Filament Count Frequently Asked Questions
Short answers to the questions buyers ask most often about Filament Count.
What does it mean?
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.
What value should be specified?
Start from 34, 72 or 144 filaments typical and adjust for the end use of the garment. 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.
How is it tested?
mill specification. 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.
Why does it change between lots?
Process variables such as finishing temperature and elastane batch cause the normal spread of results. 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.
Can results be compared across suppliers?
Only when the same standard revision and conditioning are used; otherwise measurements are not equivalent. 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.
