Definitions

  • the present invention relates to an improved process, as well as to a device for its implementation, making it possible to produce in a simple and economical manner, at high speed, a new type of fiber yarn having a unidirectional twist along its length and without using ring winding systems and sliders.
  • discontinuous fibers into a multifilament core, for example by using a false twist system acting on the core thread, so that upstream of such a false twist member, the filaments are separated and open, the fibers being incorporated at this level and the thread resuming its initial twist and consequently trapping the fibers at the exit of the spindle from the false twist.
  • a false twist system acting on the core thread
  • the method according to the invention has great flexibility by the fact that it can be used both for obtaining regular threads and fancy threads having, for example, flame effects, plugs, buttons, etc.
  • the invention also relates to a device for implementing such a method, as well as the new type of yarn produced.
  • the method according to the invention is of the type according to which elementary parallel fibers are associated with a textile core, subjected to a false twist, said fibers being projected onto the core upstream of the false twist spindle , characterized in that in the projection zone of the fibers, the core is guided in a channel having an open face arranged opposite the projection zone of the elementary fibers and the surface of which is subjected to a current of fluid which tends to exert a tensile force on the end of the fibers.
  • the process according to the invention makes it possible to obtain perfectly regular threads, it can be easily adapted for obtaining fancy threads, by varying, for example, the speed of call of the thread and / or the ascent length of torsion upstream of the spindle and / or the flow of fibers projected onto the core.
  • the core is advantageously constituted by a continuous multifilament yarn, it can also be constituted by any other filiform textile element, for example by a spun of fibers with which a multifilament core can optionally be associated.
  • Figure 1 illustrates, side view, a working position of a machine allowing the implementation of the method according to the invention, that is to say allowing to produce at high speed, a yarn of fibers having a twist unidirectional.
  • This machine comprises, in known manner, a storage area (1) for multifilament yarns (2) coming from spools (3).
  • An intermediate deliverer (4) which could possibly be omitted, and which is constituted for example by a continuous shaft extending over the entire length of the machine and on which rollers or strips are supported, makes it possible to bring the wires ( 2) to the actual processing elements grouped together, for example, on a frame (5) arranged opposite the storage area (1).
  • an assembly is arranged, designated by the general reference (10) making it possible to project elementary fibers parallelized on the core wire (2).
  • the core wire (2) can be constituted by a continuous multifilament wire but other types of core wire could be used for the implementation of the invention. As shown in Figure 1 in dotted lines, it may be considered for use as core yarn a yarn of fibers made directly on the machine, for example by providing a drafting arrangement (18) for a lock of fibers (19). In this case, the deliverer (6) can consist of the last pair of stretching cylinders of said stretching train (18). Of course, such a fibrous core can also be associated with a continuous thread by bringing a multifilament thread (2) upstream of the deliverer (6).
  • the breaker (11) is supplied with a wick (17) having a titer of 30,000 decitex (Nm 0.3), based on cotton.
  • the draw of the wick (17) in the breaker (11) is set to 300.
  • the suction plate (12) disposed opposite the outlet (15) of the breaker (11) has a V-shaped slot, having a depth of 5 mm and an open part of 10 mm in width.
  • This plate (12) has a length of 5 cm and has 15 orifices (16) spaced regularly and each having a diameter of 1 mm.
  • the vacuum source (13) is adjusted so as to be able to create a suction of the order of 200 mm of water.
  • the plate (12) is arranged upstream of the spindle (7) so that the wire (2) comes to tangent with the bottom of the V-shaped slot.
  • a yarn of fibers consisting of a core, the elementary filaments of which are practically parallel to each other, said core being covered with a layer of fibers having a true twist.
  • Such a thread can be used for all conventional applications, such as weaving, knitting.
  • Example 1 is repeated, but the multifilament core (2) is introduced into a wick (19) drawn upstream of the cylinders (6) as shown in dotted lines in FIG. 1.
  • the wick (19) is based on wool and has a titer of 3000 decitex (Nm 3), the drawing carried out in (18) being 30 times.
