Definitions

  • German patent application 2,053,354 describes a method in which a hot yarn plug in a bar guide is cooled by blowing air through it.
  • the process is not very flexible; when the treatment temperature or the thread thickness changes, the friction behavior of the plug changes and the temperature profile is uneven.
  • the hot stopper is placed on moving screens or belts. Since the stopper is not guided laterally, it is wetted with a fine atomized liquid mist. The thread must be dried before winding. The stopper is often not released at the end but at weak points that do not have been sufficiently cooled. ,
  • the object of the invention is to develop an economical method for cooling a yarn stopper, in which a uniform cooling of the stopper is achieved and when the take-off results in a smooth thread run.
  • the object is achieved in that the plug is pushed through a cooling section with a rod guide, a closed liquid jet is directed onto the yarn plug within this area, and the yarn is deflected by the plug when it is drawn off.
  • the dry hot stopper is guided and held in the cooling section by at least 3 elastic rods. In this area it is struck by one or several cold closed liquid jets and cooled effectively and evenly over the entire cross-section.
  • the structure of the yarn stopper emerging from the cooling section is so uniform that when the thread is drawn off, the thread loosens at the end of the stopper and the stopper is not expanded due to internal defects. This guarantees that the thread runs smoothly.
  • the withdrawn, still wet thread is deflected sharply, whereby the liquid is thrown off by centrifugal forces; this means that it is not necessary to dry the thread separately. Because of the rod guide in the cooling section, the liquid does not need to be atomized, but can act as a jet on the stopper.
  • the yarn plug is moved through a cooling section with a rod guide which is not in contact with the hot upsetting part. This avoids heat transfer from the upsetting part to the cooling section and the method according to the invention is even more effective. It is necessary to provide at least 3 elastic rods that are only clamped on one side at the beginning of the cooling section to guide the plug in the cooling section. The rods help to ensure that the plug is only pulled out at its end.
  • the distance can be up to 5 times the diameter of the plug without the need for special guiding of the plug. At such a distance, the plug does not buckle when entering the cooling section.
  • the process is suitable for today's high take-off speeds.
  • the filament yarn can be drawn off at 2000 m / min and more when the thread is running smoothly.
  • the parameters on the texturing nozzle are adjusted so that the end of the uncooled plug moves in the running direction and that of the cooled plug against the running direction of the thread.
  • the liquid jet then always hits the end of the plug.
  • the filament yarn 1 is compressed in the texturing nozzle 2 and guided by starches 3, which are attached to the exit of the texturing device. It then enters the cooling section, which in this case is not directly connected to the texturing device.
  • the hot yarn plug is not guided in the gap 4; no disturbances were observed as a result.
  • the cooling section consists of a holder 5 on which 4 elastic rods 6 are fastened on one side. The area between the rods 6 is greater than / equal to the area of the compression part of the texturing nozzle.
  • the texturing device is set so that where there is no more liquid on the stopper, the stopper begins to dissolve.
  • the thread 9 is drawn off, it being sharply deflected by the roller 10; a practically dry fader can be wound up.
