Abstract

UN PROCESO MEJORADO PARA LA PRODUCCIÓN DE CELULOSA MICROFIBRILADA (MFC), QUE COMPRENDE LAS ETAPAS DE: - PRE-TRATAR LAS FIBRAS CON UNA ENZIMA EN UN PRIMER TRATAMIENTO ENZIMÁTICO, DONDE LA ENZIMA DURANTE EL PRIMER TRATAMIENTO ENZIMÁTICO TIENE UNA ACTIVIDAD QUE FLUCTÚA ENTRE 0,01 Y 250 NKAT/G - PRE-TRATAR MECÁNICAMENTE LAS FIBRAS EN UN PRIMER TRATAMIENTO MECÁNICO, TRATAR LAS FIBRAS CON UNA ENZIMA EN UN SEGUNDO TRATAMIENTO ENZIMÁTICO, DONDE LA ENZIMA DURANTE EL SEGUNDO TRATAMIENTO ENZIMÁTICO TIENE UNA ACTIVIDAD QUE FLUCTÚA ENTRE 50 Y 300 NKAT/G Y LA ACTIVIDAD DE LA ENZIMA EN EL SEGUNDO TRATAMIENTO ENZIMÁTICO ES MAYOR QUE EN EL PRIMER TRATAMIENTO ENZIMÁTICO Y POSTERIORMENTE, TRATAR MECÁNICAMENTE LAS FIBRAS EN UN SEGUNDO TRATAMIENTO MECÁNICO PARA FORMAR CELULOSA MICROFIBRILADA.
