Abstract
METODO PARA LA FABRICACION DE TELAS CELULOSICAS QUE TIENEN PROPIEDADES MEJORADAS DE ABSORBENCIA Y VOLUMINOSIDAD. COMPRENDE LAS SIGUIENTES OPERACIONES: PRIMERA, SE PREPARA UN MATERIAL DE POLISACARIDO MODIFICADO HACIENDO REACCIONAR UN POLISACARIDO HUMEDECIBLE POR AGUA, CON UN 25% EN PESO DE N.N-METILEN-BISACRILAMIDA, EN UN MEDIO ALCALINO ACUOSO QUE TIENE UN PH COMPRENDIDO ENTRE 8,5 Y 13,5; SEGUNDA, SE DISPERSAN LAS FIBRAS HECHAS CON EL MATERIAL DE POLISACARIDO MODIFICADO; Y POR ULTIMO, LAS FIBRAS DISPERSAS SE CONFORMAN COMO UNA TELA EN UN EQUIPO DE FABRICACION DE PAPEL.
