Definitions

  • the present invention relates to a false air torsion member, with improved efficiency.
  • Air false twist members have been known for a long time, for example, from United States Patent Nos. 4945718 and 4807431 where the wire passing through a cylindrical orifice receives false twist by jets of compressed air arriving at the periphery of this orifice through small tangential channels.
  • these false twist members include an inlet having a smaller diameter than that of the cylindrical orifice to have a suction facilitating the start of the wire.
  • the level of torsion depends on the air pressure, its flow, the diameters of the cylindrical orifice and the inlet as well as the coefficient of friction existing between the wire and the material of the cylindrical orifice.
  • the present invention aims to create a false torsion member of the type described above with an improved false torsion efficiency by modifying the coefficient of friction between the wire and the material of the cylindrical orifice, by injecting an air and liquid mixture. in small tangential channels without having disturbances due to the liquid element.
  • a false torsion member of the type described above into the cavity of which compressed air is injected to which an assistant lubricator a mist of metered liquid.
  • Said cavity also has an outlet where the excess liquid and air is sent through an oil separator filter which separates the liquid part which can be returned to the previous lubricator and the dry air part which can be used for 'other purposes.
  • the false torsion member consists of a body 1, crossed by a substantially cylindrical channel 2 and in which there is a cavity 3 located around the channel so as to communicate with the latter via channels. tangentials 4.
  • a passage 5 is provided which extends through the body 1 and opens into the cavity 3. This passage is connected to a lubricator 6, itself supplied with dry compressed air.
  • a suction nozzle (not shown) in the case of making fasciated wires.
  • the quantity of liquid to be supplied depends on the pressure and the flow rate of the compressed air, the dimensions of the orifice 2, the tangential channels, the spinning speed, the abrasion resistance of the fibers used ...
  • good results have been obtained by producing a 10 tex fasciated yarn composed of 100% high tenacity polyester fibers of 1.3 dtex fineness and 90 mm of average height at a speed of 300 m / min with a torsion member having an inlet diameter of 1.8 mm and an orifice diameter of 2.5 mm and a suction nozzle having a diameter of 5 mm.
  • the wire has an average resistance of 160 grams, or a tenacity of 16 g / tex.
