  • the filament bundle is crimped after cooling by means of a crimping device.
  • the individual filaments of the filament bundle become loops and Arches deformed so that the thread formed from the filament bundle has a crimp having.
  • Such a change in shape of the filaments of the filament bundle To achieve the crimping device, for example, as a texturing nozzle form in which the filament bundle by means of a conveying medium is jammed into a thread plug. When the filament bundle hits the thread plugs thus create the desired loops and arches of the individual filaments.
  • the filament bundle is used to achieve the most stable crimp possible stirred by a hot medium and warmed at the same time, so that a plastic change in shape in the individual filaments of the filament bundle can take place.
  • the thread plug After the thread plug has cooled, it becomes by pulling it into a crimped thread, which is then transferred to a Coil is wound.
  • the intensity and stability of the thread's crimp is decisive here by changing the shape of the individual filaments, i.e. when using a Texturing nozzle, through the plug formation and through the thermal treatment of the thread plug. So in addition to temperature and pressure of the conveyor also the residence time of the thread plug during the thermal Treatment parameters that significantly influence the ripple result.
  • DE 196 13 177 describes a method and a device known in which the filaments of the filament bundle led to a thread plug before disintegration to the crimped thread by an extremely long Cooling section are performed.
