Abstract

1415966 Crimped polyester fibres TEIJIN Ltd 5 Nov 1973 [6 Nov 1972] 51323/73 Heading B5B Crimped polyester fibres are made by (1) drawing an undrawn tow of an ethylene terephthalate containing at least 85 mole per cent ethylene terephthalate units to 1À15-1À45 times the natural draw ratio (2) heat treating the drawn tow under tension at temperature T 1 (‹C) (3) feeding the heat-treated tow into a stuffer crimper to crimp the tow at a temperature of 80-130‹ C. and (4) heat-treating the crimped tow at a temperature T 2 (‹C) while allowing free shrinkiage of the tow and maintaining the packing density of the tow at at least 200 kg./m.<SP>3</SP>, T 1 and T 2 satisfying the relations T 1 is preferably > 180‹ C. and the tow has a total denier of 50,000-4,000,000. In step (1) drawing is effected at 60-100‹ C. in a steam or water bath or in one stage in water at 60-80‹ C. then in a second stage in water or steam at 80-100‹ C. optionally with the heat treatment step (2).
