Textiles. Determination of twist in single spun yarns. Untwist/retwist method1 Scope This International Standard specifies a method for the determination of the direction of twist in single yarns and the amount of twist, in terms of turns per unit length, by the indirect untwist retwist method. This International Standard is applicable to single spun yarns. This International Standard is not applicable to: a) open end spun yarns; b) false twist and self twist yarns; c) air jet yarns; d) yarns that stretch more than 0,5 % when
