Dtex to Denier: when you need it

Yarn from European spinners, and many technical or export specifications, arrives in decitex: "dtex 167 f48" or "84 dtex". Surat mills and traders price filament in denier, so the spec has to be converted before it can be compared with a local yarn rate.

Spec sheets round dtex to whole numbers, so the denier you get may not be round either. 167 dtex gives 150.3 denier, which is the yarn the market calls 150 denier.

Formula: denier = dtex × 0.9

denier = dtex × 0.9. Denier weighs 9,000 m and dtex 10,000 m of the same yarn, so the denier figure is nine tenths of the dtex figure.

Worked example

167 dtex: 167 × 0.9 = 150.3 denier.

FAQ

Questions

How many denier is 167 dtex?

150.3 denier (167 × 0.9). It is the dtex figure suppliers give for a 150 denier yarn, rounded up from 166.7.

What is the formula for dtex to denier?

denier = dtex × 0.9. 84 dtex × 0.9 = 75.6 denier, which is sold as 75 denier.

What does dtex 167 f48 mean?

167 decitex made of 48 filaments: about 150 denier, with 3.479 dtex (3.131 denier) per filament. Enter 48 as the filament count to see this in the converter.

Is 22 dtex the same as 20 denier?

Very close: 22 dtex × 0.9 = 19.8 denier. 20 denier is exactly 22.22 dtex, and spec sheets round that to 22.

Which is finer, 110 dtex or 100 denier?

They are almost the same yarn. 110 dtex is 99 denier, while 100 denier is 111.1 dtex, so 110 dtex is very slightly finer.
