Work out denier to tex conversion instantly with clear inputs, formula shown and shareable results.
Denier is grams per 9000 metres and tex is grams per 1000 metres, so tex = denier / 9 and decitex = denier x 10 / 9. Denier per filament, the total denier divided by filament count, is the figure that governs fabric handle and softness in filament yarns.
Denier and tex
tex = denier / 9; decitex = denier x 10 / 9; denier = tex x 9
Per filament
Denier per filament = total denier / filament count
A 150 denier yarn with 48 filaments feels quite different from one with 144. Microfibre is generally defined as below 1 denier per filament, giving a soft, dense handle.
Decitex is the ISO preference for filament yarns because it gives convenient whole numbers, and tex for staple yarns. Denier persists commercially in synthetic filament trade.
