Abstract

The process concerns the fabrication of a smooth polyester yarn whereby the polyester yarn is cold-drawn between a pair of feed rollers and a take-up unit in a draw ratio of from 1.15 : 1 to 2.3 : 1 and heat set on the take-up unit. This is a simple and inexpensive way of combining single-stage cold-drawing with simultaneous heat-setting.
