Embodiment Construction

[0040] figure 1 A first embodiment of the device of the invention for performing the method of the invention is schematically shown. In order to extrude multiple colored monofilament bundles, the device has multiple spinnerets 4.1, 4.2 and 4.3. Spinnerets 4.1, 4.2 and 4.3 are arranged on the underside of the heated spinning box 3. In order to extrude a plurality of fine monofilaments respectively guided into monofilament bundles 13.1, 13.2 and 13.3, the spinnerets 4.1, 4.2 and 4.3 have spinnerets on their undersides, these spinnerets contain a plurality of spinneret holes . Such spinnerets are well-known, and therefore will not be described in more detail here.

[0041] In order to extrude the monofilaments, colored polymer melts are fed to the spinnerets 4.1, 4.2 and 4.3 respectively. To this end, each spinneret 4.1, 4.2, and 4.3 is equipped with a spinning pump 2.1, 2.2, and 2.3, respectively. The spinning pumps 2.1, 2.2, and 2.3 transfer the corresponding polymer melt throu...

Abstract

The invention relates to a method and a device for producing a multi-colored composite thread made of a plurality of extruded colored filament bundles. To this end, a plurality of different dyed polymer melts are generated and extruded in parallel through a plurality of spinnerets to form the colored filament bundles. The colored filament bundles are brought together as a mixed color to form the composite thread. In order to generate a color pattern or to correct the mixed color of the composite thread, according to the invention, the generation of the dyed polymer melts is modified during the extrusion of the filament bundle in order to modify the mixed color of the composite thread.

Description

Technical field [0001] The present invention relates to a method for manufacturing a multicolor composite yarn according to the preamble of claim 1 and a device for implementing the method according to the preamble of claim 10. Background technique [0002] EP 1 035 238 A1 has already disclosed this type of method and this type of equipment. [0003] In this known method and known equipment, in order to produce multi-color composite yarns, a variety of dyed polymer melts are first produced in parallel and side by side with each other, and these dyed polymer melts are processed through multiple independent spinnerets. The polymer melt is extruded into corresponding colored monofilament bundles. The monofilament bundle is composed of a large number of single monofilament strands, which are extruded into endless / continuous slivers through the orifices of the spinneret. After multiple processing steps of cooling and stretching, the colored monofilament bundles are converged into comp...
