Abstract

LA INVENCION SE REFIERE A LA FORMACION DE FIBRAS CELULOSICAS MODIFICADAS, MEDIANTE (1) ESTERIFICACION DE FIBRAS CELULOSICAS CON UN ALQUENO SUSTITUIDO EN POSICIONES 1, 2, QUE TIENE AL MENOS UN GRUPO DE ACIDO CARBOXILICO REACTIVO FRENTE A LOS GRUPOS HIDROXILO CELULOSICOS Y (2) OXIDACION DE LAS FIBRAS ESTERIFICADAS PARA FORMAR GRUPOS ALDEHIDO. DICHAS FIBRAS MODIFICADAS SON UTILES EN PRODUCTOS DE PAPEL QUE TIENDEN A PRESENTAR UNA RESISTENCIA EN ESTADO HUMEDO TEMPORAL. SE PUEDEN AÑADIR AL PRODUCTO DE PAPEL ADITIVOS DE RESISTENCIA, PARA CONFERIR UN ELEVADO NIVEL DE RESISTENCIA EN ESTADO HUMEDO, TEMPORAL O PERMANENTE.
