Abstract

A process for making textile staple fibre from polytrimethylene terephthalate (PTT) which comprises: (a) melt extruding PTT polymer at 245 to 253 DEG C, (b) spinning the extruded PTT into yarn using at least one spinneret, (c) moving the spun yarn to a first takeup roll wherein the distance from the spinneret to the roll is from 16 to 20 feet, (d) cooling the spun yarn to less than 31 DEG C before it reaches the roll, (e) prior to the draw process, preconditioning the yarn under tension at a temperature of at least 60 DEG C, (f) drawing the yarn at a temperature of at least 60 DEG C, (g) allowing the drawn yarn to relax at a temperature of up to 190 DEG C, and (h) crimping the drawn yarn at a temperature of 70 to 120 DEG C, and decreasing the drawn yarn feed denier into the crimper by 10 to 60 percent by denier.
