Abstract

La presente invención se refiere a un hilo de alimentación con estirados y textura mejorados, hecho de copoliéster catiónico teñible, en el que el copoliester catiónico teñible cosnta esencialmente de poli(tereftalato de etileno/isoftalato de 5 (sodio-sulfo), que contiene alrededor del 2 por ciento molar de los grupos de isoftalato de 5-(sodio-sulfo) en la cadena de polímero, y este hilo de alimentación es un hilo de múltiples filamentos, con hilado orientado, substancialmente amorfo, preparado hilando a una velocidad de retirada del orden de unos 3000 hilos por minuto o más, la mejora consiste en que los filamentos son de dos componentes, de envoltura concentrica/núcleo, en que la envoltura consta esencialmente del copoliéster catiónico teñible y el núcleo consta esencialmente de poli(tereftalato de etileno), con una viscosidad intrínseca de aproximadamente 0.6.The present invention relates to a feed yarn with improved stretches and texture, made of dyeable cationic copolyester, in which the dyeable cationic copolyester is essentially poly (ethylene terephthalate / 5 (sodium-sulfo) isophthalate) containing about 2 mole percent of the 5- (sodium-sulfo) isophthalate groups in the polymer chain, and this feed yarn is a oriented, substantially amorphous, multi-filament yarn oriented spinning prepared at a withdrawal rate on the order of about 3000 yarns per minute or more, the improvement is that the filaments are two-component, concentric / core wrap, where the wrap consists essentially of the dyeable cationic copolyester and the core consists essentially of poly (ethylene terephthalate) ), with an intrinsic viscosity of about 0.6.
