Hvorfor spesifisere 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 25 % elastaninnhold påvirke plaggpassformprøver?
Høyt innhold av elastan betyr at stoffet vil komprimere kroppen i stedet for å drapere over den. Tilpasningsforsøk bør utføres på kroppen eller på former som representerer målbrukeren, med oppmerksomhet på sømplassering og trykkpunkter. Mønstergradering bør ta hensyn til gjenopprettingskraften til stoffet.
Hvilken nyansevariasjon bør forventes på tvers av partiene?
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 farging fargefastheten?
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 stoffet egnet for klorbassengmiljøer?
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.
