ABSTRACT:
An improved absorbent article includes a layer of absorbent material which has a length, a width and a thickness. Particles of superabsorbent material are distributed within the absorbent material layer, and these superabsorbent particles are disposed to form a substantially continuous, non-step-wise, positive concentration gradient of superabsorbent through at least a portion of the thickness of the absorbent layer.
