Abstract: A method of manufacturing textured yarn comprises providing a crimped yarn composed of numerous crimped and entangled together thermoplastic synthetic fibers, partially removing some of the crimp from the crimped yarn, heating and pressing together the resulting partially crimped yarn to contact the fibers at their mutually intercrossed locations with sufficient pressure and at a sufficient temperature to effect permanent transverse deformation of the fibers at their contact points, and terminating the heating and pressing to obtain a textured yarn composed of numerous fibers having longitudinally and randomly spaced transverse deformities. The yarn is initially crimped by false twisting and steam setting, and some of the crimp is removed from the crimped yarn to remove from 75 to 95 percent of the crimp.
