ABSTRACT:
The present invention relates to water swellable, water insoluble superabsorbent materials having controlled variable gel-bed friction angles. Controlling the gel-bed friction angle of the superabsorbent materials may allow control of the swelling of the material, the absorbency of the material, and/or the absorbency, resiliency, and porosity of the absorbent composite containing the superabsorbent material. The present invention relates to treatments for superabsorbent materials to manipulate friction angle and new superabsorbent materials having the desired friction angle characteristics. The present invention also relates to absorbent composites employing superabsorbent materials having the desired friction angle characteristics.
