  • Patent number: 11535955
    Abstract: The present invention relates to a device and to a method for producing a texturized filament or yarn, wherein at least one filament is guided into a draw device, is guided there by a pair of intake rollers towards at least two pairs of drafting system rollers and drawn by the same, downstream of which is disposed a texturizing device with a cooling drum. Downstream the texturizing device with the cooling drum is disposed at least one cooled drafting system roller, by which the filament, respectively the yarn is cooled to a temperature of 0° C. to 50° C.

  • Patent number: 11479884
    Abstract: A draw device into which at least two filaments are guided for producing a multi-coloured yarn from differently coloured filaments which consist of a plurality of endless filaments includes a pair of intake rollers for receiving the at least two filaments. Two pairs of drafting system rollers follow the intake rollers to draw the at least two filaments. A texturizing device comprising a texturizing nozzle with a cooling drum is disposed downstream of the two pairs of drafting system rollers to texturize the at least two filaments, wherein at least one yarn is formed from the filaments in the texturizing nozzle. At least one further nozzle is disposed exclusively upstream of the texturizing device in which each filament is separately interlaced. The filaments are drawn on at least one of the two pairs of drafting system rollers at a speed of at least 1,700 m/min.

  • Publication number: 20220251733
    Abstract: A process for production of a low-shrinkage aliphatic polyamide fibre, in which polyamide is extruded through a spinneret to form filaments, then cooled and combined to form at least one yarn. The at least one yarn is subjected to drawing between the spinneret and a pair of inlet rolls, then in a further multi-stage drawing step is subjected to 4-fold to 6-fold drawing by pairs of draw rolls. The pairs of draw rolls successively heat the yarn and at least the last pair of draw rolls has a temperature of 5° C. to 20° C. below the melting point of the yarn. The yarn is relaxed by from 6% to 10% in a subsequent at least three-stage relaxation zone and is kept in a temperature range of 5° C. to 15° C. below the melting point of the yarn, and is subsequently wound up on a reel device.

  • Patent number: 11286585
    Abstract: A process and an installation for producing a yarn in accordance with an airjet-spinning method. A carded fibre sliver is subjected to more than three-fold drawing without levelling at a carding machine and deposited in a can (C). At least nine fibre slivers are fed draftfree from cans (C) to a draw frame and subjected to at least 8.5-fold drawing to form a fibre sliver and deposited in a can (C1). The fibre sliver in the cans (C1) is then fed to a spinning station of an airjet-spinning machine.
