Abstract
1352624 Crimping yarns SNAM PROGETTI SpA 18 Oct 1971 [17 Oct 1970] 48440/71 Heading D1F In a crimping process, a strand as may be formed by combining multifilamentary yarns of synthetic e.g. nylon, filaments is fully drawn, crimped in a compression chamber and subjected to a vapour e.g. steam, or gas-vapour mixture at a temperature of 70-150‹C during or subsequent thereto and finally subjected to a controlled extension to reduce or eliminate "visible" crimp. The vapour may be saturated or superheated, provided from an outside source or generated by vapourising (e.g. by means of a hot gas) a liquid carried by the strand. As shown, yarns supplied from bobbins 1, 2, 3 pass through a collecting ring 4 to form a strand which is drawn by rollers 5 and 7 whilst passing over a heated plate 6. Drawn strand is fed by rollers 8 to a chamber 9 wherein it is crimped by compression against a pressure member 10, and a chamber 11 to which vapour is supplied, thence through tensioners 12, around advancing rollers 13, 14 through a drawing zone defined between rollers 15 and 17 and wherein it is heated by plate 16 before collection on a bobbin 18. The strand product may have a crimp frequency of 2-8 per centimeter, a "rate" (as defined in the description) of 5-25% and may be produced from strands of initial denier of 2600-7800 intended for carpet weaving.
