Abstract

PROCESO PARA LA PREPARACION DE FIBRAS INDIVIDUALIZADAS Y DEGRADADAS QUE INCLUYE LOS PASOS PARA SUMINISTRAR FIBRAS DE CELULOSA, PONIENDO EN CONTACTO LAS FIBRAS CON UNA SOLUCION QUE CONTIENE UN AGENTE ACIDO POLICARBOXILICO DE CRUCE TRANSVERSAL C SUB 2 AGENTE Y SEPARA MECANICAMENTE LAS FIBRAS EN FORMA SUSTANCIALMENTE INDIVIDUAL, Y SECA LAS FIBRAS Y REACTIVA EL AGENTE DE CRUCE TRANSVERSAL CON LAS FIBRAS INDIVIDUALIZADAS ASI COMO LOS AGLUTINANTES DE CRUCE TRANSVERSAL. PREFERENTEMENTE, EL AGENTE DE CRUCE TRANSVERSAL ES ACIDO CITRICO, Y PREFERENTEMENTE, ENTRE ALREDEDOR DE UN 0.5 % DE MOL Y ALREDEDOR DE UN 10.0 % DE MOL DEL AGENTE DE CRUCE TRANSVERSAL REACCIONA PARA FORMAR LOS AGLUTINANTES DE CRUCE TRANSVERSAL INTRA-FIBRA. ESTAS FIBRAS INDIVIDUALIZADAS Y DEGRADADAS SE USAN EN UNA VARIEDAD DE APLICACIONES DE ESTRUCTURA ABSORBENTE.
