Abstract: Hydrogel composites are provided having improved fluid absorption efficiencies which render them especially useful in disposable absorbent articles, such as diapers, catamenial devices and the like. The hydrogels are in particulate form, each particle or agglomerate of particles being substantially coated with fibers, a portion of which fibers extend from the particle. The fibers enhance the rate at which the hydrogel absorbs aqueous fluids and also serve to maintain the fluid in close proximity to the hydrogel. The extended fibers serve to anchor the hydrogel particle when it is contained in a fibrous or cellular matrix.
