Definitions

  • the invention relates to a method for producing Polyester yarns according to the preamble of claim 1, according to which melt-spun polyester filaments behind a spinneret in a cooling zone cools at least solidification temperature and then for the purpose of stretching in a heating zone on a Temperature above the glass transition point or Freezing point warmed, and to generate the required Yield stress from a gaseous Medium is blown in counterflow and a device according to the preamble of claim 9.
  • US-A-47 43 504 is concerned with the manufacture of Plastic yarn, especially polyester yarn, based on a High speed melt spinning.
  • This Context is treated which plastic yarn specific properties regarding birefringence, Has viscosity, etc.
  • the threads and not the microfilaments are passed through a heating zone and in this to a temperature between the glass and Melting point heated.
  • This heating zone can be of various types be built u. a. also counter- or co-flowing Have air.
  • the Frictional resistance not increased.
  • Do not pre-stretch. It would actually be a stretching process even disadvantageous at this point, as a uniform heating of the filaments and consequently of the the filament bundled plastic thread over his entire cross section to a temperature above the Solidification point is hardly possible.
  • Secondary draw down zone refers to the Threads and not the microfilaments. Because in the quench zone following the spinneret are the individual filaments already spun or bundled into a yarn.
  • polyester filaments leave one here Spinning head, in connection to a cooling chamber or a To go through blow box. Directly after the The aforementioned filaments become one cooling chamber Bundles gathered and as a yarn a subsequent Subjected to heating. For this purpose the yarn goes through and not the polyester filaments a heating tube. Subsequently the yarn is drawn, with an aspect ratio between 1.3 and 1.7. This will set by means of two godets over which the yarn at a speed between 3500 to 5300 m / min running.
  • EP-B 0 491 012 (corresponding to the PCT / DE 91/00420) such a method has become known, at which microfilaments with a single titer ⁇ 1.0 dtex for final stretching at a take-off speed up to 8000 m / min through the heating zone and be blown in counterflow. After this known methods are fully stretched plastic threads generated without post-treatment, which becomes a special let fine and supple goods be processed.
  • the invention is based on the technical problem Method and an apparatus to indicate what Polyester yarns with optimized properties for technical Have uses made in a rational manner.
  • the invention further teaches that the amount of air and The temperature of the counterflow air can be set so that a thread stretch ⁇ 50%, preferably 30% to 40%, is achieved. Furthermore, the withdrawal speed of the Polyester filaments, the amount of air and the temperature of the Counterflow air can be adjusted so that a tensile strength the polyester filaments> 3.2 cN / dtex, preferably 3.4 cN / dtex to 4.5 cN / dtex. In addition, there is Possibility of the amount of air and the temperature of the counterflow air set so that a hot air shrinkage ⁇ 6% (at 177 ° C) is reached.
  • Polyester filaments following the counter current treatment continuously stretched so that a single step Manufacturing process is realized.
  • the post-stretched Polyester filaments may be before winding be subjected to a swirling and re-preparation.
  • the polyester filaments in a separate treatment stage be stretched, for example on one Stretching device such as draw twine or stretch winder.
  • the invention also relates to a device for producing polyester yarns from polyester filaments with a single denier from 1.0 dtex to 7.5 dtex according to the method described above, with at least one spinneret of a cooling zone downstream of the spinneret and of a countercurrent heating zone downstream of the cooling zone.
  • This device which is characterized by a particularly simple and functional design with a high production speed, is characterized in that the godets heated for the purpose of pre-stretching the polyester filaments with an air flow of 5 m 3 / h to 25 m 3 / h in countercurrent heating zone for the purpose of post-stretching with a godet temperature of 80 ° C to 250 ° C are subordinate that the godets can be driven at different speeds to set a predetermined stretching ratio, and that the godets one with a winding speed of 5000 m / min to 8000 m / min working rewinder for the post-stretched polyester filaments.
  • the single figure shows a device according to the invention for the production of fully oriented technical polyester yarns.
  • This is a spinning device 1 with an extruder 2 and a spinning beam provided as a spinneret 3.
  • the Extruder 2 supplies the spinneret 3 with polyester melt.
  • the starting product for the polyester melt is a polyester granulate in the viscosity range IV 0.60 - 1.10 dl / g.
  • On the spinneret 3 is followed by a reheater zone 4.
  • a cooling zone with blowing follows. To the cooling zone 5 is followed by a countercurrent heating zone 7, in the the unbundled polyester filaments 8 in countercurrent be blown. This is followed by a device for the preparation order 9 and thread bundling after Exit from the counterflow heating zone 7.
  • the counterflow heating zone 7 heatable godets 10 are arranged downstream.
  • the Godets 10 are at different speeds drivable.
  • the godet 10 is a winder 11 for the post-stretched polyester
  • the post-stretched polyester filaments 8 and the polyester yarns produced therefrom have the following properties: Elongation at break 6.5% to 12% tensile strenght 5 cN / dtex to 7.5 cN / dtex Shrink, hot air 177 ° C ⁇ 6.0%.
