Abstract

Se describe un nucleo absorbente para usarse en un articulo absorbente, que incluye una capa fibrosa central que tiene fibras sinteticas, y dos o mas tipos de material superabsorbente (SAP). El SAP esta contenido principalmente en capas superior y/o inferior del nucleo absorbente. La capa superior y/o inferior puede ser una capa sustancialmente continua de SAP, o puede incluir una forma libre de SAP. Lascapas superior y/o inferior pueden tener una mezcla de dos o mas tipos de SAP, o pueden tener un SAP virgen no mezclado. Cada uno de los tipos de SAP tiene de preferencia una propiedad absorbente diferente (tal como alta AUL, o rapida velocidad de absorcion), por lo que el nucleo absorbente resultante se beneficia de tener varias propiedades absorbentes proporcionadas por los SAP's. Se describen tambien un articulo absorbente que incluye el nucleo absorbente, y un metodo para proporcionar un articulo absorbente que incluye el nucleo absorbente.
