SOFT AND STRETCHABLE TEXTILE FABRICS MADE FROM POLYTRIMETHYLENE TEREPHTHALATE

摘要

A process of making a stretch fabric from polytrimethylene terephthalate whi ch comprises (a) spinning a polytrimethylene terephthalate polymer into a yarn with elongation of 60 to 150 %, (b) draw-texturing the yarn in a false-twist draw-texturing machine at a draw ratio of 1.02 to 1.6, and a yarn temperatur e of 120 to 160 ~C, and (c) heat setting the draw-textured yarn at a yarn temperature of 70 to 130 ~C.
