Definitions

  • the invention relates to a method for producing smooth yarn from thermoplastic synthetic threads, in particular smooth polyester yarn, according to which the plastic yarn is fed to a take-off unit by means of a delivery unit, stretched between the delivery unit and take-off unit, heat-set and finally wound up.
  • Smooth yarns made of thermoplastic synthetic threads and especially polyester threads are spun from a plurality of filaments. These filaments are combined into a bundle of threads, prepared and wound up at high speed.
  • the flat yarn to be produced obtains its usage properties by stretching.
  • the plain yarn is usually fed to a second heated supply unit via a first supply unit and pre-drawn to a ratio of less than 1.1: 1.
  • the flat yarn is heated on the second heated feed unit, for polyester to about 85 ° C. From the second feed unit, the flat yarn is fed to a take-off unit via a heating plate, finally stretched and then wound up.
  • the smooth yarn is heat-set on the heating plate, namely the fixation of a boil-off shrink or a hot air shrink with a surface temperature between 130 ° C. and 170 ° C.
  • This multi-stage process is relatively complex, also in terms of the device.
  • EP-A 0 224 306 also discloses a process for spinning stretching polyester threads with a given viscosity, wherein the polyester threads are drawn between a delivery godet with at least one separating roller at a predetermined thread speed and a draw-off godet with separating roller at a predetermined end speed via a stretching pin and thereby stretched and then wound up. To stretch them, the polyester threads are guided around an unheated stretching pin with a wrap angle of less than 360 °.
  • the stretched polyester threads are then heat-set, and the heat-setting can also be carried out on the draw-off godet at temperatures between 110 ° C and 240 ° C. Stretching and heat setting take place here - as in the known multi-stage processes - practically in separate process steps one after the other.
  • the invention is based on the object of specifying a simple and inexpensive method for producing smooth yarn from thermoplastic synthetic threads, in particular of smooth polyester yarn, and to provide a device which is suitable for carrying out this method.
  • the plastic yarn is preferably at take-off speeds from 300 m / min to 1600 m / min, preferably from 600 m / min to 1000 m / min cold drawn, at room temperature. Furthermore, the invention provides that the plastic yarn is heat-set between 2% and 40% at a surface temperature of the draw-off unit between 90 ° C and 250 ° C depending on a boil-off shrinkage or hot air shrinkage to be achieved.
  • a polyester yarn is used as the plastic yarn, which is drawn from a bundle of undrawn oriented threads and in front of a spinneret with a pull-off speed of at least 2500 m / min, preferably from a polyester POY ( Partially Oriented Yarn) with a titer of 40 dtex to 600 dtex.
  • Its undrawn polyester yarn is expediently cold drawn with a birefringence of at least 0.023 and an elongation at break between 55% and 180%.
  • the invention also includes the production of only a smooth, cold-drawn filament thread made of polyester or polyester POY.
  • the invention further relates to a device which is particularly suitable for carrying out the claimed method and is distinguished by a simple and functional design.
  • this device has an unwinding spool, a supply unit, a take-off unit and a take-up spool.
  • the take-off mechanism can be heated or has a heatable surface for heat setting the plastic or polyester yarn, the heating temperature being adjustable.
  • the take-off unit can have a separating roller for the plastic or polyester yarn wrapping around the take-off mechanism can be assigned in order to simultaneously subject the plastic or polyester yarn to a temperature treatment by means of cold drawing in order to adjust the cooking shrinkage or the hot air shrinkage.
  • polyester-POY stands for a polyester thread with a titer of about 40 dtex to 6000 dtex, which was melt-spun at a speed of about 2500 m / min to 6000 m / min, preferably 2700 m / min to 4500 m / min.
  • the device has an unwinding spool 2, a delivery mechanism 3, a take-off mechanism 4 and a winding spool 5. Between the delivery unit 3 and the take-off unit 4, the polyester yarn 1 is cold drawn with a draft ratio greater than 1.1: 1.
  • the cold-drawn polyester yarn 1 is heat-set at the same time on the take-off unit 4.
  • the extractor 4 has a heatable surface.
  • the heating temperature is adjustable.
  • the take-off unit 4 is assigned a separating roller 6 for the polyester yarn 1 wrapping around the take-off unit 4.
