Abstract

SE PRESENTA UN METODO PARA LA MODIFICACION SUPERFICIAL DE UNA FIBRA DE CELULOSA Y EL PRODUCTO RESULTANTE, CELULOSA SULFONADA. PRIMERO SE OXIDA LA CELULOSA, PREFERENTEMENTE CON METAPERIODATO SODICO (NAIO{SUB,4}) PARA OBTENER OXICELULOSA DE DIALDEHIDO, QUE A CONTINUACION SE LE HACE REACCIONAR CON BISULFITO SODICO (NAHSO{SUB,3}) PARA OBTENER CELULOSA SULFONADA. LA SULFONACION DE LA FIBRA DE CELULOSA AUMENTA SIGNIFICATIVAMENTE LA RESISTENCIA A LA TRACCION EN ESTADO SECO Y EN ESTADO HUMEDO ASI COMO LA RELACION DE RESISTENCIA EN ESTADO HUMEDO:RESISTENCIA EN ESTADO SECO, LO QUE HACE QUE ESTA FIBRA DE CELULOSA MODIFICADA SEA EXTREMADAMENTE UTIL PARA UNA AMPLIA VARIEDAD DE PRODUCTOS DE PAPEL EN LOS QUE SE REQUIERE UNA COMBINACION DE BUENA RESISTENCIA TANTO EN APLICACIONES EN ESTADO HUMEDO COMO EN ESTADO SECO.
