ABSTRACT:
One aspect of the present invention relates to an absorbent structure and garment comprising a superabsorbent material having a free-swell rate of less than about 60 seconds and a five-minute AUL of at least 15 g/g. The superabsorbent material is contained by containment means, such as a fibrous matrix, such that the superabsorbent material is present in said absorbent structure in an amount of from about 60 to about 100 weight percent based on the total weight of the containment means and superabsorbent material.
A second aspect relates to an absorbent garment including containment means containing a high concentration of a superabsorbent material and defining a dry volume less than about 180 cubic centimeters. The absorbent garment has a saturated retention capacity of at least about two times the dry volume, and wherein the containment means and superabsorbent material account for at least about 60 volume percent of said saturated retention capacity.
