Abstract

Metodo para modificar fibras de celulosa, caracterizado porque las fibras de celulosa se tratan durante al menos 5 minutos con una disolucion acuosa que contiene electrolito de un derivado de celulosa anfotera, mediante lo cual la temperatura durante el tratamiento es de al menos 50°C, y se aplica al menos una de las siguientes condiciones: A) el pH de la disolucion acuosa durante el tratamiento se encuentra en el intervalo de aproximadamente 1,5-4,5, preferiblemente en la regi6n de 2-4; o C) la concentracion del electrolito en la disolucion acuosa se encuentra en el intervalo de aproximadamente 0,0001-0,05 M, preferiblemente de aproximadamente 0,001-0,04 M, si el electrolito tiene cationes monovalentes, o en el intervalo de aproximadamente 0,0002-0,1 M, preferiblemente de aproximadamente 0,0005-0,02 M, si el electrolito tiene cationes divalentes, en el que el derivado de celulosa anfotera es un derivado de CMC y se ha cationizado hasta un grado de sustitucion de hasta 1,0.
