Title (EN) POLYESTER YARN AND PROCESS FOR PRODUCING
(FR) FIL DE POLYESTER ET PROCESSUS DE FABRICATION
Abstract: front page image
(EN) A multi-filament poly(trimethylene terephthalate) yarn is provided. The poly(trimethylene terephthalate) yarn has a crystal orientation function of at least 0.6 and an elongation at break of between 65% and 110%. A process for producing the yarn is also provided in which poly(triemethylene terephthalate) is melt-spun into a multi-filament yarn, the yarn is cooled to a yarn temperature of less than 50°C, and the cooled yarn is taken-up at a take-up speed of at least 3500 m/min while maintaining the temperature of the yarn at a yarn temperature of less than 50 °C.
(FR) L’invention concerne un fil poly(téréphtalate de triméthylène) multifilament. Le fil poly(téréphtalate de triméthylène) possède une fonction d’orientation cristalline d’au moins 0,6 et un allongement de rupture compris entre 65% et 110%. L’invention concerne également un processus de fabrication du fil dans lequel le poly(téréphtalate de triméthylène) est filé en fusion en fil multifilament, le fil est refroidi à une température de fil inférieure à 50°C, et le fil refroidi est pris en charge à une vitesse de prise en charge d’au moins 3500 m/minute tout en maintenant la température de fil à une température de fil inférieure à 50°C.
