Abstract
1346818 False-twisters; crimping yarns and fibres BAYER AG 19 April 1971 [19 Feb 1970] 22033/71 Headings D1D and DIF Frictional false-twisting apparatus comprises a wear-resistant, e.g. steel or polyurethane, tube 3 supported by bearings 2, rotatably driven by a belt 5 and formed with an annular bead 6 providing a highly polished edge 7, the opening diameter dR being less than the internal diameter dD of the tube. Synthetic, e.g. polyamide, polyester or polyacrylonitrile, yarn or filament(s) 8 having passed through a heating zone then passes through the tube 3 bearing only against the edge 7, Fig. 1 (not shown) or, as shown, bearing additionally on the outlet side against a similar edge 14 provided by a bead 13 screw-threadedly connected to the tube 3. At the one or both ends of the tube the yarn &c. 8 on each side of the edge 7, or edges 7 and 14, encloses an angle of more than 90‹, e.g. 100‹. The two edges roll and falsetwist the yarn &c. in opposite directions and the resultant accumulation and release of running twist in opposite directions in the zone between the edges is utilised to produce highly textured, bulked yarn rotated throughout its length alternately in S- and Z- directions.
