Definitions

  • the invention relates to a method for crimping a multifilament yarn according to the preamble of claim 1 and to an apparatus for carrying out the method according to the preamble of claim 8.
  • the multifilament thread is puffed up to form a thread plug.
  • the filaments of the thread are preferably conveyed by a hot fluid and deformed on the surface of the yarn plug to loops and bows.
  • the yarn plug is thermally treated. In the event that the thread plug formation already takes place by means of a hot fluid, the thus heated yarn plug is then cooled.
  • the yarn plug is guided on the circumference of a treatment drum.
  • the treatment drum is rotationally driven, so that the residence time for cooling the yarn plug is determined essentially by the peripheral speed of the treatment drum on the one hand and on the other hand by the degree of wrap of the yarn plug on the circumference of the treatment drum. Since the peripheral speed of the treatment drum is determined by process speeds and can only be changed to a limited extent, intensive cooling can only be achieved by appropriate wraps of the yarn stopper on the treatment drum.
  • Such entanglements have a negative effect, in particular when the thread stopper is broken up into a crimped thread, so that irregularities occur on the crimped thread which are particularly noticeable in a fluctuating thread tension when the crimped thread is pulled off.
  • Such thread tension fluctuations have a very negative effect, in particular in the after-treatment of the thread, for example by turbulence.
  • the object is achieved in that the thread is guided obliquely from the resolution of the yarn plug, which sets with increasing wrap of the thread on the circumference of the treatment drum, a growing axial distance between the thread and the yarn plug on the circumference of the treatment drum.
  • the sub-region of the filament strands placed in the inner region of the yarn plug are drawn more intensively in relation to the subregions set in the outer region, which considerably facilitates the triggering of possible individual overlapping points between the individual wraps of the yarn plug on the circumference of the treatment drum.
  • the yarn plug can be evenly transferred into the crimped yarn.
  • the thread between the resolution area and a drain area is guided over a wrap around the circumference of the treatment drum, which includes at least a circumferential angle of 45 °.
  • this makes it possible to realize only the thread tension forces which are only minimal for the yarn thread break-up compared to the thread tension forces required for the aftertreatment.
  • no significant tensile force acting on the thread is desired in the area of dissolution of the yarn plug.
  • the yarn tension required for the aftertreatment of the crimped yarn could be at a value of 100 cN.
  • the aftertreatment has proven particularly useful when the crimped yarn is vortexed before winding to a coil and after the treatment of the treatment drum by means of a swirling device.

  • the process variant has proven particularly useful in which the yarn plug is supported for storage on the periphery of the treatment drum by a conveyor, wherein the conveyor and the treatment drum independently driven become.
  • the density and guiding speed of the yarn plug can thus be adjusted on the one hand by the conveying means and on the other by the treatment drum.
  • a device according to the features of claim 8 is proposed.
  • the underlying object is achieved thereby according to the invention that means for guiding the crimped yarn are provided obliquely from the resolution of the yarn plug on the circumference of the treatment drum, the increasing axial distance between the thread and the.

  • the pull-off groove is arranged axially offset from the guideway receiving the thread stopper on the circumference of the treatment drum, so that a curled thread led obliquely out of the release area of the yarn plug can be introduced directly into the pull-off groove. This results in very stable and reproducible operating conditions and thread guides on the circumference of the treatment drum in the resolution of the yarn plug.
  • the formation of the device according to the invention has proven to be advantageous in which a diameter step is formed on the circumference of the treatment drum between the take-off and the guideway.

  • a wrap of the crimped yarn in the take-off groove can be realized, which preferably includes at least a circumferential angle of 45 ° at the periphery of the treatment drum.
  • the development of the device according to the invention is preferably used, in which between the texturing agent and the treatment drum, a supply means is arranged to ensure the smoothest possible transition of the yarn plug of the Texturing to the scope of the treatment drum to receive.
  • a supply means is arranged between the texturing agent and the treatment drum, to ensure the smoothest possible transition of the yarn plug of the Texturing to the scope of the treatment drum to receive.
