Described are absorbent members useful in the containment of body liquids such as urine. These absorbent members comprise at least one osmotic absorbent (preferably a hydrogel-forming absorbent polymer) and a high surface area material, and have a high capillary suction capacity. For purposes of the present disclosure, capillary suction capacity is measured in terms of the member's ability to uptake liquid at high capillary heights, which are generally encountered when the member is positioned in an absorbent article. In particular, capillary suction capacity is measured in terms of a member's capillary sorption absorbent capacity, which is measured in accordance with the Capillary Sorption method described in the Test Methods section. L'invention concerne des éléments absorbants utiles dans la rétention de liquides corporels tels que l'urine. Ces éléments absorbants comprennent au moins un absorbant osmotique (un polymère absorbant formant un hydrogel) et un matériau de superficie élevée et possèdent une capacité d'absorption capillaire élevée. Selon l'invention, on mesure la capacité d'absorption capillaire en termes de capacité de l'élément à absorber un liquide à des hauteurs de capillarité élevées, que l'on trouve généralement lorsque l'élément est placé dans un article absorbant. On mesure la capacité d'absorption par capillarité selon le procédé décrit dans le chapitre Procédés de Test du descriptif.
