Definitions

  • the invention relates to a method for 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 delivery godet 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
  • US Pat. No. 2,289,232 discloses the use of a heated draw pin between a delivery godet and a draw draw godet for spinning stretching polyamide yarn.
  • the yarn is wound 360 ° or a multiple of it helically around the fixed drawing pin.
  • the object of the invention is to provide a method for single-stage and multi-end spinning draws, which enables the drawing point to be fixed on a drawing pin with a sufficiently high drawing ratio.
  • the aforementioned object is achieved in that the polyester threads are guided around an unheated stretching pin with a wrap angle ⁇ of less than 360 °.
  • the stretching point can be fixed on the stretching pin with wrap angles of less than 360 °.
  • the stretching point is also fixed on the stretching pin if the thread in front of the drawing pin has not yet reached the glass 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 90 ° C., preferably 150 to 180 ° C., on the surface of the draw-off godet.
  • the wrap angle ⁇ around the stretching pin can also be set by means of at least one deflection roller. It has been shown that in the case of thin stretching pins, the time required to set a temperature equilibrium is relatively short. The temperature equilibrium is reached within 30 s with a 8 mm stretching pin with a dtex l67 f 30 titer polyester thread. 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 into two or more polyester threads 3 from a polyester melt via a spin pack l in a known manner and guided 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 over a draw-off godet 10 and a separating roller 11.
  • the drawn polyester thread is finally wound up on a winding roll l2 at a speed of 3000 - 6000 m / min.
  • the polyester thread 3 leads 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 deflection roller 9 and a wrap angle ⁇ of the thread of 180 ° or more.
  • a polyethylene terephthalate with an intrinsic viscosity of 0.92 was used on the same spin-drawing machine and extruded into four threads of titre 140 f 30.
  • the following changes have been made compared to the previous examples: - Between the nozzle plate and cross air blowing each thread was passed through a 20 cm long tube heated to 300 ° C. - The speed of the delivery godet was 2900 m / min, that of the take-off godet 5800 m / min. - The temperature of the discharge godet was 230 ° C. - The drawing pin was wrapped at 90 ° C. - All other spinning and stretching conditions corresponded to those of the previous examples.
  • the threads obtained had the following properties: - strength 56 cN / tex - elongation 14.7% - thermal shrinkage l90 ° C 5.5%
  • the thread material was particularly suitable for technical applications as well as sewing thread.
  • the method according to the invention can also be used with the same advantages for other fiber-forming polymers such as polyamides, polypropylene or polyethylene.
