Title: Wet spinning process and product therefrom
IPC: D01D5/06
Filed: 1956-12-17
Abstract: <PICT:0841686/IV(a)/1> <PICT:0841686/IV(a)/2> <PICT:0841686/IV(a)/3> Apparatus for making a wet-spun slub yarn comprises a spinneret and its supply means, a spinning tube and means for forcing liquid therethrough, a baffle so placed that the filaments impinge on it after emerging from the spinning tube, and means for withdrawing the filaments from the baffle at a rate less than that at which they impinge thereon.  The slub yarn so made (Fig. 1) is a continuous filament yarn in which the filaments are individually looped upon themselves at intervals along their lengths, forming slubs randomly placed along the length of the yarn, and in which the loops forming the slubs do not adhere to each other.  Some or all of the filaments of the yarn may be of variable denier.  The yarns may be made of any wet-spun filament-forming material, but the process is described with special reference to regenerated cellulose.  As shown in Fig. 2, a viscose solution passed through filter 10 is extruded through spinneret 11 into tank 12 via spinning tube 13, in which a flow of both liquid is maintained by the difference in liquid levels of the tank 12 and enclosure 14. An eductor (not shown) may be fitted on the exit end of the tube to augment the flow of liquid.  The filaments strike a baffle 15 and pass round convergence guide 16 to feed wheel 17 and snubber roller 18.  Filaments are caused to leave the baffle at a lower rate than that at which they strike it by adjusting the ratio of feed wheel speed to linear bath velocity.  Yarn breakages may be reduced by using the apparatus shown in Fig. 3, in which filaments from a second spinneret 19 pass directly to the convergence guide 16, forming a second yarn which acts as a stress bearing element for the slub yarn.  Additional effects may be obtained by extruding a thick and thin yarn in the apparatus of Fig. 2, the variations in thickness being produced by known means, so obtaining a slub yarn superimposed on a thick and thin base yarn. A thick and thin yarn may also be used as the stress-bearing element in the apparatus of Fig. 3, to be combined with the slub yarn at the convergence guide.
