摘要： This invention relates to a high speed false twisting and apparatus, and more particularly to a high speed false twisting method for twisting smoothly yarns at a yarn speed of at least 1,000 m/min and to a high speed false twisting apparatus for conducting smoothly the method. More definitely, when thermoplastic multifilament yarns are false-twisted, false twisting is made with a high number of false twists satisfying the following formula (1) to obtain high quality false-twisted yarns, false twisting is then made at a yarn speed satisfying the following formula (2) to obtain higher productivity and false twisting is further made with a short thread handling length satisfying the following formula (3) in order to obtain high twisting stability. Formula 1: T » 0,24/∑A, Formula 2: V » 1,30 x 10-3/∑A, Formula 3: L « 90/V, where T: number of false twists inserted per meter yarn (n times/m; n is the number of turns of twist), V: yarn speed of false twisting (m/sec), L: length of thread handling from roller for feeding yarn to false twisting zone to twister to which false twist is inserted (m). Symbol A represents the sectional area (m2) of the yarn which is obtained by dividing the size of the yarn (weight per unit length) by the yarn density (weight per unit volume). Furthermore, the false twisting machine of the present invention for practising the false-twisting method includes an apparatus which consists of a feed roller for supplying the yarns at least to the false twisting zone, a heater for bringing steam into direct contact with the yarns, a cooler for bringing water into direct contact with the yarns, a false twister and a delivery roller that are disposed in order named.
