Abstract

CARACTERIZADOS POR TENER UN TIEMPO DE ABSORCION CAPILAR INFERIOR A 50 s Y UN FLUJO ACUMULADO SUPERIOR A 0,120 g/cm�/s PARA LA DIRECCION PREFERENTE DE DISTRIBUCION DE FLUIDO QUE POSEE A 12,4 cm DE ALTURA. ADEMAS EL TIEMPO DE ABSORCION CAPILAR ES INFERIOR A 50% DEL TIEMPO DE ABSORCION CAPILAR DE LA DIRECCION PERPENDICULAR PARA LA DIRECCION PREFERENTE DE DISTRIBUCION DE FLUIDO A 8,3 cm DE ALTURA. DICHA DISTRIBUCION DE FLUIDO SE REALIZA A TRAVES DE LOS POROS DE LA ESTRUCTURA POROSA LA CUAL ES UNA MATRIZ FIBROSA QUE COMPRENDE LA MEZCLA DE POR LO MENOS UN PRIMER Y SEGUNDO TIPOS DE FIBRAS Y ADICIONALMENTE UN AGLUTINANTE, DONDE EL PRIMER TIPO DE FIBRAS, QUE ES RESILIENTE Y DE BASE CELULOSICA, ES MAS RIGIDO QUE EL SEGUNDO TIPO DE FIBRAS QUE TIENE UN AREA SUPERFICIAL ESPECIFICA MAS ELEVADA QUE EL PRIMER TIPO DE FIBRAS. DICHA ESTRUCTURA ABSORBENTE, QUE COMPRENDE UN MATERIAL DE DISTRIBUCION DE FLUIDO, SE USA EN ARTICULOS ABSORBENTES TALES COMO PANALES, PRODUCTOS DE INCONTINENCIA PARA ADULTOS Y SIMILARES
