Abstract

1330847 Crimped polyamide yarn IMPERIAL CHEMICAL INDUSTRIES Ltd 20 Aug 1971 [25 Aug 1970] 40857/70 Heading D1F A process for the continuous spinning, drawing and crimping of polyamide yarn is characterised in that a plurality of undrawn melt extruded filaments are cooled and subjected to the following process steps: (a) a first steaming treatment, (b) a second longer steaming treatment, (c) a drawing stage, and (d) a steam injection stuffer-box crimping treatment, and finally wound up. In a preferred embodiment, two sets of filaments 1, 2 issuing from spinnerets 3, 4 are fed to a steam conditioner 5. The filaments are converged to one bundle at guide 5a and advanced by feed and idler rolls 7, 8 to a steam treatment chamber 13. A spinning finish consisting of oil and water, may be applied at 6 between the guide 5a and the rolls 7, 8. In the steam treatment chamber 13, the yarn passes several times round rollers 11, 12 while steam, which may be saturated or superheated to 105‹C, is injected via ports 14, 15 and 16. The yarn is preferably maintained at at least 55‹C and the moisture content raised to at least 9% while the yarn is in the steam chamber 13. The dwell period of the yarn in the chamber 13 is at least 5 seconds. After leaving the chamber 13 the yarn is forwarded via rolls 17, 18 to draw rolls 20, 21, the draw being localised at snubbing pin 19. The drawn yarn is then fed to a steam injection stuffer-box crimper 22 and then fed via rolls 24, 25 to a wind-up mechanism 27. The yarn is preferably cooled and tensioned by an air jet at 23. In a preferred embodiment, the crimped yarn is passed through an intermingling jet 26 and wound up without twist.
