Abstract
1290912 Finishing yarns IMPERIAL CHEMICAL INDUSTRIES Ltd 24 Dec 1969 [23 Sept 1969] 46828/69 Heading D1F Running filamentary yarn 1 of thermoplastic polymeric material is relaxed by being drawn from a supply by a fluid tensioning device supplied with unheated gas and then passed through a heating zone preferably at 180- 250‹C at a lower zero, or decreasing tension. The fluid tensioning device may comprise a guide tube 2 the exit of which has adjacent the exit tube 3 of a surrounding chamber 4 fed with unheated gas via an inlet 5. The forwarded yarn passes through a guide tube 7 rotatable by a pulley 15 and is laid in helices on the inner surface of a cylinder 8. Hot gas is expelled from a porous ring 11 at the foot of cylinder 8 and rises to heat the yarn in the relaxation zone. Slots 9 which may be adjustable in size are provided at the top of cylinder 8 to allow the hot gas to escape. In a further form, Fig. 2, not shown, the yarn is forwarded into the top of a chamber which tapers outwardly in a downward direction and is externally heated. The polymeric material may comprise a polyester, a polyamide, a polyolefine or a copolymer within or between these classes. The yarn may comprise conjugate filaments with components arranged side by side or in eccentric sheath-core fashion; alternatively the yarn may comprise filaments which have been assymetrically heated or cooled or have been false-twisted.
