Definitions

  • the invention relates to a method for producing a highly oriented thread (HOY) from a thermoplastic material and a spinning device for melt spinning a highly oriented thread according to the preamble of claim 12
  • partially drawn threads In the production of synthetic multifilament threads from a thermoplastic melt in one process stage, a basic distinction is made between partially drawn threads and fully drawn threads.
  • the partially drawn threads have a pre-oriented molecular structure, which requires post-stretching in a second process stage. They are known as pre-oriented yarns (POY).
  • pre-oriented yarns POY
  • FDY fully drawn yarns
  • the FDY yarns are drawn up in the spinning process by means of drafting devices, so that an aligned molecular structure is established in the polymer.
  • EP 0 530 652 discloses a device and a method for producing a synthetic thread, in which the filaments are subjected to a delayed cooling before solidification. As a result, the crystallization of the filaments is further delayed, which leads to an increased elastic limit
  • the known device and the known method have the disadvantage, however, that the length of the delayed cooling can only be very limited, since the lack of stabilization of the filaments due to the blowing within this area poses an increasing risk of the filaments sticking together
  • the processes and devices known in the prior art all pursue the goal of producing a synthetic thread with the highest possible To produce winding speeds without essentially changing the physical properties. In these known processes, the reduction in elongation at higher take-off speeds is compensated for by the delayed crystallization of the polymer in the spinning line. These processes are unsuitable, however, for HOY yarns with higher elastic limits and with to produce higher strengths
  • FIG. 3 shows a top view of an exemplary embodiment of a spinneret 2, as would be used, for example, in the spinning device according to FIG. 1 or FIG. 2.
  • the nozzle bores 33 are arranged in a ring in a row 34 of bores.
  • the nozzle bores 33 are in the row of bores 34 each with the same distance from each other in the spinneret 2, concentric with the row of bores 34, further nozzle bores are made in a second row of bores 36.

Abstract

L'invention concerne un procédé et un dispositif de filage pour la production d'un fil hautement orienté (HOY = high oriented yarn) à partir d'un matériau thermoplastique. Selon ledit procédé, le fil est retiré d'une filière à une vitesse de retrait d'au moins 6 500 m/min, les filaments formant le film étant étirés lors de la solidification, de telle sorte qu'une structure moléculaire hautement orientée se forme dans le polymère. Pour que la tension de retrait produite par la vitesse de retrait élevée n'entraîne aucune surcharge des filaments lors de l'étirage, les filaments sont, avant la solidification, assistés dans leur progression, de telle sorte qu'avant la solidification, une diminution de tension de traction se produise sur les filaments et que, pendant la solidification, une tension de retrait réduite s'exerce sur les filaments, lors de l'étirage.
