Abstract
A new method has been invented for introducing texture, crimp, or set twist into synthetic polymer yarns which eliminates the need to heat the yarns prior to the texturing step. It has been found that the heat generated in the drawing step of synthetic yarn manufacturing processes is sufficient to cause a twisted undrawn yarn to retain the twist permanently after being drawn. The mild heat treatment experienced by the fibers is highly uniform and produces textured yarns of exceptional uniformity, especially with respect to dyeability, as compared with textured yarns produced by known art processes.
