Abstract

SE DESCUBREN FIBRAS INDIVIDUALIZADAS Y DEGRADADAS Y EL PROCESO DE FABRICACION DE LAS MISMAS. LAS FIBRAS INDIVIDUALIZADAS Y DEGRADADAS TIENEN UN AGENTE DE ACIDO POLICARBOXILICO EN CRUCE TRANSVERSAL CSUB2 -CSUB9 EXTENDIDO EN LA FIBRA EN FORMA DE AGLUTINANTE CRUZADO INTRA-FIBRA. PREFERENTEMENTE, EL AGENTE DE CRUCE TRANSVERSAL ES ACIDO CITRICO, Y PREFERIBLEMENTE 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. LAS FIBRAS INDIVIDUALIZADAS Y DEGRADADAS SE PUEDEN UTILIZAR EN UNA VARIEDAD DE APLICACIONES DE ESTRUCTURAS ABSORVENTES.
