ABSTRACT:
An absorbent composite of the type comprising a porous matrix of fibers and a superabsorbent material dispersed among the interfiber spaces (pores) wherein the superabsorbent material exhibits the ability to absorb greater than about 24 milliliters of a saline solution per gram of superabsorbent material under an applied restraining force of at least about 21,000 dynes/square centimeter provided that, when in the form of discrete particles, at least about 50% of said superabsorbent material has a size greater than the median pore size of the matrix when wet.
