Patent

CA 2152753

A multilayered absorbent structure is disclosed. The absorbent structure has a plurality of absorbent planar regions defined by decreasing pore size with increasing depth into the region. Generally, each planar region has an absorbent layer having relatively large average pore sizes at the top, body facing surface, and relatively small average pore sizes at the bottom, garment facing surface. A subsequent absorbent region has a top body facing surface with an average pore size which is larger than the bottom, garment facing surface of the previous absorbent region. The top surface of each subsequent planar region is in fluid communication with the lower surface of the planar region above.
