Abstract
Absorbent panel structures that comprise a unitary pulp panel having a forward section and a rearward section, the rearward section comprising from about 20% to about 70% of the rearward panel length. One or more longitudinally elongated areas or grooves of reduced thickness and basis weight are formed in the panel. The rearward section preferably has a mean basis weight that is from about 30% to about 70% less than the mean basis weight of the forward section of the panel. The thickness of the elongated areas may be uniform along the length of the panel or may decrease along the panel length direction from the front edge to the rear edge. Superabsorbent particles may be uniformly dispersed throughout the panel or may be dispersed in longitudinal stripes that may or may not coincide with the elongated areas.
