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.

Abstract: The napkin has flaps 20 extending from opposite sides of a central absorbent portion which comprises a liquid impermeable backsheet 2, an absorber 3 and a liquid permeable topsheet 1. The flaps are composed of film having a base weight of 30 to 90 g/m2 and comprising material having a resin density of 0.910 to 0.940 g/cm3, particularly a polyolefin or olefin copolymer. The flaps carry adhesive layers 5 and may be embossed to provide protuberances 6.

Abstract: A bulky sheet material having three-dimensional protrusions (10) is disclosed. The sheet material comprises a first layer(1)and a second layer(2)adjacent to the first layer (1). The first layer(1)and the second layer(2)is partly joined together at joints(3)in a prescribed pattern. The first layer(1) has a number of raised portions which are located among the joints (3). The second layer (2) comprises a material which exhibits elastomeric behavior. The bulky sheet material (10) exhibits elastomeric behavior as a whole and breathability.
