Pilling Resistance How to Read It on a Lab Report
Laboratory reports present Pilling Resistance in a compact format. Knowing what each line means prevents misreading.
Definition reminder
resistance to surface fibre balls. 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.
Common report layout
The report states method ISO 12945-2 pilling box, sample description, conditioning, and the measured result. 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.
Typical result
Values near grade 4 after 7000 revolutions usually indicate a conforming lot, assuming the fabric matches the sample submitted. 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.
Red flags
Missing revision numbers, unusual conditioning, and results without units all signal unreliable data. 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.
Questions to ask
Ask the laboratory for the standard revision and sample description before accepting or rejecting a result. 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.
