Abstract

LA INVENCION CORRESPONDE A UN PROCESO PARA PREPARAR UNA SOLUCION ISOTROPA HILABLE QUE CONTIENE 94-100 % EN PESO DE LOS CONSTITUYENTES CELULOSA, ACIDO FOSFORICO Y/O SUS ANHIDRIDOS, Y AGUA, CUYA SOLUCION SE OBTIENE DISOLVIENDO CELULOSA EN UN SOLVENTE QUE CONTIENE ACIDO FOSFORICO, CONTENIENDO EL SOLVENTE 68-85 % EN PESO DE PENTOXIDO DE FOSFORO, CALCULADO SOBRE LA CANTIDAD GLOBAL DE AGUA Y ACIDO FOSFORICO EN EL SOLVENTE. LA SOLUCION PUEDE SER UTILIZADA PARA FABRICAR FIBRAS (HUECAS), MEMBRANAS, NO TEJIDOS, PELICULAS, Y EN OTRAS APLICACIONES CONOCIDAS DE LAS SOLUCIONES DE CELULOSA.
