Nowadaysmixingof polymersand theirspinningis a

mixingof commercialpolymerswere publishedand a

textilefabricspropertiesthe very importantrole are
beingplayedin the interactionforcesbetweenfibresand
their aggregates.There are the frictionforcesthat are

The drapeis definedas the deformation

force.Therefore
for the drape measurementsthe differentset up and
techniquecan be used.In the firsttechnique(1950)the
circletextilesampleof the known radiusR is being
coaxiallysituatedon the solidcirclebaseof the radius

forceis deformingthe

Firendly
Productgoesalreadyon for over5 years,it is not possibleto evaluateit as verysuccessfulone becauseonly
32 productsfrom 9 manufacturershave been awarded
the labeluntilnow.Onlytwo textileproductshavebeen
labelled.Lowereconomicefficiencyof the Slovakenterprisesis givenas the main reason.However,the
reasonis morelikelyon the sideof manufacturers
and
partlyalsoon the sideof publicin our opinionbecause
thereare also economically
strongerenterprisesthan
BZ Texicomwhichdid not show interestin the labelfor
