Abstract

Procedimiento para la obtención de hilos o filamentos hidrófilos a partir de polímeros sintéticos formadores de filamentos, por hilado de una solución de polímero según el procedimiento de hilado en seco, caracterizado porque los hilos, directamente después de salir de la tobera de hilado, a más tardar sin embargo en un momento en el cual no esté aún completada la solidificación del hilo, se ponen en contacto con vapor de agua o con el vapor de otro líquido que coagule los hilos.
