    Abstract: Absorbent articles are provided having a bolstering waist feature. In its preferred embodiment, the bolstering waist feature expands upon exposure to aqueous body liquids effectively tightening the diaper by stretching of the waist regions of the absorbent article. There is a resulting increase in the contractive forces in the band of lateral tension in the waist regions of the absorbent article with a corresponding reduction in the risk of waist leakage. The bolstering waist feature further provides a member resisting longitudinal bending in the waist regions of the absorbent article, particularly adjacent to a wearer's belly. This member can also act as a "strut" resisting the forces, such as those due to gravity, which tend to cause an absorbent article to slide downward. The absorbent article is additionally provided with an absorbent core comprising at least a redistribution component that is preferably capable of redistributing aqueous body liquids from the crotch region to the waist regions of the absorbent article. The redistribution component is in effective fluid communication with the bolstering waist feature.

    Abstract: Described are absorbent members useful in the containment of body liquids such as urine. The storage members 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 relatively high capillary pressures, 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 of the disclosure. The absorbent members may include an osmotic absorbent (preferably a hydrogel-forming absorbent polymer) or a high surface area material, or a combination thereof.

    Abstract: Disclosed are absorbent structures comprising a first layer, a second layer juxtaposed in facing relation with said first layer, wherein at least one of the layers is fluid pervious. These structures also have a continuous region between said first and second layers comprising hydrogel-forming polymer that is substantially uniformly distributed throughout the region. The continuous region at least partially surrounds multiple, spaced apart zones between said layers, which zones are substantially devoid of hydrogel-forming absorbent polymer. The first and second layers are bonded together such that said hydrogel-forming absorbent polymer is substantially immobilized when in dry state, preferably at sites within a plurality of the zones. Preferably, the hydrogel-forming polymer has relatively high gel permeability such that it forms a gel-continuous fluid transportation layer.
