Fabric Growth Specification Targets for Buyers
Setting Fabric Growth correctly on a tech pack prevents most later disputes. Targets belong on the page before the first fabric sample.
Where to write it
Place Fabric Growth next to composition and weight so all three are quoted as one package. Working figures for Fabric Growth normally sit around below 6% target in mainstream production. Note ASTM D2594 stretch properties on the tech pack so nobody tests against an older revision.
Reference level
Typical activewear expectation: below 6% target. Record elastane content alongside Fabric Growth, because blends shift the measured value. A result outside below 6% target 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 Fabric Growth lets suppliers quote without extra sampling rounds. Ask for conditioning details together with ASTM D2594 stretch properties, since both affect the reading.
Verification method
Confirm with ASTM D2594 stretch properties and keep the report against the bulk record. Working figures for Fabric Growth normally sit around below 6% target in mainstream production. Note ASTM D2594 stretch properties 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 Fabric Growth, because blends shift the measured value. A result outside below 6% target usually points to process drift rather than to the fibre itself.
