Abstract: An absorbent article using, as a surface material (or a liquid-permeable top sheet), a nonwoven fabric is disclosed, the nonwoven fabric containing at least 10% by weight of a conjugate fiber comprising first and second parts differing from each other, wherein the second part covers at least a part of the first part, at least the first part contains an inorganic component in a proportion higher than that contained in the second part, and the content of the inorganic component in the first part is at least 1.5% by weight based on the weight of the first part. The nonwoven fabric has excellent cutting properties while retaining satisfactory strength, absorbency and touch.

Abstract: An absorbent article comprises a liquid-permeable surface sheet, a liquid-impermeable leak-proof sheet and an absorbent layer disposed between the two sheets, said leak-proof sheet having on the outside surface a composite comprising a hydrophobic polymer having a glass transition temperature of zero degree centigrade or lower and foamed beads of a polymer. It is improved in the anti-slipping property, the leak-proof property and the permeability to moisture.

Abstract: An absorbent article, such as a sanitary napkin or disposable diaper, comprises a liquid permeable top sheet (6), a liquid impermeable bottom sheet (5) and an absorbent element 1 interposed between them. The absorbent element comprises two layers of fibrous material, the first absorbent layer (2) close to the bottom sheet having a higher density than the second absorbent layer (3) close to the top sheet. The first absorbent layer (2) has a plurality of layers of cavities (4) distributed over its entire thickness, the area occupied by the cavities amounting to 45 to 80% of the cross-sectional area.
