Abstract

La presente invención se refiere a procedimiento para fabricar un artículo poroso de un material de éster de celulosa, que se caracteriza porque consiste de las etapas de: a) proporcionar un baño de coagulación que contiene un líquido acuoso que tiene inmerso en el mismo un surtidor del tipo de tubo dentro de un anillo; b) establecer una comunicación fluida entre el líquido acuoso contenido en el baño de coagulación y el tubo del surtidor previendo una abertura en dicho tubo por debajo de la superficie del líquido acuoso; c) extruir una solución de hilatura que consiste de por lo menos un material de éster de celulosa y un solvente directamente en el líquido acuoso contenido en el baño de coagulación a través de un anillo que rodea al tubo del surtidor para formar una fibra extruída que consiste esencialmente de dicho material de éster de celulosa, permitiendo al mismo tiempo, mientras tanto, que una porción del líquido acuoso contenido en dicho baño de coagulación sea aspirada autógenamente a través de la abertura y hacia el interior del tubo para formar de esta manera un canal central en la fibra extruída; y en seguida d) secar la fibra extruída para producir una fibra hueca formada de dicho material de éster de celulosa.
