Abstract

SE DESCRIBE UNA FIBRA SINTETICA DE VOLUMEN AUMENTADO QUE COMPRENDE UN ANIMA POROSA CENTRAL Y UNA PLURALIDAD DE FILAMENTOS POROSOS LATERALES CORTOS, SOLIDARIOS DE DICHA ANIMA, DISTRIBUIDOS A TODO LO LARGO DE LA MISMA PARA CONSTITUIR UNA ESTRUCTURA RAMIFICADA VOLUMINOSA. TAMBIEN SE DESCRIBE UN PROCEDIMIENTO PARA PRODUCIR LA FIBRA QUE COMPRENDE LA MEZCLA DE UN POLIMERO SINTETICO CON UN AGENTE ESPONJANTE CAPAZ DE EXPANSIONARSE EN CALIENTE, LA HILATURA POR FUSION DE LA MEZCLA CON EL CONSIGUIENTE ESPONJAMIENTO Y DESHILACHADO DE LOS HILOS PRODUCIDOS DEBIDO AL MENCIONADO AGENTE ESPONJANTE, EL ESTIRAMIENTO Y LA FIJACION EN CALIENTE DE LOS HILOS ASI OBTENIDOS. LAS FIBRAS EN CUESTION PUEDEN EMPLEARSE, POR EJEMPLO, PARA LA FABRICACION DE FILTROS O ACOLCHADOS.
