Abstract

An absorbent article wherein the deposition region of its absorbent member comprises a storage zone and an acquistion zone having a lower average density and a lower average basis weight per unit area than the storage zone. The acquisition zone is positioned toward the front of either the absorbent member or the absorbent article so that the acquistion zone may most effectively and efficiently rapidly acquire discharged liquids. The absorbent member also comprises a mixture of hydrophilic fibrous material and discrete particles of absorbent gelling material to enhance the absorbent capacity of the absorbent member.
