An absorbent composite suitable for use in a disposable absorbent garment includes material for containing a superabsorbent material and a supersbsorbent material contained by said containment material. The superabsorbent material has a Pressure Absorbency Index of at least 100 and a 16-hour extractable level of less than about 13 weight percent; a Pressure Absorbency Index of at least 100 and a Vortex Time of less than about 45 seconds; or a Pressure Absorbency Index of at least about 110. The superabsorbent material is present in the containment means in an amount of from about 30 to about 100 weight percent based on total weight of the containment material and the superabsorbent material. A disposable absorbent garment includes an outer cover, a body-side liner, and an absorbent composite such as that described above.

1. A method of testing superabsorbent materials for their suitability for use in absorbent composites to be included in disposable absorbent garments, said absorbent composites comprising from about 30 to about 100 weight percent of superabsorbent material, said method comprising the steps of (a) determining the absorbency under load characteristics of the superabsorbent materials at restraining forces of 0.01, 0.29, 0.57, and 0.90 pounds per square inch, (b) determining the total of the absorbency under load characteristics at each said restraining force for each superabsorbent material, and (c) choosing as suitable a superabsorbent material for which the total of said absorbency under load characteristics is at least about 110. (c) choosing as suitable a superabsorbent material for which the total of said absorbency under load characteristics is at least about 110. 2. The method according to claim 1 wherein the superabsorbent material chosen has a total of said absorbency under load characteristics of at least about 120. 3. The method according to claim 1 wherein the superabsorbent material chosen has a total of said absorbency under load characteristics of at least about 140. 4. The method according to claim 1 wherein the superabsorbent material chosen also has a 16-hour extractables level of less than about 10 weight percent. 5. The method according to claim 1 wherein a superabsorbent material chosen also has a 16-hour extractables level of less than about 7 weight percent. 6.
