Polyhexamethylene adipamide feed yarn for false-twist texturing by combined draw-texturing processes is prepared by high-speed spinning under controlled conditions to have improved stability, low shrinkage, good tenacity and uniformity. The feed yarn has break elongation and birefringence values particularly suitable for draw-texturing.
