Definitions

  • the present invention relates to a textile yarn of the type comprising two twisted components spun in a single pass by the technique known as free fibers, or open-end whose characteristics make it suitable for use as a high performance sewing thread.
  • the spinning with free fibers using a turbine or rotor rotating at high speed is now perfectly known and controlled.
  • the fibers, in the form of an incoming wick, are individualized by the action of a breaker and projected inside the rotor; the produced wire acquires its twist thanks to the rotation of the rotor.
  • the progress made by this new technique compared to ring spinning knew limits, in particular as regards the use of the yarns obtained, taking into account the fact that they were necessarily one-end yarns.
  • Recently a manufacturer has modified its released fiber material in order to obtain in a single operation a wire comprising two twisted components.
  • the main modification consists in passing a second component through the rotating rotor, while the rotor is itself supplied by fibers coming from an incoming wick: the wire forming in the rotor and the second component are wound. around each other at each rotor turn.
  • the output speed of the product wire is slightly different from the supply speed of the second component: the latter is 4% (four percent) higher than the former.
  • the invention relates firstly to a high-performance sewing thread obtained on spinning material with released fibers, of the type comprising two components, one based on fibers, the second based on high-tenacity multi-strand filament, the proportion of filament relative to the whole of the yarn being between thirty and fifty five percent and characterized in that the fibrous component has a twist at least ten percent greater than the twist usually given to yarns with released fibers.
  • the invention also relates to a method for manufacturing a high performance sewing thread from a spinning material with free fibers, the thread being of the two-component type, one based on fibers, the second on high tenacity multi-strand filament base, and in which the filament feeding speed is equal to or more than three percent greater than the speed of drawing of the twisted yarn itself and the process is characterized in that the rotational speed of the rotor is adjusted so as to produce a twist in the fibrous component at least 10% greater than the twist usually given to threads with released fibers.
  • torsion it is usual to apply in spinning with free fibers a coefficient of torsion a of 115, for a fineness of polyester fibers of 1.3 dtex. In the yarn of the invention, this coefficient for the same fineness of fibers will be of the order of or greater than 130 for the yarn of fibers constituting the first component.
  • the thread is suitable for use as a sewing thread. Its dynamometric resistance, its elongation at break, its elongation / recovery, its dimensional stability are compatible with the requirements sought. What is more, and quite remarkably, the two components of the wire behave vis-a-vis the break as a unitary element; their individual resistance is added and a single rupture is observed and not in two stages, first that of the less resistant fibrous component then that of the filamentary component after elongation thereof.
  • the twist of the fibrous component is a Z twist and the twist of the two components together is also a Z twist.
  • traditional sewing thread material composed of two twisted components, it is accepted that the twist of the twist must necessarily be the reverse of the twist of the unitary components. It is therefore all the more surprising that the thread according to the invention has, despite this feature, all the characteristics of a high sewing thread. performance.
  • the compound yarn 1 according to the invention is composed on the one hand of fibers and of a high-tenacity multi-strand filament 3.
  • the photo (figurel) is an enlargement x 35 of a part of a yarn of this type ; we see very clearly the two components which are twisted one on the other.
  • the unitary strands of the filament 3 are almost parallel to each other, the filament possibly, however, originally having a twist.
  • the fibers 2, for their part, have a twist which gives them their cohesion and which comes from the mode of production by the rotation of the rotor.
  • the high tenacity multi-strand filament 3 is based on polyester, its tenacity is 68 mN / dtex; in the example described it is a filament of 220 dtex.
  • the fibers 2 are also polyester fibers, with a fineness of 1.3 dtex.
  • Fiber yarn 2 has a twist of 700 turns per meter, which corresponds to a twist coefficient a of 140.
  • the yarn 1 is obtained on the spinning installation with released fibers which comprises on the one hand the fiber treatment part 2 and on the other hand the assembly part of the filament 3 with the fibrous component 4 produced by the rotor 5
  • the incoming wick 6, making 3100 tex is fed by the delivery roller 7 and the pressing member 8, the fibers 2 are taken from the wick 6 by the breaker 9 and projected into the groove. 10 of rotor 5, which rotates at a speed of 40,000 revolutions per minute.
  • the high-tenacity filament 3 is fed by two delivery cylinders 11 rotating at a speed V ′ then, introduced into the rotor 5 through a channel 12 which opens into the axis of the rotor in the immediate vicinity of the yarn extraction nozzle.
  • the output delivery rollers 13 of the wire 1 extract, at a speed V, a wire 1 composed of the two components, fibrous 2 and filamentary 3, twisted together under the action of the displacement of the fibrous component 4 inside the rotor 5 around the filamentary component 3.
  • the filament supply speed is 2% (two percent) higher than the exit speed of the plied yarn 1.
  • the yarn 1 obtained at a titer of 62.2 tex which is distributed at the rate of 39.8 tex in fibers 2 and 22 tex in filament; which corresponds to a proportion of 64% of fibers and 36% of filament.
  • Thread 1 after having undergone a finishing treatment (sizing) for the use of the sewing thread, has been successfully tested on very diverse sewing machines representing all of the operations encountered in tailoring. Its machinability is therefore entirely satisfactory, as is the behavior in use of the article sewn with such a thread, both in the dry wash and in the wet.
  • the invention is not limited to the example described above. We can in particular vary the material entering the components, fibrous and filamentary, as well as their fineness, while respecting the proportions of each component and the twist of the fibrous component, characteristics of the invention. Furthermore, even if the thread of the invention is specially adapted for sewing thread use thanks to its particular characteristics, its use is not limited to this precise field.
  • the invention also relates to a process for manufacturing the thread described above and suitable for use as a sewing thread, said thread being produced from a spinning material with released fibers, and being of the two-component type, the one based on fibers (2), the second based on high-tenacity multi-strand filament (3), and the method is characterized in that the speed of feeding of the filament (3) is equal to or at most greater than three percent at the rate of take-up of the plied yarn (1) itself, and in that the rotational speed of the rotor is adjusted so as to produce a twist in the fibrous component at least 10% greater than the twist usually given to loose fibers.
  • the speed of rotation of the rotor is adjusted so that the coefficient of torsion a of the fibrous component is greater than 130.
