Interlock Specification Targets for Buyers
Setting Interlock correctly on a tech pack prevents most later disputes. Targets belong on the page before the first fabric sample.
Where to write it
Place Interlock next to composition and weight so all three are quoted as one package. Working figures for Interlock normally sit around 200-280 GSM in mainstream production. Note interlock machine on the tech pack so nobody tests against an older revision.
Reference level
Typical activewear expectation: 200-280 GSM. Record elastane content alongside Interlock, because blends shift the measured value. A result outside 200-280 GSM 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 Interlock lets suppliers quote without extra sampling rounds. Ask for conditioning details together with interlock machine, since both affect the reading.
Verification method
Confirm with interlock machine and keep the report against the bulk record. Working figures for Interlock normally sit around 200-280 GSM in mainstream production. Note interlock machine 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 Interlock, because blends shift the measured value. A result outside 200-280 GSM usually points to process drift rather than to the fibre itself.
