Abstract

LA INVENCION SE REFIERE A UNA ESTRUCTURA ABSORBENTE QUE TIENE UNA PRIMERA CAPA QUE FORMA UNA MEZCLA DE PARTICULAS DE UN MATERIAL DE GELIFICACION ABSORBENTE Y FIBRAS Y UNA SEGUNDA CAPA QUE COMPRENDE UN SUSTRATO PERMEABLE A LOS LIQUIDOS Y PARTICULAS DE UN MATERIAL DE GELIFICACION ABSORBENTE UNIDAS A DICHO SUSTRATO FORMANDO ASI UN MATERIAL LAMINAR. EL PESO DE LAS PARTICULAS DE MATERIAL DE GELIFICACION ABSORBENTE DE LA CAPA MIXTA NO ES SUPERIOR A UN 70 POR CIENTO, PREFERENTEMENTE NO ES SUPERIOR A UN 60 POR CIENTO EL PESO DE LA CAPA MIXTA. EL PESO COMBINADO DE LAS PARTICULAS DE MATERIAL DE GELIFICACION ABSORBENTE UNIDAS AL SUSTRATO Y LAS DE LA CAPA MIXTA ES AL MENOS UN 80 POR CIENTO, PREFERENTEMENTE AL MENOS UN 140 POR CIENTO EL PESO DE LAS FIBRAS DE LA CAPA MIXTA. EL MATERIAL LAMINAR SE PUEDE COLOCAR ENCIMA DE LA CAPA MIXTA Y COMPRENDE UNA ZONA DE CAPTACION DE BAJO PESO BASE DE PARTICULAS DE MATERIAL DE GELIFICACION ABSORBENTE. EL MATERIAL LAMINAR TAMBIEN SE PUEDE COLOCAR DEBAJO DE LA CAPA MIXTA. LA INVENCION TAMBIEN SE REFIERE A UN METODO PARA LA PRODUCCION DE TAL ESTRUCTURA A BASE DE COMBINAR LA CAPA MIXTA Y EL MATERIAL LAMINAR. LA ESTRUCTURA DE LA INVENCION FIJA LA POSICION DE LAS PARTICULAS DE MATERIAL DE GELIFICACION ABSORBENTE DURANTE SU FORMACION Y USO, Y PROPORCIONA UNA CAPTACION RAPIDA DE LIQUIDOS EN LA ESTRUCTURA. LA ESTRUCTURA DE LA INVENCION ES RELATIVAMENTE DELGADA AL TIEMPO QUE MANTIENE UNA CAPACIDAD DE ABSORCION SUFICIENTE.
