Definitions

  • This invention relates to a method and apparatus for the production of textured textile yarns.
  • I contribute as an important aspect of my invention, a process for the manufacture of textured textile yarns by mutual temporary high-twisting of a number of yarns and heat-setting of the mechanical deformation in the high-twisted state, which is characterized in that the single yarns are separately led through a yarn forwarding device positoined upstream or in advance of their assembling point in the process direction, and then over the lateral faces of a guiding member forming at least one sharp edge running through the yarn assembling point.
  • the invention furthermore, concerns an apparatus for the execution of the process which is characterized in that, before the yarn assembling point, a yarn forwarding member for the separate introduction of the yarns is arranged "ice and that between this forwarding member and the yarn assembling point a guiding member having at least one sharp edge is stationarily arranged.
  • the guiding member may take the form of a wedge or consist of several wedgeshaped parts, the edges of which lie in the same plane and intersect at one point.
  • the guiding member may furthermore advantageously consist of a hard material with a low frictional resistance, e.g. highly polished steel, ceramic material, etc.
  • the yarns it is possible to assemble the yarns so that the filaments do not get intermingled with each other in such a way that they will remain attached to one another when being separated and that no lengths of yarn only partially untwisted and thus of less volume than the rest of the yarn will be formed in the separated yarn ends. Furthermore, according to my invention, a very quiet and steady running of the yarns to be assembled is obtained, and therefore a stationary assembling point may be obtained so that the maximum number of turns per meter may be achieved by high-twisting. Because of an increase of the torsional and compressive forces a more intensive texturization and a greater bulk may be produced in the yarn than in known methods of mutual false-twisting of several yarns.
  • the speed of the yarns and, consequently, the production of textured yarns may be considerably increased without increasing the number of turns of the twist imparter.
  • the process according to the present invention may be used equally well on conventional false-twisting machines or according to the so-called spindleless process, wherein two or more yarns coming from spools are mutually plytwisted along a certain length, submitted to heat-setting in this state and then separated by continuously separating and winding them on spools.
  • the process according to my invention is especially suitable for the texturization of endless yarns or filament bundles as well as of staple fibre yarns consisting of thermoplastic materials, especially polyamides (polyhexamethyleneadipamide, condensation products of epsilonaminocaproic acid or ll-arninounde-canoic acid), polyesters (polyethylene glycol terephthalate), materials on a vinyl basis (polyacrylonitrile) or polyolefines, furthermore, cellulose acetate as well as mixed spun yarns of thermoplastic fibres and non-thermoplastic natural fibres.
  • thermoplastic materials especially polyamides (polyhexamethyleneadipamide, condensation products of epsilonaminocaproic acid or ll-arninounde-canoic acid), polyesters (polyethylene glycol terephthalate), materials on a vinyl basis (polyacrylonitrile) or polyolefines, furthermore, cellulose acetate as well as mixed spun yarns of thermoplastic fibres and non-therm
  • FIG. 1 schematically shows a device in accordance with my invention for assembling two yarns
  • FIG. 2 is similar to FIG. 1 but illustrates a device for assembling four yarns
  • FIG. 3 shows a lateral section of the latter device
  • Tables III and IV show examples of the assembling of four yarns according to FIGS. 2 to 4, whereby, in examples according to Tables I and III the yarns are temporarily mutually ply-twisted by means of a false-twisting device, whereas in the examples according to Tables II and IV, a temporary ply-twisting is effected according to the spindleless process.
  • FIG. 4 shows perspectively the guiding member for the I claim:
  • the yarns 1 and 2 coming from delivery spools are led through a pair of rollers 3, 4 serving as forwarding means and thereupon reach a stationary wedge 5 consisting of polished steel, for example, each yarn running over a lateral face of the latter.
  • a stationary wedge 5 consisting of polished steel, for example, each yarn running over a lateral face of the latter.
  • an assembling point 6 On the downstream edge of the wedge 5 is an assembling point 6 at which the yarns 1 and 2 come together and are mutually ply-twisted along the distance between that point and point 7.
  • the twister is positioned at point 7 and in application of the spindleless process a yarn separating device, as it is e.g. described in US. applications Ser. Nos. 331,568, 377,845, and 377,911, is positioned at point 7.
  • a heating device 8 is provided, by means of which the highly plytwisted yarns are temporarily brought into a plastic state, whereupon the setting of the spiral-like deformation takes place by resolidifying of the material downstream of the heater.
  • FIGS. 2-4 four yarns 9, 1t), 11, 12 coming from delivery spools (not shown) are led through a pair of rollers 3, 4 at a certain mutual distance, and thereafter over the yarn guiding member 13, which consists of two intersecting wedge-shaped parts 14, 15 and the edges 1d, 17 of which are situated perpendicularly to each other in the same plane and intersect each other at point 18.
  • the ply-twisted yarns thereafter pass through the heating device 8 and are again separated at point 7.
  • Tables I and II show examples for the asset hly of two yarns ll.
  • An improved process for the production of textured textile yarns comprising: mutually temporarily highly twisting a number of yarns and heat setting the mechanical deformation of the yarns while in the highly twisted state, characterized by the step of leading individual yarns from a supply source separately over lateral surfaces of guide means converging at an assembly point at which the yarns to be mutually twisted are brought together.
