Abrasion Resistance Setting It Correctly on a Tech Pack
Abrasion Resistance should be written into the tech pack with a value, a tolerance and a method. This removes ambiguity from quotations.
Definition to agree
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.
Target value
Open the specification at above 20000 cycles for heavy use, adjusted to the end use. 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.
Method line
Always pair the target with ASTM D4966 Martindale abrasion so the mill and the laboratory test the same way. 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.
Tolerance line
State plus or minus limits to keep production realistic while protecting the requirement. 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.
Approval step
Approve the result on pre-production bulk rather than on development fabric only. 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.
