Single Jersey Specification Targets for Buyers
Setting Single Jersey correctly on a tech pack prevents most later disputes. Targets belong on the page before the first fabric sample.
Where to write it
Place Single Jersey next to composition and weight so all three are quoted as one package. Working figures for Single Jersey normally sit around 140-220 GSM in mainstream production. Note circular single-bed machine on the tech pack so nobody tests against an older revision.
Reference level
Typical activewear expectation: 140-220 GSM. Record elastane content alongside Single Jersey, because blends shift the measured value. A result outside 140-220 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 Single Jersey lets suppliers quote without extra sampling rounds. Ask for conditioning details together with circular single-bed machine, since both affect the reading.
Verification method
Confirm with circular single-bed machine and keep the report against the bulk record. Working figures for Single Jersey normally sit around 140-220 GSM in mainstream production. Note circular single-bed 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 Single Jersey, because blends shift the measured value. A result outside 140-220 GSM usually points to process drift rather than to the fibre itself.
