METHOD FOR PRODUCING CONJUGATED FALSE-TWISTED YARN, AND WOVEN OR KNITTED FABRIC INCLUDING CONJUGATED FALSE-TWISTED YARN OBTAINED BY THE METHOD

摘要

PROBLEM TO BE SOLVED: To provide a conjugated false-twisted yarn that can provide an excellent bulky feeling, stretchability and drape properties and can express a dense moire feeling when made into a woven or knitted fabric.;SOLUTION: The method for producing a polyester conjugated false-twisted yarn includes subjecting a polyester highly-oriented undrawn yarn and a polyester conjugated yarn that are in a paralleled state to a false twisting processing, in which the polyester conjugated yarn that is to be subjected to the false twisting processing has a crimp rate of 15-55%, and the false twisting processing is carried out under conditions of a false twisting heater temperature of 140-180°C and a draw ratio of 1.02-1.3 times.;COPYRIGHT: (C)2016,JPO&INPIT
