Definitions

  • the subject of the present invention is a method and a device for spinning fiber yarns, optionally comprising at least one core.
  • 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 Nos. 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.
  • the threads with spun cores generally have the disadvantage of being limited in the speed of production to that of the machines employed 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 No. 7918173 and 7913995.
  • the advantage of this process is to require only 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 n ° 8111642 avoids these drawbacks and allows a high production speed without slipping of the covering fibers relative to the core and achieves after twisting a unidirectional twist of the ply. Its great drawback is that it requires the use of one or more continuous filaments acting as a carrier for the covering fibers, which can be a drawback in the final product.
  • the object of the present invention is to enable fiber yarns with or without cores to be obtained with an extremely high production speed, obtained by consolidating the resistance of the fiber yarn, preferably when it has to withstand forces. .
  • a process for spinning fiber yarns a process in which at least one strand of fibers is stretched between points of supply of these strands and pairs of stretching cylinders, upstream of which a continuous filament is introduced. and in accordance with the invention, the strands formed by each strand of fibers and each continuous filament are twisted by a torsion member preferably with friction, by making them converge at the same point situated upstream or downstream of the torsion.
  • the thread thus formed is passed through a pair of delivery cylinders placed after the torsion member, the thread is spooled on an appropriate support and the thread thus formed is twisted possibly by the strands on a twisting loom.
  • the cohesion of the wire is given between the point of twisting and between the point of unwinding of the wire:
  • the wire thus formed according to the invention is twisted on a conventional twisted loom, for example with a slider ring or with double twist or with a double step to give the final twist.
  • the cohesion is given to the yarn by sizing the fibers, namely by adding a cohesive product, to the fibers for example, before drawing the strands of fibers, in particular at the level of the preparation of the strands. , or more preferably after twisting the strands and before winding them.
  • the wire which is wound is such that there is no assembly twist which is avoided by adjusting the tension. If this assembly torsion exists, due to irregularities in the functioning of the torsion member linked to irregularities in the mass of the wire, it is a random twist, or alternating twist or non-regular self-twist. It is therefore neither regular in steps nor in intensity.
  • the invention makes it possible to avoid such an unwanted assembly twist of the wound wire.
  • the continuous filament or filaments are cut before winding.
  • the continuous filament or filaments are cut upstream of the stretching cylinders. This constitutes a mode of launching the manufacture which is in no way limiting and one can provide for other ways of proceeding.
  • At least two wicks of fibers are stretched separately between supply points and pairs of stretching cylinders, the continuous wires are supplied, they are introduced into said strands upstream of the different stretching cylinders and 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 and the continuous filaments are cut, upstream of the stretching cylinders, before the remaining assembly is wound.
  • the assembly formed by the fibers is then put on a twisting loom where a resistance of the wire is ensured between the point of unwinding of the wire on the spool and the point of taking torsion.
  • the cohesion means are placed between the point of unwinding the wire on the spool and the torsion point during twisting.
  • the wire which is wound has a very particular structure. Indeed, it 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 regular and constant self-twisting.
  • 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 as we know dissociate the two strands by untwisting.
  • 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 stretching system further comprises a pair of stretch sleeves 3a. in parallel, a strand of fibers 5b is stretched separately by a drawing system comprising a supply 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) 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.
  • a paraffinic sizing agent or a sizing agent containing colloidal silica may be advantageous to add to the fibers, during the preparation of the wicks, by sizing increasing this cohesion between the fibers.
  • a paraffinic sizing agent or a sizing agent containing colloidal silica may be advantageous to add to the fibers, during the preparation of the wicks, by sizing increasing this cohesion between the fibers.
  • a paraffinic sizing agent or a sizing agent containing colloidal silica This also has the effect of facilitating twisting.
  • friction torsion members which provide both a torsion component and a thread advancement component
  • 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 with respect 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 parade, 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 twist turn given by the disc torsion (not shown) to then pass between the pot 17 and the anti-balloon 23 where it receives the second turn of twist before being wound on a reel 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.
  • a yarn of fibers comprising at least two strands, which does not have any discontinuities, such as knots, splices or stops and which allows the production of spools of wire of significant weight, for example weighing at least 1 kg for fine threads, for example around 10 tex and spools of thread of at least 10 kg for coarse threads, for example for threads of around 1000 tex.
  • FIG. 8A Such a wire is shown in Figure 8A.
  • the fibers 28 are substantially much more parallel to each other than the fibers 29 of a thread of the prior art, all other things being equal.
