Definitions

  • the invention relates to a method for guiding and swirling a multifilament yarn during melt spinning according to the preamble of claim 1, and to an apparatus for carrying out the method according to the preamble of claim 9.
  • a generic method and a generic device are from the EP 0 940 485 A2 known.
  • a polymer melt is extruded through a spinneret having a plurality of nozzle bores into rope-shaped filaments. After cooling these very fine filament strands, the filaments are combined to form the synthetic thread.
  • the thread is treated, for example, by stretching, relaxing or curling.
  • the synthetic thread is wound up into a bobbin. In order to ensure a cohesion of the individual filaments in both the treatment and in the subsequent further processing in the thread, it is known to vortex the multifilament.
  • the thread closing required for further processing is performed by swirling a stretched between two godets piece of thread.
  • This can be the thread after expiry of a last galette lead directly to a take-up device.
  • the thread tension for swirling advantageously remains uninfluenced by the winding tension in the thread produced by the takeup device.
  • the swirling device is preferably placed in the last thread loop, in order to prevent the stretching tension from being influenced by the tension of the thread and to enable easy handling of the method.
  • FDY fully drawn yarns
  • Another object of the invention is to provide a method and apparatus for guiding and swirling a multifilament yarn in which the highest possible number of swirling knots can be produced reproducibly on the yarn.
  • the object is achieved by a method having the features of claim 1 and by a device having the features of claim 9.
  • the invention has the advantage, in particular in the production of fully drawn threads, that the thread tension for swirling remains independent of the drawing tension and remains largely independent of the winding tension.
  • a thread tension set on a piece of thread tensioned between the godets remains intact because the thread guided on the smooth peripheral areas of the leading sheaths can perform essentially no relative movement to the surface of the guide sheath.
  • a chucking length of the thread piece is determined by the leadership of the thread piece before swirling and after swirling by a smooth peripheral region, which leads due to their fixed length to a uniform Vcrwirbelungst with reproducible number of Verwirbelungsknoten.
  • the godets for guiding the thread can be formed both by godets with the same leadership coats or by godets with different diameter guide shells.
  • the godets for guiding the thread in a Mehrfachumschlingung advantageous by a galette executed with a larger diameter guide sheath and a godet with a smaller diameter guide sheath.
  • the godet with a smaller guide coat in professional circles is also referred to as a so-called overflow roll or Beilaufrolle.
  • the yarn tension is preferably adjusted by changing the peripheral speed of the guide casing, which is upstream of the swirling device. Due to the high adhesion between the smooth peripheral region of the guide shell, a changed circumferential speed leads directly to an increase or reduction of the thread tension in the thread piece between the two godets. To reduce the yarn tension during swirling, the circumferential speed of the guide casing is slightly increased. In order to obtain a higher yarn tension, the peripheral speed of the godet can be reduced accordingly.
  • the development of the invention is particularly preferably used, in which the thread is guided to the expiration of the godets on one of the smooth peripheral regions of the guide shells.
  • the smooth peripheral regions are each formed at a free end of the guide shells.
  • the guide shells are formed according to a preferred embodiment of the invention with a plurality of zone-shaped adjacent peripheral regions, wherein in addition to the smooth peripheral region in each case a non-smooth peripheral region with a larger Mittenrauhvvert of above 0.2 microns executed.
  • the thread in the last loop can advantageously be led to the outlet from the godet roll over a circumferentially reduced diameter area of the guide jacket. This reduces the circumferential speed of the downstream guide casing, which leads to a reduced thread tension.
  • This embodiment of the invention is particularly suitable for being able to wind threads with the lowest possible winding tension despite an upstream swirling.
  • the variant of the invention has proven in which the yarn is heated to a temperature of 80 ° C to 250 ° C before swirling.
  • the heating of the thread can be done in principle by any known type of yarn heating.
  • at least one of the guide shells is designed to be heatable by a heating device.
  • the swirling device preferably has a plurality of thread channels, which each form a distance in the range of 3 to 8 mm between them.
  • Each of the thread channels is advantageously associated with at least one arranged on the inlet side yarn guide.

  • the method according to the invention can be integrated into all known spinning processes such as, for example, for the production of POY threads, FDY threads, BCF threads or technical threads.
