Tensile Strength Specification Targets for Buyers
Setting Tensile Strength correctly on a tech pack prevents most later disputes. Targets belong on the page before the first fabric sample.
Where to write it
Place Tensile Strength next to composition and weight so all three are quoted as one package. Working figures for Tensile Strength normally sit around above 150 N for most knits in mainstream production. Note ISO 13934-1 strip test on the tech pack so nobody tests against an older revision.
Reference level
Typical activewear expectation: above 150 N for most knits. Record elastane content alongside Tensile Strength, because blends shift the measured value. A result outside above 150 N for most knits 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 Tensile Strength lets suppliers quote without extra sampling rounds. Ask for conditioning details together with ISO 13934-1 strip test, since both affect the reading.
Verification method
Confirm with ISO 13934-1 strip test and keep the report against the bulk record. Working figures for Tensile Strength normally sit around above 150 N for most knits in mainstream production. Note ISO 13934-1 strip test 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 Tensile Strength, because blends shift the measured value. A result outside above 150 N for most knits usually points to process drift rather than to the fibre itself.
