摘要

PURPOSE: To obtain a polyester-based false twist yarn alternately having a difference between deeply dyed property and shallowly dyed property in the longitudinal direction of the yarn and having fancy effect capable of providing soft touch feeling and stretchability to a fabric obtained by weaving or knitting the yarns. ;CONSTITUTION: This false twist yarn has deeply dyed parts A and shallowly dyed parts B in the longitudinal direction of yarn obtained by applying false twisting to a polyester-based latent crimped yarn. A filament constituting the yarn is free from substantial fusion and thick and thin unevenness and has 80-300% stretching elongation ratio and 30-60% elastic degree of the elongation work.;COPYRIGHT: (C)1996,JPO
