Abstract

1424931 Polyester fibres TOYO BOSEKI KK [trading as TOYOBO CO Ltd] 14 Nov 1973 [14 Nov 1972 (2)] 52876/73 Heading B5B A polyester fibre having an intrinsic viscosity of 0À32-0À48, a tenacity of 3À5 to 5À0 g./d., a knot tenacity of not more than 3À0 g./d. and a ratio of tenacity/knot tenacity of not less than 1À5, is made by drawing at greater than 80‹ C. a filament having said intrinsic viscosity to a birefringence of not less than 0À17, the undrawn filament having a birefringence of 0À015 to 0À080. The fibre preferably contains not less than 85 mol. per cent of ethylene terephthalate units and has a denier of not more than 5. In the examples, filaments of polyethylene terephthalate homopolymer and isophthalate copolymers are spun at 240-280‹ C. at take up speeds of 2500-3200 m./min. to given undrawn tows having intrinsic viscosities of 0À37-0À42 and birefringence of 0À025-0À043 which are drawn at 2À8-3À2 times at temperatures of 90-180 to give fibres of birefringence 0À182- 0À203, tenacities of 3À6-4À6, knot tenacities of 1À8-2À5 and tenacity/knot tenacity ratios of 1À5-2À55.
