Definitions

  • the present invention relates to a device for producing spinnable Synthetic yarn with a melt spinning device for the production of a filament yarn or Filament and a device for the creation of vulnerabilities in the Filament yarn or filament cable treatment device.
  • polyester is a synthetic fiber made of linear macromolecules with a chain at least 85% by weight of diol and terephthalic acid.
  • the first polyester was made in 1941 manufactured; it is known as polyethylene terephthalate (PET) and represents the quantitative most important synthetic fiber.
  • PET polyethylene terephthalate
  • the melt used in the melt spinning process becomes one Endless filament extruded and wound up after a stretching process or in the form of a Filament cord stretched, crimped and placed in cans.
  • the filament cables are for further processing with tear converting or stretch breaking devices intended. These are used to cut synthetic fibers from endless filaments to transfer spinnable nonwoven chemical fiber tapes from fibers of finite length.
  • This Work step involves several process stages in which the man-made fiber cables first stretched and then torn by further stretching. The stretching of the Chemical fiber cables are essentially made at different speeds driven roller pairs. There is a tape at the exit of the tear converter Staple fibers before that for further processing in a stretching machine, a
  • Tear converters require a very powerful motor, the speed of which must be kept constant. Both conditions affect the price of the rice converting equipment greatly increasing. To meet the requirements for strength and the exact speed of the drive of the tear converting device and thus also its It was proposed to reduce the price significantly, the treatment facility with a Device for creating weak points in filament yarn or filament cable equip. These weak points have the advantage that the later conversion of the tear requires significantly less energy and less demands on the Accuracy of the speed of the drive motor provides.
  • a preferred embodiment of the device according to the invention with a melt spinning device for the production of a filament yarn is characterized in that the Treatment device at least one stage for stretching the filament yarn and one Winding-up stage for this contains, and that said facility for the production of Weaknesses between the melt spinning device and the at least one stage Elongation of the filament yarn or immediately before the winding stage is arranged.
  • Such devices in which the starting product of the melt spinning device by a filament yarn is formed, are used to manufacture polyester filament yarn, namely either in a one-step or in a multi-step procedure.
  • End product is an on a bobbin wound polyester filament yarn, which has weak points and therefore, in a subsequent tear conversion process, more energy-efficient to a spinnable one Polyester yarn can be processed.
  • the treatment device preferably contains two stages for stretching the filament yarn, the device for creating weak points between the stages of stretching of the filament yarn is arranged.
  • Another preferred embodiment of the device according to the invention with a Melting spinning device for the production of a filament cable is characterized in that that the treatment device at least one step for stretching the filament cable and contains a stage for its crimping, and that said means for producing weak points between the melt spinning device and the at least one stage is arranged to stretch the filament cable.

  • the filament yarn 3 is fed to a treatment device 6 which has at least one, as shown contains two, expansion stages 7, 7 'for the expansion of the filament yarn 3.
  • the filament yarn is wound onto a bobbin 8 at the at least one stretching stage 7, 7 '.
  • the product wound on the bobbin 8 is a flat polyester filament yarn.
  • a preferred embodiment of the device according to the invention with a melt spinning device for the production of a filament yarn is characterized in that the Treatment device at least one stage for stretching the filament yarn and one Winding-up stage for this contains, and that said facility for the production of Weaknesses between the melt spinning device and the at least one stage Elongation of the filament yarn or immediately before the winding stage is arranged.
  • Such devices in which the starting product of the melt spinning device by a filament yarn is formed, are used to manufacture polyester filament yarn, namely either in a one-step or in a multi-step procedure.

  • the filament yarn 3 is fed to a treatment device 6 which has at least one, as shown contains two, expansion stages 7, 7 'for the expansion of the filament yarn 3.
  • the filament yarn is wound onto a bobbin 8 at the at least one stretching stage 7, 7 '.
  • the product wound on the bobbin 8 is a flat polyester filament yarn.
  • This known process can take place either continuously or discontinuously, the discontinuous process from the continuous process shown in the drawing distinguishes that between the spinning unit 2 and the treatment device 6 an interruption takes place in the manufacturing process.
  • the bobbin 8 then arrives the process shown in the drawing to a tear converter known Bauert (see for example WO-A-00/77283).

Following crimp level 11 the filament cable 5 is placed in a suitable container, such as a jug 12 filed or possibly wound up.
  • a suitable container such as a jug 12 filed or possibly wound up.
  • This known process can be continuous or run discontinuously, the discontinuous process being different from that in the drawing shown continuous differs in that the from the spinning unit 4th coming filament cable 5 stored in cans, temporarily stored and then the Jugs are removed, stretched, crimped and put down again.
  • the can 12 becomes a tear converting device brought, in which the filament cable 5 torn into staple fibers in the two crushing zones and in a solidification zone is solidified into a spinnable tape.
  • the spinning device shown has the main advantage that it has a final product Vulnerable provided filament yarn 3 or filament cable 5, which at subsequent stretch breaking for the production of staple fibers is no longer as strong needs to be stressed like a yarn or cable without weak spots, so that the Power consumption and dimensioning requirements Tear conversion device and to the constancy of the speed of their Drive motor can be significantly reduced. This also reduces the costs of the tear conversion device.
