Abstract

EL PRESENTE INVENTO SE REFIERE A UN METODO PARA LA MODIFICACION DE SUPERFICIES DE LA FIBRA DE CELULOSA Y EL PRODUCTO RESULTANTE, CELULOSA SULFONATADA, LA CELULOSA ES PRIMERO OXIDIZADA, PREFERIBLEMENTE CON ETA PERIODATO SODICO (NaIO4), PARA FORMAR DIALDEHIDO OXICELULOSA, LA CUAL ES ENTONCES REACCIONADA CON BISULFITO SODICO (NaHSO3), PARA PRODUCIR CELULOSA SULFONATADA, LA SULFONACION DE LA FIBRA DE CELULOSA AUMENTA SIGNIFICATIVAMENTE LA RESISTENCIA A LA TENSION EN HUMEDO Y EN SECO ASI COMO LA PROPORCIONAR DE RESISTENCIA EN HUMEDO; RESISTENCIA EN SECO, HACIENDO A ESTA FIBRA DE CELULOSA MODIFICADA EXTREMADAMENTE UTIL EN UNA AMPLIA VARIEDAD DE PRODUCTOS DE PAPEL QUE REQUIEREN UNA COMBINACION DE BUENA RESISTENCIA EN AMBAS APLICACIONES EN HUMEDO Y EN SECO.
