ABSTRACT:
Absorbent structures having a fluid acquisition/distribution layer with an average dry density of less than about 0.30 g/cc, an average density upon wetting with 1.0% NaCl aqueous solution of less than about 0.20 g/cc, and an average dry basis weight from about 0.001 to about 0.10 g/cm.sup.2 ; and a fluid storage layer positioned beneath the acquisition/distribution layer comprising at least about 15% superabsorbent material. The fluid acquisition/distribution layer comprises from about 50% to 100% chemically stiffened cellulosic fibers and from 0% to about 50% binding means.
