Abstract
The disclosure relates to an absorbent core capable of absorbing discharged aqueous body fluids. The core contains a swellable fluid storage material that forms, upon contact with aqueous body fluids, a fluid acquisition zone. The fluid acquisition zone is located remote from the user, to avoid flowback or rewetting of the topsheet of an article containing the core. The disclosure further relates to an absorbent article useful for absorbing discharged aqueous body fluids that comprises: A) a fluid pervious topsheet; B) a backsheet; and C) an absorbent core, as described above, positioned between the topsheet and the backsheet.
