Denier (D) Specification Targets for Buyers
Setting Denier (D) correctly on a tech pack prevents most later disputes. Targets belong on the page before the first fabric sample.
Where to write it
Place Denier (D) next to composition and weight so all three are quoted as one package. Working figures for Denier (D) normally sit around 20-150 denier in activewear in mainstream production. Note ASTM D1907 yarn number on the tech pack so nobody tests against an older revision.
Reference level
Typical activewear expectation: 20-150 denier in activewear. Record elastane content alongside Denier (D), because blends shift the measured value. A result outside 20-150 denier in activewear 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 Denier (D) lets suppliers quote without extra sampling rounds. Ask for conditioning details together with ASTM D1907 yarn number, since both affect the reading.
Verification method
Confirm with ASTM D1907 yarn number and keep the report against the bulk record. Working figures for Denier (D) normally sit around 20-150 denier in activewear in mainstream production. Note ASTM D1907 yarn number 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 Denier (D), because blends shift the measured value. A result outside 20-150 denier in activewear usually points to process drift rather than to the fibre itself.
