Pilling Resistance Specification Targets for Buyers
Setting Pilling Resistance correctly on a tech pack prevents most later disputes. Targets belong on the page before the first fabric sample.
Where to write it
Place Pilling Resistance next to composition and weight so all three are quoted as one package. 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.
Reference level
Typical activewear expectation: grade 4 after 7000 revolutions. 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.
Tolerances that work
Allow a small tolerance rather than a fixed number, since normal process variation exists in every lot. 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.
Verification method
Confirm with ISO 12945-2 pilling box and keep the report against the bulk record. 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.
Commercial note
Tightening beyond practical need raises cost without improving garment life, so set the tightest target only where it protects the customer. 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.
