Abstract:
An absorbent structure consisting essentially of:a. from about 25 to about 99 weight percent superabsorbent material wherein the superabsorbent material is capable of absorbing an amount of water at least about 10 times the weight of the superabsorbent material;b. from greater than 0 to about 35 weight percent wettable staple fiber, wherein the wettable staple fiber exhibits a length that is from about 0.2 centimeter to about 15 centimeters; andc. from greater than 0 to about 40 weight percent wettable binder fiber;wherein all weight percents are based on the total weight of the superabsorbent material, wettable staple fiber, and wettable binder fiber in the absorbent structure, and wherein the absorbent structure exhibits a liquid uptake rate at least about 2 times greater than the liquid uptake rate exhibited by an otherwise substantially identical absorbent structure without any wettable staple fiber for any of three 60 milliliter insults of synthetic urine at about 23.degree. C. applied at a rate of about 15 milliliters/second with about 5 minutes between each insult wherein the insults are applied to the absorbent structure with an absolute liquid saturated retention capacity of at least about 240 milliliters.
