Abstract

La presente invención se refiere a estructuras no tejidas de múltiples capas que son útiles como componentes de prendas y artículos absorbentes desechables que comprenden partículas superabsorbentes y, de esta manera, actúan como un núcleo. La invención asegura de esta manera que los fluidos corporales pueden penetrar desde una primera capa, que actúa como una capa de adquisición, hasta una tercera capa que comprende las partículas SAP, la segunda capa no tejida sirve para disminuir el volumen de fluido por unidad de superficie, como una capa de dispersión convencional. Sin embargo, la segunda capa de la invención actúa adicionalmente como una válvula de retención, que evita, o al menos limita fuertemente, cualquier transferencia de fluido desde la tercera capa hasta la primera capa. Adicionalmente, pueden diseñarse canales libres de SAP para mejorar las propiedades de entrada y rehumectación del material no tejido de láminas de adquisición y distribución de múltiples capas.
