An absorbent article comprising a liquid-permeable casing sheet ( ), a liquid-impermeable casing sheet ( ) and an absorbent body ( ) enclosed between the two casing sheets. The absorbent body ( ) includes a liquid acquisition space ( ) which consists of at least one cavity or one region of lower density than the density of an acquisition layer ( ) located in said absorbent body ( ) adjacent the space ( ) and essentially in the same plane thereas. The acquisition layer ( ) includes a material which when wetted increases in size in the thickness direction of the article (the z-direction). The article is mainly characterized in that the material in the acquisition layer ( ) exhibits relatively low expansion in the plane of the article (the xy-direction) when wetted, such that the volume of the liquid-acquisition space ( ) will increase by at least 100%, preferably by at least 200%, more preferably by at least 400% and most preferably by 900% when wetted.

Material having a high absorptive capacity and an absorbent structure,

The invention pertains to a foam material for absorption of aqueous liquids, a manufacturing method and an advantageous use of such a foam material, and an absorbent disposable article comprising such a foam material. The foam material is hydrophilic and primarily intended for use in absorbent disposable articles such as baby diapers, incontinence protectors and products for feminine hygiene. However, the foam material according to the invention is also suited for use in other absorbent articles, such as in different wiping materials, bandage materials and other similar products. The chemical structure of a surfactant, which is utilized as a combined emulsifying and hydrophilizing agent when manufacturing the foam material according to the invention, makes it possible to retain a sufficient proportion of the foam surfactant in the foam material even after repeated wettings, something which renders the foam material highly, permanently hydrophilic.
