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.
