Definitions

  • the invention concerns a method for producing a multifilament composite thread in a melt spinning process according to the preamble of claim 1 , as well as a melt spinning device according to the preamble of claim 10 .
  • said yarns are normally generated from a bundle of fine extruded filament strands.
  • the filament strands combined within a filament bundle can then be pulled-off and drawn as a thread.
  • the composite thread therefore consists of at least two filament bundles, each having numerous filament strands, which, after the pulling-off and drawing, are combined to form the composite thread.
  • the filaments of the filament bundle can, thereby, be produced from an identical polymer material having the same additives, wherein the yarn effect is substantially based on the different treatments of the filament bundle.
  • composite threads can be generated with which the filaments exhibit different shrinking behaviors, in order, for example to obtain a type of crimping in further processing through the development of waves and loops.
  • the production of the filament bundle for a composite thread from a polymer material having different additives, such as different pigments, for example, is, however, also known.
  • the yarn effect in the composite thread is substantially established by the visual appearance.
  • the treatment of the filament bundle for forming the composite thread in this case is the same for both filament bundles. In this manner, for example, carpet yarn is produced with mixed colors, which are obtained through the combining of different colored filament bundles.
  • the preparation quantity lacking for an optimal further processing is applied in a second wetting.
  • the filament bundle is wetted with a predetermined partial quantity of a preparation fluid.
  • each of the filament bundles is to be supplied to the composite threads with the same treatment. Without a heat treatment executed by the pull-off organ, then a corresponding, undesired over-wetting would occur.
  • a further aim of the invention is to provide a method for the production of a multi-filament composite thread and a melt spinning device such that the wetting of the filament bundle can be used to the create a yarn effect in the composite thread.
  • This objective for the method is attained, in accordance with the invention, by passing the filament bundle through a first preparation station, either with a supplementary wetting or without a supplementary wetting.
  • the melt spinning device may include one or more preparation sites of a first preparation station that are designed such that they can be activated or deactivated for the application of a supplementary wetting of the filament bundles.
  • the invention is based on the knowledge that the preparation application to a filament bundle can be advantageously used to influence the production of composite threads. In this manner, yarn characteristics and treatment sequences can be influenced to their advantage.
  • One or all of the filament bundles can be pulled-off by the spinnerets in the dry state without supplementary wetting.
  • the method according to the invention, as well as the melt spinning device according to the invention thus establish a high degree of flexibility, in order to be able to produce composite threads of all types.
  • the filament bundles receive a main wetting in a second preparation station.
  • a preparation application is introduced to the filament bundle that is necessary for the further processing of the thread in a subsequent process following the spinning process.
  • the quantity of preparation fluid that should first be used for subsequent processes can therefore, for the most part, be left out of the melt spinning process.
  • the main wetting of the filament bundles after the drawing can be applied with identical or differing fluid applications to the filament bundles.
  • composite threads in which the yarn effect is substantially obtained by means of the polymer composition, can be obtained with filament bundles having preparation applications of equal amounts.
  • different fluid applications can be advantageously supplied to the filament bundles.
  • the method can be varied such that after the combining, the filament bundles, supplied without a supplementary wetting, are twisted during the pulling-off by means of an air treatment. In this manner, a swirl can be generated in the respective filament bundles, which ensures that the filaments within the filament bundles remain together.
  • the filament bundles can be combined in different manners to form the composite threads.
  • the filament bundles are combined by means of a swirling to form the composite threads. In this instance, a thorough mixing of the individual filament strands within the composite thread is obtained.
  • Carpet yarns also referred to as BCF yarns, can preferably be produced by means of a stuffer box texturing.
  • the filament bundles are combined by means of compression in a stuffer box and pulled-off to form the textured threads.
  • the method variation in which all filament bundles receive supplementary wetting during the process start up, preferably from a manual guidance by means of a hand-held injector, is particularly advantageous for obtaining an optimized utilization of the preparation stations in each of the operational states occurring in a melt spinning procedure.
  • the pulling-off and removal of the filament bundles to a yarn waste container is ensured without interruption if an operator threads the filament bundles successively into the processing unit of the melt spinning device with a hand-held injector.
  • a low-friction input is thus possible, such that the suction force of a hand-held injector can generate the necessary thread tension for pulling-off the filament bundles.
  • All types of multifilament composite threads can be produced with the spin melt device according to the invention.
  • the main wetting for applying the preparation fluid to the filament bundles is carried out in the preparation sites of the second preparation station, which is advantageously disposed downstream of the drawing device in the course of the thread.
  • the preparation sites of the first preparation station and/or the preparation sites of the second preparation station are designed such that they can be operated separately. In this manner, a high degree of flexibility is obtained for the selection of, and adjustment for, applying the supplementary and main wetting to the filament bundles.
  • the development of the melt spinning device according to the invention in which a swirl nozzle unit having a plurality of swirl nozzle devices is disposed downstream in the course of the thread of the preparation sites of the first preparation station, is suited, in particular, for pulling-off and drawing one or all filament bundles in the dry state.
  • the interconnection of the filaments within the filament bundles is ensured by a swirl.
  • the pull-off devices and the drawing devices are preferably designed such that the adjacent godets in the thread course can be actuated in opposing directions in order to implement an S-guidance or a Z-guidance. In this manner, compact configurations with few protruding godets and short machine frames can be obtained.
  • the compacting device for combining the filament bundles to form the respective composite threads can be designed as swirling units or texturing units.
  • a combination of the units is also possible in which the filament bundles are textured prior to combining for the production of a BCF composite thread.
