Tex number
Also known as: tex count, yarn linear density
Universal weight numbering system for yarns: grams per 1000 metres; higher tex = coarser yarn.
Description
The Tex number is the internationally standardised direct weight numbering system for yarns, twists and threads (ISO 1144, ISO 2060). A yarn of tex 30 weighs 30 g per 1000 m; higher tex = coarser/heavier yarn, lower tex = finer/lighter. For very fine fibres the subunit decitex (dtex, g/10,000 m) is used, common for technical yarns in sportswear and tyre cord. Twists are written as combinations, e.g. tex 60/2 for a two-ply twist from tex 30. Conversions: tex = 1000/Nm (metric), tex = 590/Ne (English cotton), tex = denier/9 (chemical fibres). Sewing threads for workwear are typically between tex 20 (light business seams) and tex 60 (jeans, waistbands, webbing). Tex is the basis for many material specs in corporate wear and PPE procurement.
