ABSTRACT:
The cover sheet includes a moisture permeable top section and moisture impermeable side and bottom sections. The edges of the interior surface of the impermeable section overlap and are joined to the edges of the exterior surface of the permeable section to form an enclosure. A layer of a moisture absorbent core material is situated within the enclosure. A uni-directional barrier layer comprising a laminate of a base or carrier and an absorbent polymer which gels and expands when wetted is interposed between the permeable cover section and the absorbent core. The barrier layer includes a plurality of apertures which decreases in size as the polymer gels and expands.
