Abstract
The present invention relates in one aspect to absorbent articles that maintain or increase fluid acquisition rates when subjected to successive fluid loads. In another aspect, the invention relates to an absorbent article useful for absorbing discharges of aqueous body fluids which has a fluid pervious topsheet, a backsheet and an absorbent core, the absorbent core including at least one upper storage component in direct fluid communication with the topsheet capable of expanding in the z-direction to form a fluid acquisition zone when contacted with aqueous body fluids, the acquisition zone being at least partially surrounded by the upper fluid storage component and beneath the fluid discharge region of the core, and a fluid acquisition/distribution component having at least a portion positioned underneath and in fluid communication with the storage component and acquisition zone.
