Colour Fastness to Chlorinated Water What Improves It and What Damages It
Practical actions that raise or lower Colour Fastness to Chlorinated Water during knitting, dyeing, finishing and garment care.
Actions that help
Correct construction choice and controlled setting improve performance, and they also keep the fabric near grade 4 at 1 ppm chlorine. Working figures for Colour Fastness to Chlorinated Water normally sit around grade 4 at 1 ppm chlorine in mainstream production. Note ISO 105-E03 chlorinated water on the tech pack so nobody tests against an older revision.
Actions that damage it
Excess heat, over-aggressive softener and missing washing-off steps all reduce results. Record elastane content alongside Colour Fastness to Chlorinated Water, because blends shift the measured value. A result outside grade 4 at 1 ppm chlorine usually points to process drift rather than to the fibre itself.
Finishing influence
ISO 105-E03 chlorinated water results shift noticeably after finishing, so retest after the final process rather than before. Keeping reference values for Colour Fastness to Chlorinated Water lets suppliers quote without extra sampling rounds. Ask for conditioning details together with ISO 105-E03 chlorinated water, since both affect the reading.
Garment care influence
Home washing temperature and drying method change performance over the first ten cycles. Working figures for Colour Fastness to Chlorinated Water normally sit around grade 4 at 1 ppm chlorine in mainstream production. Note ISO 105-E03 chlorinated water on the tech pack so nobody tests against an older revision.
Summary
Keep process settings documented so repeat orders land inside the agreed range every time. Record elastane content alongside Colour Fastness to Chlorinated Water, because blends shift the measured value. A result outside grade 4 at 1 ppm chlorine usually points to process drift rather than to the fibre itself.
