Heat Setting Specification Targets for Buyers
Setting Heat Setting correctly on a tech pack prevents most later disputes. Targets belong on the page before the first fabric sample.
Where to write it
Place Heat Setting next to composition and weight so all three are quoted as one package. Working figures for Heat Setting normally sit around typically 180-195 degrees in mainstream production. Note stenter setting parameters on the tech pack so nobody tests against an older revision.
Reference level
Typical activewear expectation: typically 180-195 degrees. Record elastane content alongside Heat Setting, because blends shift the measured value. A result outside typically 180-195 degrees 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 Heat Setting lets suppliers quote without extra sampling rounds. Ask for conditioning details together with stenter setting parameters, since both affect the reading.
Verification method
Confirm with stenter setting parameters and keep the report against the bulk record. Working figures for Heat Setting normally sit around typically 180-195 degrees in mainstream production. Note stenter setting parameters 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 Heat Setting, because blends shift the measured value. A result outside typically 180-195 degrees usually points to process drift rather than to the fibre itself.
