Common questions

Is denier the same as GSM?
No. Denier is yarn. GSM is the woven fabric mass.
What is Ne here?
English cotton count as used on yarn conversion sheets, not a lab certificate.
How is yarn denier calculated from weight and length?
Denier = (Weight in grams × 9,000) / Length in meters. By definition, 1 Denier means that 9,000 meters of continuous yarn weighs exactly 1 gram.
How to convert Denier to Tex, Dtex, and English Cotton Count (Ne)?
Standard direct and indirect yarn conversion formulas: Tex = Denier / 9; Dtex = Denier × 1.111; Ne (cotton count) ≈ 5,315 / Denier; Nm (metric count) ≈ 9,000 / Denier.
What does DPF mean in polyester filament yarn?
DPF stands for Denier Per Filament, calculated as Total Denier / Filament Count. For example, 75D/72F has DPF ≈ 1.04. In textile specifications, microfiber is defined as any filament with DPF < 1.0.
