Abstract

Procedimiento de obtención de fibras de copolímeros, de acrilonitrilo y cloruro de vinilideno, solubles en acetona, caracterizado por comprender hilar en húmedo o en seco soluciones de acetona de los copolímeros para formar fibras que luego se estiran, y además,porque las fibras recién expulsadas se estiran de 75 a 300% a una temperatura del orden de 15º a 40 º C, después de lo cual se estiran a temperatura elevada, de modo conocida, con preferencia en vapor saturado a presión aumentada.Process for obtaining copolymer fibers, of acrylonitrile and vinylidene chloride, soluble in acetone, characterized by comprising spinning wet or dry acetone solutions of the copolymers to form fibers that are then drawn, and also, because the fibers just ejected they are drawn from 75 to 300% at a temperature of the order of 15° to 40°C, after which they are drawn at elevated temperature, in a known manner, preferably in saturated steam at increased pressure.
