Abstract

Procedimiento para la fabricación de filamentos estirables con orientación molecular de modo habitual, a base de poliéster , de preferencia de poli (tereftalato de etilenglicol), por conducción de filamentos hilados a partir de un material fundido, aún no estirados, a través de un baño de agua mantenido a temperaturas entre 93 y 100ºC, siendo alargados los filamentos de modo permanentemente plástico con reducción de su orientación molecular, caracterizado porque los filamentos hilados con una velocidad de arrastre de no más de 2.500m/min, de preferencia entre 1000 y 2100 m/min, son alargados en la relación de al menos 1:3,0 de preferencia de al menos 1: 5,0 a un título individual menor de 2,5 dtex, de preferencia de 2,0 a 0,2 dtex.Process for manufacturing drawable filaments with molecular orientation in the usual way, based on polyester, preferably poly(ethylene glycol terephthalate), by conducting filaments spun from a melt, not yet stretched, through a bath of water maintained at temperatures between 93 and 100ºC, the filaments being elongated in a permanently plastic way with a reduction in their molecular orientation, characterized in that the filaments are spun with a drag speed of no more than 2,500m/min, preferably between 1000 and 2100 m/min, are elongated in the ratio of at least 1:3.0, preferably at least 1:5.0, to an individual degree of less than 2.5 dtex, preferably from 2.0 to 0.2 dtex.
