Abstract

EN LA PRESENTE INVENCION SE PRESENTA UNA MALLA DE PLASTICO ELASTICA, TRIDIMENSIONAL, MACROSCOPICAMENTE EXPANDIDA, PERMEABLE A LOS FLUIDOS ADECUADA PARA UTILIZARLA COMO CAPA SUPERIOR EN ARTICULOS ABSORBENTES, ESPECIALMENTE EN ARTICULOS CATAMENIALES. LA MALLA INCLUYE UNA PRIMERA CAPA (60) DE UN MATERIAL POLIMERICO Y UNA SEGUNDA CAPA (62) DE UN MATERIAL FIBROSO ASEGURADA A LA SUPERFICIE INTERIOR DE LA PRIMERA CAPA DE MATERIAL POLIMERICO. EL MATERIAL FIBROSO DE LA CAPA INTERMEDIA SE EXTIENDE POR DEBAJO DE LA SEGUNDA SUPERFICIE (43) DE LA MALLA, ENTRANDO PREFERENTEMENTE EN EL NUCLEO ABSORBENTE (24). DURANTE SU USO, EL FLUIDO DEPOSITADO EN LA CAPA SUPERIOR SE DRENA O VACIA MAS FACILMENTE CUANDO EL MATERIAL FIBROSO DE LA SEGUNDA CAPA DISUELVE LOS MENISCOS FLUIDOS QUE SE FORMAN A LO LARGO DE LA SEGUNDA SUPERFICIE DE LA MALLA, PROPORCIONANDO ASI UNA MAYOR SEQUEDAD Y LIMPIEZA AL USUARIO.
