Definitions

  • the invention relates to a cooling device for a synthetic thread, in particular a twisted thread within a texturing zone according to the preamble of claim 1.
  • the multifilament yarns produced in a melt spinning process are crimped in a downstream process for textile purposes.
  • the further treatment of the synthetic threads is effected by means of texturing machines, which have a plurality of processing points in order to curl one thread in each processing point.
  • the crimping of the thread which is also referred to as so-called texturing, can be achieved by a false twist treatment.
  • a mechanical false twist is generated on the thread, which is thermally treated within a texturing zone.
  • the twisted yarn is heated to a temperature of about 200 ° C and then cooled again.
  • cooling devices are used, which are formed as a curved cooling rail.
  • the largest possible radii of curvature are used on the cooling rail in order to keep the contact friction between the twisted yarn and the surface of the cooling rail low.
  • Such cooling rails use only the ambient air to cool the thread. Therefore, the cooling devices such relatively long cooling sections, which usually leads to a multi-layered construction of the texturing machine.
  • cooling devices are known in which the cooling of the thread is intensified by means of a cooling liquid.
  • a generic cooling device is known, for example, from EP 0 403 098 A2.
  • the twisted thread is guided within the texturing zone through a cooling groove on the surface of a heat sink, which holds a cooling liquid for wetting the thread in the groove base.
  • the wetting on the thread promotes the friction behavior of the thread between the thread and the contact rail, so that a twist transfer is favored.
  • Due to the twisted thread structure however, penetration of the cooling liquid into the thread is problematic.
  • the false twist creates a momentum on the thread and makes it difficult in the thread to adhere cooling fluid, which is only carried along by the thread and is thrown off the thread when leaving the cooling groove. Inadequate cooling is achieved in particular in the case of larger yarn tents, so that in the case of the known cooling device the yarn is subsequently guided over a cooling rail for residual cooling.
  • Another object of the invention is to consume the introduced into the cooling groove cooling liquid as possible for cooling the yarn.
  • This object is achieved in accordance with the invention in that the cooling groove has a groove cross-section divided into several partial cross-sections, in which the groove walls are inclined in at least one of the partial cross-sections (guide cross section) parallel to one another or each with an opening angle of less than 15 °.
  • the invention is based on the finding that the inherent dynamics of the thread caused by the false twist hampers the application of the cooling liquid or the action of the cooling liquid. So a part of the coolant is thrown off the thread. Furthermore, the inherent dynamics of the thread, which are manifested essentially by rotations, lead to a transverse evasive movement. There is the possibility that the twisted thread moves up the groove flanks of the cooling groove and leaves the groove bottom.
  • the cooling groove has a groove cross-section which is subdivided into several partial cross sections, wherein the groove walls are designed to be inclined in at least one of the partial cross sections parallel to each other or in each case inclined at an angle smaller than 15 °.
  • one of the partial cross sections forms the groove bottom, wherein the groove flanks, each with a larger opening angle are designed inclined relative to the groove edges of the guide portion.
  • the development of the invention is particularly advantageous, in which one of the partial cross sections forms one end of the groove flanks, the groove flanks of the insertion cross section each inclined with a larger opening angle relative to the groove flanks of the base cross section are executed.
  • a funnel-shaped opening of the cooling groove can be realized in order to insert the thread in a simple manner at the beginning of a process can.
  • the development of the invention has proven particularly useful in which the base cross section and the guide cross section of the cooling groove together form a Colournuttiefe the cooling groove, which is greater than 50% of a total groove depth of the cooling groove.
  • the twisted thread can safely lead in the groove bottom of the cooling groove, with an intensive consumption of the cooling liquid for cooling the thread is possible.
  • the development of the invention is preferably carried out, in which the groove bottom of the cooling groove has a plurality of alternating longitudinal sections in the thread running direction, wherein one of the longitudinal sections forms a corrugated groove bottom with a plurality of guide webs and wherein another of the longitudinal sections a formed in the groove depth smooth groove bottom.
  • the corrugated groove bottom of one of the longitudinal sections can be a continuous mitschleifen the yarn supplied to the coolant avoided.
  • the iffelung in the groove base is suitable to strip the adhering to the thread unevaporated coolant liquid residues and to keep in the cooling groove.
  • the thread can be evenly wetted over a longer distance, so that the generated cooling effects are intensified.

  • the length of the cooling groove is generally selected depending on the respective thread to be cooled and its yarn denier. For example, threads with relatively large thread tedders require relatively long cooling grooves.
  • the development of the invention is preferably carried out in which the longitudinal sections with grooved groove bottom and the longitudinal sections with smooth groove bottom each extend over a partial length of the cooling groove in the range of 10 mm to 40 mm ,

  • the groove base of the cooling groove on the heat sink is preferably designed such that the thread can be guided in the thread running direction on a guideway with a radius in the range of 300 mm to 1000 mm.
