ABSTRACT:
A polyamide (preferably nylon 66) partially oriented feed yarn contains a small amount of branching agent and has an elongation between 45 and 150%. The feed yarn can be textured by the friction twist process to yield a textured yarn having crimp development similar to yarn textured by the much more expensive pin twist method.
