact, the polyester/cotton blend garment has a
longer lifetime.
To prevent greying of this increasing amount of polyester textiles is a big challenge. On the one hand
there is the trend to use as less water as possible but: any dirt which is removed needs to be held in
the washing liquor. As consequence laundries encounter more greying problems. Greyed polyester is
difficult if not impossible to recover. The industry is looking for new/better solutions.
With Sokalan® HP 20 BASF offers a new opportunity to effectively prevent greying on various types
of fabrics
Sokalan® HP 20 significantly improves the dispersion of particulate soils in the washing liquor. In all
tests a significantly smaller degree of greying was observed also on the ballast load.
and varying molecular weight has been evaluated for their efficacy as dispersant for lime soap using
spontaneous precipitation technique. The polymers tested include: a) anionic i.e., lignosulfonate,
carboxyl methylinulin, poly(acrylic acid), PAA, acrylic acid based copolymers and terpolymers,
b) non-ionic i.e., poly(vinyl pyrrolidone), poly(2-ethyloxazoline). Polymers containing ionic groups
i.e., -COOH, -SO3H exhibit poor performance as lime soap dispersant, LSD. In addition, molecular
weight does not seem to exhibit any significant effect on the performance of PAA as LSD. Testing
of polymers with hydrophobic and bulkier groups show significant improvement in polymer ability
to disperse lime soap scum. The optical microscope was used to study the particle size of the lime
soap formed in the presence and absence of dispersant. It was observed that LSC particles were
significantly reduced in the presence of an effective dispersant. The adherence of LSC formed in the
absence and in the presence of dispersant on ceramic was also investigated. Results reveal that LSC
particles formed in the presence of dispersant are less adherent than those formed in the absence
of dispersant.
Biopolymers and Synthetic Polymers as Clay Dispersants for Laundry Applications
Biopolymere und synthetische Polymere als Dispergiermittel für Wäschereianwendungen

Abstract
In laundry application, detergents may contain any number of ingredients designed to enhance the
laundry process. However, surfactant, builder, antiscalant, and dispersant are typically the four major
ingredients present in detergents. The purpose of the surfactant is to improve the wettability of water,
to emulsify, loosen and remove the soil. In presence of soap-based detergents calcium and magnesium ions form insoluble salts resulting in formation of soap scum, build-up of hydrophobic film on
fiber surfaces, and greying of textile. Builders reduce water hardness by complexing with hardness
ions (Ca2+, Mg2+), and thus prevent their interference with the surfactant action. Antiscalant are used
in detergent formulation to prevent fabric encrustation with mineral scale. The role of dispersing
agent is not only to remove soil from fabric but also to keep soil suspended in the wash and prevent
re-deposition on the fabric.
Recently, there has been an increasing interest in the development and application of biodegradable
additives. Carboxymethyl inulin (CMI) is a chemical derivative produced by carboxymethylation of
inulin, a polysaccharide-based polymer present in chicory plant. The results presented in this paper
are a part of our broader research efforts to understand the impact of various factors i.e., molecular weight (MW), type and amount of co-monomer, ionic charge of functional group, etc., on the
performance of polymeric additives as clay dispersants for laundry application. The additives tested
include: green polymers (i.e., CMI. Lignnosulfonates), and synthetic polymers (i.e., polyacrylic acids of
varying MW, and acrylic acid based co-polymers made with different co-monomers. The influence
of various surfactants alone and in combination with polymeric additives as clay dispersants was
also evaluated.

Abstract
Cleaners and detergents are based on a combination of different components, such as surfactants,
sequestring agents, salts and other additives targeting the best possible cleaning of soiled surfaces
at lowest possible cost/performance ratio. Since the start of the development of a large number of
synthetic surfactants, their combinations have been widely used to optimize the cleaning efficiency
and the most different concepts have been used to explain and support the achieved efficiency
boosting. Environmental and sustainability awareness, frequently supported by regulatory and environmentally driven customer pressure (e.g. biodegradability legislation, ecologically sound labeling,
raw materials from natural and sustainable origin) frequently shifted the development and use of
new “optimized effect blends of surfactants” in cleaning formulations during the last two decades.
Where are we today? Which are the targets for tomorrow’s cleaning agents? Which concept for “optimized effect blends of surfactants” is matching best the requirements of an increasingly globalized
market place?
The concept of “optimized effect blends of surfactants” and examples of such systems are explained in different applications, both in domestic as well as I&I applications.

Surface care beyond cleaning
Neue Aspekte bei der Reinigung harter Oberflächen
Gerhard Merkle, Corinna Böhme, Ditmar Kischkel
Gerhard Merkle studied chemistry and graduated in polymer science at the University of Freiburg/
Germany. Subsequently he worked for several years in polymer research at the University of Waterloo, Ontario/Canada and at the “National Institute of Standards and Technology” (NIST) in Maryland/
USA within a project granted by the Humboldt foundation. He prepared fluorescence labelled polymers and investigated polymer blends by neutron scattering. He then joined the Engineering Plastics
Division of the former Hüls AG in Germany. Since 1998 has worked in the area of detergents and
cleaners in various technical and commercial functions at Ciba. After the integration into BASF he
has become responsible for the Application Technology Home Care and I&I. Within this responsibility
he and his international team are investigating the interaction of detergent ingredients to find possibilities for enhanced consumer product performance in the area of detergent and cleaners.
Abstract
Trends and needs in the home care cleaner market are based on convenience, safety, performance
and sustainable cleaning.
For hard surface cleaners high performance cleaning is a key criteria. Two quite different types of
nonionic surfactants have been used in this investigation. Petrochemical derived alcohol ethoxylates
based on branched C10 alcohol, commercially available from BASF within the Lutensol XP® product
range, show excellent primary cleaning properties even on oily dirt. Alkylpolyglucosides, derived
from an oleochemical C8C10 alcohol (Glucopon® product range), can significantly improve foam
stabilization, gloss retention, plastic compatibility and skin protection. These properties ideally fulfill
the needs of a gentle and sustainable hard surface cleaner.
However, premium products even require more claims beyond those cleaning performance aspects:
easy to clean again effect, quick and spotless drying as well as time saving to make household tasks
faster and easier.
The interaction of surfactants with surface modifying polymers enables to provide surface care
beyond cleaning. The combination of these three ingredients - alcohol ethoxylates, alkyl polyglucosides and surface modifying polymers - perfectly contributes to the convenience trends and enables
formulations for many kinds of consumer demands in different hard surface cleaner applications
- whether looking for acidic shower cleaner with anti-rain-effect or alkaline degreaser providing easyto-clean-again performance.

Abstract
In 2009 CENELEC TC 59X started a work regarding the creation of performance standards for professional washing equipment. When Ecodesign Directive 2009/125/EC initiated the Lot 24 studies
the need for performance standards for the types of equipment under study was obvious and a
sub working group (TC59X SWG1.12) was formed in 2010 by CENELEC TC 59X. In 2011 EU Mandate
M495 requested TC 59X to carry of necessary work for new performance standards for professional
laundry equipment.
The task for the SWG1.12 was to create performance standards for professional washing machines
and tumble dryers based on the existing standards EN 60456 and EN 61121. It was identified that essential parts of the standards needed to be rewritten due to the use, size and design of the products
the standard should cover.
The sub working group SWG1:12 now has created two Technical Specifications covering performance
testing of non-household washing machines and tumble dryers. These Technical Specifications will
be modified to European standards when the requirements needed from the EU commission are
known.
During the working period with the Technical Specifications the EU commission withdraw the mandate M495 for legal reasons and is now in a process to define a new mandate covering commercial
laundry equipment. A working paper regarding possible requirements for non-household washing
machines and non-household textile dryers was presented 2013 but also that working paper was
withdrawn after strong critics from stakeholders. A new working paper or draft regulation is expected
later this year.
The presentation will describe the current status of the regulation process and explain the major
differences between the household performance standards and the Technical Specifications for
performance tests of non-household machines.

Abstract
The usage of energy, water and detergents is a major cost factor in the professional laundry.
Therefore, it is must be one of the objectives to reduce these cost as much as possible without any
impacts on the quality.
Anyhow, there is no standard solution towards lower energy and water consumption. The difference
in the technical equipment and the to be washed goods result in different approaches. Working
with a waste water recovery unit may suite one company while others focus on low temperature
detergents.
To identify the optimum solution for a laundry it is important to firstly analyze the actual situation
regarding consumption, used technology and material to be washed. Only by being able to really
assign the energy and water consumption to the different processes it is possible to develop an
optimum scenario. And it is important to measure rather than to rely on the consumption data of
equipment producer.
As an example the implementation of a micro gas turbine into the steam production process will be
used.

Dr. Bernhard Krumme studied Physics at University Duisburg Essen, Germany. He finished his diploma in 2008 in the field of experimental physics. Subsequently, he worked as scientist at University
Duisburg Essen and finished his Ph.D. in 2012. In April 2014 he joined the department of process
technology at wfk. As project manager he is responsible for the development of novel drying technologies for textiles and sensor technology.
Abstract
Tumble dryers show a large energy consumption, which is caused by the large amount of thermal
energy. The specific energy consumption of modern air vented tumble dryers accounts for 0.6 to 0.8
kWh/kg textiles. In the past years, various methods for reduction of energy consumption have been
proposed and were partly realized. The focus of these methods lay on enhanced isolation, control
of the moisture content, heat recovery from exhaust air and controlling the drying program by measuring the textile surface temperature with an IR diode. In order to enhance the energy balance even
further new methods need to be investigated, such as the application of heat pumps.
In the EU project “HP4Drying”, the potential of energy saving by the application of heat pumps shall
be demonstrated for various branches of industry, for this should result in decreased production
costs and, therefore, improve the competitiveness of the companies. The wfk will point out the
possibilities and limitations of the application of heat pumps in industrial tumble dryers regarding
technical and economic aspects as well as the processing.

Abstract
Drying is a complex and energetically intensive process accounting for at least 15% of industrial energy usage and even higher in some specific sectors: 50% in textile manufacturing and up to 70% in
wood industry. In general, most heat losses in industrial dryers are due to the discharge of moist air.
By integrating heat pumps in drying processes energy savings up to 67% have been reported.
The dryer exhaust air serves as the heat source for the evaporator of the heat pump (HP). After
cooling and dehumidification, the working air can (partially) be recirculated and heated up to a higher
temperature level in the condenser. In case of completely closed drying cycles advantages such as
the avoidance of annoying odour or environmental load of contaminants can be exploited. Moreover, other gases than air can be applied in order to avoid the drawbacks of oxygen: explosion risk
or product degradation. Another potential gain is to reuse the condensate as process water, but in
some cases additional costs due to the need of cleaning before discharge could be caused.
During the last few decades a lot of academic research was performed on heat pump dryers (HPDs).
However, reliable industrial applications are still exceptional. Theoretical and experimental analyses
of the HPD system must consider the complex interaction between the drying process and the HP
cycle.
UGent TEI is coordinating the running CORNET HP4Drying project. Six German branch oriented
research partners are collaborating. Main project goals are: to discover new HPD applications by
integrating new HP technologies, to demonstrate potential energy savings by building a strongly automated test rig on which existing, even batch drying processes could be reproduced in original state
and after the integration of a heat pump and to elaborate several industrial case studies showing the
economic and technical feasibility.
For the clarification of the application of heat pumps in laundries the following working steps will be
carried out:
• Determination of branch specific needs for heat pump controlling and application in laundry drying
• Proposal for technical and economic feasibility of heat pump integrated tumble dryers

Andreas Langer was born in 1967. After having finished his general education and working as a mechanic for several years, he completed the study of mechanical engineering at the Higher Education
Institute in Osnabrück and at the Coventry University in Great Britain. After a supplementary study
of economic engineering at the Higher Education Institute in Bielefeld, he was engaged for six years
in plant engineering with a Swiss food production company, before he joined the Herbert Kannegiesser GmbH in Vlotho early 2002. His area of responsibility at Kannegiesser encompasses process
engineering covering the entire range of industrial laundry machinery.
Abstract
The responsible and economic usage of resources becomes more and more the major task of laundry technology. Being supplier for the whole range of laundry technology, Kannegiesser supports
the laundries getting “fit for the future”. Not only for economic but also for social reasons, saving
energy, water and detergents is in many cases demanded and supported by the legislator.
Laundry water is worth much more than the mere fresh water costs. Taking into consideration the
costs for water treatment, the locally varying waste water fees and above all the heat energy in the
wash liquor, laundry waste water must be seen as a valuable resource. And costs are increasing! Depending on the laundry’s size, the reduction of water consumption causes immense cost savings without even considering the detergents included in the recovered and reused wash liquor.
The modern PowerTrans washing technology with its optimizing of the influence factors time, temperature, detergents and mechanics enables lowest consumptions, which still seemed utopic some
years ago. However the saving potential in single processes is limited. We have a look at comprehensive laundry systems to overstep the saving limits of single machines.
The SpecialTankSystem from Kannegiesser provides large storage capacities. Recovered liquor that
can not immediately be used for the washing process because of its color, is stored in large, fully
insulated 2 m³ or 4 m³ tank modules. This liquor can either be used in the batch washer later with
suitable linen or it can be used reasonably for other washing machines.

Abstract
Die Entwicklungstendenzen der letzten Jahre zeigen das nur eine ganzheitliche Herangehensweise
zum Wäschereiprozess die Automatisierung, automatisierte Wäschereilogistik mittels RFID Kennung
und Energieeffizienz umfasst. Nur durch diese ganzheitliche Betrachtung lassen die technologischen Herausforderungen der Zukunft bewerkstelligen und nachhaltige Effizienzverbesserungen
erzielen.
Ein weiterer Schritt besteht darin, ein neuartiges Servicerobotersystem für logistische Prozesse
im Einsatzgebiet industrieller Großwäschereien zu konzipieren, prototypisch umzusetzen sowie in
realen Anwendungsszenarien zu evaluieren. Das Systemkonzept besteht aus steuerungstechnisch
verknüpften, autonom operierenden Kommissionierungs- und Handhabungsmodulen.
Szenario 1 knüpft bei der Entladung der Wäschecontainer von den Anlieferungsfahrzeugen an, nach
der sie in eine vorgegebene Aufnahmezone abgestellt werden. Der Transportroboter (TR) befördert
auf Grundlage der RFID-gestützen automatisierten Wäschereilogistik die über ein Identifizierungsportal (RFID-Gate) erkannten Container entweder ins Zwischenlager oder direkt zur Schmutzwäschesortierung.
In Szenario 2 sollen die durch den TR an dem Vereinzelungs- und Sortierroboter (SR) angelieferten
Wäschecontainer mit Schmutzwäschesäcken automatisiert stationär entladen werden. Öffnen der
Säcke und Vorvereinzeln der Wäscheartikel soll ebenfalls automatisiert erfolgen. Mittels RFID-Identifikation vereinzelt der SR jedes Wäschestück.
Szenario 3 berücksichtigt die saubere Fertigwäsche, die durch den Kommissionierungsroboter
(KR) mit dem Stapelgreifer vom Band abgenommen und in den entsprechenden Wäschecontainer,
bzw. Zwischenlagersystem abgelegt werden sollen. Über ein optisches System wird die optimale
Bestückung der Container ermittelt. Die bestückten Container werden wiederum mittels TR durch ein
Identifizierungsportal ins Lager zur Expedition verbracht. Damit tragen Serviceroboter entscheidend
zur zukünftigen Humanisierung der gesamten Wäscheribranche bei.
Durch das LIN werden der Wäscherei-Branche neue Impulse zur energieeffizienten, automatisierten
Wäscherei gegeben. Die technologischen Schwachstellen im Wäscherei-Prozess :Schmutzwäscheaufbereitung und Kommissionierung der Fertigwäsche wurden mit ersten Lösungen in Angriff
genommen.
Die gegenwärtig laufenden Entwicklungen lassen für die Branche weitere Wasser- und Energiesparende Maschinen und Verfahren erwarten. Hierzu plant das Netzwerk die Optimierung energetischer
Kreisläufe in Wäschereien durch sich selbst lernende und steuernde auf RFID- Technologie und
Robotik basierende Fertigungsmechanismen.

Ralph Ziegler was born in 1968. Graduate in Business Management (BA). He has been working for
many years in B2B sales for technical products in need of an explanation. At the beginning of 2014
he joined EnergieChamp GmbH. Since then he has been in charge of the sales activities and the
contact to industry federations, institutes and manufacturers of drying technology.
Abstract
The talk is about the possibility of reducing costs through recovery and multiple use of heat energy
from the drying process. Cost reduction is an important issue for management in laundries.
Looking at the energy costs is an essential factor.
The company EnergieChamp is a leading specialist in heat recovery on dryers in industrial laundries.
By focusing on this application EnergieChamp offers high savings potentials (30 % to 60 % of energy
costs on the dryer in previous /recent projects) and low-maintenance operation. Under the brand
name TroEnergy® to date over 120 systems have been installed in laundries. The products can be
used independent of dryer manufacturer and independent of age of dryer. Thereby the company
guarantees the previously defined saving potentials in writing. Alternatively the technology can be
used in many cases to boost the drying speed.
In the presentation you will get an overview of the possibilities of heat recovery in laundries as well
as a specific presentation/ description of the application on dryers which are among the biggest
consumers of energy in laundries. Questions of technical requirements, amortisation or maintenance will be answered specifically.
The next generation in low temperature washing

Abstract
Ecolab launched the first low temperature washing for industrial laundries 15 years ago. In 1999 the
first 40°C disinfection program for delicate linen was introduced. This was followed by the first fully
built detergent to disinfect health care linen at 40°C - Eltra 40. Another mile stone was achieved with
the PERformance 40 program in 2011. Nowadays more than 1000 laundries worldwide are using
Ecolab’s low temperature solutions.
Last year an all-new low temperature wash program for hospitality linens was introduced - Oxyguard
40. A new chemistry provides perfect whiteness results, lower energy and water cost, increased
textile life time with the first EU Ecolabel certified process in the industry. These features are real
advantages for laundries servicing hotels with high quality linen.
page 54
Many hotels and public institutions require sustainable services from their suppliers. The first in the
industry EU Ecolabel washing process makes it easy for industrial laundries to meet this requirement - a real competitive advantage.
The presentation will show the features of this new program. The new Ecolab chemistry makes it
again easier for industrial laundries to lower washing temperature to 40°C without compromise in
quality, textile replacement or sustainability.

Abstract
The Industrial & Institutional laundry market is moving towards milder and more sustainable washing
processes. It is no longer unusual to see washing temperatures at 40°C and wash processes are
more and more often designed so less alkali and e.g. chlorine is used, all together making the
process much milder to the textile and thereby improving textile lifetime. At the same time end users
are becoming increasingly concerned about sustainability, ecolabelling and CO2 reduction. These
trends are posing a challenge to the Industry. Washing performance cannot be compromised and
Professional Laundries also have to focus on financial sustainability. In fact, in order to fit sustainability, performance and costs together an important piece needs to be added - this we have found to
be enzymes.
In the presentation we will show how Novozymes multi-enzyme solutions can help close the performance gap which occurs when moving towards milder wash processes, both with respect to the
amount of detergent and the washing temperature used. Several case stories from as well Industrial
as Institutional laundries will prove that not only is it possible to lower temperature and reduce detergent use, it is at the same time also possible to lower the rewash rate.
The benefits are obvious. Lower washing temperatures means energy savings, milder wash conditions and sometimes shorter washing programs. Reduction in rewash resolves capacity constraints
and reduces labor costs. Less alkali and surfactants affords milder washing processes resulting in
increased textile life time, and at the same time a reduction in the COD. Finally, the cases show that

multi-enzyme solutions can improve whiteness even when the use of surfactants and bleach is
reduced. Therefore, using multi-enzyme solutions it is possible to introduce milder and more sustainable washing processes without compromising quality.

Abstract
Bei der Verdichtung von Luft wird der weitaus größte Teil der zugeführten Energie in Wärme
umgewandelt. Die Wärmeenergie wird über luft- oder wassergekühlte Kühler an die Umgebung
angegeben. Durch den Einsatz von standardisierten Plattenwärmetauschern kann der größte Teil
der Wärmeenergie (bis zu 75%) zurückgewonnen werden. Damit wird der Gesamtwirkungsgrad des
Kompressors erhöht, die zurückgewonnene Energie in Form von warmen Wasser (bis zu 80°C) kann
als Prozesswasser oder für die Raumheizung genutzt werden. Das senkt die Lebensdauerkosten
und entlastet die Umwelt.

Abstract
If we talk about the washing process, then, in addition to the appropriate chemistry, mechanics,
temperature and time are important prerequisites. Here’s a substance plays a central role, the water.
During his journey through the washing process, it goes in touch with a wide variety of parts (pipes,
washing machines, water storages ...), it becomes heated and cooled. In the course of its use, the water often changes its physical and chemical properties and interacts with the construction materials
in its environment.
Its corrosive properties can result in equipment damage or damage in the washing process. In
particular, the reduction of the corrosion rate in the steam supply (condensate) can help prevent
damages and to reduce rewashing and maintenance costs.

Automatisierte Herstellung von Textilien mit integrierten elektronischen Komponenten
Interconnection techniques to connect textile substrates and electronical components

Textilforschungsinstitut Thüringen-Vogtland e.V., Greiz
Abstract
Smart Textiles wie zum Beispiel leuchtende Textilien sind heute oft noch Nischenprodukte. Ein
Durchbruch dieser neuen Produkte hängt unter anderem von deren Zuverlässigkeit aber auch von
einer kostengünstigen Produktion ab, die über die Automatisierung der Fertigungsprozesse erreicht
werden kann. Die Entwicklungsaktivitäten des TITV haben sich in den vergangenen Jahren auf diesen Schwerpunkt fokussierten. Im Rahmen des Vortrages werden die aktuellen Entwicklungen des
TITV anhand von Beispielen dargestellt.
Angefangen von der Signalübertragung bis zur Energieversorgung elektronischer Komponenten
stellen leitfähige Garne eine Grundvoraussetzung für den Aufbau smarter Textilien dar. Eine wesentliche Herausforderung bei der Fertigung stellt oft die Verbindung zwischen integrierten Fäden und
externen Elektronikkomponenten sowie Bauteilen, die bereits im Textil integriert sind, dar.
Eine der vom TITV entwickelten Möglichkeiten einer zuverlässigen Montagemethode für elektronische Bauteile auf Textilien ist die FSD Technologie. Die Technologie basiert auf der bekannten Pailettentechnik der Stickerei, die als funktionelle Pailetten (Functional Sequin Devices) durch das TITV
modifiziert wurden und bereits von der imbut GmbH produziert werden. Neben der FSD-Technologie
kann die Bestückung von textilen Leiterplatten durch einen an der Stickmaschine adaptierten Pickand-Place Prozess realisiert werden. Beide Technologien werden ausführlich dargestellt und anhand
der Vor- und Nachteile für verschiedene Anwendungen vergleichend diskutiert.
Eine bereits angesprochene Grundvoraussetzung für die Akzeptanz Smarter Textilien am Markt ist
deren Zuverlässigkeit, die aber auch begleitend zu den Fertigungsprozessen geprüft werden muss.
Entsprechende Normen befinden sich auf europäischer Ebene im Aufbau. Auf die sinnvolle Prüfung
von Gebrauchseigenschaften und am TITV Greiz entwickelte Prüfmethoden wird kurz eingegangen.

Abstract
Bei der Ausrüstung von Textilien werden zunehmend vielfache, aus verschiedenen Anwendungsgebieten geforderte Funktionen bereitgestellt. Einerseits reagiert die textile Herstellungskette in
Abhängigkeit der Marktsituation entsprechend. Andererseits eröffnet dies Möglichkeiten, Textildienstleistungen zu erweitern oder eine optimierte Logistik, insbesondere beim Wäscherei-Kreislauf
zu generieren.
Verdeutlicht wird das an zwei aktuellen Neuerungen, erstens durch die Funktionalisierung von
Textilien anhand eines nahezu unsichtbar in Flachwäsche integrierten UHF-RFID-Transponders zur
Automatisierung des Wäscherei-Kreislaufs sowie, zweitens, am Beispiel des Wiederaufladens von
verloren gegangenen Funktionalitäten bei PSA durch eine Waschbehandlung.
Der Einsatz der RFID-Technologie in Wäschereien zählt zu den vielversprechendsten Ideen zur
Effizienz- und Produktivitätserhöhung: Zur Identifikation ist kein direkter Kontakt mit der Ware
notwendig. Eine große Anzahl kann im Pulk erkannt werden. Vor diesem Hintergrund wurde die Idee
umgesetzt, einen weiterentwickelten RFID-Transponder aus dem UHF-Bereich in Flachwäsche zu
integrieren und anschließend als Identifikationwerkzeug für die Logistik in einem geschlossenen
Wäscherei-Kreislauf einzusetzen. In Abhängigkeit der Saumbreite gelang eine nahezu unsichtbare
und kostengünstige Integration von RFID-Transponder in Flachwäsche-Textilien (Tischdecken, Bettwäsche, Handtücher). Die RFID-Transponder halten der Industriewäsche stand (Temperatur, Druck,
Chemikalien), erfüllen die Anforderungen notwendiger Zertifizierungen und werden verlustfrei im
Wäscherei-Kreislauf identifiziert.
Das zweite Beispiel beschreibt ein Produkt-Service-Konzept, mit dessen Hilfe Funktionalitäten von
PSA (z.B. für Industrie, Hotellerie, Gastronomie), die während des Gebrauchsprozesses und der Pflege verloren gegangen sind, bei der Waschbehandlung wiederaufgeladen werden. Die Agenzien zum
Wiederaufladen der Funktionalitäten werden dem Waschbad dosiert beigemengt. Die Chemikalienkonzentration des Waschbades wird über Variable Optical Path Spectroscopy (VOPS) gemessen.
Die ermittelten Daten werden in einer zentralen Datenbank gespeichert. Nach dem Waschvorgang
erfolgt eine Probeentnahme aus dem Wäsche-Batch und die re-funktionalisierten Bekleidungsteile
werden durch Reflectance Spectrophotometry auf ihr Funktionalitätsniveau geprüft. Die Wirksamkeit
des Kleidungsstücks kann dadurch über den gesamten Lebenszyklus beibehalten werden. Entsprechend bietet das WASH&LOAD-System neben dem Wiederaufladungsprozess die Anbindung an
ein Life Cycle Monitoring Webtool zum Abgleich verwendeter Agenzien und Funktionalisierungsniveaus von Bekleidungsstücken.

Textiles functionalization with microcapsules - fastness to washing
Textil-Funktionalisierung mit Mikrokapseln - Waschechtheit
Tanja Pusic, Tihana Dekanic, Sandra Bischof, Ivo Soljacic
University of Zagreb, Croatia
Abstract
The research is focused on the wellness finishing based on application of microcapsules on the
polyamide pantyhoses aimed for anti-cellullite effect. It is necessary to optimize microcapsules
application, fix them on textiles and prevent their release during the washing. Enhancement of
microcapsules life can be achieved by application of a proper binder and adjustment of external
influences. The qualification and quantification of microcapsules can be done by various methods.
This research is mainly focused on the application of solvent extraction, FTIR and scanning electrone
microscopy (SEM) for identification of microcapsules prior and after the washing.

gutem Schlafkomfort entwickelt, die zusätzlich keimdicht und leasingtauglich sind.
Nach Erstellung eines Anforderungsprofils für Hotels (Schwerpunkt Leasingtauglichkeit und
Komfort) und Gesundheitswesen (Schwerpunkt Hygienesicherheit) erfolgte eine Marktrecherche
im Bereich der Encasings. Diese ergab Preise zwischen 15 und 35 €. Daraus wurden einige Muster
ausgewählt und zusätzlich neue Produkte unter Berücksichtigung unterschiedlicher Membrantypen
und deren Verarbeitung entwickelt. Bei den Materialien kam es primär auf die hautsensorischen
und thermophysiologischen Eigenschaften, die Geräuschentwicklung, die Leasingeignung und die
Keimdichtigkeit an. Neben den bereits etablierten Prüfverfahren kamen auch eigens für das Projekt
entwickelte Prüfmethoden zum Einsatz.
Die im Labor gewonnenen Ergebnisse wurden anschließend im Feldtest verifiziert. Dazu erfolgten
gleichzeitig zwei Feldtests über 6 Wochen im Hotel und Pflegeheim. Die Ergebnisse der mikrobiologischen Untersuchungen zeigten einen deutlichen Einfluss der Encasings auf die Hygienesicherheit.
In beiden Einrichtungen konnte der Keimgehalt gegenüber dem Kissen ohne Encasing um 5 bzw. 6
log-Stufen reduziert werden.
Die parallel durchgeführte Gäste- bzw. Bewohner-Befragung zu den Komforteigenschaften der
Kopfkissen-Encasings ergab größtenteils positive Rückmeldungen: über 80 % der Befragten konnten
bei dem Encasing weder einen Airbag-Effekt noch Raschelgeräusche feststellen. Die Umfrage bestätigte ebenfalls den Wunsch nach mehr Hygienesicherheit durch den Einsatz von Encasings: 92 %
der Befragten empfanden den Einsatz der Encasings als sehr sinnvoll.
Fabric-skin models to assess the transfer of skin infections in realistic scenarios
Textil-Haut Modelle zur Bewertung der Übertragung von Hautinfektionen in realistischen Szenarien

body with particular emphasis on safety aspects, infection prevention and diagnosis and innovative
textiles in health and environmental applications.
Abstract
To consider important measures for infection prevention, direct and indirect transmission routes of
pathogens must be revealed. Therefore, we studied the role of skin and fabrics in the spread of dermal pathogens in order to assess re-infection or infection transfer in realistic scenarios. On the one
hand, we investigated the potential transfer of pyodermas (impetigo contagiosa) between children
in a kindergarten setting. On the other hand, we wanted to know whether head protection/helmets
pose a risk for re-infection with dermatosis or for infection transfer. Therefore, the transmission of
different test strains was studied with standardized fabric-skin models using a technical artificial skin
and fabrics of different fiber types as well as antimicrobial fabrics.
In the setup focussing on impetigo pathogens, friction enhanced bacterial transfer, depending
on fiber type or fabric construction, with polyamide and polyacrylic showing the highest transfer
rates to recipients skin. Nevertheless, notable numbers of bacteria were transferred with all fabrics
investigated in this work, whether made of synthetic fibres or made of cotton. In a fabric-scalp model
focussing on a helmet rental scenario, only few antimicrobially treated fabrics efficiently prevented
the growth of pathogens. Our results show risk factors for the infection transmission of dermatosis
page 62
in the joint use of fabrics. Therefore, fabrics in community facilities or for rental should be washed
and disinfected regularly to prevent pathogen accumulation and spread. Fabric-skin models used
in these studies enable further insight in transmission factors for skin infections on the basis of a
practical approach.

Abstract
Breathing air filtration usually involves the removal of particular and gaseous toxic substances.
Therefore, in respiratory protective devices a combined filtration medium is used. It consists of a
particulate filter and a bulk material like activated carbon or another adsorptive material placed further
downstream.
While the first component is most commonly a nonwoven material for the removal of harmful particles, the second stage removes toxic gases like carbon monoxide or ammonia, either by adsorption
or catalytic deactivation, respectively. Catalyst materials can enhance the filtration performance of
such a device significantly. A widespread commercial application is the use of Hopcalite, a mixed
copper manganese oxide, for the catalytic conversion of carbon monoxide to carbon dioxide.
The catalyst usually consists of pellets with a size of a few millimeters. The conversion rate of the
porous catalyst depends on its inner surface. Smaller particles do not show a higher inner surface
area, but shorter diffusion pathways for the reactants. Therefore, these smaller pellets can enhance
the conversion rate.
This presentation addresses the topic to fix such small catalyst particles on nonwoven materials,
leading to combined filter media for particulate filtration and catalytic deactivation of harmful
airborne substances. Thus, a possibility for a more efficient use of the filter volume is pointed out,
which can help to produce more efficient filter systems. The production process of these systems
could also be simplified. The catalytic active materials are immobilized on textile surfaces by different
methods, which include plasma pretreatment and a new developed infiltration process.

Abstract
Customers of textile service companies demand increasingly work wear, which is functional as well
as individual and fashionable. Such representative work wear is employed increasingly where stubborn and hardly removable contamination (eg. mineral oil, grime or metal oxides) occurs. Currently
many contaminants can only be removed satisfactorily at high temperatures, pH values, detergent
concentrations and strong washing action. Besides high costs, such processes lead to shortened
lifetime of the textiles due to mechanical, thermal and chemical damages. Therefore, the work wear
must be rejected and replaced after a small number of wearing and processing cycles.
One approach to optimize stain removal under mild washing conditions and to reduce costs is the
use of soil-release systems based on pH-switchable polymers. In the ongoing wfk research project
soil-release polymers are used for removal in the alkaline (pH 8-12) environment of washing liquor as
well as application in neutral to acidic (pH 4-7) environment of the finishing liquor. After application,
the pH-switchable polymer forms a sacrificial layer on textile surface. Therefore, the soil release
finishing is soiled during use and not the textile surface itself. The soil release polymer is removed
from textiles along with adherent soil in the next washing procedure to improve the soil removal.
Within the research project renewable pH-switchable soil-release systems based on carboxyl-containing polymers for resource conserving reprocessing procedure were developed. The use of the
pH-switchable polymer improves significantly soil removal, which allows an increased number of
usage and processing cycles of the high-value textiles. Further savings can be realized due to lower
washing temperatures as well as lower chemical demand.

Abstract
High quality work wear such as CI clothing or protective clothing must meet the criteria of textile
protection, sustainability and hygiene. A gentle treatment is needed to preserve the visual appearance or the protective function and can only be realized at low temperatures. The increasing use of CI
clothing in hygienically demanding areas and the current trend of disinfecting washing of protective
clothing lead to new demands for reprocessing: on the one hand an effective and gentle cleaning, bleaching and disinfecting even at low temperatures shall be possible, on the other hand low
resources consumption is required.
A further reduction of resources is currently possible only to a limited extent as the following disadvantages can result:
• Insufficient washing effects and insufficient germ inactivation in the case of strong temperature
reduction,
•
Increased mechanical textile and color abrasion resulting in a shortened lifetime and inadequate
washing effect and
• Insufficient rinsing effect in the case of reduced consumption of rinsing water.
Within an ongoing research project a novel low temperature reprocessing method for hygienically
demanding work wear on the basis of hydrodynamic cavitation is going to be developed by wfk. For
the first time, hydrodynamically cavitated water will be used to increase the mechanical agitation
on the one hand and the bleaching and disinfection of work wear on the other hand. High stability
cavitation bubbles are produced in water. By means of fluid dynamics they are able to be transported
over long distances, such that an entry into the washing machine drum can be realized.

Abstract
For various kinds of textiles the functional requirements specified by European standards for liquid
repellency must be ensured through appropriate controls after each reprocessing by textile service
providers. Examples include protective clothing against liquid chemicals, weather protective clothing
and combined high visibility clothing. Depending on the operating conditions a massive contamination of these textiles by industrial soil, based on mineral oil derivatives with embedded pigments,
can occur. In some cases, soil can be rubbed into the hydrophobic FC- layer by mechanical stress or
friction, resulting in a difficult soil removal.

chemical cleaning methods and process engineering at wfk. His focus is development of new and
innovative cleaning technologies for textiles as well as hard surfaces.
Within the project fluorine-free hydrophobization systems based on silicones are developed. All currently available fluorine-free hydrophobization systems have a much lower hydrophobic effect than
fluorocarbon polymers. The hydrophobic effect can be greatly increased by integrating nanoparticles. Due to the resulting increase in surface roughness the surface becomes superhydrophobic.
Prerequisite for the renewability of the nanoparticles and their binder polymer is the possibility of a
reversible coating on or removal from fiber surfaces in aqueous systems. The application of nanoparticles in combination with fluorine-free binder polymers is carried out in a single-step process
in a slightly acidic immersion bath of an aqueous dispersion (dip application). The adhesion of the
applied nano-systems on the textile surface is caused by both, electrostatic interactions between the
charged groups as well as physical adsorption of uncharged binder polymers on the fiber surface.
Under alkaline conditions repulsive coulomb forces between the charged components of the nano-system and the fiber surface occur due to pH induced changes in the surface charge. Consequently the high performance fluorine-free hydrophobization system is easily renewable.

The presentation firstly shows the typical consumer of energy in a dry cleaning shop. This ranges
from the machines for cleaning, washing, drying and finishing on various assistive devices up to the
building and office technology. The following list of the used energy types and their percentage shall
indicate, where the largest consumers are based and which improvements to be taken make most
sense.
By describing a series of general measures in operation, recommendations are given how to save
energy significantly without investment. Finally, a series of practical examples of running systems
demonstrate concretely their energy saving potential. The cost and amortization consideration for
investments in energy saving systems finally completes the presentation.

Abstract
Today we are living in a very fast changing world with many influences given by governments,
regulations, trends, patents, marketing and technologies. We should not forget the key point of our
business to give the customers good and clean garments, done in an economic and environment
friendly way. For that reason BÖWE thinks every day how to improve this process. BÖWE started long
time ago to improve the energy savings in the dry cleaning industry. The first drying controller was
invented and developed in the sixties from BÖWE. With the 6th generation dry cleaning machines
BÖWE started to set a bench mark with round shaped components for better air flow and automatic
cleaning and maintenance. Furthermore with the cataphoresic coating a new area started in the dry
cleaning machine manufacturing to reduce dirt and lint in the machines. With the automatic water
separator cleaning programs and multi maintenance programs of filters, distillation, water separator,
active carbon units BÖWE made the lives much easier for the dry cleaners. Step by step also small
inventions improved the daily business like special coated button trap basket for an easier cleaning,
but also a much better insulation of the air duct and drum housing saves energy and improves the
working climate in the dry cleaning shops by reducing the temperature approx. 2.5 °C.
With optic devices it is possible today to measure the dirt and the color during the dry cleaning cycle
and to optimize the distillation rate and the energy consumption of dry cleaning machines. If the limit
of the dirt in the solvent is reached the machine pumps the solvent to the distillation, otherwise by
filter back to the tank.
In times where everybody is looking to save money in cutting costs for energy and labor BÖWE
don’t want to cut the quality the drycleaners gives to their customers. Many things have been tried
in the last years to save energy by spraying solvent and not using bath cycles anymore or more and
more using filtration methods instead of distillation process to save energy. For sure we have in the
PTC business so many different garments, textiles, fibers, stains but also industries for example
work wear, gloves, fur degreasing, leathers, textile production, textile care etc. that is some cases the
above methods can work under special circumstances. But in general disadvantages will be caused.
This is the reason BÖWE don’t want to lose the traditional way of dry cleaning in baths to transport
the dirt from the garments out of the machines, but wants to improve that proven technology in an
energy saving way.

Abstract
The presentation gives a short overview about drycleaning solvents in textile care operations. For
many years drycleaning industry worldwide was dominated mainly by perchloroethylene and by
petroleum solvents. Within the years petroleum - white spirit solvents have been replaced in the
different markets by synthetically made isoparaffins. Perchloroethylene and isoparaffin solvents
still have the biggest market share. The ongoing discussions about health and safety issues of
perchloroethylene in Europe as well as in North America inspired the industry to search for more environmental friendly alternatives. Basic requirements for suitable drycleaning solvents are explained
in the presentation. The introduction of cyclosiloxane D5 offered drycleaning industry a gentle and
odourless solvent, this solvent was mainly used in the cosmetic industry - and still is found in many
cosmetics today.
In October 2010 SYSTEMK4 (Dibutoxymethane), an acetal solvent with comparable cleaning performance to perchloroethylene came to the market. To overcome the obstacle of not being covered
from international textile care labelling symbols like defined in ISO 3758, efforts are made to integrate siloxane D5 as well as dibutoxymethane into GINETEX care labelling system.
In the last two years, other alternative solvents like Arcaclean, KTex, Rynex 3E and HiGlo were introduced as drycleaning solvents. Pros and cons of energized drycleaning solvents are discussed in
the presentation.
General trends about drycleaning solvents are highlighted for different markets. The European VOC
regulation and consequences for drycleaning operations are discussed in the presentation. Finally to
give a simple guidance to the operators, basic information about legal requirements for drycleaners
is given.

Behandlung von Textilien kann die potentielle Bedrohung durch pathogene Keime nicht ignoriert
werden. Einfach nur zu Waschen wird den Anforderungen an eine moderne Textilpflege nicht
gerecht. Die Herausforderung liegt darin geeignete Desinfektionsmittel zu finden und gleichzeitig die

Abstract
Within the research project IGF 16070 N a gentle washing process for business wear was developed
that uses special enzymes with high activities below 20 °C. This low temperature washing process
leads to reduced shrinkage, seam pucker and crease formation compared to dry-cleaning processes
using organic solvents and common wet-cleaning processes. However, decreased soil removal
caused by a reduced washing temperature of 6 °C was only partially compensated by more flow
mechanics and the simultaneous use of enzymes. Although the low temperature washing process
achieved good results against food stains, additional spotting procedures were still necessary for
pigment- and fat-containing stains.
A solution for improving soil removal is the integration of thermo-sensitive soil release systems into
the low temperature washing process. Thermo-sensitive polymers with LCST properties (LCST: Lower
Critical Solution Temperature) are suitable for this application. Hydrophobic interactions between the
polymerchains dominate above the LCST. In consequence, strong adhesion to hydrophobic fibers
results. Below the LCST hydrophobic interactions strongly decrease and the polymer becomes hydrophilic, which results in weak adhesion to the hydrophobic textile surfaces. In addition, solubility of
these polymers increases below the LCST and consequently polymers are easily removed together
with the soil from textile surfaces. Above the LCST, e.g. during finishing processes, polymers adhere
to the textiles surface and act as a soil release layer. The presentation summarizes the achieved
results of this research project.

Simple and quick hygiene monitoring method for solvent based reprocessing
Einfache Schnellmethode für das Hygiene-Monitoring Lösemittel-basierter Aufbereitungsprozesse
Ole Rigbers, Markus Wehrl, Jürgen Bohnen
wfk
Abstract
Aqueous reprocessing of sensitive and complex textiles (e.g. business dresses, wool-containing
textiles) could lead to negative changes like shrinking, felting or creasing. Hence, these textiles are
usually cleaned in solvent based processes. Up to date hygiene monitoring of solvent-based reprocessing is usually carried out by using contact-plates. This procedure is time-consuming, cost-intensive and the evaluation can only be performed by external microbiological laboratories.
Aim of the presented wfk project was the development of a quick, in-house process control for
the evaluation and documentation of hygiene in solvent based cleaning processes. The chosen
approach based in the development of a hygiene monitoring method based on the inactivation
of enzymes which correlates with the germ reduction of the cleaning process. The inactivation of
relevant microorganisms in different solvents [e.g. tetrachloroethylene (PERC), hydrocarbon solvent,
decamethylcyclopentasiloxane (D5), SolvonK4], cleaning intensifiers and hygiene additives was
investigated initially in laboratory scale experiments. The results of these experiments provided the
basis for the selection of suitable enzymes (esterase and urease) used for the novel monitoring
method. Assessment of the enzyme activity was carried out by observing the color-development
of the enzyme-monitors after addition of the appropriate chromogenic substrate. Enzymes were
successfully immobilized on the textile-monitors via covalent binding in order to prevent their detachment. The enzyme concentration on the monitors was adjusted in a way that the color-reaction of the
enzyme-monitors correlated with the inactivation of the microorganisms. After a multitude of smalland large-scale experiments with the enzyme-monitors it was demonstrated that the enzyme-monitors displayed similar inactivation kinetics related to the whole solvent cleaning process compared
to relevant microorganisms. Thus, on the basis of an enzyme based color change it is possible to
judge the hygienic quality of reprocessing within a short time and without the services of external
laboratories. The potency of this newly developed and low-priced hygiene monitoring-system for
solvent-based cleaning processes was proved in a variety of applications.

Abstract
Textile services are customer-oriented services which provide care of durable textiles in a way which
is both environmentally friendly and product friendly, together with the flexible application of these
textiles and ensuring that the investment on the part of the user is cost efficient.
For providers of textile services these aspects can, in the interests of sustainable and successful
business operations, be divided into the following areas of activity:
• efficient use of resources and energy
• products and services
• profitability and competitiveness.
Ongoing investment in buildings and machinery is only one example of energy-efficient operations
on the part of Alsco Berufskleidungs-Service GmbH. For example, the country-wide standardisation
of washing programmes both saves resources and conserves the environment.
In terms of the products which it applies, in addition to their functionality and wearing properties
Alsco also attaches great priority to socially responsible production. In this respect Alsco relies on
information from suppliers which provides the service provider with essential details of the textile
chain and production conditions.
Alsco ensures the future profitability of the company with a training initiative and internal employee
development programmes, and at present 32 young people throughout the country are starting their
occupational careers with Alsco. Providing personal customer service in each individual location and
dealing fairly with customers is for Alsco the key element in sustainable and successful business
operations. Continuous process optimisation together with regular customer surveys are only two
measures which are intended to ensure a high level of customer satisfaction.
For textile services sustainable operations form the core of the service cycle. In addition, providers
of textile services also help their suppliers and customers to act sustainably by ensuring that textiles
have a long product life and that resources are used responsibly.

Abstract
Menschen haben Angst vor spektakulären Ereignissen wie Naturkatastrophen gleichwohl ihre
Eintrittswahrscheinlichkeit relativ gering ist. Alltägliche Risiken, wie sie zum Beispiel verseuchte Textilien bieten können, werden hingegen kaum wahrgenommen. Dies belegen diverse Verbands- und
Marktforschungsstudien der letzten Jahre. In seinem Vortrag präsentiert Dr. Andreas Marek einige
der eindrucksvollen Ergebnisse mit dem Resümee, dass die häusliche Wäsche von Berufskleidung
erhebliche Risiken für Hygiene, Sicherheit und Umwelt darstellt:
• 60% der Mitarbeiter von Arztpraxen nehmen ihre Arbeitskleidung zur Aufbereitung mit nach Hause,
•
52% trennen ihre Arbeitskleidung nicht immer von ihrer persönlichen Kleidung,
• 50% tragen ihre Arbeitskleidung auf dem Arbeitsweg,
• 68 % verwenden Weichspüler und 58 % verwenden Fleckentferner, durch die die Schutzeigenschaften von Arbeitskleidung reduziert werden,
•
51% halten sich nicht an die Dosierungsvorschriften der Waschmittelhersteller.
Validierte industrielle Prozesse, wie sie der Textil Service einsetzt und die in stetiger Forschungsarbeit
permanent optimiert werden, reduzieren die Gefahr der Verbreitung von Viren, Kontaminationen und
der Ausbreitung von Infektionen. Eine seiner vorrangigen Aufgaben sieht der Wirtschaftsverband
Textil Service (WIRTEX) e.V. daher in einer verantwortungsvollen Aufklärungsarbeit. Für die Textilforschung ist der Vortrag von Dr. Marek ein Beleg für die praktische Umsetzung ihrer Forschungsarbeit.

Abstract
Supply chains can be complex constructions. Due to the multi-tier character of Textile Service Supply
chains with many thousands transactions (material, information, cost accounting) per day the traceability of goods and transparency of workflows is of major importance.
As availability of textile articles in daily operations is fundamental, the use of laundry-dedicated UHF
(Ultra-High-Frequency) RFID transponder modules (backed up by a data-focused ERP-Software
Management System) provides a holistic view and single piece real-time identification of textile
goods. The introduction of multiple or even permanent monitoring of inventory in different locations
(upstream stock- and processing units to downstream usage points) can help strengthen resilience
against classic challenges in Textile Services, e.g. volatility of demand, out of stock situations etc..
With the technical assistance of an innovative dispensing/collection/counting/ordering system environment for textile goods transparency can be achieved, thus resulting in more effective business
management and even new business cases for the industry.

Abstract
Healthcare expenditures are under strict control in most European countries. Cost per services are
being reduced wherever possible and textile service companies have not always anticipated this
economic scenario. This results in losing customers or reducing the service with a bad effect on
customer satisfaction or hygienic control. This presentation discusses the key drivers for hospitals
and textile service companies in the garments rental business and describes a win-win scenario for
both parties with a strong customer-supplier relationship as an outcome.

presence visually, intended to provide conspicuity of the user in high-risk situations under any light
conditions by day and under illumination by vehicle headlights in the dark.
The old standard EN 471 was related to „professional-use“. The new standard ISO 20471 is not further
related to „professional-use“ - but is related to „high visibility“ for „high risk“ situations.
The harmonized visibility standards EN 1150 and EN 13356 are still related to „non-professional use“.
The current revison of these standards will consider also a risk related change. The new standards
will define characteristics for „enhanced visibility“ for „medium risk“ situations.

technologies and hygiene management in Krefeld (2004-2008). Since 2008 he is project engineer
in the department process engineering at wfk. Main tasks of his work are optimization of washing-,
drying- and finishing processes in industrial laundries, especially on efficient use of water-, energyand CO2 consumption values.
Abstract
Aim of the investigation was to compare and visualise the capacity of soil uptake on service dust
control mats in comparison to DIY market mats. For the investigations three mats of different manu
facturers were used (two service mats, one DIY-market mat). Because of reproducibility reasons a
standardised carpet-pigment soil was used and applied by a step simulator, which simulates the
human walk at assured constant walking conditions. Soil uptake was determined by applying colorimetric measurements (CIE-Lab) on the mat´s flooring as well as gravimetric measurements of the
used shoes. The shoes were soiled and weighted prior walking over the dust control mat.
Investigations show highest soil removal from the used shoes as well as highest soil uptake capacity
on un-used service dust control mats, followed by service mats which were aged (50 and 100 washing cycles). Lowest soil uptake and soil removal from the shoe showed the DIY market mat which
even can not be washed.
Further investigations on dust control mats were carried out regarding slipping properties at various
conditions (temperature, different floorings, moisture contents etc.)

Abstract
Today a laundry is confronted with challenges resulting from social developments of globalization, individualization of the customers, demographic changes and shortage of natural resources.
The variety and volume of articles, textiles and processes continue to increase. The Kannegiesser
PowerTrans represents a new approach in batch washer technology. It offers flexibility comparable to
that of washer extractors, whereby the hourly performance is as high and the consumption as low as
it can be expected from a modern high-performance batch washer. The load mix and sequence can
optimally be adjusted to the logistic chain and the requirements of the laundry.
Optimized drum design, precise manufacturing methods and intelligent controls enable operational
flexibility. An incompatible batch mix does not consequently lead to empty compartments and loss
of performance.
The pick-up and drop mechanics of the PowerTrans leads to a consistent wash and rinse result,
reproducible and independent from the batch size. This has been confirmed by an institute after
detailed examinations in the field.
The profits of this flexibility can be summarized in 5 points:
• Flexibility as known from washer extractors: High output and low consumption as it can be
expected from a modern batch washer
• Standing bath rinsing machine: Less or no empty compartments even with an incompatible
linen mix
• Standing bath rinsing: Precise rinsing and finishing without average determination
• Consistent wash and rinse results, independent from the batch size: Tested and confirmed in the
range from 25% to 110% of the nominal loading
• Modules hermetically divided from each other by doubled sealing’s: No liquor transfer possible

Milnor’s PulseFlow Technologie
Yves Dabrowiecki studied at the Royal Military Academy in Brussels and obtained a Master degree
in Social and Military Sciences in 2002. After three years as young officer in the Belgian Air Force, he
became an assistant lecturer at the Department of Economics, Management and Leadership at the
Military Academy and combined this function with complementary studies at the VUB University in
Brussels. In 2009 he obtained a Bachelor degree in Applied Economics at the VUB, and that same
year he served as deputy head of dispatch at the 15th Wing Air Transport Unit, managing air transport
operations. In May 2012 he joined the experienced and enthusiastic Pellerin Milnor Corporation team
in the Brussels office as a Sales Manager where he brought his interpersonal, technical, managerial
and language skills to contribute to Milnor’s objectives, being a stable, capable, accountable and
progressive company.
Abstract
In order to best explain how PulseFlow Technology works, let us briefly review how tunnels have
processed linen to this point.
There have been two schools of thought. The first is, counter-flow washing which produces cleaner
linen through superior dilution. The second is standing bath washing which cleans linen through
longer exposure to chemistry.
Counter-flow tunnels start with dirty linen in the load end of the machine and each transfer exposes
the linen to a cleaner bath. As the linen moves into a cleaner bath, the water in turn becomes more
soiled as it flows to the front end where it finally flows down to the sewer. Every Milnor CBW uses
this method. It is accentuated by the dilution achieved from true top transfer; where all free standing
soiled wash liquor remains in each module during transfer.
Standing bath washing relies on chemistry to wash linen (combined with mechanical action). All
wash liquor, chemistry and linen move forward together during each transfer in the wash zone. A
standing bath wash tunnel must have a counter-flow rinse zone to remove the residual chemistry
and soiling in the linen. For classic standing bath washing to be effective you have to purge and refill
the modules at the end and beginning of each zone.
PulseFlow Technology is the unprecedented merger of these two schools. It combines the strengths
of counter-flow washing without diminishing the chemical potency. This is only possible in a Milnor
CBW because of its complete double shell design and “True top Transfer”. This allows for standing
bath washing with intermittent, high velocity counter-flow rinse just before each transfer.
In addition to the PulseFlow technology, 3 new features were introduced:
1) There is only one central water tank for the entire system, mounted under the load scoop
2) There is a high velocity recirculating pump on the 1st module
page 79
Textile
Cleaning
Yves Dabrowiecki
Milnor International, Brussels, Belgium
3) All zones have been merged causing each module to work as “dual-use” modules
PulseFlow Technology requires the use of only one tank for the CBW. The PulseFlow Tank is located
on the frame under the load chute and it holds a mixture of clean water from the extraction tank and
fresh water make-up. It eliminates the need for the formal externally mounted wedge wire lint filters.
This is the only source where the system introduces fresh water. An electronic flow-meter guaranties
absolute accuracy of fresh water supply.
RecircONE® is the high velocity pump on module one. Continuously recirculating the wash liquor in
module one, through the load chute, during the washing cycle at a rate of 440 l/min. This creates
the optimum environment for linen to be introduced into the washing process. ReCircOne instantly
doses the linen with the wash liquor allowing the washing process to start in module one. With the
high flow rate there is no fear that linen will get stuck in the chute, wasting valuable processing time.
ReCircOne acts as a catalyst agitating the chemistry and accelerating its effectiveness. This is important for healthcare installations because you can now escalate temperatures to as high as 60 C in
the first module without protein staining.
The real genius of PulseFlow Technology is the elimination of separate “zones” inside the CBW.
Each module in a PulseFlow CBW takes full advantage of its potential to perform its specific function. The “dual-use” modules now act as both a wash and rinse module. Because of welded dividers
separating the wash liquor in every module, without a wearable seal below the water line, each
module works like a separate step inside a washer extractor. For the first approximate 75% of time
between each transfer, the linen is washed in a standing bath which is followed by the high velocity
rinse for the remaining approximate 25%. The wash liquor then flows to the sewer from either module
one or two depending on the classification and needs of the customer.
Gentle drying and finishing processes
Textilschonung in Trocknungsprozessen

Christian Szameit absolvierte ab 2004 eine Ausbildung zum Industriekaufmann bei der Hettich Management Service GmbH in Kirchlengern, wo er anschließend ein Jahr im Bereich Produktmanagement und Marketing tätig war. Von 2007 bis 2012 studierte er Maschinenbau an der Fachhochschule
Bielefeld mit dem Schwerpunkt auf Produktions- und Kunststofftechnik. Während seines Studiums
war er als Werksstudent in verschiedenen Abteilungen der Paul Hettich GmbH & Co. KG in Kirchlengern beschäftigt. 2013 begann er als Vertriebsingenieur im Bereich Flach- und Trockenwäsche bei der

Abstract
Practical tests in a laundry have shown that the chemical fibre damage is increased by up to factor
3 by the drying process compared to the washing process. As textiles form the largest cost pool
(besides labour costs) in a laundry, gentle drying can develop enormous cost savings. The key is to
avoid over-drying.
The highest level of drying technology is represented by the Kannegiesser ECO2power system for
PowerDry batch dryers. By continuously measuring the linen temperature with InfraTouch, together
with supply air and exhaust air temperature, the optimal process adjustment is realized. The result is
a maximum air circulation rate and an ideal distribution of the linen. The results are significant energy
savings and exact determination of the material temperature. Both lead to an optimal drying process
and accurate predetermined drying point.
page 80
Kannegiesser successfully introduced the HPM ironer that uses a heating band made of stainless
steel with a highly flexible adaptation to the roll diameter. The FlexiCare package allows a quick and
infinitive temperature adjustment and supports a better consistency in degree of linen whiteness
and colour. When producing light articles a reduction of the ironing temperature helps to avoid
over-drying, save energy and increase linen lifetime. The HPM also is the ideal ironer for low temperature ironing processes.
The new Kannegiesser finisher generation XMT provides new possibilities for controlling the air
stream, mechanical stretching forces and temperature control. Using the counter air flow principle
the energy in is transferred from module to module and cannot escape the system. Overheating of
the fabric in the hot air zone is prevented by means of incremental temperature-control. The textiles
are treated gently and colour changes are avoided more effectively. In summary this leads to energy
savings of approx. 25%.

Abstract
In general the performance of important processes has to be controlled for permanent guarantee of
quality. For this validations have been established in different sectors. Descriptions of validations for
the pharma sector, the food sector, the reprocessing of medical instruments and others are available.
For guarantee of textile hygiene within the reprocessing of textiles in commercial laundries the RABC
system was established which is described in the EN 14065. This hygiene management system
claims the determination of critical control points (CCP) and their validation. Ordinarily the disinfecting
washing processes are determined as single critical control point in commercial laundries and most
important process step for disinfection of the textiles. For validation of these washing processes the
EN 14065 claims the description, control and documentation of relevant process parameters and
their tolerances. A possible procedure for validation is described within the annex F of the actual
draft of the EN 14065:2014. The life-cycle model for validation consists of design qualification,
installation qualification, operational qualification and performance qualification with different redirection of responsibility also to the machine manufacturer and detergent supplier. The capacity of
the disinfecting washing processes can be assessed by the means of experience (“historical data”)
and should be basically investigated if no experiences with the washing procedures are present.
Only very little literature is available which lists details and procedures to approaches of validation
of disinfecting washing processes (e.g. CFFP 01-04 of the department of health in UK). Therefore a
working group was founded which aims to set up details for validation of washing processes within
a guidance document. In the working group e.g. descriptions of methods, details to measurements
of process parameters, conditions for reduced testing contents as well as check lists for installation,
operational and performance qualifications shall be developed.

Abstract
The reprocessing of hospital laundry and laundry of healthcare facilities is mainly performed in commercial laundries which have a structural separation between a dirty and a clean site. The delivery of
the dirty laundry and the loading of the washing machines are performed on the dirty site, the further
processing and the expedition of the laundry is done on the clean site. It is required for an adequate
hygiene that the transfer of microorganisms from the dirty to the clean site will be minimized to avoid
contact of staff members on the clean site with pathogenic microorganisms and recontamination
of textiles on the clean site. Hence, it is necessary to disinfect all items (mainly roll containers and
medical trolleys) which switch from the dirty to the clean site. For this, containerlocks are primarily
used in commercial laundries. In these containerlocks the items are sprayed with disinfection agent
and some of them are equipped with prior washing- and/or heating function. The disinfection
performance of the containerlocks was so far tested with end product controls (e.g. contact samples,
RODAC).
The wfk-institute has developed process challenge devices with microorganisms which enable an
efficient and effective process control of the disinfection performance of the containerlocks. The
process challenge devices are developed and tested on the basis of methods for similar applications which are already published, i.a. DIN 58955-4 “Decontamination equipment for medical
use” and AK-BWA “Arbeitskreis Bettgestell- und Wagen-Dekontaminationsanlagen”. The process
challenge device consists of a small metal plate which is centrally soiled with Enterococcus faecium
ATCC 6057 in bovine serum albumin- mucine- starch. After the application of the process challenge
devices in the containerlocks the residual germ concentration will be compared to the initial cell count
and the resulting reduction factors will be calculated. Laboratory experiments in which the metal
plates were coated with appropriate disinfection agents as well as field trials in modulated containerlocks demonstrated the suitability of these process challenge devices for testing the disinfection
performance of containerlocks. Consequently, these process challenge devices are used in hygienic
investigations for the certification of commercial laundries with the wfk-seal for textile hygiene.

Fluorcarbon resins - an echa-logical problem: How will we be protected in the future?
Fluorcarbonharze - ein ECHA-logisches Problem: wie können wir uns in Zukunft schützen?

Abstract
Repellency against water and other fluids like acids, bases, oils and solvents is an important property
of textiles in many fields of application. From water repellent textiles like outdoor garments to high
visibility clothes for personal protective equipment (PPE), from textiles resistant against chemicals to
OP-garments: many fabrics are equipped with fluorocarbon resins to fulfil the requirements in the
field of their application since decades. Up to now the most carbon resins were manufactured on
the basis of C8-chemistry. Members of this class of substances are in discussion since a few years.
In 2006 started the U. S. EPA PFOA Stewardship Program to which the world’s major fluoropolymer
and fluorotelomer manufacturers agreed voluntarily. This program commits industry to stop the
emissions of PFOA and related compounds (poly- and perfluorinated C8-alkyl compounds and
derivatives) completely until the end of the year 2015. Now the European Chemicals Agency (ECHA)
has prepared a proposal for a restriction of PFOA and related compounds which equals a complete
ban of the mentioned substances in the EU. Since this might also influence shorter fluorinated
alternatives the normative requirements of today’s European and international standards for high
performance textiles could not be fulfilled in the future.

Abstract
Poly-and perfluorinated chemicals (PFCs) have been manufactured for more than 50 years for use
in various applications including nonstick cookware coatings, waterproof outwear, fire extinguishing
foam and the treatment of paper, e.g., to improve moisture barrier properties. But besides the desired
physical properties of PFCs they also show environmental persistence, bioaccumulation, global distribution and toxicity. Recent reports about the widespread presence of perfluorinated chemicals in
the environment have raised increasing concern especially since several scientific studies disclosed

that PFCs are present in tap water from where they end up in human blood.
Launched in 2011, the Detox campaign from Greenpeace has exposed links between global textile
brands, their suppliers and the environmental pollution around the world. This has strengthened
public interest in the use of fluorine-free chemistry for water repellent coatings.
Compounds based on oils, fats and waxes have been employed as water repellents long before
PFCs were introduced. However, theses additives do not satisfy today´s customer demands since
wash durability, good abrasion resistance and breathability are essential factors for textile goods.
Moreover, in textile care applications a high exhaustion rate is also required to avoid waste water
contaminations.
Recent alternatives to PFC chemistry are based on polyacrylates, silicones and polyurethanes. Altogether, these three polymers form a matrix that allow for an almost unlimited amount of variations by
chemistry. Furthermore, the desired properties can be tuned by the polymer architecture.
Nowadays, several suppliers offer PFC-free durable water repellents. CHT has developed a novel
methodology that employs fluorine free chemistry and we are proud to announce our new product
line under the trade name zeroF.
We belief, that the demands of authorities, NGOs and finally the consumers will enhance the existing
trend towards a more sustainable chemistry.

birgt ein großes ökologisches Potenzial. Ziel eines Projektes der Allianz für nachhaltige Beschaffung
war es daher, typische Reinigungsarbeiten in der Unterhaltsreinigung von öffentlichen Gebäuden
zu ermitteln, diese unter Aspekten der Nachhaltigkeit zu prüfen und daraus Empfehlungen zur
Verringerung möglicher Wirkungen auf Umwelt und Gesundheit abzuleiten. Der Schlüssel dafür liegt
vor allem in der Verringerung der entstehenden Verschmutzungen, der Erstellung eines optimierten
Leistungsverzeichnisses, regelmäßige Schulung des Reinigungspersonals und die Verwendung
umweltfreundlicher Reinigungsmittel.
Um die öffentliche Beschaffung einer nachhaltigen Reinigungsdienstleistung unter Verwendung
umweltfreundlicher Reinigungsmittel zu erleichtern, wurde ein Leitfaden für die Anwendung in der
Verwaltung entwickelt, dessen Anforderungen bei der Ausschreibung in die Leistungsbeschreibung
integriert werden können.
Der Leitfaden verfolgt dabei folgende Ziele:
• geringere Auswirkungen für die Umwelt bei der Auftragserfüllung durch Verwendung von
geeigneten Dosierhilfen und regelmäßige Schulung des Personals hinsichtlich der Anwendung
der Produkte
• Verringerung oder Vermeidung der Gefahren für die Umwelt und die menschliche Gesundheit
durch gefährliche Stoffe durch spezielle Anforderungen an den Auftragsgegenstand.
Bereits bei der Auswahl der zu verwendenden Produktarten kann ein entscheidender Einfluss auf die
Umweltverträglichkeit der Reinigungsdienstleistung genommen werden. So sollte zum Beispiel auf
den Einsatz von Beckensteinen und Duftspendern verzichtet werden.
Zusätzlich ist die konkrete Auswahl des Produktes hinsichtlich der enthaltenen Inhaltsstoffe und
dessen Dosierung von Bedeutung. Daher beinhaltet der Leitfaden eine Bewertungsmatrix für
gewerbliche Reinigungsmittel, welche sich an den Vorgaben des EU-Umweltzeichens für Allzweckund Sanitärreiniger orientiert.

Verbesserung der Compliance bei der Oberflächendekontamination in Krankenhäusern
Compliance improvement of surface decontamination in hospitals
Jan Ohme
Abstract
Cleaning and disinfection of surfaces in hospitals are increasingly regarded as critical factors of
hospital hygiene contributing to reduction of nosocomial infections.
Significant discrepancies however remain between scientific/academic requirements of surface
decontamination and practical implementation. The reasons are discussed and approaches to
solutions are introduced.
In view of the importance of identification of hygienically critical surfaces a hygiene risk based categorisation in combination with appropriate disinfection timing is suggested.
A complementary change of hygiene techniques is required to reach a higher level of compliance
with surface hygiene standards as main influence factors in reducing hospital infections.
With respect to technical implementation three empirical hygiene risks have been identified related to
surface disinfection:
1. Routine daily disinfection by wiping patient-side surfaces in wards
2. Final disinfection of isolation rooms after discharge...
3. Surface disinfection of operating rooms
Each of these risks is discussed regarding risk details such as disease related differentiation of
disinfectants and use of disposable disinfection wipes.
In addition to the technical considerations the influence of frequent organizational and structural
deficits on disinfection compliance is highlighted and possible solutions are presented.

Abstract
Smartphone and tablet touchscreens are well known pathogen carriers in clinical environments.
However, despite a rapidly growing number of smartphones worldwide, little is known about bacterial
contamination of touchscreens in non-clinical settings. Such data are needed to better understand
the hygienic relevance of these increasingly popular items.
In a recent study with 60 smartphones (Egert et al. (2015), Folia Microbiol. 60: 159), the average bacterial load of uncleaned touchscreens was determined as 1.37 ± 0.33 CFU cm-2 by surface sampling.
Touchscreens wiped with microfiber cloths or alcohol-impregnated lens wipes contained significantly less bacteria than uncleaned touchscreens, i.e. 0.22 ± 0.10 CFU cm-2 and 0.06 ± 0.02 CFU cm-2,
respectively. Bacteria isolated from cleaned and uncleaned touchscreens were identified by MALDI-Biotyping. The vast majority of the identified bacteria were typical human skin, mouth, lung and
intestinal commensals, mostly affiliated with the genera Staphylococcus and Micrococcus. 50% of
the identified species were opportunistic pathogens, suggesting the potential role of touchscreens
as pathogen carriers also in non-clinical environments.
Very recent data largely corroborated the above mentioned bacterial load and species spectrum of
uncleaned touchscreens. Among 100 investigated phones, no contamination with MRSA was found.
However, a significant influence of the sex of the user and the use of hand lotion, a protective foil
and a smartphone cover on the bacterial load of the touchscreens became obvious.

sind Detailwissen bezüglich Mechanik, pH-Werteinstellung und Verhalten gegenüber verschiedener
Inhaltsstoffe. Was also tun, um schnell die für die Reinigung und Pflege wichtigen Parameter vor Ort zu
prüfen, um eine falsche Reinigung bzw. eine Schädigung im Vorfeld zu verhindern. Gleichzeitig kann
dasselbe Verfahren angewendet werden, um Schmierfilme zu erkennen und schnell zu beseitigen.

Abstract
Gerade bei der Reinigung großer Verkehrsflächen in unterschiedlichsten Branchen bringt der Einsatz
von Scheuersaugmaschinen große Vorteile, zeichnen sich diese doch durch große Flächenleistungen aus. Im Vergleich zur Verwendung von Flachwischgeräte verringert sich der Arbeitsaufwand um
das 10-fache, was bei mehr als 80 % Personalkostenanteil in der Reinigung eine deutliche Kostenreduzierung zur Folge hat. So kommt es nicht von ungefähr, dass der Einsatz von Scheuersaugmaschinen wachsende Beliebtheit erfreut.
Reinigungsmittel für Scheuersaugmaschinen enthalten üblicherweise neben anderen Bestandteilen schaumarme Tenside, da es sich gezeigt hat, dass zu starke Schaumbildungen im Abwassertank zum Abschalten der Maschine führt. Die eingesetzten Tenside sollen in erster Linie Schmutz
unterwandern und emulgieren. Gerade bei der Reinigung von Barfußbereichen in Schwimmbädern
mit hohen Oberflächenrauhigkeiten hat sich in der Praxis gezeigt, dass der Einsatz von Tensiden
eine schlechtere Trocknung und schnellere Wiederanschmutzung der Flächen bewirken können. Die
neu entwickelten Reinigungsmittel der vorgestellten Serie kommen vollständig ohne Tenside aus.
In Untersuchungen und in der Praxis konnte gezeigt werden, dass Trocknungszeiten verkürzt und
Wiederanschmutzungen reduziert werden konnten. Mittlerweile sind die vorgestellten Reinigungsmittel in der Schwimmbadreinigung, aber auch in der Reinigung von Verkehrsflächen von Supermärkten
und Diskountmärkten etabliert. Im letzteren Fall konnte dadurch auch die Reinigung während der
Öffnungszeiten optimiert werden.

Abstract
Aufgrund des demographischen Wandels gibt es immer weniger qualifiziertes Reinigungspersonal.
Bei der professionellen Gebäudereinigung wird die traditionelle „leistungsorientierte Reinigung“
mehr und mehr durch eine „ergebnisorientierten Reinigung“ ersetzt. Dabei liegt es in der Hand des
Mitarbeiters, relevante Verschmutzungen zu erkennen und zu beseitigen und somit den definierten
Qualitätsstandard widerherzustellen. Bei der Büroreinigung entfallen 70 Prozent der Arbeiten darauf,
Fußböden zu reinigen und Abfälle zu entsorgen. Das Teilprojekt »Robotergestützte Reinigung« des
vom BMWi geförderten Verbundprojekts AutoPnP (www.autopnp.com) beschäftigte sich mit der
Entwicklung von Lösungen, um Serviceroboter für diese Tätigkeiten einsetzen zu können.
page 93
Aktuelle Entwicklungen in der Reinigungsrobotik fokussieren auf die Nass- und Trockenreinigung
großflächiger Umgebungen wie Konferenzräumen, Supermärkten oder Turnhallen. Dabei führen alle
existierenden Produkte eine komplette Reinigung der vorgegebenen Fläche durch und besitzen nicht
die Fähigkeit, Verschmutzungen zu erkennen und diese gezielt zu beseitigen.
Im Rahmen von AutoPnP wurde der Roboterassistent Care-O-bot 3 (www.care-o-bot.de) weiterentwickelt, um genau diese - für die ergebnisorientierte Reinigung den damit verbundenen effizienten und
wirtschaftlichen Einsatz des Roboters essentiellen - Funktionen bereitzustellen. Insbesondere wurde
ein automatisches Werkezugwechselsystem integriert, das es dem Roboter ermöglicht, sowohl eine
Roboterhand für das Greifen von Papierkörben als auch einen Staubsauger für die Bodenreinigung
anzuschließen. Zudem wurden Software-Komponenten zur systematischen Inspektion der zu
reinigenden Räume, zur automatischen Schmutzerkennung auf dem Boden, zur Schmutzbeseitigung und für das Leeren der Mülleimer entwickelt und auf dem Roboter in Betrieb genommen und
in der Praxis getestet. Im nächsten Schritt sollen die entwickelten Steuerungskomponenten auf
einen spezialisierten, produktnahen Reinigungsroboter transferiert und damit die Grundlagen für die
Produktumsetzung geschaffen werden.

Punkten kann man Nachhaltigkeit den wirklich festmachen? Wenn wir das ganze aus der Sicht eines

ihren Preis haben. Und da ist die Krux begraben. Es soll alles günstiger werden, aber trotzdem in

Ozone locks for disinfection in the food industry
Ozonschleusen zur Desinfektion in der Lebensmittelindustrie
Andreas Schönweiz
Anseros GmbH, Tübingen
Abstract
The food and beverage industry needs billions of liters of water every day for washing, processing,
cooking, cleaning of food and many more. This water must be free of any contaminants. Traditionally, chlorine has been used for water treatment, but nowadays the food industry has recognized
the huge potential of ozone technology for disinfection. Due to the potential risk of toxic chlorine
residues in water, ozone is considered to be a safe and environmentally benign alternative. Further,
gaseous ozone can be used for the sterilization of packing materials or as a preservative for food
products, such as eggs, fruits and vegetables or fish. For this purpose, ozone locks offer an elegant
and flexible way to treat large volumes of products at the same time. We also provide and develop ready-to-use ozone systems for versatile sterilization and laundry purposes. This implies, for
instance, the sterilization of bottles and wine barrels as well as endoscopy equipment and surgical
instruments, or the cleaning of clothes in the field of personal and occupational hygiene.

Abstract
Food residues, biofilms and bacteria colonies provide a high risk to product quality in modern food
industry, clinical environment or other critical area. Therefore effective cleaning and the confirmation
and documentation of cleanliness are of high importance. Traditional microbiology like agar-contactplates and swabbing are the common methods in industry. They provide a qualitative response but
it takes up to 2-3 working days to get the result. For many processes this is too long as decisions are
already made.
The ATP bioluminescence detection as described in DIN 10124:2009 is a very sensitive method to
provide results in real-time. It combines ease-of-use, real-time results and documentation in one test.

Abstract
In hygiene demanding areas such as food industry, pharmaceutical industry, cosmetics and health
care facilities routine cleaning and surface disinfection have to be performed to ensure high hygiene
requirements. The manner and frequency these procedures are conducted are defined and documented in hygiene and disinfection plans. Moreover it is indispensable for the responsible personnel
to perform hygiene controls of surface disinfection. These controls serve as a verification and docu
mentation for successfully performed cleaning and disinfection procedures (end product control).
Until now, there was no adequate method available to control the process of surface disinfection
itself (process control). An innovative method enabling an easy, secure and rapid process control for
page 96
disinfection of surfaces is developed. Based on dye-encapsulating proteoliposomes a functional
model for a biomonitor was developed providing an in-house self-monitoring method. The test monitor is placed on the surface to be disinfected. By the action of the disinfectant the proteoliposomes
are destroyed likewise to the microorganisms and the included dye is released. The quality of the
disinfection process can then be assessed by the intensity of fluorescence of the released dye that
is visualized by UV-light. This fast method facilitates an instantaneous on-site self-monitoring directly after the disinfection process and enables to proof the required process reliability and hygienic
quality. The presentation gives an overview of the achieved research project results.
Development of thermally switchable dosing systems for a LAMP-rapid detection of MRSA
Entwicklung thermisch schaltbarer Dosiersysteme für einen LAMP-Schnellnachweis von MRSA
Aaron Overlöper, Edyta Stec

Abstract
Due to a lack of hygiene at least 900,000 hospital-acquired infections occur in Germany each year,
of which 30,000 are fatal. Methicillin-resistant Staphylococcus aureus (MRSA) represent with 25 %
one of the most common causes of nosocomial infections. Hence, the reliable inactivation of MRSA
on surfaces is of essential importance in the control of nosocomial infections. The compliance and
control of hygiene leads to an efficient and measureable prevention of MRSA infections. Therefore,
the regular control of the successful disinfection possesses an increasing importance. Currently,
sensitive rapid methods for self-monitoring of MRSA inactivation are not available. Conventional
controls are done using selective contact plates for sampling of surfaces. These plates have to be
incubated and evaluated by external microbiological laboratories. This method is cost-intensive and
provides results within 3 days at the earliest. A rapid and sensitive method for the detection of MRSA
is the polymerase chain reaction (PCR). The PCR method is highly specific and provides results within
1 hour. However, the PCR is highly sophisticated to perform; the method requires the exact addition
of various reagents at defined temperatures. Likewise, this method is also performed by external
microbiological laboratories. The loop mediated isothermal amplification (LAMP) is a one-step PCR
technique with a high specificity, sensitivity and velocity. In contrast to the PCR in which the reaction
is carried out with a series of alternating temperature steps or cycles, the LAMP is carried out at a
constant temperature, and does not require expensive devices as the classical PCR.
In the presented research project we developed a method suitable for a rapid self-monitoring of
MRSA by the use of a LAMP-PCR in combination with thermally switchable dosing system, which
enables an easy handling for personnel engaged in surface disinfection without the help of external
professionals. The presentation gives an overview of the achieved research results.

Aufbereitung von Reinigungstextilien - effizient und hygienisch sicher
Reprocessing of cleaning textiles - efficient and hygienically safe
Manuel Heintz
wfk
Abstract
The reprocessing of cleaning textiles e.g. mops, cleaning cloths, etc. plays an important part for
the professional cleaning and maintenance. A professional and appropriate cleaning and maintenance which yield in sufficient results for all parties is only possible with technically impeccable and
cleaned textiles.
Thereby it has to be considered that cleaning textiles are nowadays technical products for which special and necessary cleaning and maintenance procedures exist. However normal washing processes
are often used due to lack of knowledge. This leads to not sufficiently cleaned textiles as well as to a
decrease of durability. At worst this yeilds insufficient cleaning results. Especially for the resprocessing of hygienically relevant cleaning textiles an adequate hygiene status has to be guaranteed by
proper procedures.
For guarantee of a good reprocessing quality it is necessary to determine and control the relevant
process parameters. Such process parameters are e.g. water quality, dosage of detergent, liquor temperature, amount of load, pre-cleaning. Additionally the durability of the cleaning textiles can suffer
extremely by a wrong application. Ideally the reprocessing is implemented in a quality management
system to ensure a permanent reprocessing quality. For hygienic concerns the RABC system on
the basis of EN 14065 is the best choice. Therewith a microbiological reprocessing quality can be
ensured. Although the EN 14065 was developed for commercial laundries the basics can be applied
for smaller reprocessing units.
Important informations to this topic can be taken from the FRT guideline „The proper reprocessing of
cleaning textiles“ (2014).

Abstract
Im Krankenhaus erworbene Infektionen sind seit langem ein Diskussionspunkt und zwar findet eine
solche Diskussion sowohl in der Fachwelt als auch in der Öffentlichkeit statt. Anhand von Berichten
wird im Vortrag gezeigt, dass nicht nur Hygienefehler im direkten Umgang mit den PatientInnen
sondern auch eine mangelhafte Aufbereitung von Medizinprodukten zu Infektionen bei PatientInnen
führen kann. Denn obwohl die gesetzlichen Vorraussetzungen als ausreichend angesehen werden
können, werden immer wieder Defizite bekannt, so zum Beispiel bei der Aufbereitung von Endoskopen. Im Vortrag werden einerseits einige Beispiele aufgezeigt, wie eine mangelhafte Aufbereitung
aussehen kann - nicht nur in Bezug auf die Endoskopie -, andererseits wird gezeigt, dass Vorschriften durchaus nicht immer befolgt werden.
Entwicklung von Reinigungsmitteln zur Entfernung von Biofilmen

Abstract
Biofilme stellen an verschiedenen Orten im Gesundheitswesen ein Risiko für Patienten dar. Unter anderem sind flexible Endoskope mit ihren langen Kanälen davon betroffen, aber auch die Reinigungsund Desinfektionsgeräte, in denen diese Endoskope aufbereitet werden (Kovaleva et al., 2013).
Die Reinigung der Endoskope besteht heute in den meisten Fällen aus einem manuellen und einem
maschinellen Teil, kann aber auch rein manuell - oder bislang noch selten - rein maschinell erfolgen.
Auf dem Markt werden verschiedenste Reinigungsmittel mit dem Anspruch der Wirksamkeit gegen
Biofilme angeboten. Diesen Anspruch unterstützende Daten werden jedoch kaum je geliefert.
page 102
In einem Projekt zur Entwicklung von Reinigern zur Entfernung von Biofilmen wenden wir unterschiedliche Methoden an, um die Wirkung der Reinigungsmittel zu charakterisieren. Die Aufzucht
von P.aeruginosa- und S.aureus-Biofilmen erfolgt dabei in Mikrotiterplatten und in Endoskopkanälen.
Die Abreinigung der Gesamt-Biomasse wird mittels Kristallviolett- und FITC-Färbung quantifiziert. Die
Quantifizierung zurück bleibender, vermehrungsfähiger Zellen erfolgt mit dem Turbidity Threshold
Assay (TTA, Mikrotiterplatten) oder klassisch (Endoskopschlauch). Schliesslich kommen auch neue
Methoden zur Visualisierung der Biofilmabreinigung zum Einsatz.
Erste Resultate zeigen, dass Reinigungsmittel, die Desinfektionswirkstoffe enthalten, zwar bessere
Werte im TTA haben können (Abtötung) aber in der Regel die Gesamtbiomasse, die viel EPS enthält
deutlich weniger gut abreinigen können. Parallel dazu durchgeführte Untersuchungen zur Abreinigung von koaguliertem Blut zeigen ein ähnliches Bild. Es hat sich weiter gezeigt, dass das in BiofilmLaboren häufig als Positivkontrolle angewandte Wasserstoffperoxid ungeeignet d.h. ungenügend
wirksam ist. Es wurde daher durch eine Mischung von je 1% NaOH, NaOCl, SDS und EDTA ersetzt.
Die besten enzymatischen Formulierungen sind bezüglich Reduktion der Gesamtbiomasse sogar
besser als diese neue Positivkontrolle.
Weitere Resultate werden gezeigt und diskutiert.
A standard for a „standard detergent“ - The gasoline approach to medical device detergents
Eine Norm für einen “Standard-Reiniger” - der “Benzin-Ansatz” für Reiniger für Medizinprodukte

Abstract
This paper discusses changing the approach to medical device detergent compatibility in a manner
similar to that adopted by the petrochemical industry. I can take my car (of any sort) to any fuel station
in the world and as long as I know whether I need petrol or diesel, I can refill my tank and drive away.
Without worry and without additional testing on my part. I can achieve something broadly similar with
a domestic automated dishwasher. Yet it would be difficult to do this with either a thermal washer-disinfector or an endoscope washer-disinfector and still comply with EN15883 or the manufacturer’s instructions. The presentation looks at the issues arising from such an approach and the
advantages and disadvantages.

Abstract
Dem Reinigungsprozess wird bei der Aufbereitung von Medizinprodukten eine große Bedeutung beigemessen. Das gilt sowohl für maschinelle als auch für manuelle Verfahren. Dennoch fehlen derzeit
einheitliche Bewertungsverfahren, wie sie z.B. bei der Beurteilung von Desinfektionsmitteln für die
Listung durch den Verbund für Angewandte Hygiene (VAH) vom VAH zugrunde gelegt werden.
Die DGKH-Sektion „Reinigung und Desinfektion“ hat sich deshalb zum Ziel gesetzt, diese Lücke zu
schließen und Experten aus Industrie und Testlaboratorien aber auch Hygieniker gebündelt und den
Arbeitskreis „Reinigungsmittel-Testung“ (AKR) gebildet. Dem von Frau Krüger geführten Arbeitskreis

Dieser AKR beschäftigt sich zunächst mit der Entwicklung eines Prüfmodells für die manuellen
Prozesse, in dem die wichtigsten Parameter variiert werden können.
Dazu zählen u.a. die Temperatur, Konzentration und Einwirkzeit des Reinigers, Testkörper und Prüfanschmutzung, aber auch der Einfluss einer Mechanik. So wurde das Prüfmodell der Ad-hoc-Gruppe
“Prüfanschmutzung und Methoden” des Normenausschusses NA Med 063-04-09 entsprechend
ISO 15883-1 und ISO/TS 15883-5 zugrunde gelegt und mit neuen Komponenten erweitert.
Insgesamt haben sich 7 Laboratorien an den Untersuchungen zur Etablierung dieses Modells beteiligt und im Rahmen von Ringversuchen vergleichende Studienergebnisse eingebracht.
Es werden die aktuellen Ergebnisse vorgestellt, die den Vergleich von unterschiedlichen Reinigern
oder reinigenden Desinfektionsmitteln gegenüber Wasser an mit Fibrin- oder reaktivierten BlutPrüfkörpern aus Glas oder Edelstahl, nach visueller Kontrolle bzw. chemischer Proteinanalytik mittels
OPA oder BCA erlauben.
Diese Ergebnisse dokumentieren aus Sicht des AKR einen Meilenstein auf dem Weg zu einer
validen Einschätzung von Reinigern im Hinblick auf die Entfernung von Blutkontaminationen und
vorherrschendengegebenenfalls proteinfixierenden Eigenschaften.

Diskussion der unterschiedlichen internationalen Akzeptanzkriterien zur Bewertung der
Reinigungswirkung
Discussion of the various international acceptance criteria for the evaluation of cleaning efficacy
Dr. Winfried Michels
Miele & Cie. KG, Gütersloh
Abstract
Reinigung ist die Entfernung von Verschmutzungen unabhängig von der Ausgangsmenge in dem
für seine weitere Behandlung und vorgesehene Verwendung erforderlichen Umfang, d.h. bis zu
einer spezifizierten tolerierbaren Restmenge. Die tolerierbaren Restmengen, da diese nicht auf der
Grundlage klinischer Daten festgelegt werden können und auch die analytische Bestimmungsgrenze nicht maßgeblich ist, müssen anhand der Feststellung des nach dem Stand der Technik gut und
sicher Erreichbaren spezifiziert werden. Da die Technik sich ändert und auch besser wird, müssen die
Festlegungen periodisch überprüft bzw. angepasst werden. Je sauberer ein Medizinprodukt, desto
sicherer die Folgeprozesse nach der Reinigung und die klinische Wiederanwendung am Patienten.
Daher soll stets ein Optimierungsgebot gelten.
Durch Inaugenscheinnahme prüfbare Flächen der Medizinprodukte müssen nach der Reinigung
stets optisch sauber sein, ebenso die gewonnenen Proben für die Analytik. Es sind zusätzlich Beurteilungen, insbesondere der nicht optisch zugänglichen Bereiche der Medizinprodukte, unter Erfassung von chemischen Komponenten bzw. Markern der Anschmutzung nach Probengewinnung und
abhängig von der Risikobeurteilung mit halb-quantitativer oder quantitativer, validierter Methoden
erforderlich. Die Bewertung muss die Größe der geprüften Fläche berücksichtigen, denn nur so ist die
vergleichende Bewertung unterschiedlicher Medizinprodukte möglich. Für die Reinigungsbewertung
müssen die Daten in µg/cm² angegeben werden.
Als analytisch zu erfassende Marker der Reinigung werden bisher gemäß ISO EN 15883 Protein und
Hämoglobin herangezogen, wobei für Hämoglobin bisher nur als qualitative oder halb-quantitative
Methoden Verwendung finden. Da wäre eine quantitative Methode zusätzlich erwünscht. Das FDA
drängt in dem für die Überarbeitung zuständigen Gremium ISO TC 198 WG13 darauf, dass zusätzlich
TOC (Total Organic Carbon) als weiterer Marker in der ISO TS 15883-5 aufgenommen wird und zudem
sind noch Kohlenhydrate sowie ATP in der Diskussion. Diese Marker werden hinsichtlich der Probengewinnung und der Analytik sowie der möglichen Akzeptanzwerte besprochen.

tätig, zuletzt jetzt als medizinisch-hygienische Gesamtleitung.
Abstract
Als unabhängiges, privat geführtes Hygiene-Institut führt die Firma HYBETA u.a. in Gesundheitseinrichtungen Beratungen bei der hygienischen Aufbereitung von Medizinprodukten durch. Gegenwärtig wünschen die Kunden vermehrt nicht nur die Überprüfung der Reinigung mittels Restproteinbestimmung, sondern auch die Validierung ihrer manuellen Aufbereitung. Dieser Wunsch
begründet sich unter anderem durch das Inkrafttreten der Leitlinie der Deutschen Gesellschaft für
Krankenhaushygiene (DGKH), der Deutschen Gesellschaft für Sterilgutversorgung (DGSV) sowie
des Arbeitskreises Instrumentenaufbereitung (AKI) in Kooperation mit dem Verbund für angewandte
Hygiene (VAH) zur Validierung der manuellen Reinigung und manuellen chemischen Desinfektion
von Medizinprodukten in 2013.
Ziel des Vortrags ist es, erste Erfahrungen bei der Umsetzung der Validierung der manuellen
Reinigung und der chemischen Desinfektion in Gesundheitseinrichtungen aus der Sicht der in der
Hygieneberatung tätigen Personen darzustellen, Abläufe bei der Beratung zu beschreiben und die
daraus bisher gezogenen notwendigen Maßnahmen aufzuzeigen.

Abstract
Allein der Begriff der Validierung manueller Aufbereitung birgt Zündstoff. „Manuelle Reinigungs- und
Desinfektionsverfahren“ sind nach obergerichtlicher Rechtsprechung „regelmäßig nicht validierbar“.
Regeln haben mitunter Ausnahmen; auch dies entspricht in engen Grenzen der hier angefragten
juristischen Akzeptanz. Prüfgegenstand in diesem Zusammenhang ist die aktuelle Leitlinie zur Vali-
page 106
dierung der manuellen Reinigung und manuellen chemischen Desinfektion von Medizinprodukten.
Es ist schon richtungsweisend, dass die erwähnte Leitlinie von DGKH, DGSV, AKI in Kooperation mit
dem VAH die manuelle Aufbereitung von „kritisch B-Produkten“ und aufwärts ausschließt, zumal zu
dem Spektrum dieser Leitlinie eine entgegenstehende gefestigte Rechtsprechung nicht vorliegt.
Gehen wir zunächst davon aus, dass eine leitlinienkonforme Aufbereitung grundsätzlich in einem
näher zu definierendem Rahmen rechtlich zulässig sein kann, gilt es, entsprechend dem Umsetzungsversuch dieser Leitlinie die exakte Reproduzierbarkeit der Aufbereitungsprozesse einschließlich der Prüfergebnisse dokumentarisch nachzuweisen. Dies entspricht der im MPG verpflichtend
gesetzten Vorgabe, bei der Aufbereitung von Medizinprodukten alle erforderlichen Maßnahmen
zum Schutze der Gesundheit und zur Sicherheit von Patienten, Anwendern und Dritten vor Gefahren
durch Medizinprodukte zu treffen.
Dabei soll nicht unerwähnt bleiben: die zu recht von der Rechtsprechung sehr hoch gestellten
Anforderungen an eine Validierung bei grundsätzlich nicht als ausreichend angesehener Standardisierung lässt offen, ob ein quasi-Verbot der manuellen Aufbereitung von kritisch B-Produkten
nicht zukünftig umfassend erweitert wird. Bislang bestand hierzu mangels gerichtlicher Vorlage kein
Anlass, wobei Gerichte keine Fragen entscheiden, die bislang nicht prozessrelevant geworden sind.
Die Prognose hierzu ist ungewiss - vor Gericht und auf hoher See sind wir in Gottes Hand.

Revision of ISO 17664: product groups and other issues - what can we expect?
In 1991 after having studying engineering and after the vocational education as a dental technician,
I joined the working group of Professor Buess in Tuebingen. From the beginning I was involved in
the development and designing of instruments for minimally invasive surgery. One of the main
tasks beside the functionality was the reprocessing of the long and complex devices with narrow
lumens. Several test methods have been developed, which allow a localisation and quantification of
remaining contamination inside the devices to assess the cleaning behaviour. These test methods
have been the basis for three cooperative research projects to improve the cleaning behaviour of
surgical devices. The projects have been funded by the state of Baden- Wuerttemberg. In 2000, I
founded SMP GmbH, a company that concentrates on applying the test methods, in particular the
radionuclide method, which can be used to validate the cleaning behaviour of medical products.
SMP GmbH is also specialized in the sterilizability of medical products with moist heat or hydrogen
peroxide plasma (ASP Johnson & Johnson method) and services for evaluating prion decontamination on surgical instruments.

Abstract
Die Typprüfung eines Reinigungs-Desinfektionsgerätes für thermolabile Endoskope (RDG-E) liegt im
Verantwortungsbereich des RDG-E-Herstellers. Sie ist die Grundlage für die Bewertung der Risiken
bei der maschinellen Aufbereitung thermolabiler Endoskope und dient dem Nachweis der Übereinstimmung eines RDG-E mit den Anforderungen der DIN EN ISO 15883-1 (1) und -4 (2) unter Anwendung von Methoden aus der DIN ISO/TS 15883-5 (3).
Die Markterfahrung in den ersten Jahren nach Einführung der EN ISO 15883-4 zeigt, dass bei der
Durchführung von Typprüfungen für RDG-E relevante Differenzen auftreten hinsichtlich:
• Art und Umfang der Prüfungen
• Einbeziehung repräsentativer Endoskope unterschiedlicher Hersteller
Dies resultiert maßgeblich aus der Tatsache, dass ein Spannungsfeld unterschiedlicher Interessen
und Abhängigkeiten vorliegt:
• Einerseits das Interesse des RDG-E Herstellers, der in der Typprüfung auf Angaben der Endoskop- und Prozesschemikalien-Hersteller angewiesen ist, und den Umfang der Prüfungen auf ein
notwendiges Minimum reduzieren will
• Andererseits das Interesse der RDG-E-Betreiber, der durch die Typprüfung ein hohes Maß an
Sicherheit für die beim ihm eingesetzten Endoskope und Prozesschemikalien nachgewiesen
haben möchte.
Darüber hinaus gestaltet sich das relevante Normenwerk sehr komplex und lässt großen Interpretationsspielraum zu – sowohl für Hersteller als auch für benannte Prüfstellen und Behörden.
Vor diesem Hintergrund ist es erforderlich, im Sinne aller Beteiligten den notwendigen Umfang der
Typprüfung zu definieren, der alle relevanten Aspekte der Patientensicherheit berücksichtigt und den
Umfang der Testungen auf ein praktikables Ausmaß begrenzt.
Hierzu wurde im Rahmen der Erarbeitung der „Leitlinie zur Validierung maschineller ReinigungsDesinfektionsprozesse zur Aufbereitung thermolabiler Endoskope“ eine Arbeitsgruppe aus Experten
von Herstellern von RDG-E, von Endoskopen und von Prozesschemikalien unter Koordination des
Arbeitskreises für Instrumentenaufbereitung (AKI) gebildet.
Im Rahmen des Vortrages werden die Ergebnisse der Arbeitsgruppe hinsichtlich der durchzuführende Testungen
- zur Überprüfung der konstruktiven Merkmale des Reinigungs-Desinfektionsgerätes,
- zu Prüfungen der Prozesschemie,
- zu Leistungstests des Reinigungs-Desinfektionsgerätes in Kombination mit Prozesschemie und
- zu Leistungstests des Reinigungs-Desinfektionsgerätes in Kombination mit Prozesschemie und
Endoskopen
vorgestellt und spezifische Anforderungen für den Vertrieb in Deutschland diskutiert.

Abstract
Obwohl die Reinigung mit Ultraschall in flüssigen Medien seit vielen Jahrzehnten ein bekanntes und
oft verwendetes Verfahren darstellt, sind die genauen mikroskopischen Mechanismen sowie deren
Kontrolle noch nicht vollständig verstanden. Im Vortrag sollen die physikalischen Vorgänge bei der
Abreinigung fester Oberflächen näher beleuchtet werden. Es wird gezeigt, dass Kavitationsblasen
und deren Wechselwirkung mit Grenzflächen die entscheidende Rolle spielen, und das “geheime”
Leben dieser Blasen wird zugänglich gemacht durch mikroskopische Hochgeschwindigkeitsaufnahmen und theoretische Betrachtungen. Des weiteren werden die Entkeimung durch Kavitation sowie
Versuche zur Normung angesprochen.
Plasmasterilisation: Funktionsweise und Anwendungsgebiete

Abstract
Die Sterilität medizinischer Objekte ist eine wichtige Voraussetzung, um die Sicherheit von Patienten
und Personal zu gewährleisten. In der Praxis bedeutet das einen hohen Aufwand für die hygienische
Aufbereitung von wiederverwendbaren Materialien, sowie eine Herausforderung für die sterile Lagerung. Viele der etablierten Sterilisationsmethoden beinhalten diverse Nachteile, wie zum Beispiel
lange Prozesszeiten bei hohen Temperaturen. Hinzu kommen Unzulänglichkeiten in Bezug auf die
Protein- und Prionenentfernung.
Ein erfolgversprechender Ansatz für eine neue Sterilisationsmethode ist die Plasmasterilisation.
Vorteile der Plasmasterilisation sind kurze Prozesszeiten bei niedrigen Temperaturen, sowie die
Wirksamkeit gegen Bakterien, bakterielle Sporen, Proteine und Prionen [1]. Der weltweit erste Plasmasterilisator findet Anwendung in der Sterilisation pharmazeutischer Produkte [2], während sich
ein Desktop-Sterilisator zur Sterilisation medizinischer Instrumente noch in der Entwicklung befindet
[3]. Die Funktionsweise der Plasmasterilisation wird anhand der beiden Sterilisatoren erläutert, sowie
Sterilisationsergebnisse und mögliche Anwendungsgebiete vorgestellt.

Abstract
Die Entwicklung von Implantaten fokussiert in immer weiteren Bereichen die Verwendung von
synthetischen resorbierbaren Biomaterialien. Hierdurch kann beispielsweise die konventionelle
Verwendung von Spenderknochenmaterial reduziert und die Infektionsgefahr gesenkt werden.
Resorbierbare (nichtmetallische) Materialien sind jedoch thermolabil und häufig auch empfindlich
gegenüber etablierten Niedertemperatur-(NT)-Sterilisationsverfahren wie z.B. EO, Gamma, NTDF, da
sich die Stabilität und die zelluläre Besiedlungsfähigkeit verändern. Daher besteht ein dringender
Bedarf nach der synergistischen Entwicklung von innovativen Implantatmaterialien mit optimierten
Porenstrukturen und geeigneten NT-Sterilisationsverfahren, die für den späteren klinischen Einsatz
eine Sterilisation ermöglichen.
Im Rahmen eines gemeinsamen Forschungsprojekts entwickelte die Technische Universität
Dresden unter der Leitung von Prof. Gelinsky neue optimierte Implantmaterialien. Am wfk wurden
neue geeignete NT-Sterilisationsverfahren auf der Basis von überkritischem Kohlendioxid (SCCO2)
entwickelt.
Es wurden drei unterschiedliche SCCO2-Prozesse (M1, M2, M3) etabliert, die eine Behandlung empfindlicher Implantatmaterialien bei 38 °C und 8,5 MPa (85 bar) ermöglichen. Im Rahmen der Entwicklungsarbeiten wurden unterschiedliche Prüfkörpermodelle etabliert, das phylogenetische Wirkspektrum untersucht, geeignete Prüfmikroorganismen ermittelt und ein geeignetes Sterilgutbarrieresystem
festgelegt. Die drei Verfahren wurden ausgiebig charakterisiert und die jeweiligen D-Werte bestimmt.

Methoden zur Evaluierung von Prozesschemikalienrückständen bei der Leistungsqualifikation
Methods to assess process chemical residues during the performance qualification
Dr. Matthias Tschoerner
Chemische Fabrik Dr. Weigert GmbH & Co. KG, Hamburg
Abstract
Bei einer ordnungsgemäßen Aufbereitung von Medizinprodukten dürfen nach Abschluss der Reinigung und Desinfektion von den eingesetzten Prozesschemikalien nur toxikologisch unbedenkliche
Restmengen auf den Oberflächen verbleiben, welche eine Gefährdung von Patient, Anwender und
Dritten sicher ausschließen. Dafür müssen tolerierbare Werte festgelegt und geeignete Methoden
zur Verfügung stehen, die es ermöglichen, die Einhaltung dieser Grenzwerte nachzuweisen.
Für die Validierung der maschinellen Aufbereitung von semikritischen und kritischen Medizinprodukten werden von den Herstellern der Prozesschemikalien Grenzwerte für die maximal tolerierbaren
Prozesschemikalienrückstände festgelegt und Methoden zur Überprüfung der Einhaltung angegeben. Im Rahmen der Leistungsqualifikation nach der DIN EN ISO 15883 ist bei der Prüfung der
Wirksamkeit des Spülprozesses die Einhaltung der Grenzwerte für die maximal tolerierbaren Prozesschemikalienrückstände nachzuweisen. Für die manuelle Aufbereitung sind hierfür bisher wenige
Informationen verfügbar. Daher wurden verschiedene Methoden zur praxisgerechten Bestimmung
der nach der manuellen Aufbereitung auf chirurgischen Instrumenten verbliebenen Prozesschemikalienrückstände von einer Arbeitsgruppe des IHO entwickelt und an verschiedenen Gruppen von
Reinigungs- und Desinfektionsmitteln geprüft (Desinfektionsmittel mit Glutaraldehyd; Desinfektionsmittel mit Peressigsäure; Desinfektions- und Reinigungsmittel mit quartären Ammonium-Verbindungen und Aminen; Mildalkalisches Reinigungsmittel mit Tensiden und Enzymen). Die erarbeiteten
Methodenvorschläge zur Bestimmung der auf den Medizinprodukten verbliebenen Prozesschemikalienrückstände nach der Aufbereitung und die damit erzielten Ergebnisse werden hier vorgestellt.

Dr. Amelie P. Houben studierte Biologie an der Heinrich-Heine-Universität Düsseldorf. Anfang 2012
beendete sie erfolgreich ihre Dissertation am Institut für Transplantationsdiagnostik und Zelltherapeutika. Seitdem ist sie beim wfk-Institut im Bereich Hygiene und Mikrobiologie beschäftigt. Sie
bearbeitete verschiedene Projekte auf dem Gebiet der Hygiene, mit dem Schwerpunkt Reinigung,
Desinfektion und Sterilisation von Medizinprodukten sowie Prozesskontrollen.
Abstract
Die Aufbereitung von wiederverwendbaren medizinischen Instrumenten wie z.B. flexiblen Endoskopen muss die gesetzlichen und normativen Anforderungen erfüllen, um die Übertragung von
Infektionserregern zu verhindern und die Sicherheit für Patienten und Klinikpersonal zu gewährleisten. Flexible Endoskope sind thermolabil, verfügen über extrem komplexe Geometrien mit langen
internen Kanalsystemen und erfordern spezielle Verfahren bei der maschinellen Aufbereitung.
Die im Herbst 2011 erstmals publizierte „Leitlinie zur Validierung maschineller Reinigungs-Desinfektionsprozesse zur Aufbereitung thermolabiler Endoskope“ umfasst in Anlage 9 das aus ISO/TS
15883-5, Anhang I, abgeleitete Prüfkörpermodell zur Bestimmung der Gesamtprozessleistung. Diese
Schlauch-Prüfkörper stellen einen Bezug zur Geometrie des Kanalsystems flexibler Endoskope her
und werden für die Bewertung und Quantifizierung der Wirksamkeit des Aufbereitungsprozesses
verwendet. Die Auswertung der Ergebnisse beim Einsatz von konventionellen Prüfkörpern setzt ein
mikrobiologisches Labor voraus und liegt erst nach mehreren Tagen vor. Eine einfache und schnelle
Methode zur innerbetrieblichen Kontrolle der Gesamtprozesswirkung ohne Verwendung von
Prüforganismen und klassischen mikrobiologischen Methoden ist nicht verfügbar. Im Rahmen des
Projektes wurde ein enzymatischer Prüfkörper zur Routineprüfung der Gesamtprozessleistung bei
der Aufbereitung thermolabiler Medizinprodukte in sogenannten Reinigungs-Desinfektionsgeräten
für Endoskope (RDG-E) entwickelt, der im Rahmen der innerbetrieblichen Eigenkontrolle angewandt
werden kann.
Der enzymatische Prüfkörper basiert auf dem Einsatz von Enzymen als Surrogatmodell für die
konventionell verwendeten Mikroorganismen (Enterococcus faecium). Es konnte eine reproduzierbare, enzymstabilisierende Fibrinanschmutzungen als Immobilisierungsmatrix für die Enzyme in
Schlauchelementen etabliert werden. Ebenso konnte die Prüfkörperintegration in verschiedenen
Maschinentypen (Druckkammer oder Einzelkanalanschluss) realisiert werden. Funktionsmuster der
Enzymprüfkörper zeigten sowohl im Labor als auch in der Praxis eine gute Übereinstimmung mit
Prüfkörpern gemäß Anlage 8 und 9 der o.g. Leitlinie. Die Verwendung von Substraten mit farbigen
Produkten ermöglicht die visuelle Evaluierung der Wirksamkeit der Aufbereitungsverfahren. Auch
ohne externes Fachpersonal ist eine Beurteilung der Gesamtprozessleistung so innerhalb von ca. 10
Minuten möglich.

Medizinprodukteaufbereitung - Validierung der involvierten Prozesse - Wo stehen wir?
Medical device reprocessing - Validation of applied processes - where have we got?
Dr. Thomas W. Fengler
Cleanical GmbH, Berlin
Abstract
Eine Validierung ist laut DIN EN ISO 17665-1:2006 ein „dokumentiertes Verfahren zum Erbringen,
Aufzeichnen und Interpretieren der Ergebnisse, die für den Nachweis benötigt werden, dass ein
Verfahren beständig Produkte liefert, die den vorgegebenen Spezifikationen entsprechen“ . Die
Verifizierung und Kontrolle der bei der Aufbereitung von Medizinprodukten zum Einsatz kommenden, nur teilweise automatisierten Prozesse obliegt dem Betreiber, diese wird bei den gesetzlich
vorgeschriebenen Validierungen überprüft und regelmäßig einer erneuten Leistungsqualifikation
unterzogen. Beim Studium der Validierungsleitlinien von Prozessen (z.B. im RDG-E) wird deutlich, wo
das Problem liegt: Zuviel ist nicht genug!
Neben inhaltlichen Voraussetzungen kommen verschiedene, zu diskutierende Prüfinstrumente und
Prüfszenarien zur Anwendung, ein Ergebnis wird in einem möglichst strukturierten Protokoll dokumentiert. Die Leitlinien sollen hier die nötigen Handlungshinweise für den Validierer geben, der über
ausreichendes Wissen und Erfahrungen mit den Verfahren und der Validierung verfügen muss. Sie
stellen aber in Bezug auf die Hygiene nur eine Übereinkunft (Konvention) dar.
Das bedeutet, die Nichterfüllung der so genannten « Akzeptanzkriterien» geht nicht automatisch mit
Infektion und Funktionsverlust der Medizinprodukte einher, um einmal die wichtigsten Zielgrößen
in unserem Qualitätsmanagement zu nennen. Sie gibt dem Betreiber aber wichtige Hinweise hinsichtlich der Qualität seines Prozesses, so dass er geeignete Maßnahmen ergreifen kann, wovon die
Stilllegung eines Gerätes sicherlich nicht die erste ist. Oftmals geht es dabei um die Wasserqualität
und dementsprechend um engmaschigere Kontrollen, bis das Problem behoben ist («event-related»
d.h. «Ereignis-bezogen»).
Alle derzeitigen Prüfkörpermodelle und Medizinproduktesimulatoren weisen Stärken und Schwächen auf und erschweren insbesondere einen Vergleich untereinander. Die Validierung bleibt damit
eine Überprüfung unter speziellen Bedingungen, der die alltägliche Verifikation des Aufbereiters
gegenübersteht. Die Aufbereitungsleistung kann also immer nur in Teilaspekten möglichst dicht an
den tatsächlichen Arbeitsverhältnissen überprüft werden.
Der Vortrag behandelt u.a. folgende Teilaspekte des Themas:
•
Einflussfaktoren der Aufbereitung
•
„Leid und Leid-Linien“: Wie ist die klinische Situation?
•
Validierung und Verifikation zählbarer und nicht-zählbarer Ereignisse
•
Vorbereitung, Durchführung und Auswertung der Prozessvalidierung

Abstract
The role of the environment is often ignored in the spreading of nosocomial infections as person-to-person transmission route is the most common vehicle for transmission. However, it is also
possible for hospital linen to be a vehicle for transmission. The following test microorganisms at
different concentrations were inoculated onto textile swatches and dried overnight: Staphylococcus
aureus The following test microorganisms at different concentrations were inoculated onto textile
swatches and dried overnight: Staphylococcus aureus, Klebsiella pneumoniae and Pseudomonas
aeruginosa. RODAC plate sampling as well as a non-destructive wash-off method for capturing
microorganisms from the textiles using a Morapex device was used. All chosen bacteria were found
using all methods. However, the wash-off method using the Morapex device yielded results in a
wider concentration range. The final detectable recovered bacterial concentration on textiles was up
to 10 cfu/mL.

Abstract
Although person-to-person transmission is the most likely route for healthcare associated infections,
the role of the environment should not be ignored and may also contribute to the spread of nosocomial infections. It has been proven that microorganisms are able to survive on environmental surfaces up to several weeks, therefore providing a potential for biotransfer. Assessment of environmental
cleanliness is mainly conducted by surface sampling and swabbing, which is followed by classical
incubation methods based on phenotypic detection of microorganisms. These methods take between 2 to 4 days. Novel quick methods based on DNA detection using PCR methods is a possibility
for quick detection of the presence of DNA. In the present study, we investigated the presence of
the following challenge microorganisms: Enterococcus faecium, Staphylococcus aureus, Bacillus

Abstract
The Xeros laundry washing system uses specially-designed polymer beads in place of large
amounts of hot water to remove stains from fabrics. These polymer beads efficiently extract stains
from fabrics and, as water is no longer the primary means of removing stains, the Xeros system can
get fabrics clean while using significantly lower temperatures with less water and detergent than a
standard commercial laundry machine. The current design and size of the Xeros beads are a direct
result of years of research by the Xeros R&D team. In testing various bead compositions, sizes, and
designs, it was found that several factors affected the cleaning performance of the beads. Not only
do Xeros beads last for hundreds of uses, they are completely recyclable as well. The polymers used
in the Xeros beads are suitable for several applications, such as the manufacture of plastic parts for
automobiles.

Abstract
An Automated process for hard surface care consists of an alternating rinse, clean and care cycle.
The project consists of the following building blocks:
- Realisation of a dynamic dosage concept at a washing and spinning machine
- Formulation of possible care, cleaning and preservative products for interval use
- Long-term observation of cleaning quality - simulation at the linear wipe test stand as well as
accompanying environment simulation test on surfaces
- Statistical data interpretation, determination of cause and effect as well as efficiency test
Over a testing phase of one year, the newly developed dynamic dosage method was compared to
the established fixed dosage/one product procedures. These are the results:
- The dynamic dosage was able to reduce the average detergent usage by around 30 to 50 percent, while no significantly poorer cleaning results were detected at the linear wiping stand. (The
page 118
-
test was conducted following the IKW method, using anorganic as well as fatty test soils.)
Dynamic dosages lead to less significant changes in floor properties than fixed dosages. The
parameters compared with each other would be sure all the netting property, the degree of gloss
as well as the friction of the floors.

Abstract
Bacterial subtilisins are the subgroup of serine proteases of major industrial significance and have
been studied extensively. Due to their large scale production and outstanding properties subtilisins
have a leading application in laundry detergents. As one of the key ingredients subtilisins need to
meet requirements defined by manufacturers in order to boost cleaning performance of laundry
detergents. The development of subtilisins with an emphasis on improved performance/cost ratios,
increased activity and improved compatibility with other detergent ingredients are the main focus
in the recent years. Directed protease evolution as a tool for subtilisins engineering showed an signif-

Abstract
Following current consumer habits, laundry detergents should maintain high levels of hygienic
performance even at lower washing temperatures. We investigated the antimicrobial efficacy of a
solid laundry detergent formulation at 20 °C and 40 °C using a small-scale (250 ml) in-vitro procedure, a mid-scale (500 ml) procedure involving a Linitest laboratory washing machine (Atlas MTT,
Linsengericht, Germany), commonly used for staining/destaining experiments, and a large scale (45
l) procedure using domestic washing machines, respectively. To the best of our knowledge, the Linitest washer was used here for the first time for antimicrobial efficacy testing of laundry detergents.
Washing tests followed VAH guidelines and were performed with microbially contaminated cotton
carriers washed together with sterile ballast fabrics. Germ reduction rates served as quantitative
mean to evaluate the hygienic performance.
At 40 °C, all microorganisms were reduced by >4 lg-scales in all experiments. At 20 °C, the reduction
of gram-negative bacteria and of C. albicans was lower, but still >3.5 lg-scales, when experiments
were performed in large scale. The better antimicrobial efficacy at higher temperature is probably
due to more effective activation of bleach components. Germ reduction was similar among the three
investigated washing methods. However, small and mid scale experiments slightly underestimated
the antimicrobial efficacy compared to the large scale washing procedure. Nevertheless, the Linitest
washer proved to be an attractive new screening tool to evaluate the hygienic performance of laundry detergents.

Renewable functionalization of laminated textiles to optimize the water vapor permeability
Erneuerbare Funktionalisierung von Textillaminaten zur Optimierung der
Wasserdampfdurchlässigkeit

Abstract
High performance protective clothing (e.g. weatherproof or firefighter’s clothing) faces high functional demands regarding its water repellency and also increasingly its wearing comfort. Therefore
textile laminates containing a breathable (water vapor permeable) membrane are commonly used.
The surface layer is coated with a hydrophobic fluorocarbon (FC)-resin while the inner lining is more
hydrophilic to achieve a fast and effective transport of perspiration towards the water permeable
membrane.
The FC-layer can be damaged or outworn during regular use due to friction and other mechanical
impact. Additionally the water repellent properties can diminish by washing. Thus textile service
companies perform a hydrophobic regeneration step by application of new FC-polymers after each
washing circle to maintain the water repellency. The currently used method for the rehydrophobization in an immersion bath leads to a deposition of the FC-polymers on both, the hydrophobic surface
and the inner lining. Accordingly the transport of perspiration through the inner layer towards the
membrane is decreasing or even inhibited with an increasing number of reconditioning steps.
One approach to obtain a selective rehydrophobization of the outer shell of the laminar material is
the simultaneous application of FC-polymers with a pH-switchable anionic polymer as a selective
and temporary protective coating for the inner lining. The pH-switchable anionic polymers with
tailored hydrophobicity can be applied to the inner linings by a competitive displacement of the
FC-polymers during the hydrophobic reconditioning at a pH-level of 4-6. The deposition of FC-polymers on the hydrophobic surface layer is not affected by the simultaneous application since the
pH-switchable polymer doesn’t interact with the hydrophobic layer. Thus only the FC-resin deposits
on the hydrophobic surface. In a subsequent washing step under alkaline conditions the interaction
and therefore the adhesion between the pH-switchable polymer and the lining decreases. In consequence the polymer can be removed entirely from the inner linings of the textile laminates.
Therefore the functional properties of the textile laminates can be preserved, which allows an increased number of usage and processing cycles of the high-value textiles.

Cleaning and care of elastic flooring is an important market segment for cleaning companies. Elastic
floorings usually have temporary coatings to protect them from scratches, abrasion or to improve
their cleaning properties. At longer contact times, some soil components can migrate through the

applied polymeric coatings into the top layer of the floorings itself and cause a permanent damage
of the flooring material. Examples for such problematic soils are particularly alcoholic disinfectant,
iodine-containing ointments as well as substances in medical, beauty and wellness products.
Furthermore, discolorations can also be caused by exposition to plasticizers between dark colored
furniture gliders, car tires, bicycle tires.
Within the project the barrier function of floorcare coatings against soil components will be improved
by developing a bilayer floorcare coating for elastic flooring, which has a high resistance to conventional soils. The developed two-layer systems consist of a cationic polymer layer with included
anionic adsorbers and a waxy, anionic polymer layer as top layer.
The cationic polymer layer is able to immobilize anionic soil components via electrostatic interactions. Accordingly the anionic adsorbent is able to fix cationic soil components by electrostatic interactions within the network. Therefore a migration towards the elastic floorings is prevented. Furthermore a higher degree of crosslinking in the polymeric coatings is achieved by the addition of anionic
adsorbent to the cationic polymer dispersion, resulting in a better resistance to damaging through
soil components. With increasing degree of crosslinking, the diffusivity of soil components is lower
and the barrier effect increases. Additionally, the electrostatic binding of anionic soil components on
the surface of the film coating is prevented by the uppermost waxy and anionic polymer layer. By
selection of suitable waxes, it is possible to optimize the surface properties and the resistance of the
film coating against soil components.

Abstract
In hygienically demanding areas hygiene quality management (QM) systems are of great importance
due to constantly increasing hygienic requirements. For analysis of the cleaning and disinfection
measures, determined by QM-systems, random checks are carried out routinely. Currently, contact
plates are used for the sampling of surfaces. After sampling, the contact plates must be incubated
and analyzed by external microbiological laboratories. The process time requires at least 3 days
(determination of total germ count and hygienic relevant microorganisms) and results in high costs.
Moreover, probably necessary corrective measures of cleaning and disinfection might only be
performed delayed due to the long analysis period. Therefore, there is a strong need of innovative
methods for the real-time determination of both hygienic relevant microorganisms and total germ
count on surfaces within a self-regulation.
The aim of the project is the development of a method for sampling surfaces on the basis of lectine
functionalized thermosensitive polymer brushes. The lectine functionalized polymer brushes are
page 122
used to sample microorganisms from surfaces similar to a contact plate. The flexible chains of
polymer brushes are able to penetrate cavities of structured surfaces and therefore sample surfaces
more effectively. The thermosensitivity of the polymer brushes can be used for sampling very
structured surfaces so that the chains of used polymer brushes do not interrupt during removal from
the surface. Due to a short temperature stimulus the chains shorten and compress towards brush
substrate and remove the microorganisms from the surface. For visualization and quantification
of bound microorganisms the polymer brush will be incubated with fluorescent Quantum Dots.
Depending on the application the Quantum Dots are functionalized with antibodies or lectines. This
method allows both the determination of hygienic relevant microorganisms (antibody functionalized
Quantum Dots) and of all microorganisms (lectine functionalized Quantum Dots) on the same sample within approximately two hours.

Abstract
Elastic floorings commonly are finished by a temporary coating based on polymers to achieve optimim cleaning conditions. The coating minimizes soil adhesion to the flooring surface. After extended
wear periods - especially under conditions with extensive mechanical wear - the coating is stripped
with chemicals (alkaline cleaners) followed by a re-coating process to renew the optical appearance
and to minimize wearing effects. The stripping process shows significant disadvantages like long
drying time prior the following re-coating, high labour effort and high consumption values of water
and chemicals. Pre-tests of wfk showed that the application of a dry basic stripping process by use
of non-thermal atmospheric pressure plasma is able to resolve these disadvantages.
Aim of the research project is the development of a water-free basic stripping process based on the
use of atmospheric plasma. This process needs no drying procedure before re-coating. Consequence is a significant increase of the flooring area coverage of the maintenance cleaner because
of minimized delays in the operating sequences. Therefore, in the first step renewable plasma
active coatings are developed, which show both strong adhesion on the flooring and are easily
removed by plasma processing. The coatings are developed in a two-layer process. The lower layer
(intumescence layer) shall absorb the plasma energy heat. This layer, in combination with an on top
positioned heat-conducting layer will be blasted during the plasma treatment. Further investigations
focus on the integration of plasma active intumescence layers into the covering of future generations of floorings by flooring’s producer. Finally, a prototype of a dry plasma based de-coating
device will be developed, which is tested and optimized under practice conditions. The presented
poster summarizes first results of this research project.

technologies for textiles as well as hard surfaces.
Abstract
Textile service companies often face the challenge to meet two contrary requirements: On the one
hand due to customer demands, legislation, and standards they have to guarantee and document
the quality of the processed textiles with respect to different parameters (e. g. hygiene, protective
function). This leads to increasing requirements on the quality of the used process waters, especially
during the rinsing phase. On the other hand due to economic reasons process waters are increasingly reused.
A possible solution is the photocatalytic treatment of weakly contaminated process waters with
novel TiO2 catalysts based on ferrimagnetic core shell microparticles with a multi-layer structure.
Compared to the currently used photocatalytic systems they have several decisive advantages:
• High photocatalytic activity due to a large catalyst surface; the electrostatic repulsion of the
charged catalyst particles prevents agglomeration of the suspended particles
•
Easy particle recovery by magnetic separation: the ferrimagnetic properties of the catalysts allow
an easy and efficient separation from the aqueous phase after photocatalytic treatment
• High mechanical stability by embedding the TiO2 particles into alternating positive and negative
elastic poly-electrolyte layers
This approach is investigated by wfk within an ongoing research project.

Abstract
Timely monitoring and documentation of cleaning and disinfection processes is indispensable in
hygienically demanding areas due to constantly increasing hygienic requirements. Complete wetting
of the entire treated surface is imperative for adequate disinfection and soil removal in cleaning and
disinfection processes. At present, surface wetting of elastic floorings cannot be retraced during wiping process. For analysis of cleaning and disinfection measures random checks using contact plates
are carried out routinely. Sampling is only on a random basis and contact plates must be incubated
and analysed by external microbiological laboratories after sampling which takes at least two days
and results in high costs. Probably necessary corrective measures of cleaning and disinfection might
only be performed delayed due to the long analysis period.
One approach to control surface wetting in cleaning and disinfection processes is the development
of optochemical care coatings which are colorless and transparent in dry state, whereas in contact
with cleaning and disinfectant solutions they exhibit a distinct reversible color change. Optochemical
care coatings are obtained through inclusion of core-shell latex particles in conventional care coatings. Such core-shell latex particles consist of a hydrophobic polymer core coated with a hydrophilic
polymer shell. Refractive indices of core and shell are almost equal in dry state, therefore, no light
scattering occurs in a latex layer and it is transparent and colorless. At contact of a core-shell latex
particle with a polar solvent (e.g. water in cleaning and disinfectant solutions), solvent is incorporated
exclusively into the hydrophilic shell resulting in a refractive index difference between core and shell.
Therefore, light is scattered by latex layer and layer becomes coloured. Colour of core-shell latex
particles and thus of optochemical care coatings in wetted state can be chosen by size of core-shell
latex particles providing high contrast to coated elastic floorings.
Surface wetting can be retraced visually by using optochemical care coatings and thus application
of sufficient amounts of cleaning and disinfectant solutions on the entire treated area during wiping
process can be ensured.

comply with certain hygiene requirements. Process waters have to meet the microbial acceptance
levels of the Drinking Water Ordinance, i.e. the overall number of non-pathogenic bacteria must not
exceed 100 cells per ml, relevant indicator microorganisms like Escherichia coli, coliform bacteria and
enterococci must not be present in 100 ml of water. The analysis of water samples applying classical
microbiological methods requires at least two days and is usually carried out by external microbiological laboratories. Rapid tests for microbial contaminations that give reliable results, that are easy
to apply and that are inexpensive are not available up to date. Within the research project a quick and
easy-to-use test is being developed that will allow the quantitative analysis of the overall microbial
content as well as the content of relevant indicator organisms (E. coli, coliform bacteria, enterococci).
The test is based on the species specific and non-specific binding of bacterial cells to quantum
dots and their immobilization to a carrier system. Within the project quantum dots were characterized
regarding their characteristic fluorescence properties. The quantum dots were functionalized so that
they will bind non-specifically to all bacterial cells or specifically to relevant indicator microorganisms.
According to literature the binding of viable bacteria to quantum dots can lead to a hypsochromic
effect, which can be used to quantify the number of living bacterial cells. This hypsochromic effect,
however, could not be reproduced within this project. Hence, alternatives, which allow a live/dead
discrimination based on quantum dot binding, are currently investigated. Aim of the new rapid-test is
to give results on the hygiene status of process waters within 2 hours.

Abstract
Within the project surgical textiles with improved physiological properties while maintaining the
performance characteristics referring to DIN EN 13795 (Hohenstein Institute) and an adapted
reprocessing method with reduced thermal and mechanical textile impact (wfk) are developed. The
reprocessing method is based on preactivated disinfectant systems in combination with special enzymes in order to preserve optimum textile technological and physiological functions and to ensure
a long lifetime of textiles. For this purpose temperature dependent storage stability of preactivated
disinfectant systems and enzymes was determined. Furthermore soil removal and disinfectant
effect of selected systems were characterized. Determination of temperature dependent disinfectant
effect was carried out using LIVE/DEAD® BacLight™ Bacterial Viability Kit. These outcomes were
compared with suspension tests based on DIN EN 1276. Based on this results preactivated disinfectant systems and special enzymes are chosen and integrated into a treatment process with reduced
thermal and mechanical parameters.

(University of Leipzig) at the turn of the year 2013/2014. Since 2014, he is working as a project leader
at wfk.
Abstract
Aerosols comprised of ink and moistening agents are deposited everywhere inside printing machines during printing processes. The importance of clean rubber rollers and printing cylinders is
obvious. However, also soils on machine housings endanger the maintenance of steady printing
quality. Any kind of ink-soils in the machine may cause misprints, due to undesired spreading of ink.
In order to avoid such misprints additional non-operation periods for cleaning need to be considered.
This would decrease time and cost effectiveness of the printing process. Moreover, massive and
hard to clean colour stains also reduce the resale value of the printing machines.
Currently, organic solvents are applied in order to remove these predominantly oil-based printing
inks. The use of toxic organic solvents increases process costs significantly (high purchase and disposal costs). Furthermore, it requires considerable measures to assure labour protection. No attempts
to avoid these strongly adhesive ink-soils in the devices (e.g. extraction systems, self-cleaning
coatings, etc.) lead to the desired effect so far. Assignment of external cleaning companies with the
cleaning of printing machines becomes more and more attractive for printing shops, and opens a
wide substantial market potential for the cleaning service industry. Therefore, the development of an
economic process with the possibility of environmentally friendly cleaning of printing machines is an
essential requirement.
The wfk-institute and the Fogra Institute e.V. are developing an alternative cleaning procedure based
on coatings of amphiphilic and microporous polymer films. Due to their high hydrophobic and easily
swellable character, these coatings prevent the adhesion of ink on the inner surface of printing machines and enable an efficient and economic cleaning with water. The replacement of toxic organic
solvents by water is a crucial advantage of this new cleaning process.

Abstract
Elderly and nursing home outerwear is often strongly affected by hydrophilic soil such as excretions,
food components or sweat. Due to the nature of the soils it can be expected that the outerwear is
additionally contaminated with microorganisms. Preliminary wfk investigations showed that radial
shock waves can be used as a principal solution for gentle textile processing under optimized wet
cleaning conditions in cold water.
Therefore, the target of the demonstrated project is the development of effective, sustainable,
hygienic and gentle reprocessing methods for sensitive outerwear based on radial shock waves. For
this, at first a cleaning device for shock wave generation is built and the occurring pressure and flow
profiles at and through textiles in aqueous media are identified in order to determine a maximum textile treatment area. This is followed by experimental investigations concerning cleaning effect, reduction of microorganisms and the effect of shock waves on textile properties. Based on this, the shock
wave application is optimized for three-dimensional textile motion in the moving drum. Furthermore
textile and soiling-specific cleaning and disinfection processes are developed, taking into account
textile prevention from damage. Finally, studies are carried out to reduce the finishing costs.

Abstract
Thermolabile medical devices, inserted in the aseptic visceral cavity, e.g. certain flexible endoscopes,
are subject to stringent hygiene requirements. With regard to reprocessing, they are classified as “critical C”-devices. Due to the polymers used for the construction of these medical devices, they cannot
undergo conventional steam sterilization and have to be sterilized with low temperature sterilization
methods (e.g. ethylene oxide, formaldehyde, plasma or gamma radiation). However, these methods
are technically demanding and have substantial disadvantages. Moreover, some of these methods
are not approved for the sterilisation of the vast majority of flexible endoscopes and many other
“critical-C”-devices. In the course of the wfk project “SteriScope” a novel low-temperature sterilization
procedure using supercritical CO2 (SCCO2) is developed. The procedure will allow a sterilization of
thermolabile, geometrically complex medical devices at temperatures below 40˚C within one hour.
To obtain enhanced performance for the sterilization new additive systems were applied. The supercritical phase status of CO2 exhibits a low viscosity, enabling a sufficient interaction with all surfaces
of even geometrically complex objects. This part of research is performed by the wfk. In parallel
Montanuniversity Leoben (Austria) is developing new nanoparticle enforced polymer materials for
the manufacturing of medical devices. These feature improved barrier performance against small
volatile molecules resulting in improved material compatibility against SCCO2 and also common
sterilants, such as EO. The barrier properties of the newly developed materials towards CO2 were
specifically influenced by the addition of nanocomposites reducing the CO2 adsorption by up to 90
%. The application of 5 % nano-scaled filler showed best results regarding mechanical properties
and resilience of the materials. Suitable process challenge devices with different test soil matrices
applied for the immobilization of microorganisms were developed and used in SCCO2 processes to
page 128
study the sterilizing effect. Various additives and additive combinations were used to enhance sterilization efficacy. Bacterial endospores proved to be the microorganisms with highest tenacity towards
SCCO2 treatment. Further investigations using a suitable sterile barrier system are in progress. To
develop the novel sterilization procedure experimental series investigated the influence of pressure,
pressure-changes and phase transition.

Abstract
The German-Dutch Technology Competence Network Functional Surfaces (TKV FO) carried out a
research and transfer project with 41 partners from scientific and business sectors with a financial
volume of around 7.5 million euros. The collective term “Functional Surfaces” is relevant in almost all
branches of industry and fields of technology, as there is almost always a link to respective product
and topic. Direct transfer is a central project element.
Part of the project (column 1) focused on research in the field of cleaning and hygiene technologies.
The wfk-institute was engaged in the two activities “Low temperature cleaning in food industry” and
“Easy to clean properties of coil-coating-surfaces”. In the first activity, the wfk-institute in collaboration with further project partners developed a floor coating for application in low temperature areas.
This floor coating is based on a biocompatible polymer which can be applied in cold stores under
suitable conditions even at temperatures down to -25 °C and can be crosslinked subsequently to
form a stable coating.
In the second activity, a method for evaluating easy-to-clean-properties was developed. This method enables assessment of soiling and cleaning behaviour of various coil-coating-varnishes as a

order to protect against rain. Depending on the usage a massive contamination of these textiles by
industrial dirt, based on mineral oil derivatives with embedded pigments can occur. Currently used
washing procedures relay on high temperature, alkaline conditions and high washing mechanics
to ensure an adequate soil removal, resulting in a damage of the high-quality textiles and an early
replacement.
In the presented wfk research project a pretreatment method for hydrophobic textiles, based on
microbial functionalized, adhesive (“Pressure Sensitive Adhesive”) pseudoplastic hydrogels was
developed. The approach is based on the adhesive hydrogels, functionalized with oil-degrading
microorganisms (e.g. Pseudomonas stutzeri or Candida maltosa) and their application on soiled sites.
The gels facilitate a direct contact of the dirt-degrading microorganisms and their metabolic products
(e.g. enzymes, bio-surfactants) with the soil. After the pretreatment time (approx. 8h) the textiles and
the hydrogels are subjected to a gentle washing procedure resulting in the removal of the hydrogels
and in excellent removal of the stain. The hydrogel composition (surfactants, nutrient salts, selected
microorganisms) was optimized in order to improve the degradation of mineral oil derivatives and
to shorten the pretreatment time. Comparing the luminance of reprocessed textiles with or without
microbial pretreatment prior to washing a doubling of the soil removal efficiency was demonstrated
for different soilings of practical relevance by the application of this novel pretreatment method. Storage of the microbial functionalized hydrogels was possible for at least three weeks at 4 °C without
affecting the soil degradation performance. The potency of the new method was proved by multiple
experiments in textile service companies. Due to the microbial pretreatment and the subsequent
doubling of cleaning efficiency the portion of textiles that have to be repeatedly laundered can be
reduced and textile damages can be avoided.

Abstract
During reprocessing of several types of protective clothing and surgical textiles like surgical drapes
and gowns surfactant residues have to be removed effectively in the rinsing phase because protective function of those textiles can be negatively influenced. Besides surfactant residues can cause
problems during subsequent hydrophobizaton of textile materials. For these reasons, those textiles
are currently rinsed with high amounts of water. Due to continuously increasing costs of tap water
and waste water as well as increasing investment and operating costs for rinse water treatment, a
more and more intensive economical pressure for industrial laundries occurs.
An opportunity to implement very low surfactant residues is the application of thermolabile surfactants. Such surfactants contain a thermolabile bond which separates the hydrophobic from the
hydrophilic sequence. By bond cleavage thermolabile surfactants lose their surface activity.
The integration of thermolabile surfactants into washing processes was investigated and a method
for surfactant cleavage before rinsing process was developed. For this purpose temperature dependent kinetic of the cleavage rate was determined. Based on these results a theoretical approach
to monitor the concentration of thermolabile surfactants during washing and cleaving processes
was developed and experimentally verified. Thermolabile surfactants showed high stability in washing process and cleaning effects comparable to usual surfactants were obtained. In cleaving process
high cleavage rate was obtained under mild conditions. Accordingly, cleaving products of thermola-
page 130
bile surfactants could easily be removed from textile surfaces with considerably lower amounts of
water during rinsing process compared to usual surfactants. In summary it was possible to optimize
washing procedures with regard to soil removal, minimized surfactant residues and reduced amount
of tap water during rinsing.

Abstract
Due to increasing environmental concerns and new energy regulations, more and more façades are
equipped with thermal insulation. These insulation materials are applied to both refurbishment of old
buildings and construction of new buildings. The main function of heat insulation is to prevent heat
flow from inside the building to the environment, contributing to a significant reduction in heating
costs and carbon dioxide emissions. On the other hand the insulating properties cause a significant
increase of façade temperature during the day due to sunlight and very low façade temperatures,
even below the dew point, by night. The moist and warm façade surface is an ideal breeding ground
for bacteria and algae. In addition, high temperatures lead to resin formation of various types of
dirt on façades. Currently available cleaning methods are often based on high pressure and use
potentially hazardous chemicals. This treatment can cause surface damage depending on the
façade material. In this concluded research project at the wfk-institute a new care procedure for heat
insulating façade materials based on interpenetrating polymer networks was developed. The developed system is an invisible coating, which protects heat-insulating façades against various types of
soil and shows high mechanical, thermal and weather stability. Subsequent to application, formation
of the covalent part of the interpenetrating polymer network is induced by sunlight and the physical
part can be generated by adding a saline solution. Under cleaning conditions, the physical part of the
interpenetrating polymer network dissolves, when the cleaning solution is sprayed on. Consequently,
the IPN-coating can easily be peeled off together with adhering soil e.g. by means of low-pressure
water jets or mechanical treatment.

Abstract
Textile floorings are used in many areas, increasingly also in the health and hygiene sector (e.g.

Poster

high water entry into the flooring material, resulting in long drying times and an associated downtime
for the operator, but also the potential damage to the textile floorings.
In a recently finished research project by wfk, carbon dioxide clathrates (solids, formed under pressure by CO2 and water at low temperatures) were used for cleaning of textile floorings under usage of
a pressure jet system. As the clathrates can be applied as a solid and also removed again as a solid,
no excessive wetting of the textile flooring was observed during application. Thereby, the time periods during which the textile floorings cannot be used could be reduced to a minimum. Furthermore,
the cleaning efficiency and disinfecting effect of the clathrate method was comparable to the spray
extraction method.
Due to these results, the high area performance and low costs, the new method for cleaning textile
floorings with carbon dioxide clathrates represents an advantageous alternative to the conventional
spray extraction process.

Abstract
In textile rental enterprises several types of textiles are equipped with liquid-repellent finishes based
on fluorocarbon resins. In the context of their quality assurance systems textile rental enterprises
have to prove the success of the treatment. At present only complex and expensive test methods
are available which can only be performed by specialized laboratories. The largest part of the costs is
accounted for by the random sampling of textiles treated with liquid repellent finishes. Some of the
tests take a long time or are even destructive, like the test method for resistance of materials to penetration by liquids (DIN EN ISO 6530). In addition, most tests only give results for the small area tested
and not for the whole textile. But the evaluation of the whole surface is crucial, since the temperature
acting on the textile during curing and therefore the resulting liquid repellent effects are not uniformly
distributed over the surface.
Therefore, in addition to the already available product control methods there is a need for a new rapid
method for the process control of the hydrophobization with fluorocarbon resins in textile service
companies. Such a method would allow the reduction of the product controls with standardized
methods. In a recently finished research project, the wfk for the first time produced aggregachromically functionalized liquid-repellent finishes based on novel time-temperature-indicators (TTI) and
applied them onto textiles. After being subjected to a time-temperature-profile needed for thermal
activation of the fluorocarbon resins a specific color change within the TTIs can be observed under
ultraviolet light. This color change can be detected and analyzed right after the thermal treatment on
the whole textile surface with a mobile functional model developed also within the research project.
Thereby it is possible to register whether the time-temperature-profile was met on the entire surface
and hence a rapid method for process control of hydrophobization with fluorocarbon resins based
on aggregachromically functionalized liquid repellent finishes is available.

Abstract
Conventional laundry detergents base mainly on fossil raw materials. In the future, the use of
enzymes in detergents will increase because of a good cleaning effect, inexhaustible availability
and further shortage of fossil raw materials. Proteases, amylases, lipases and cellulases are applied
enzymes in detergents. Whereas proteases and amylases are assumed to be of highest relevance
they were therefore focused in this project. Enzymes are usually applied in low concentrations in
detergents but account for 20 % of detergent production costs. Therefore the laundry industry seeks
for new solutions to recover enzymes and to safe expenses.
In this project a system for the recovery of enzymes was developed. Enzymes were covalently
attached to the surface of superparamagnetic micro particles. In strong magnetic fields these particles are attracted and can be removed from washing liquor. Selected enzymes were immobilised
on suitable micro particles using reactive cyanuric chloride groups resulting in the development
of superparamagnetic protease and amylase systems. These have been exposed to prevalent
constituents of commercial detergents with different concentrations to assess the stability of the
enzyme activity. Several constituents of detergents had no negative effect on the enzymatic activity,
some others decreased the activity. White cotton swatches showed no measurable change for the
“distance of colour” (ΔE) when they were laundered regardless if with or without superparamagnetic
micro particles. A functional model for the magnetic separation of superparamagnetic enzyme systems was developed and constructed in this project. The system applies periodic permanent magnet
(PPM) separation and achieved a 70 % recovery rate of initial 100 mg superparamagnetic enzyme
systems (1.36 ∙ 1011 particles) in 20 L washing liquor within 1 hour. In parallel a washing process was
developed implementing the newly developed superparamagnetic enzyme systems. Based on the
data obtained from this model system an upscaling will be easily possible for future applications in
textile service companies.

Appropriate fast methods for cleaning service enterprises to analyze cleanliness and hygiene in
cleanrooms
Sachgerechte Schnelltests für Reinigungsdienstleister zum Nachweis von Reinheit und Hygiene in
Reinräumen
Edyta Stec, Sabrina Kolbe, Markus Wehrl, Jürgen Bohnen
wfk
Abstract
Cleanrooms are closed system rooms in which the particle content of the air is controlled according
to the specific clean room class. A continuous and comprehensive microbial monitoring of clean
rooms is of high importance and represents a fundamental keystone within the quality management system. Currently, the assessment of the number and type of microorganisms on surfaces
is performed using contact plates or the swab method. A major disadvantage of such classical
microbiological methods is the incubation time and the analysis of samples by external laboratories
that usually takes at least two days.
The aim of the project was the development of a suitable rapid method for the evaluation of the
hygiene of cleaned and disinfected surfaces in cleanrooms. The wfk-institute established a flow
cytometry based method for the determination of total germ count. The identification of microorganisms was realised by a multiplex PCR developed from the Faculty of Health Sciences of the
University Maribor, Slowenia.
For the determination of total germ count of plane and geometrically complex surfaces, a sampling
method based on a sampling pen with an elastic tip that holds the sampling matrix (special clean
room approved wipe, moistened with 0,85 % NaCl solution) was developed. After elution of microorganisms by stomaching, the subsequent quantification of microorganisms is performed using
a 15-minute “one-step” staining with two suitable fluorescent dyes (discrimination of live and dead
cells) in combination with flow cytometric analysis. The entire process, i.e. surface sampling, elution
of microorganisms, cell staining and flow cytometric analysis, requires less than 20 min.

Process for industrial parts cleaning based on shock waves and ionic liquids in dense phase carbon
dioxide
Verfahren zur Reinigung industrieller Teile auf der Basis von Stoßwellen und ionischen
Flüssigkeiten in komprimiertem Kohlendioxid
Patrick Casper, Tamara Neumann-Schmidt, Jürgen Bohnen
wfk
Abstract
A lot of different industrial sectors have particular high demands on cleaning of industrial parts.
They have to be freed from miscellaneous soilings, ranging from small particles to oily films. Thus,
type and amount of these soils are highly varying. The level of cleanliness and the required cleaning
process is controlled by the subsequent use or processing of the parts, respectively. On the one
hand state of the art is cleaning with halogen-free solvents (e.g. hydrocarbons) or (to a lesser extent)
with chlorinated solvents. On the other hand common cleaning is also carried out with water-based
systems.
page 134
From a procedural, economical, and ecological point of view both organic solvents and waterborne
systems have different drawbacks. Moreover, after cleaning these solvents have to be subjected to
complex recycling processes. In case of heavily soiled surfaces the sole mechanical application of
the mentioned solvents may not be sufficient and a manual cleaning with organic solvents is necessary. This cleaning is very labor- and cost- intensive. Furthermore, special measures are demanded in
terms of occupational safety as well as health and environmental protection.
A promising alternative to the existing cleaning systems is offered by dense phase carbon dioxide
(DPCO2). DPCO2 has a high dissolving power for hydrophobic substances as well as a high gap penetration. It requires no drying as it evaporates residue-free already at atmospheric pressure. Cleaning
and recovery is achieved simply “by distillation”. Furthermore it is cheap, available in high purity
grades and unlimited amounts, non-combustible, and toxicologically and environmentally harmless.
In some applications DPCO2 is already used as an alternative to nonpolar organic solvents whereas
in industrial parts cleaning it hasn’t been used routinely so far. But there are still some shortcomings
in the removal of particulate and/or polar soils when it comes to an implementation into the cleaning
of industrial parts. These shortcomings are due to low mechanical action of DPCO2 during cleaning
process because of its low viscosity and disability as a nonpolar solvent to dissolve polar soils.
In a recently finished research project the wfk developed a process for cleaning of industrial parts on
the basis of shock waves, ionic liquids and further additives in compressed carbon dioxide.

Quick self check method to evaluate the resistance of surgical drapes, gowns and clean air suites
against microbial penetration in the dry state
Innerbetriebliche Schnellmethode zur Beurteilung der Widerstandsfähigkeit von Operationsabdecktüchern, OP-Mänteln und Rein-Luft-Kleidung gegen mikrobielle Penetration im trockenen Zustand
Abstract
Testing the barrier function of surgical textiles like gowns, drapes and clean-air-suits for bacterial
penetration under dry conditions (“dry penetration”) according to EN ISO 22612 involves bacterial
endospores of Bacillus atrophaeus and is therefore usually performed by specialized test laboratories. The testing is time-consuming and susceptible to errors. According to DIN EN 13795 alternative
testing methods can be applied for the evaluation of the processed surgical textiles. But up to now
there was no alternative method that allowed a fast and easy assessment of barrier performance in
the dry state to be performed by e.g. textile service providers on their own.
The approach of the presented wfk research project relied on the substitution of the conventionally
used bacterial endospores against enzymatic particles (“glassbeads”) of the same size and same
penetration behaviour when mixed with talcum as described in EN ISO 22612. The penetrated
glassbead-talcum-particles were fixed on a membrane and detected within 1.5 h via a chemiluminescence-assay. The established dry penetration test with glassbeads is faster than the conventional
method. This allows a direct separation of textiles which exceed the limits for barrier function. As the
test is easy and fast to apply, robust against errors and can be conducted with minimum effort, the
results are going to be presented in ISO/TC94/SC13/WG6, the standardisation group that will start
the revision of EN ISO 22610 in 2015/2016.

Abstract
Floorcare products are used in practice to increase lifetime and maintain the optical appearance
of elastic floorings. Temporary coatings of elastic floorings protect them from scratches, abrasion,
tracks and improve their cleanability. At longer contact times some soilings (e.g. iodine containing disinfectants, hair tinting lotions, shoepolishs, fats and mineral oils) migrate through applied
polymeric coatings into the top layer of floorings itself, leading to irreparable damages. Furthermore
discolorations can also be caused by an exchange of plasticizers between dark colored furniture
gliders, car tyres, bicylce tyres and elastic floorings. Such soils have to be removed from elastic
floorings immediately to avoid irreparable damages.
In a research project at wfk (Krefeld) two different approaches to improve the barrier function of polymer coatings were investigated. One approach is based on extending diffusion path by embedding
anorganic barrier pigments in the lowest layer of conventional anionic polymer coating, which is in
direct contact to flooring. Typical, conventional polymer coatings consist of three layers. In the second approach, a cationic polymer layer was integrated between two layers of commercially available
floorcare products with the aim to function as “soiling trap”.
Permeation of selected soils (especially hair tinting lotions) through conventional polymeric coatings
was reduced by both modification of the lowest layer with barrier pigments and integration of a
cationic compound. Detectable soiling residues were dependent on the type of soil, applied conventional floorcare product, type and concentration of the barrier pigment resp. the cationic polymer
dispersion.
Developed polymer coatings with improved barrier function for permeative soil components did not
cause changes in brightness and color of elastic flooring. A low reduction of gloss was observed in
comparison to unmodified coating. Furthermore an impact on adhesive strength, abrasion resistance and slip resistance was not detected.
Project results show that it should be possible to develop polymeric coatings for special application
areas, for example hospitals or hairdresser’s shops, where permeating soils like iodine ointment or
hair tinting lotions could be expected.

Abstract
Surgical textiles are medical devices according to the medical device directive 93/42/EEC and have
to meet various specifications regarding their technical properties given in EN 13795. One of the most
important features of surgical textiles is their barrier function against bacterial penetration under wet
conditions (“wet penetration”). Wet penetration is determined using the methodology according to EN
ISO 22610, using cells of the pathogenic Staphylococcus aureus as test organisms and has therefore to be conducted by specialized test laboratories. The analysis usually takes 4 days and causes
high expenses for customers that have to assess wet penetration periodically.
The aim of the presented research project was the development of a biochemical method for testing
wet penetration fast and easily as a self-control. The approach based on the substitution of the
bacterial test organisms by special enzymatically functionalised polymer particles with the size
of bacteria which should be visualised after penetrating the surgical textiles to allow easy detection. Several enzyme-substrate-systems were chosen for generating a visible colour reaction on
substrate containing gels. Enzymes were immobilised on different microparticles whereby peroxidase-microparticles have shown the best results. A detection of single microparticles was possible
using a chemiluminescence assay. By performing the Rulla II-method (EN ISO 22610), it was shown
that the microparticles did not penetrate sufficiently through textile structures. Therefore, first experiments using functionalized liposomes were conducted. By functionalization of liposomes with a
fluorescence dye, a simple visualization of single particles was possible and the barrier performance
of surgical textiles could be judged immediately after testing.
