Definitions

  • the invention relates to a method of manufacturing a friction wire by friction spinning. reinforcement for interlining or technical textiles.
  • Such threads are intended to be woven or to be incorporated into a textile base for example formed of a knitted fabric.
  • Document EP-A-0 428 430 describes a reinforcing thread comprising a core thread and coating fibers which are bonded around the core wire using a adhesive substance. The coating fibers then give relief to the wire, which allows it to hang in the texture and therefore prevents it from sliding.
  • This technique has the disadvantage of providing, beforehand or after the combination of the coating fibers on the core wire, a step specific deposit of an adhesive substance.
  • the invention therefore aims to remedy these drawbacks by proposing a method manufacturing a reinforcing thread which plans to use the spinning method friction to associate, in a single step, coating fibers to a core wire, said fibers which can then be bonded to the core wire by heating and the wire thus obtained having a satisfactory feel.
  • the individualization and association of fibers on the core thread can be made with perforated spinning drums with strong air intake (friction spinning process).
  • the core thread is formed from a monofilament thread or a multifilament thread.
  • the core wire further comprises a wire formed of fibers which is associated or juxtaposed with said monofilament yarn or multifilament.
  • a step of heating the reinforcing wire to a temperature between the melting temperature of hot melt fibers and that of high point fibers may be expected.
  • the reinforcing wire 1 comprises a core wire 2 and coating fibers 3, 4 deposited around said core wire 2 by a friction spinning technique.
  • the reinforcing thread 1 is woven and when the textile base is a knitted fabric, the reinforcing threads 1 are incorporated into the mesh system without participating in the formation thereof. According to destination of the textile base, they can be introduced in the weft direction and / or in the chain direction.
  • the core wire 2 is formed of a thread 5 which is generally monofilament but which can also be multifilament.
  • the core wire 2 is made of a synthetic or artificial material such as for example polyamide, polyester or viscose.
  • the core wire 2 further includes a wire 6 formed of staple fibers.
  • the two wires 5, 6 are for example juxtaposed parallel to each other. Alternatively, they can be associated, for example by winding or wrapping the wire 6 formed of fibers discontinuous on the wire 5. The association or the juxtaposition is carried out prior to feeding the spinning machine 7 with the core thread 2.
  • the function of the wire 6 formed of staple fibers is to promote the attachment coating fibers 3, 4 on the core wire 2.
  • the material forming the fibers of the wire 6 may be the same or different from that forming the wire 5.
  • the choice of the type of core wire 2 used depends on the applications targeted for the reinforcing wire 1.
  • the core wire 2 is in particular a wire of large titration, by example between 160 Dtex and 800 Dtex.
  • the coating fibers 3, 4 are formed from a mixture of hot-melt fibers 3 and fibers 4 with high melting point.
  • high melting point fibers is used to denote fibers which melt or degrade at a temperature above the temperature of fusion of hot-melt fibers 3.
  • the hot-melt fibers 3 have a melting point below 150 ° C, the melting point of fibers 4 with a high melting point being greater than 180 ° C.
  • the hot-melt fibers 3 can be formed from copolymers, for example based on copolyamides, copolyesters.
  • 4 high-melting fibers can be synthetic, for example formed from polyamide, polyester, or artificial, for example made of viscose or natural, for example made of cotton.
  • the hot-melt fibers 3 are fibers two-component, for example of the CoPA / PA-6 type with a melting point included between 135 ° C and 145 ° C.
  • the hot-melt fibers 3 and the fibers 4 with high melting point have generally a titration, identical or different, between 1 Dtex and 3.5 Dtex.
  • the hot-melt fibers 3 and the fibers 4 with high melting point are arranged simultaneously on the core thread 2 by means of a friction spinning machine 7.
  • the friction spinning technique is itself known, but we continue below, in relation to FIG. 1, its essential characteristics for the understanding of the invention.
  • a coil 8 on which the core wire 2 has been wound is provided to be able to feeding, along a first path, the spinning machine 7 with said core wire 2.
  • a wick 9 or ribbon which is formed of mixture of hot melt fibers 3 and high melting point fibers 4 is fed into the spinning machine 7 via rollers 10.
  • the spinning machine 7 is powered with four identical wicks 9.
  • the wick 9 is prepared in a conventional manner by working, carding and drawing the fibers 3, 4 making it up. Hot melt fibers 3 and the fibers 4 with high melting point are then distributed uniformly in the wick 9 so that they are arranged statistically on the core wire 2.
  • the spinning machine 7 has perforated spinning drums 11 in which the two paths meet so as to be fed simultaneously in core wire 2 and in coating fibers 3, 4.
  • the function of the drums 11 is, by their rotation, to individualize the fibers 3, 4 forming the wick 9 and placing said fibers 3, 4 individualized on the core 2.
  • individualized is used here to describe the condition of fibers 3, 4 by as opposed to fibers which have been twisted and constitute a thread or still as opposed to long filaments.
  • the reinforcing wire 1 formed from the core wire 2 on which the hot melt fibers 3 and fibers 4 with high melting point are arranged is wound on a reel 12.
  • the reinforcing wire 1 is then heated at a temperature between the melting temperature of the fibers 3 and that of fibers 4 with high melting point.
  • This step allows, by fusion of the hot-melt fibers 3, to ensure a bonding fibers 4 with a high melting point on the core wire 2.
  • the feel of the reinforcing wire 1 can be made satisfactory in view of its application.
  • the coating fibers 3, 4 are already formed of two materials of nature different.
  • the reinforcing wire 1 is first incorporated into the textile base by weaving or knitting techniques then the textile base is heated to a temperature between melting temperature of hot-melt fibers 3 and that of fibers 4 at high melting point so as to ensure bonding of fibers 4 with high melting point on the core 2.
  • the coating fibers 3, 4 have the function of giving relief to the reinforcing wire 1 which allows it to be hooked in the texture.
  • the reinforcing wires 1 have a diameter generally greater than ten hundredths of millimeter and the core wire can have great rigidity.
  • the proportion of hot-melt fibers 3 in the wick 9 is between 20% and 60% by weight.
  • Reinforcement wire 1 thus obtained with a titration of 970 Dtex including 44% of wire monofilament 5, 26% yarn 6 formed of staple fibers and 30% of fibers coating 3, 4.
