Pilling Resistance What Improves It and What Damages It
Practical actions that raise or lower Pilling Resistance 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 after 7000 revolutions. Working figures for Pilling Resistance normally sit around grade 4 after 7000 revolutions in mainstream production. Note ISO 12945-2 pilling box 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 Pilling Resistance, because blends shift the measured value. A result outside grade 4 after 7000 revolutions usually points to process drift rather than to the fibre itself.
Finishing influence
ISO 12945-2 pilling box results shift noticeably after finishing, so retest after the final process rather than before. Keeping reference values for Pilling Resistance lets suppliers quote without extra sampling rounds. Ask for conditioning details together with ISO 12945-2 pilling box, since both affect the reading.
Garment care influence
Home washing temperature and drying method change performance over the first ten cycles. Working figures for Pilling Resistance normally sit around grade 4 after 7000 revolutions in mainstream production. Note ISO 12945-2 pilling box 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 Pilling Resistance, because blends shift the measured value. A result outside grade 4 after 7000 revolutions usually points to process drift rather than to the fibre itself.
