Definitions

  • the invention relates to a method for melt-spinning, drawing and winding a multifilament yarn into an FDY yarn and to an apparatus for carrying out the method according to the preamble of claim 8.
  • a generic method for melt spinning, drawing and winding a multifilament yarn and a generic device for performing the method are, for example, from DE 31 46 054 A1 known.
  • POY yarns In the production of synthetic threads, a distinction is made between so-called POY yarns and FDY yarns depending on the degree of orientation of the molecular chains of the polymer material within the yarn.
  • POY yarns Pre Oriented Yarn (POY) yarns have a pre-oriented, unfinished structure. Such threads are preferably further processed in a draw-texturing process.
  • FDY yarns In contrast, the Full Drawn Yarn (FDY) yarns have an oriented, fully stretched structure. These threads are processed directly into a surface product without any further treatment.
  • the freshly extruded filaments are completely drawn after being brought together to form a thread and then wound up into coils.
  • a method of making a FDY thread is described. First, a plurality of filaments is extruded from a polymer melt, for example, a polyester or polyamide. The filaments are then felt to solidify or crystallize the polymeric material. For this purpose, it is customary to blow a stream of cooling air onto the filaments, so that the thread material cools to a temperature below the glass transition temperature. After cooling, the filaments of the filament bundle are brought together by means of a preparation fluid,
  • the thread already receives a Vorverstreckung, which is superimposed by a second, taking place between the godets Nachverstreckung. That from the EP 0 731 196 B1 Known method and known device is thus only suitable to produce Spezialgame by repeated heat treatments. The leadership of the thread is always carried out by godet systems, which are formed of a driven godet and an overflow roller. In that regard, a high expenditure on equipment is required to produce fully drawn threads.
  • a filament bundle is drawn directly out of the spinning zone without cooling.
  • the filament bundle is heated in several immediately adjacent to the spinneret heating zones.
  • a first heating zone is formed immediately below the spinneret.
  • the deduction of the filament bundle via heated godets, which form further heating zones.
  • the heated godets are followed by a heating tube, through which a further heating zone is formed.
  • a godet is provided to stretch the thread.
  • Another object of the invention is to provide a method and a device of the generic type, with which a plurality of parallel-spun filament bundles are possible to produce in a compact arrangement. This object is achieved by a method having the features of claim 1 and by an apparatus for performing the method with the features of claim 8.
  • the invention is based on the surprising finding that two effects characterized by reservations add positively to the stretching of the filament bundle.
  • two effects characterized by reservations add positively to the stretching of the filament bundle.
  • the invention chooses a completely new way in which the preparation of the thread takes place only after stretching, so that the filament bundle is withdrawn substantially in the dry state after cooling from the spinning zone.
  • the filaments of the filament bundle which are brought together in the dry state, thereby receive an electrostatic charge, which leads to a spreading of the filament bundle when the thread leaves the withdrawal godet.
  • this effect now has a favorable effect on the heating of the filament bundle in the hot air atmosphere of the heating tube. So can the hot air atmosphere act directly on each individual filament of the spread filament bundle and reach the desired thread temperatures even at high draw speeds.
  • Another advantage of the invention is that no additional energy is needed to evaporate the spin finish when heating the thread.
  • the filaments of the filament bundle can be treated with high efficiency in hot air atmosphere of the heating tube.
  • the filament bundle is prepared according to a preferred variant of the method immediately after heating in a stretched between two godets piece of thread. As a result, unwanted loading of the filament bundle can be avoided in the subsequent guidance and guarantee a secure thread closure until the thread is wound up.

  • a cooling air flow which acts on the filament bundle from outside to inside or from the inside to the outside.
  • the process variant is preferably used, in which the prepared yarn is heated for post-treatment at the periphery of one of the draw godets with a surface temperature in the range of 100 ° C to 180 ° C.

  • the thread has a sufficient thread closure, which are usually produced by so-called entanglement nodes, which occur during the swirling of the filament bundle.
  • the thread is swirled before winding in a stretched between two driven godets thread piece, said the swirl generates a number of at least 10 interlacing knots per meter of thread length.
  • the inventive device for carrying out the method according to the invention is characterized in that the preparation device is arranged downstream of the heating means in the yarn path and that the heating means is arranged as a heating tube with a hot air atmosphere for contactless heating of the filament bundle between the withdrawal godet and one of the draw godets.
