Frequently asked questions
How many tex is 150 denier?
150 denier = 150 ÷ 9 = 16.67 tex (equivalent to 60 Nm). Denier is the weight of 9,000 m, tex of 1,000 m of yarn.
What is the difference between denier and dtex?
Denier is the gram weight of 9,000 m, dtex of 10,000 m. Conversion: dtex = denier × 1.111.
What are direct and indirect count systems?
Direct systems (tex, denier, dtex) measure weight per length — a higher value means a coarser yarn. Indirect systems (Nm, Ne) measure length per weight — a higher value means a finer yarn.
Why is the Ne constant 590.5 for polyester?
The Ne–Tex constant is 590.5 for pure synthetics; cotton uses 583.1 because of moisture. This tool assumes 590.5 for polyester.
