Hvorfor specificere kationisk polyester i stedet for standard polyester?
Kationisk polyester accepts dye at lower temperature and pressure and produces deeper shade depth on pastel and mid-tone colors. For lightsteelblue, the difference is visible in the richness of the shade and the reduced risk of a flat or washed-out appearance.
Hvordan bør et indhold af 25 % elastan have indflydelse på tests på beklædningsgenstanden?
Højt indhold af elastan betyder, at stoffet vil komprimere kroppen i stedet for at drapere over det. Tilpasningsforsøg bør udføres på kroppen eller på former, der repræsenterer målbæreren, med opmærksomhed på sømplacering og trykpunkter. Mønsterklassificering bør tage højde for stoffets genopretningskraft.
Hvilken farvevariation kan forventes på tværs af partier?
Kationisk dyeing is sensitive to dyestuff selection and bath control. Retain a physical standard from the approved first lot and match subsequent lots against it under the intended lighting condition. Minor drift in pastel shades is possible and should be agreed before bulk commitment.
Påvirker kationisk farvning farveægtheden?
Kationisk dyeing produces good wash and light fastness when dyestuff selection and after-treatment are controlled. Confirm fastness results against your market requirements during sampling, particularly for swim and active programs where exposure to chlorine and sunlight is expected.
Er dette stof velegnet til klorpoolmiljøer?
Elastan has limited resistance to prolonged chlorine exposure. For frequent pool use, chlorine-resistant elastane grades or alternative fiber bases should be evaluated. For occasional swim use, the fabric performs within normal expectations when rinsed after exposure.
