Definitions

  • the invention relates to a false twist texturing machine for texturing a variety of thermoplastic threads and a method for manufacturing of a textured thread.

  • a swirl nozzle is arranged.
  • a false twist texturing machine is known from EP 0 532 458 B1, in which a thread is fed to a falling twist zone.
  • the false twist zone is a first heater and a false twist unit.
  • the false twist unit creates a twist that is opposite to the direction of the thread running. After the false twist unit, the thread becomes one led second heater.
  • the second heater is a blow nozzle downstream, which gives the yarn a wrong twist again, and in a direction that corresponds to the direction of the false twist unit generated swirl is opposite.
  • the present invention is based on the object of the type mentioned False twist texturing machine and to further develop the method in such a way that the thread can be wound up without twist regardless of the thread speed is.

In addition, leaves the counter-twist in the thread due to the higher elasticity simple way without essential energy supply and thus without essential Influencing the yarn properties such as bulk contribute. Because the counter-swirl immediately at the exit of the second heating section is generated, this can go undiminished in the heating device reproduce and be fixed in it.
