发明名称 ABSORPTIVE BODIES HAVING IMPROVED LIQUID COLLECTION PROPERTIES FOR USE IN ABSORPTIVE ARTICLES
摘要 An absorbent article comprising a liquid-permeable casing sheet (1), a liquid-impermeable casing sheet (2) and an absorbent body (3) enclosed between the two casing sheets. The absorbent body (3) includes a liquid acquisition space (24) which consists of at least one cavity or one region of lower density than the density of an acquisition layer (19) located in said absorbent body (3) adjacent the space (24) and essentially in the same plane thereas. The acquisition layer (19) 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 (19) exhibits relatively low expansion in the plane of the article (the xy-direction) when wetted, such that the volume of the liquid-acquisition space (24) will increase by at least 100%, preferably by at least 200%, more preferably by at least 400% and most preferably by 900% when wetted.
