Abstract
PURPOSE: To obtain high twist-like bulky filament yarns having improved knitting and weaving properties with productivity twice that of the conventional false twisting step at a low cost according to a rational method, by draw false twisting undrawn thermoplastic synthetic filament yarns at a specific draw ratio.
CONSTITUTION: Undrawn thermoplastic synthetic filament yarns are draw false twisted at a drawn ratio of 0.65 or less of the maximum draw ratio in the draw false twisting. According to the method, alternate S - and Z - twisted yarns which are not untwisted are obtained at a somewhat higher preset temperature than the ordinary false twisting one relatively easily. The slight heat deterioration permits the high elongation of textured yarns. High - speed texturing is possible because of low draw ratio and ready absorption of variation in tension, thus providing productivity about twice that of ordinary false twisting of drawn yarns.
