Dimensional Stability Specification Targets for Buyers
Setting Dimensional Stability correctly on a tech pack prevents most later disputes. Targets belong on the page before the first fabric sample.
Where to write it
Place Dimensional Stability next to composition and weight so all three are quoted as one package. Working figures for Dimensional Stability normally sit around under 3% length, 4% width in mainstream production. Note AATCC 135 home laundering on the tech pack so nobody tests against an older revision.
Reference level
Typical activewear expectation: under 3% length, 4% width. Record elastane content alongside Dimensional Stability, because blends shift the measured value. A result outside under 3% length, 4% width 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 Dimensional Stability lets suppliers quote without extra sampling rounds. Ask for conditioning details together with AATCC 135 home laundering, since both affect the reading.
Verification method
Confirm with AATCC 135 home laundering and keep the report against the bulk record. Working figures for Dimensional Stability normally sit around under 3% length, 4% width in mainstream production. Note AATCC 135 home laundering 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 Dimensional Stability, because blends shift the measured value. A result outside under 3% length, 4% width usually points to process drift rather than to the fibre itself.
