The kilotex is the mass in grams of one metre of material, 1000 tex. It is used for heavy strands such as slivers, rovings and tows.
Symbol: ktex
Quantity: yarn count (linear density of yarns and fibres)
SI relation: 1 ktex = 0.001 kg/m (exact)
Derivation: 1 ktex = 1 g per metre = 1000 tex = 10⁻³ kg/m (exact)
Exact: yes, by definition
Typical uses
- Card and draw-frame sliver (about 3–5 ktex)
- Glass and carbon fibre rovings
- Tow for staple fibre production
