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 crimp of the thread which is also referred to as so-called texturing, can be achieved by a so-called false twist treatment.
  • a mechanical false twist is generated on the yarn, which is thermally treated within a so-called 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 to the Contact friction between the twisted thread and the surface of the cooling rail to keep low.
  • Such cooling rails use only the ambient air to cool the thread. Therefore, such cooling devices require relatively long cooling distances, 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 for example from the EP 0 403 098 A2 known.
  • the twisted yarn 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 yarn in the groove base.
  • the wetting on the thread favors the friction behavior of the thread between the thread and the contact rail, so that a swirl transfer is favored.
  • Due to the twisted thread structure however, penetration of the cooling liquid into the thread is problematic.
  • the false twist generates a momentum and makes it difficult in the thread, the adhesion of cooling liquid, which is only carried along by the thread and 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 carry out the wetting of the thread with the least possible excess of residual cooling liquid.
  • the heat sink has at least one ceramic insert at a yarn inlet, which forms a corrugated groove bottom within the cooling groove and on the corrugated surface of the thread can be guided with contact, wherein the metering is associated with the ceramic insert.
  • the invention has the particular advantage that the cooling liquid within the cooling groove distributed over a wetting zone without being directly carried by the thread.
  • the thread is guided with contact on a ceramic insert, which forms a corrugated groove bottom within the cooling groove.
  • the thread can be guided over a plurality of support points, which limit the friction on the thread despite intensive contact and lead to no spin obstruction.
  • the grooves of the groove bottom, which are filled with cooling liquid, act particularly at the beginning occurring strong evaporation of the liquid on the thread and constantly renew the liquid application on the thread.
  • the supply of the cooling liquid is preferably carried out in an inlet zone of the groove bottom, which is arranged upstream of the corrugated groove base.
  • the metering opening opens in the inlet zone, which is traversed by the thread with contact or preferably without contact.
  • the development of the invention is preferably carried out for stable yarn guide, wherein the heat sink at a yarn outlet of the cooling groove at least one further ceramic insert having a corrugated groove base, wherein the cooling groove between the ceramic inserts has at least one guide portion with a smooth groove bottom.
  • the thread can also be performed at the yarn outlet with sufficient thread contact in the cooling groove without undue high yarn friction arise.
  • any liquid residues on the thread can be retained in the groove bottom. A dripping of liquid after leaving the cooling groove can thus be avoided.
  • the smooth groove bottom of the guide portion has a greater groove depth than the ceramic inserts with the grooved groove grounds.
  • the ceramic inserts each have a longitudinal section of the cooling groove, which ranges depending on the filament titer in the range of 10 mm to 60 mm.
  • such ceramic inserts can also be formed to several in the cooling groove at a distance from each other.
  • the ceramic inserts are preferably arranged on the heat sink to each other so that the groove bases in the yarn running direction have a guide curvature with a radius in the range of 300 mm to 1000 mm. This makes it possible to realize very compact texturing zones within texturing machines.
  • the structural design of the cooling groove on the heat sink can also be advantageously carried out segment-shaped, so that individualdenutabitese are alternately formed by ceramic inserts or material inserts, the ceramic inserts and material inserts are held together on a support.
  • the ceramic inserts form the guide sections of the cooling groove for the contact guidance of the thread and the material inserts in each case the guide sections with a smooth groove bottom for contactless guidance of the thread.
  • the development of the invention is particularly advantageous in which the heat sink is disposed within a housing between a yarn inlet and a yarn outlet and in which in the region of the yarn outlet a suction opening is formed in the housing, which can be connected to a suction device.
  • the thread guide within a texturing zone can be improved in particular by the development of the invention by the thread inlet of the housing an inlet yarn guide and the yarn outlet of the housing is assigned a AuslassfadenIZ.
  • the inlet and outlet angles, with which the thread enters the cooling groove and is led out can be adjusted particularly accurately and reproducibly.
