ABSTRACT:
A cohesive yarn having latent twist, which is recoverable by relaxation of the yarn in heat and moisture, is composed of crimped and entangled continuous thermoplastic filaments. It provides good tuft definition and a lustrous appearance in pile fabric. Production of the yarn by hot jet-entangling crimped filaments throughout the length of a yarn bundle and heat-setting latent twist in the yarn bundle while false-twisted with an air-torque jet is illustrated.
