Abstract

ESTRUCTURAS ABSORBENTES QUE TIENEN FIBRAS ENTRECRUZADAS INDIVIDUALIZADAS. ESTAS TIENEN PREFERIBLEMENTE ENTRE 0,5 % Y 3,5 % MOLAR DE AGENTE ENTRECRUZADO APROXIMADAMENTE, CALCULADO SOBRE UNA BASE MOLAR DE ANHIDROGLUCOSA DE CELULOSA, QUE REACCIONA CON LAS FIBRAS EN FORMA DE ENLACES ENTRECRUZADOS EN EL INTERIOR DE LA FIBRA, DONDE EL AGENTE DE ENTRECRUZAMIENTO SE ELIGE DEL GRUPO QUE CONSTA DE DIALDEHIDOS C2-C8, ANALOGOS DE ACIDO DIALDEHIDO C2-C8 QUE TIENEN POR LO MENOS UNA FUNCION ALDEHIDO, Y OLIGOMEROS DE TALES DIALDEHIDOS C2-C8 Y ANALOGOS DE ACIDO DIALDEHIDO.. MAS PREFERIBLEMENTE, EL EGENTE DE ENTRECRUZAMIENTO ES GLUTARALDEHIDO, Y ENTRE 0,75 Y 2,5 % MOLAR APROXIMADAMENTE DEL MISMO REACCIONAN PARA FORMAR LOS ENLACES ENTRECRUZADOS DENTRO DE LA FIBRA. TAMBIEN PREFERIBLEMENTE, LAS ESTRUCTURAS ABSORBENTES TIENEN MAYORES DENSIDADES EN SECO REALES QUE SUS DENSIDADES HUMEDAS DE EQUILIBRIO CORRESPONDIENTES, Y EXPANDEN POR HUMECTACION. LAS ESTRUCTURAS ABSORBENTES TAMBIEN PUEDEN CONTENER MATERIAL FORMADOR DE HIDROGEL.
