Filament Count Setting It Correctly on a Tech Pack
Filament Count should be written into the tech pack with a value, a tolerance and a method. This removes ambiguity from quotations.
Definition to agree
number of individual filaments in one yarn bundle. 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.
Target value
Open the specification at 34, 72 or 144 filaments typical, adjusted to the end use. 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.
Method line
Always pair the target with mill specification so the mill and the laboratory test the same way. 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.
Tolerance line
State plus or minus limits to keep production realistic while protecting the requirement. 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.
Approval step
Approve the result on pre-production bulk rather than on development fabric only. 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.
