Abstract

La présente invention concerne, d'une part un procédé de production de fil FDY (entièrement orienté au filage) par filage à l'état fondu, d'étirage, et de déroulement d'un filé multifibre, et d'autre part un procédé d'exécution du procédé. En l'occurrence, on commence par extruder à partir d'une matière thermoplastique en fusion une pluralité de filaments, on refroidit ensuite cette pluralité de filaments à une température inférieure à la température de transition vitreuse de la matière thermoplastique, et enfin, on utilise un sol de finition d'une teneur maximale en eau de 8% pour réunir les filaments un faisceau de filaments. Ensuite, pour tirer sur le faisceau de filaments, on lui fait subir un enroulement partiel à une vitesse supérieure à 1.200 m/mn sur une chape de guidage éventuellement chauffée comportant des galettes subissant un mouvement d'entraînement. Pour l'étirage et le relâchement consécutif, on fait passer le faisceau de filaments à une vitesse d'étirement supérieure à 3.500 m/mn en enroulement partiel simple autour de galettes subissant un mouvement d'entraînement équipant d'autres chapes chauffées. À cet effet, le dispositif de l'invention comprend deux groupes de galettes comprenant plusieurs galettes subissant un mouvement d'entraînement, le premier groupe de galettes provoquant le tirage et/ou le réchauffage du filament au cours d'un enroulement partiel simple, le second groupe de galettes provoquant par enroulement partiel simple l'étirement du faisceau de filaments.
