AZO Dye Restrictions What Improves It and What Damages It
Practical actions that raise or lower AZO Dye Restrictions 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 below 30 ppm per amine. Working figures for AZO Dye Restrictions normally sit around below 30 ppm per amine in mainstream production. Note EN 14362 determination 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 AZO Dye Restrictions, because blends shift the measured value. A result outside below 30 ppm per amine usually points to process drift rather than to the fibre itself.
Finishing influence
EN 14362 determination results shift noticeably after finishing, so retest after the final process rather than before. Keeping reference values for AZO Dye Restrictions lets suppliers quote without extra sampling rounds. Ask for conditioning details together with EN 14362 determination, since both affect the reading.
Garment care influence
Home washing temperature and drying method change performance over the first ten cycles. Working figures for AZO Dye Restrictions normally sit around below 30 ppm per amine in mainstream production. Note EN 14362 determination 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 AZO Dye Restrictions, because blends shift the measured value. A result outside below 30 ppm per amine usually points to process drift rather than to the fibre itself.
