About Tex (tex)
A textile-industry linear-density unit equal to exactly grams per 1,000 meters of fiber or yarn (= 10⁻⁶ kg/m = 1 mg/m). Tex is the ISO-standard fiber-fineness unit worldwide per ISO 2060 'Yarn from Packages — Determination of Linear Density (Mass per Unit Length)'. Used universally in: tire-cord industry per ASTM D885 (polyester tire cord 1,100-1,650 tex; rayon cord 1,840-2,750 tex; aramid/Kevlar cord 1,580-2,840 tex; steel-wire tire-belt 4,400 tex), industrial belting and conveyor-belt reinforcement fabrics, carpet and rug yarn (Berber loop-pile typical 2,000-5,000 tex; nylon BCF 1,400 tex), sewing-thread and embroidery-thread specifications, polypropylene woven slings for material handling, and continuous-filament-yarn (CFY) manufacturing. Direct measurement principle: weigh 1,000 m of the fiber under standardized 20 °C / 65% RH atmosphere per ISO 139, heavier fiber = higher tex. Convert tex to g/km (numerically identical); to denier by multiplying by 9; to kg/m by dividing by 10⁶.
About Denier (den)
A textile-industry linear-density unit equal to exactly grams per 9,000 meters of fiber or yarn (≈ 1.111 × 10⁻⁷ kg/m = 0.1111 tex). The 9,000-meter basis is preserved from the historic Lyon, France silk-trade measurement standard. Denier ('den' or simply 'D') is the everyday consumer-textile fineness unit: pantyhose and nylon-stocking weight ratings (10-15 den ultra-sheer; 20-40 den medium; 40-80 den opaque; 100-200 den support hosiery), fishing-line braided ratings (Sufix 832, PowerPro, Daiwa J-Braid product lines list denier alongside lb-test), parachute-cord and military 550-cord nylon ripstop fabric per MIL-DTL-32439 (210D - 1680D ranges), outdoor-gear rip-stop nylon and Cordura fabric specifications (Cordura 1000D is the rugged standard for backpacks and tactical equipment; 500D and 330D are lighter weights; Cordura HP and TrueLock have engineered variants), and silk-fabric weight ratings (4.5-8 momme silk shirting; 35+ momme heavyweight silk). 1 denier ≈ 0.111 tex ≈ 1.111 × 10⁻⁷ kg/m.
