Definitions

  • the present invention relates to an apparatus for producing an HMLS yarn from polyester.
  • HMLS High Modulus Low Shrinkage yarns are mainly used in tire reinforcement, the so-called tire cord.
  • a large number of filament strands are extruded through spinnerets in a spinning device and then cooled. Cooling is mostly done with air in a so-called blow chute.
  • the filament strands are combined into a yarn and stretched in a stretching zone.
  • the yarn is then wound onto a bobbin.
  • the starting product used to manufacture the game and the way the filament strands are stretched influence the properties to be achieved in the end product. It should be emphasized here that a large proportion of the total stretching takes place between the spinneret and the merging of the filament strands into a yarn.
  • the filament strands leave the spinneret at a speed of around 10 m/min and are drawn off by an infeed roller at the start of the drawing zone at around 2,000 m/min. Between the spinneret and the infeed roller, the filament strands are stretched by about 200 times their length. This results in very high speeds of the rolls and spools in the drawing zone as well as on the winder. Due to the high speed, the thread guide elements are also heavily stressed. This leads to high wear and a correspondingly short service life for the elements used.
  • the device for producing an HMLS yarn from a PET-polyester melt comprises a spinning device with a spinneret for extrusion and a blowing shaft for cooling a large number of filament strands, a device for applying a spin finish and for combining the filament strands into a thread, with a winding device and with a stretching zone provided between the spinning device and the winding device for stretching the thread.
  • the draw zone is formed by a pair of inlet rollers arranged after the spinning device and subsequent five pairs of draw rollers.
  • the first pair of stretching rolls are provided with a heating device and the last pair of stretching rolls are provided with a cooling device. At least one of the two rolls of a respective pair of stretching rolls is provided with a heating or cooling device.
  • the speed at which the thread is drawn off the spinning device by the pair of infeed rollers is 400 m/min to 700 m/min.
  • the active cooling of the thread via the last pair of stretching rollers influences the molecular chains in the polyester, which leads to an increase in strength.
  • the crystallinity and the orientation of the molecules are influenced and the molecular structure is fixed by cooling.
  • the active cooling of the thread at the end of the drawing zone reduces the distortion of the filament strands in the spinning process compared to conventional Process can be greatly reduced and still a thread with a high modulus with low shrinkage (shrinkage) can be produced.
  • the stretching amounts in detail between the pair of infeed rollers and the first pair of stretching rollers 1.02 to 1.1, between the first pair of stretching rollers and the second pair of stretching rollers 4 to 6, between the second pair of stretching rollers and the third pair of stretching rollers 1.2 to 2.0, between the third pair of stretching rollers and the fourth pair of stretching rollers 0.7 to 1.2 and between the fourth pair of stretching rollers and the fifth pair of stretching rollers 0.7 to 1.2.
  • a surface temperature of less than 100° C. of the roller of the last pair of stretching rollers provided with the cooling device is provided.
  • the surface temperature is preferably less than 80°C.
  • the cooling effect on the thread repeatedly wrapped around the pair of stretching rollers can be additionally increased in that both rollers of the last pair of stretching rollers are provided with a cooling device.
  • Liquid cooling is best suited as a cooling device. Heat is extracted from the thread via the surface of the roll. The heat is dissipated via a cooling liquid circulating in the roller and is in turn extracted from the cooling liquid in a heat exchanger. The temperature of the coolant is controlled in such a way that the surface temperature of the roller does not exceed the specified temperature of 100°C, preferably 80°C.
  • Such cooling systems are known from the prior art.
  • the pair of infeed rollers as well as the pairs of stretching rollers can be designed as so-called duos with two driven rollers or as so-called monos with one driven roller and an associated auxiliary roller.
  • one infeed roller and five pairs of stretching rollers are used, with the infeed roller being designed as a mono and the pairs of stretching rollers as a duo.
  • the respective pairs of rollers are looped around several times by the thread.
  • the stretching zone is formed by the pair of entry rollers and the subsequent pairs of stretching rollers.
  • Five pairs of stretching rollers are preferably arranged downstream of the pair of infeed rollers.
  • a total stretching of the thread entering from the spinning device to three to eight times its original length is provided over the entire stretching zone.
  • the total drawing is preferably five to seven times.
  • the stretching between the pair of infeed rollers and the first pair of stretching rollers is 1.04, between the first pair of stretching rollers and the second pair of stretching rollers 4.6, between the second pair of stretching rollers and the third pair of stretching rollers 1.3, between the third pair of stretching rollers and the fourth pair of stretching rollers 0.96 , and between the fourth pair of draw rolls and the fifth pair of draw rolls, 0.97.
  • the actual stretching takes place between the pairs of stretching rollers.
  • the two rolls of a pair of stretching rolls are operated at essentially the same speed.
  • the temperatures of the heated stretching rolls are to be provided according to the polyester melt used. At least one of the two rollers in a pair of stretching rollers is heated. Both rolls of a pair of stretching rolls are preferably heated to the same temperature.
  • the surface temperatures are in the range of 40°C to 90°C for the first pair of stretching rolls, 80°C to 170°C for the second pair of stretching rolls, 120°C to 280°C for the third pair of stretching rolls and 120°C to 250°C for the fourth pair of stretching rollers. In a preferred embodiment, the surface temperatures are 85°C for the first pair of stretching rollers, 110°C for the second pair of stretching rollers, 250°C for the third pair of stretching rollers and 250°C for the fourth pair of stretching rollers.
  • the fifth pair of stretching rollers Due to the cooled surface, the fifth pair of stretching rollers has the effect that the molecular orientation within the individual filaments of the thread is influenced and fixed, resulting in greater strength.
  • threads can be produced which have a strength of more than 70 cN/tex with an elongation of less than 13%.
  • the threads produced in this way also have a shrinkage of less than 4%, preferably less than 3.2%.
  • the thread is exposed to a temperature of 180° C. for a period of 15 minutes. During this measurement, the thread is kept under a constant tension of 0.1 cN/tex (BISFA standard).
  • the method for producing an HMLS yarn from a PET-polyester melt using the device according to any one of claims 1 to 7 comprises the method steps according to claim 8.
  • the filament strands are stretched between the spinneret and the pair of inlet rollers by a factor of 50 to 80, preferably by a factor of 60, and wound up at a speed of 1500 to 3500 m/min.
  • the synthetic polyester melt preferably used in the process according to the invention has an intrinsic viscosity of less than 0.9 dl/g.
  • the invention is based on an exemplary embodiment based on the figure 1 explained in more detail.
  • FIG 1 shows a schematic representation of an embodiment of a device for producing a continuous thread from a synthetic polymer melt.
  • a large number of filament strands 4 are extruded with a spinning device 1 at a temperature of 40° to 50° above the melting temperature of the polyester used.
  • the spinning device 1 comprises a spinneret 2 through which the individual filaments of the filament strand are formed.

  • the cooling usually takes place by blowing cooled blown air onto the filament strands 4 .
  • the filament strands 4 are then combined into a thread 6 and provided with a spin finish 5 .
  • the thread 6 arrives at a pair of inlet rollers 7.
  • the pair of inlet rollers 7 consists of a driven roller and a non-driven auxiliary roller.
  • the take-off speed V2 of the thread from the blowing chute 3 is determined by the pair of infeed rollers 7 .
