Introduction Nowadaysmixingof polymersand theirspinningis a commonmethodto preparemodifiedfibreswith better properties.Many researchworks and papers about mixingof commercialpolymerswere publishedand a modificationof commercialfibre-formingpolymerswith differentotheradditivesis describedas well.

The hydrophilicity of modifiedfibresis positively influencedespeciallyby an introduction of nonextracted lt is causedbasicallyby a presenceof copolyamides. lowmolecular compounds(LMC)as it is shownin Table 2 and demonstratedby diferencesbetweenwater and extractedmodified vapoursorptionof nonextracted PA 6 fibres.PA 6 blendspreparedfrom PA 6 and by a copolyamideslN2 | and lN2 ll are characterized higherpartof LMC.Valuesof LMC amountfor relevant (8)(lN2| equalto 14.2w1.o/0,lN2 ll equal copolyamides 131 to 55.5wL.% and INBequalto21.5wt. %) confirmstheir relativelyhighamountof extractible fractionswhatmanifestsin the modifiedPA 6 fibresas well.Generally4055 % of all amountof copolyamideAN2 | and AN2 ll is removedby extractionfrom modifiedfibres.ln the case o f I N B t h e s i t u a t i o ni s b e t t e r a n d t h e a m o u n t o f extractibleadditivesis 22-35 % (Table3). Tensilestrength,TS, of modifiedPA 6 fibresis negativelyinfluenced.The lowermolecularweightof copolyamides,higheramountof LMC and higheramountof c o p o l y a m i d ei n P A 6 c a u s e a d e c r e a s ei n t e n s i l e strengthof PA 6 fibresmodifiedwith all three copolyamides.The additionof 10 and 20 wt. % of any lN2 copolyamide leadsto a decreaseof tensilestrengthto 82-86% of nonmodifiedPA 6 tensilestrength.30 wt. % of lN2 copolyamidecausesthe reductionto the level 7+75 %. Additionof 10 wt. o/oof INB copolyamide causesa decreaseto the levelof 91 % while20 and 30 wt. % reduceTS to the level 72-79 % of pA 6 tensilestrength. Elongation, E, is practicallynot changed,elasticdegree,e0,and orientationfactor,f, of modifiedPA 6 fibres are positivelyinfluenced.lt couldbe explainedby the effectof low-molecular compoundspresentin the system. LMC functionprobablyas an internallubricant helpingin the orientationof macromolecules during spinninganddrawing. 4. Conclusions 1.

Electricalpropertiesof modifiedPA 6 fibresare better especiallyby usingINB copolyamide. 3. Hydrophilicity is basicallyimprovedonly for nonextractedmodifiedPA fibres. 4.

Fromthe linear,planaras well as volume distributionof the fibresthe yarns and planarstructure are beingcreated.In the staticstructurethe positions of the individualfibresare beingdescribed,in the dynamicalone the movementof the fibresin the textile fabricsis beingconsideredalso.The planarstructureof textilesis beingcarriedout as the woven,knittingand web fabrics.The knowledgeof the textilefabricstructure is very importantfor the technologyof the production of the textilesof the requestedproperties.In the textilefabricspropertiesthe very importantrole are beingplayedin the interactionforcesbetweenfibresand their aggregates.There are the frictionforcesthat are beingheldthe fibrestogetheras in the yarnsas well as in the woven,knittingand nonwoventextiles.In the knitting and woven fabricsthe distributionof the fibres is periodic,in the web fabricsaperiodicone. The objectof our researchthereare the wovenfabricsthat havealso the periodicdistributionof the bondingforces representedthroughthe bond points in the woven fabrics. The bondingpointsare beingcreatedthe bond of the wovenand they can be used also as the structureelementsof the wovenfabric.When thesebondpointsare beingrepresented throughthe geometricalpoints,the complicatedwoven structureis being represented troughthe planarpoint lattice.For the structurerepresentationand descriptionof this latticethe two-dimensionalcrystallatticecan be appliedand with it the all mathematical apparatus.All thiswill be donein the folpaper. lowing Thus supposedthe textilesstructureis of inducingthe basisof the anisotropyof the properties the wovenfabricsas for instancethe mechanicalmoduli 142 and strengthof the textilesare.

In reality,there is no "plateau"with constant of the heatflowgoingthough valueq at the registration the systemwith PCM layers,becausePCM layeris not continuousin usualapplicationin textiles.A non refibresfrom outside ducedheatflow penetratesbeWveen layer,and as a result of it the curve of heat flow is smoothand continuousand remindsagainan exponential one. How can we then simplyevaluatetimeof protection? a lot ln physics,the exponentialcurvescharacterize of naturalprocesses,as e.g. radioactiveisotopedecay. Forsimpleexpressionof the radiationintensitydrop,the whichis givenby halftimewas introduced, radioactive time necessaryfor drop of radiatelevelintensityto half. This parameteris useful,becauseit is clearfor understanding.Similarly,analogyof this parameterwill be usedfor evaluationof the thermalprotectiveefficiency of fabricscontainingPCM elements.
