ABSTRACT:
An absorbent article, such as a sanitary napkin, a diaper, training pants, an incontinent garment or a bedpad is disclosed for absorption of human exudate. The absorbent article includes an absorbent having a homogeneous composition with an essentially constant density in the x-y plane. The absorbent has at least two distinct portions which are integrally joined together by a junction line and each portion has a thickness different from an adjacent portion. The absorbent is folded on the junction line to obtain a variable density along the z axis. The folded absorbent also has a uniform capillary size in the x-y plane and a variable capillary size in the z direction. The absorbent article further includes a liquid-permeable cover which is positioned adjacent to at least one surface of the absorbent. A method of forming the article is also disclosed.
