Embodiment Construction

[0040] figure 1 A first embodiment of the device according to the invention for carrying out the method according to the invention is shown schematically. To extrude a plurality of colored monofilament strands, the device has a plurality of spinnerets 4.1, 4.2 and 4.3. The spinnerets 4.1 , 4.2 and 4.3 are arranged on the underside of the heated spin beam 3 . In order to extrude a plurality of fine filaments which are each guided into filament bundles 13.1, 13.2 and 13.3, the spinnerets 4.1, 4.2 and 4.3 have spinnerets on their undersides which contain a plurality of spinneret holes . Such spinnerets are known and are therefore not described in more detail here.

[0041] In order to extrude the filaments, colored polymer melts are fed to the spinnerets 4.1, 4.2 and 4.3 respectively. For this reason, each spinneret 4.1, 4.2 and 4.3 is equipped with a spinning pump 2.1, 2.2 and 2.3 respectively, and the spinning pumps 2.1, 2.2 and 2.3 distribute the corresponding polymer melt...

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 invention relates to a method for producing a multicolor composite yarn according to the preamble of claim 1 and a device for carrying out the method according to the preamble of claim 10 . Background technique [0002] EP 1 035 238 A1 already discloses a method of this type and an apparatus of this type. [0003] In this known method and known device, in order to produce multicolored composite yarns, firstly a plurality of dyed polymer melts are produced parallel to each other and side by side, and these dyed polymer melts are passed through a plurality of independent spinnerets. The polymer melt is extruded into corresponding colored monofilament bundles. The monofilament bundle consists of a multitude of individual monofilament strands which are extruded through the spinneret holes of the spinneret to form an endless / continuous strand. After multiple processing steps of cooling and drawing, these bundles of colored monofilaments are converged ...
