Definitions

  • the invention relates to a process for the single-stage spinning of two or more polyester threads with an intrinsic viscosity (IV) of 0.58 to 0.95, the polyester threads between a Uefergalette with at least one separating roller with a thread speed of 700 - 3000 m / min and a draw-off godet with a separating roller at a final speed of 3000 to 6000 m / min is drawn off via a drawing pin and thereby stretched and then wound up, and a device for carrying out the method.
  • IV intrinsic viscosity
  • the object of the invention is to provide a method for single-stage and multi-end spinning draws which enables the stretching point to be fixed on a stretching pin with a sufficiently high stretching ratio.
  • the aforementioned object is achieved in that the polyester threads are guided around an unheated stretching pin with a wrap angle ⁇ of more than 90 ° and less than 360 ° .
  • the stretching point can be fixed on the stretching pin with wrap angles of more than 90 ° and less than 360 ° .
  • the stretching point is fixed the drawing pin, even if the thread in front of the drawing pin has not yet reached the glass transition temperature.
  • the delivery godet has a surface temperature of 40 to 100 ° C, in particular 50 - 80 ° C.
  • a temperature of 110 to 240 ° C. in particular at 130 to 190 ° C., preferably 150 180 ° C., on the surface of the draw-off godet.
  • the wrap angle a around the stretching pin can also be set by means of at least one deflection roller. It has been shown that the time required to set a temperature equilibrium is relatively short with thin stretching pins. The temperature equilibrium is reached within 30 s with a stretching pin of 8 mm with a polyester thread with a titer of dtex 167 f 30. This time is usually shorter than the time required for the rest of the feeding.
  • the draw pin between the delivery godet and the draw-off godet. It has proven particularly advantageous to choose the diameter of the stretching pin from 4 to 20, in particular 5 to 10 mm. It has also been shown that the stretching pin can fix a plurality of threads separately in an arrangement provided perpendicularly or almost perpendicularly to the thread running direction. This has the advantage that the thread can be drawn in in a simple manner. It is advisable to combine a pulley with the straightening pin. It is advantageous to arrange the pulley in front of the stretching pin. In front of the stretching pin there is a lower thread speed and thread tension and thus less stress on the bearing of the deflection roller and thus a longer service life.
  • filaments 2, 2 ' are combined from a polyester melt via a spinning package I in a known manner to form two or more polyester threads 3 and passed through a device 4 which applies a spin finish 5.
  • the undrawn polyester thread 3 is now fed via a delivery godet 6 and a separating roller 7 to a stretching pin 8, to which a deflection roller 9 can be assigned.
  • a now stretched polyester thread 3 ' is guided from the stretching pin, which is wrapped more than 90 ° and less than 360 ° , over a draw-off godet 10 and a separating roller II.
  • the drawn polyester thread is finally wound up on a winding roll 12 at a speed of 3000-6000 m / min.
  • the polyester thread 3 runs over the delivery godet 6, the separating roller 7, the stretching pin 8 and is drawn off as stretched polyester thread 3 '.
  • FIG 3 shows the arrangement of the stretching pin 8 with the deflecting roller 9 and a wrap angle a of the thread of 180 ° or more.
  • the thread material was particularly suitable for technical applications as well as sewing thread.
  • the process according to the invention can also be used with the same advantages for other fiber-forming polymers such as polyamides, polypropylene or polyethylene.
