Abrasion Resistance How to Read It on a Lab Report
Laboratory reports present Abrasion Resistance in a compact format. Knowing what each line means prevents misreading.
Definition reminder
cycles before the surface breaks. Working figures for Abrasion Resistance normally sit around above 20000 cycles for heavy use in mainstream production. Note ASTM D4966 Martindale abrasion on the tech pack so nobody tests against an older revision.
Common report layout
The report states method ASTM D4966 Martindale abrasion, sample description, conditioning, and the measured result. Record elastane content alongside Abrasion Resistance, because blends shift the measured value. A result outside above 20000 cycles for heavy use usually points to process drift rather than to the fibre itself.
Typical result
Values near above 20000 cycles for heavy use usually indicate a conforming lot, assuming the fabric matches the sample submitted. Keeping reference values for Abrasion Resistance lets suppliers quote without extra sampling rounds. Ask for conditioning details together with ASTM D4966 Martindale abrasion, since both affect the reading.
Red flags
Missing revision numbers, unusual conditioning, and results without units all signal unreliable data. Working figures for Abrasion Resistance normally sit around above 20000 cycles for heavy use in mainstream production. Note ASTM D4966 Martindale abrasion 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 Abrasion Resistance, because blends shift the measured value. A result outside above 20000 cycles for heavy use usually points to process drift rather than to the fibre itself.
