Skewing and Spirality Specification Targets for Buyers
Setting Skewing and Spirality correctly on a tech pack prevents most later disputes. Targets belong on the page before the first fabric sample.
Where to write it
Place Skewing and Spirality next to composition and weight so all three are quoted as one package. Working figures for Skewing and Spirality normally sit around below 3% displacement in mainstream production. Note AATCC 179 skewness on the tech pack so nobody tests against an older revision.
Reference level
Typical activewear expectation: below 3% displacement. Record elastane content alongside Skewing and Spirality, because blends shift the measured value. A result outside below 3% displacement 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 Skewing and Spirality lets suppliers quote without extra sampling rounds. Ask for conditioning details together with AATCC 179 skewness, since both affect the reading.
Verification method
Confirm with AATCC 179 skewness and keep the report against the bulk record. Working figures for Skewing and Spirality normally sit around below 3% displacement in mainstream production. Note AATCC 179 skewness 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 Skewing and Spirality, because blends shift the measured value. A result outside below 3% displacement usually points to process drift rather than to the fibre itself.
