This British Standard describes two methods of indicating the composition of yarns, whether single, folded, cabled or multiple wound. The designation comprises linear density indicated in the Tex System, number of filaments in filament yarns, direction and amount of twist, and number of folds.
This designation has not yet been extended to some special kinds of yarns, e.g. to fancy yarns, textured or bulked yarns or yarns produced by wrapping a textile, or non-textile material, round a core; nor does it deal with other features such as constituent fibres, after-treatment and type of package.
