Definitions

  • the invention relates to a method for producing a multifilament composite thread in a melt spinning process according to the preamble of claim 1 and to a melt spinning device according to the preamble of claim 10.
  • the composite yarn thus consists of at least two filament bundles, each having a plurality of filament strands which are combined after stripping and stretching to the composite thread.
  • the filaments of the filament bundles can be made of a same polymer material with the same additives, the yarn effects are based essentially on the different treatments of the filament bundles.
  • composite threads can be produced in which the filaments have different shrinkage behavior in order to obtain a type of crimping, for example, in further processing by forming bends and loops.
  • the filament bundles of a composite thread made of a polymer material with different additives for example produce different color pigments.
  • the yarn effects in the composite thread are essentially shaped by the visual appearance.
  • the treatment of the filament bundles to form the composite thread is the same for both filament bundles.
  • carpet yarns are produced in a mixed color, which results from the merging of differently colored filament bundles.
  • the preparation quantity which is missing for optimal further processing is applied in a second wetting.
  • the filament bundles are wetted with a predetermined subset of a preparation fluid.
  • the known method and the known melt spinning apparatus are based on feeding each of the filament bundles to the composite yarn with equal treatment. Without a heat treatment carried out before the take-off device, unwanted over-moistening would accordingly set in.
  • a further object of the invention is to develop a method for producing a multifilament composite thread and a melt spinning apparatus such that the wetting of the filament bundles can be used specifically for setting yarn effects in the composite thread.
  • melt spinning apparatus of claim 10 wherein the preparation sites of a first preparation station for selectively applying an auxiliary wetting to the filament bundles are designed to be activatable or deactivatable.
  • the invention is based on the finding that the preparation application of a filament bundle can be advantageously used to influence the production of composite filaments.

  • the inventive method as well as the melt spinning device according to the invention thus form a high flexibility to be able to produce composite threads of all kinds.
  • the filament bundles are given a main wetting after being drawn in a second preparation station.
  • the main wetting essentially the spin finish preparation process required for the further processing of the thread in a subsequent process is introduced into the filament bundle.
  • the amounts of the preparation fluid which should only be usable for subsequent processes, can therefore be kept to a large extent out of the melt spinning process.
  • the main wetting on the filament bundles can be applied to the filament bundles after stretching with equal or unequal fluid applications.
  • composite yarns in which yarn effects are produced essentially by the polymer composition can be formed by filament bundles with uniformly sized preparation jobs.
  • unequal fluid orders can advantageously also be supplied to the filament bundles.
  • the method variant is preferably carried out in which, after the merging, the filament bundles guided without auxiliary wetting are twisted during removal by an air treatment. This allows a swirl generated at the respective filament bundles, which ensures the cohesion of the filaments within the filament bundle.
  • the stripping and stretching of the filament bundles is preferably carried out by a plurality of godets, on which the filament bundles are held individually or together side by side with an S-guide or Z-guide.
  • the preparation application in the auxiliary wetting and in the main wetting is adjusted to whether a simultaneous heat treatment has to take place via the godets.
  • a so-called boil-out of the water from the filament bundle can advantageously be dispensed with by a very small proportion of water in the preparation application in the auxiliary wetting.

  • the withdrawal as well as the removal of the filament bundles for a Garnabfall constituer must be ensured without interruption when an operator with a hand injector threading the filament bundles sequentially in the process units of the melt spinning device.
  • a low-friction inlet is thus possible, so that the suction force of a hand injector can produce the required thread tension for the withdrawal of the filament bundles.
  • the melt spinning device With the melt spinning device according to the invention, all types of multifilament composite yarns can be produced.
  • the main wetting for application of the preparation fluid to the filament bundles is carried out in the preparation stations in the second preparation station, which is advantageously arranged downstream of the drawing device in the yarn path.
  • the amounts of preparation fluid can be applied to the filament bundles, which is required for the respective process and for the further treatment of the respective filament bundle.

  • so-called BSY yarns can advantageously be produced in which the filament strands of the composite thread have different shrinkage inclinations which can be triggered during a heat treatment and lead to loops and bends in the composite thread.
  • the cooling device 4 can be further developed in such a way that the filament bundles 3.1 and 3.2 are cooled by different generated cooling air streams.
  • the process according to the invention and also the melt spinning device according to the invention thus offers a high degree of flexibility in the production of composite yarns of different types. It is essential here that the thread wetting applied to the respective filament bundles in the preparation stations is controllable or switchable. On the one hand, this makes it possible to perform a wetting adapted to the respective treatment and, on the other hand, to produce additional effects in the formation of the composite thread.
