Filament Count Specification Targets for Buyers
Setting Filament Count correctly on a tech pack prevents most later disputes. Targets belong on the page before the first fabric sample.
Where to write it
Place Filament Count next to composition and weight so all three are quoted as one package. Working figures for Filament Count normally sit around 34, 72 or 144 filaments typical in mainstream production. Note mill specification on the tech pack so nobody tests against an older revision.
Reference level
Typical activewear expectation: 34, 72 or 144 filaments typical. Record elastane content alongside Filament Count, because blends shift the measured value. A result outside 34, 72 or 144 filaments typical 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 Filament Count lets suppliers quote without extra sampling rounds. Ask for conditioning details together with mill specification, since both affect the reading.
Verification method
Confirm with mill specification and keep the report against the bulk record. Working figures for Filament Count normally sit around 34, 72 or 144 filaments typical in mainstream production. Note mill specification 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 Filament Count, because blends shift the measured value. A result outside 34, 72 or 144 filaments typical usually points to process drift rather than to the fibre itself.
