Definitions

  • the invention relates to a method for producing a crimped multicolored composite thread in a melt-spinning process from a plurality of extruded partial threads and to a melt-spinning device for carrying out the method.
  • the partial threads are swirled several times before they are crimped.
  • a so-called pre-interlacing takes place before the partial threads are stretched.
  • post-interlacing takes place, with the post-interlacing nozzles being controllable separately from one another for the separate interlacing of the filaments. In this way, different color effects can be realized in the composite thread, which leads to a mixed color or a multicolor on the composite thread.
  • a further aim of the invention is to further develop the generic method and the generic melt-spinning device in such a way that a plurality of composite threads with different properties can be produced.
  • this object is achieved by a method having the features of claim 1 and by a melt-spinning device having the features of claim 8 .
  • the invention has the particular advantage that individual treatment of the partial threads is possible in each treatment stage, particularly during pre-interlacing, post-interlacing and crimping.
  • the partial threads can be treated separately or together as a partial composite thread.
  • the premature merging of several partial threads into a partial composite thread creates new, previously unknown color patterns, which are ultimately noticeable in the composite thread through high color separations.
  • the colored filament bundles are first extruded separately and, after cooling, combined to form a partial thread. This is followed immediately by pre-intermingling of the individual partial threads or of a partial composite thread formed from a plurality of partial threads.
  • the partial threads and the partial composite thread are pre-interlaced independently of one another.
  • the partial threads and the partial composite thread are stretched. In this way, the filament bond created by the pre-interlacing is partially eliminated. Subsequent separate twirling of the individual partial threads or the partial composite thread made up of several partial threads makes it possible to set special color mixtures, which are then crimped when the individual threads and the partial thread are textured separately and result in the desired color effects of the composite thread when brought together.
  • the pre-intermingling nozzles and the post-intermingling nozzles and the texturing nozzles are designed in the melt-spinning device according to the invention in such a way that either a single partial thread or a partial composite thread formed from several partial threads can be treated. This allows a variety of yarn types without additional treatment units are produced with the melt spinning device according to the invention.
  • the flexibility for producing the multicolored composite thread can be further increased in that at least one process parameter for pre-interlacing the individual partial threads and/or the partial composite thread can be freely selected individually for each of the partial threads and/or the partial composite thread. It is thus possible to set the treatment air pressure as a process parameter for each of the partial threads or the partial composite thread. It is also possible to select a setting for the process parameter in which no turbulence occurs on the part thread in question.
  • a plurality of compressed air supply lines with separate compressed air adjusting means are assigned to the pre-intermingling nozzles of the pre-intermingling device, so that the pre-intermingling nozzles can be controlled independently of one another. It is thus possible to treat a partial thread, a partial composite thread or no thread at all in the pre-interlacing nozzles.
  • the post-interlacing nozzles of the post-interlacing device are also assigned several compressed air supply lines with separate compressed air adjusting means in such a way that the post-interlacing nozzles can be controlled independently of one another. In this way, different compressed air settings can also be implemented during the post-intermingling of the partial threads or partial composite threads.
  • the process variant offers a further possibility of producing special color effects on the composite thread, in which at least one process parameter for crimping the individual partial threads and/or or the partial composite thread can be freely selected individually for each of the partial threads and/or the partial composite threads.
  • the process parameter is formed essentially by the nature of the fluid that is used for conveying and plug formation during crimping.
  • both the temperature of the fluid and the pressure of the fluid that is fed to the texturing nozzles are preferably designed to be controllable.
  • the variant of the method is provided in which the partial threads of the partial composite thread are mechanically mixed before stretching. Compared to the turbulence, this results in elongated mixing zones of the filaments, which result in a particularly high color separation in a carpet produced from the composite thread in a subsequent post-interlacing.
  • the melt-spinning device has a mixing device for mechanically mixing a plurality of partial threads, which is arranged upstream of the stretching device.
  • the method according to the invention for producing a crimped multicolored composite thread and the melt-spinning device according to the invention have the particular advantage that a plurality of different carpet yarns can advantageously be produced in a single-stage process. So it is common in the prior art to use yarn effects with high color separation to be generated by a downstream secondary process. This can advantageously be omitted by the method according to the invention and the device according to the invention. Yarn effects in the composite thread with extremely high color separation can advantageously be produced in one process step. In addition, relatively high production speeds can be achieved.
  • the partial threads and/or the partial composite threads receive a final swirl after texturing and before being brought together to form the composite thread.
  • a final swirling device is arranged downstream of the crimping device in the yarn path.
  • the end-intermingling device could be arranged between godets and have a separate end-intermingling nozzle for each partial thread.

  • the vertical grain shown is an example. In principle, the devices can be arranged one below the other or next to one another.
  • the spinning device 1 is usually coupled with three extrusion devices in order to obtain three polymer melts of different colors.
  • the spinning device 1 has a spinning beam 1.2, which carries a plurality of spinning nozzles 1.1 on its underside.
  • the spinning beam 1.2 is designed to be heated.
  • Each of the spinnerets 1.1 is coupled via a separate melt feed 1.3 to several spinning pumps--not shown here.
  • a polymer melt can thus be extruded into a large number of filaments at each of the spinnerets 1.1.
  • the spinnerets 1.1 have a plurality of nozzle bores on their undersides.
  • a total of three spinnerets 1.1 are provided in order to extrude three differently colored filament bundles.

  • the filaments are preferably subjected to cooling air in the cooling device 2 .
  • the cooling air can be supplied radially from the inside to the outside, transversely or radially from the outside to the inside.
  • a preparation device 12 and several collecting thread guides 13 are assigned to the cooling device 2 .
  • the preparation device 12 has at least one wetting agent 12.1 in order to prepare the partial threads 9 together.
  • the preparation device 12 contains several wetting agents 12.1, so that each of the partial threads 9 can be wetted separately.

  • the pre-interlacing device 3 has a plurality of pre-interlacing nozzles 3.1, which are coupled to a compressed air source (not shown here) by separate compressed air lines 3.2 and separate compressed air adjusting means 3.3.
  • the pre-interlacing device 3 has a total of three separate pre-interlacing nozzles 3.1, so that each of the partial threads 9 could receive separate pre-interlacing in the pre-interlacing nozzles 3.1.
  • the pre-interlacing device 3 is followed by the stretching device 4, which has several godets 4.1 and 4.2 for stretching the partial threads 9.
  • the galettes 4.1 and 4.2 are preferably designed as galettes wrapped around several times, the galette jacket of which is preferably designed to be heatable.
  • the partial threads 9 can thus be thermally treated and stretched.
  • the design of the stretching device 4 is exemplary.
  • the stretching device 4 can also have several godets in order to stretch the partial threads 9 in several stages.
  • the stretching device 4 is followed by the post-intermingling device 5 in the thread path.
  • the post-intermingling device 5 has several post-intermingling nozzles 5.1, which are connected to a compressed air source, not shown here, by several compressed air supply lines 5.2 and several compressed air adjusting means 5.3.
  • the after-swirl nozzles 5.1 can be controlled separately, with the respective setting of the compressed air being freely selectable.
  • a separate post-intermingling nozzle 5.1 is also assigned to each partial thread.
  • the after-intermingling device 5 is followed by the crimping device 6.

  • Each of the texturing nozzles 6.1 is designed in two parts and has a conveying part and a compression part in order to compress a fed thread into a thread plug.
  • the filaments are deposited in arches and loops, resulting in a crimp.
  • the texturing nozzles 6.1 are connected to a fluid source (not shown here) with a plurality of supply lines 6.2 and a plurality of adjustment means 6.3.
  • the fluid can be each heated separately to each texturing nozzle 6.1 to a predetermined temperature by a plurality of heating means 6.4.
