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 qui permettent de retenir des liquides corporels tels que l'urine. Ces éléments absorbants comprennent au moins un absorbant osmotique (de préférence, un polymère absorbant à formation d'hydrogel) et un matériau à surface active importante. Ils possèdent une capacité élevée d'aspiration capillaire. A des fins de la présente invention, la capacité d'aspiration capillaire est mesurée en termes de capacité de l'élément de conduire un liquide à des hauteurs capillaires importantes auxquelles on est généralement confronté lorsque l'élément est positionné dans un article absorbant. La capacité d'aspiration capillaire est notamment mesurée en termes de capacité absorbante de sorption capillaire de l'élément, mesurée selon la méthode de sorption capillaire qui est décrite dans la partie relative aux méthodes de test.
