Crimped thermoplastic yarns are treated with solns or

摘要

Crimped yarns are produced from threads or thread bundles composed of thermoplastic polymers by conventional texturing processes, and during or after this processing are treated with solns. or dispersions of crosslinking materials. The threads are crimped by conventional processing methods, such as false-twisting methods. The present treatment gives crimped yarns with generally improved characteristics, such as better mechanical properties, higher elasticity, and a more durable crimpling.
