Definitions

  • the invention is based on the finding that, in particular in the molecular structure of a polyamide, the hydrogen bonds bring about the cohesion of the molecular chains. So it is known that in the production of the Polymer melt is used to add water to improve the stability of the polyamide melt. Thus, immediately after cooling, the filaments receive a fluid application of a wetting medium having a high water content of at least 80%. The high water content in the wetting medium allows at least some of the water on the filament to diffuse into the polyamide. Due to the absorption of water, there is the possibility that, in particular after the stretching, further hydrogen bonds are formed in order to connect the molecular chains to one another.
  • the water applied over the entire length of the filament water applications ensure a uniform water absorption, so that forms after stretching a very uniform molecular structure of the polyamide in the filaments.

Abstract

La présente invention concerne un procédé et un dispositif de production d'un fil multifilamentaire complètement étiré (FDY) à partir d'une masse fondue de polyamide. À cet effet, plusieurs filaments fraîchement extrudés sont humidifiés à l'aide d'un milieu humidifiant après un refroidissement permettant de rigidifier le polyamide et avant un étirage permettant d'orienter les chaînes moléculaires du polyamide. Afin d'obtenir en particulier une structure de chaîne moléculaire stable après l'étirage, les filaments sont, selon l'invention, humidifiés avec une proportion d'eau dans le milieu humidifiant d'au moins 80 %. Ainsi, une diffusion de l'eau dans le polyamide est possible, de telle sorte que l'eau puisse agir en tant que plastifiant et stabilisateur afin de former des structures de chaînes moléculaires stables.
