摘要： .[.A process for manufacturing a balanced synthetic yarn, i.e., a yarn having relatively no torque, including the steps of conventionally texturizing yarn formed of thermoplastic filaments, subjecting the yarn to a subsequent heat treatment, and twisting the yarn with a relatively low twist in the opposite direction from the twist imparted to the yarn during the texturizing process..]. .Iadd.A process for the preparation of low-torque textile yarn by imparting high twist to a thermo plastic yarn in one direction and heat setting, detwisting to impart an opposite torque to the yarn, applying a second heat setting to the yarn and then low twisting the yarn in the direction of the torque. .Iaddend.
