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.
