Definitions

  • the present invention relates to a method and a device for spinning fiber yarns.
  • Yarn production can be performed on many spinning systems.
  • a special case of thread is found in core threads, in which a core thread is wrapped in a sheath of staple fibers. Processes for obtaining core yarns are described in particular in the patents of the United States of America No. 1373880, 2024156, 2210884, 2313058, 2504523, 2526523, 3017740 and 3038295.
  • core yarns can be carried out on numerous spinning systems commonly used for the manufacture of yarns from staple fibers.
  • threads with spun cores generally have the disadvantage of being limited in the speed of production to that of the machines used and therefore to the twisting system used.
  • Self-twisted core yarns are known from United States Patent No. 4033102.
  • An original embodiment of self-twisted core yarns is described in French patents FR-A 2 461 040.
  • the advantage of this process is that it only requires unidirectional movements at constant speed.
  • its great drawback is that it imposes sudden and significant variations in torsion and therefore in tension which limit their efficiency at the level of production speed, and increase the risks of slipping of the covering fibers with respect to blade.
  • French patent FR-A 2 507 634 avoids these drawbacks and allows a high production speed without slipping of the covering fibers relative to the core and realizes after twisting a unidirectional twist of the plies. Its great drawback is that it requires the use of one or more continuous filaments serving as a vector for the covering fibers, which can be a drawback in the final product.
  • the present invention aims to allow the production of fiber yarns with or without a core with an extremely high production speed, obtained by consolidating the resistance of the fiber yarn, preferably when it has to withstand forces .
  • This object is achieved by a process of spinning a yarn of fibers according to which one stretches at least two wicks of fibers between the points of supply of this wick and pairs of stretching cylinders; the strands formed by each wick of fibers are twisted by a torsion member, in particular a friction member; they are brought together at the same point of convergence; the strands are wound; the yarn formed from the assembled strands is twisted on a twisting loom, the strands are spooled, characterized in that during twisting, the strands are given a false twist between the point of unwinding the yarn on the spool and the point of torsional grip.
  • the yarn is twisted on a conventional twisting loom, for example with a slider or double twist or double step loom to give the final twist.
  • At least two wicks of fibers are stretched separately between supply points and pairs of stretching cylinders; the strands formed at the same point of a torsion member are made to converge; the strands formed are passed through a pair of delivery cylinders; we reel. Then, the yarn is put on a twisting loom and a resistance of the yarn is ensured between the point of unwinding of the yarn on the spool and the point of taking torsion, by means of a false twist.
  • the wound wire is formed of at least two strands placed side by side having a low residual twist, possibly alternating, very low, sufficient to ensure cohesion of the covering fibers on the filament and insufficient to cause the assembly of the two strands by self-torsion in a regular and constant way.
  • the yarn after twisting is such that the fibers are all substantially parallel to each other in the axis of each strand with a variation equal to the very small residual twist existing in the yarn before twisting, but such that we know how to dissociate the two strands per twist.
  • a spinning process is carried out by stretching a wick of fibers 5a between a supply point 2a and a pair of stretching cylinders 4a.
  • the drawing system further comprises a pair of drawing sleeves 3a.
  • a strand of fibers 5b is stretched separately by a drawing system comprising a feed point, namely a pair of food rolls 2b, a pair of drawing sleeves 3b and a pair of drawing rolls 4b.
  • a continuous filament 6a, 6b is introduced upstream of the stretching cylinders 4a, 4b.
  • Two strands are therefore formed, each consisting of a wick of fibers and a filament.
  • the strands thus formed are twisted together by a wringer 7 and are guided by two guides 8 and 9.
  • the two strands then pass through a pair of cylinders 10 before being aspirated by a vacuum cleaner 13 before removing the continuous filaments for example by cutting, using a pair of manual scissors, upstream of the stretching cylinders.
  • the continuous filaments thus cut are therefore brought by the vacuum cleaner 13 to the waste.
  • FIG. 2 shows the spinning device after cutting the filaments, when the fiber yarn is wound on a cylinder 11.
  • False twist devices are known. They can be rotary or operate by friction. They can be static and a simple winding on a rod can ensure a torsion by rolling upstream of the rod when one pulls on the wire, provided that the angle of the wire relative to the rod, the diameter of the rod according to that of the wire as well as the pitch of the wire on the rod and the coefficient of friction of the material of the rod, are judiciously chosen.
  • the example in Figure 3 is a device that achieves these requirements. It consists of a body 14 of light material which supports a rod 15 in the form of a semicircle on the upper part of the body 14.
  • FIG. 4 represents a section of a double twist twisting spindle in which the coil of wire 16 is placed on the pot 17 where it is centered thanks to the centering device 18.
  • the wire 19 is unwound in the process, leaving the reel passes through the eyelet 20 of the wire feeder 21.
  • the wire is then wound on the rod 15 which is supported by the body 14, itself fixed by any means not shown, on the coronelle 21.
  • the wire After having made a certain number of turns the wire enters the body of the extension 22 where it will receive the first given twist turn by the torsion disc (not shown) and then pass between the pot 17 and the anti-balloon 23 where it receives the second twist before being wound on a coil not shown.
  • FIG. 5 A variant of the device is shown in Figure 5 where the wire is wound on a straight rod.
  • FIG. 6 Another variant of the device is shown in Figure 6 where the rod is spiraled into a cone.
