Abstract

Spun polyester yarn having an elongation of 55-195% and sufficient torqueless latent crimp to provide a bulk of at least 8% when hot-drawn at 200 DEG C to an elongation of 30%, is draw-textured at above the second order transition temperature producing a drawn textured yarn of at least 250 denier and elongation 10- 45% which is substantially torque- free. Preferably the yarn is draw- textured to an elongation of 20-35% and the drawn yarn denier is preferably at least 350.
