Claim Text:
1. An absorbent member comprising a unitary wetlaid absorbent fibrous layer comprising at least about 90 wt. % cellulose fibers, said absorbent fibrous layer having a first surface, a second surface, a length extending in an X-direction, a width extending in a Y-direction, and a Z-direction thickness, wherein the thickness of the absorbent fibrous layer can be divided into a range of distances measured through its thickness from 0% at its first surface to 100% of the distance through its thickness at its second surface, and the length and width of the absorbent fibrous layer define an area, wherein at least a 7.2×7 2 mm square area of the absorbent fibrous layer has an average density, and a substantially continuous density profile through its thickness, and comprises a location having a maximum density, a location having a minimum density, a mean maximum density, and a mean minimum density, wherein the mean maximum density measurement through the thickness of the absorbent fibrous layer in said area is greater than 0.25 g/cc and is at least about 1.2 times its mean minimum density.
