摘要: The instant invention is directed to an article of manufacture for absorbing liquids. This invention comprises: a superabsorbent structure; and a permeable means for coating the superabsorbent structure. The superabsorbent structure comprises a superabsorbent polymer mixed into a matrix material, the matrix material being selected from the group consisting of cellulose ester, acrylic acid ester, polyvinyl ester, copolymers of the foregoing and combinations thereof. The permeable means is laminated onto the superabsorbent structure.
