Abstract (en)

[origin: WO2018219751A1] The invention relates to a method for producing a crimped, multicolored composite thread in a melt spinning method and to a melt spinning apparatus for carrying out the method. According to the invention, a plurality of colored filament bundles are initially extruded separately, cooled and each combined into a partial thread. The partial threads are then separately pre-swirled and stretched individually or as a partial composite thread formed from a plurality of partial threads. A separate post-swirling of individual partial threads or of the partial composite thread and a separate crimping of the partial threads or of the partial composite thread then occurs. After the crimping, the partial threads and the partial composite thread are combined into a composite thread and wound into a coil. The melt spinning apparatus according to the invention has a pre-swirling apparatus having a plurality of swirling nozzles, a post-swirling device having a plurality of post-swirling nozzles and a crimping device having a plurality of texturing nozzles, wherein the nozzles are designed such that an individual partial thread or a partial composite thread formed from a plurality of partial threads can optionally be processed.
