Embodiment Construction

[0019] The subject matter according to the invention is only schematically shown in the drawings and should therefore not be understood as being to scale. The individual components of the subject matter according to the invention are shown in the figures so that their structure can be clearly shown.

[0020] Figures 1a to 1c Three mutually perpendicular sections of a yarn heater 1 according to the invention are shown. The yarn heater 1 according to the invention has a heating zone 3 with a yarn channel 5 . A heating wall 7 arranged on the yarn channel 5 can be heated by a heating device 9 . The heating device 9 comprises, for example, a heating coil which can be heated by means of an electric current. The temperature of the heating wall 7 can be adjusted by means of a regulating module, not shown in the figure, for example by regulating the intensity of the current flowing through the heating coils. The yarn guides 11 , 12 are arranged in the yarn channel 5 . These threa...

Abstract

A yarn heater 1 is provided, in particular for a false twist texturing machine, comprising a heating zone 3 with a yarn channel 5, on which at least one heating wall 7 is arranged, a heating device 9 is provided for heating Said heating wall 7, arranges a yarn guide 11 in said yarn channel 5, wherein the yarn guide 11 is arranged such that the yarn course 13 predefined by the yarn guide 11 has a zigzag shape. This yarn heater is especially suitable for the false twist texturing process as a main heater for heating polyamide yarns.

Description

technical field [0001] The invention relates to a device (yarn heater) for heat treatment of synthetic fiber yarns, comprising: a heating zone, the heating zone has a yarn passage; a heating wall arranged on the yarn passage; a heater for heating the heating wall Heating device; yarn guide arranged in the yarn channel. And the invention also relates to the use of a yarn heater. Yarn heaters are especially used on false twist texturing machines. Background technique [0002] Texturing processes, especially false twist texturing, for filament yarns, especially multifilament yarns, are known prior art. Texturing processes are used to process plastic flat and smooth multifilament yarns into crimped structured yarns that have textile properties due to their bulky and bulky structure. For this purpose, the multifilament yarn is usually unwound from the bobbin, passed through the first yarn guide roller, then heated in a yarn heater (main heater), cooled on a cooling rail (cooli...
