Abstract
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.
