Absorbent structure containing corrugated web layers

An absorbent product comprising a first layer and a second layer, said second layer being substantially united to said first layer and substantially coextensive therewith, said first layer comprising a fibrous web of synthetic resilient fibers said web having a dry bulk of at least about 10 cc per gram and a weight less than about 4 ounces per square yard, said second layer comprising frictionally engaged hydrophilic particles selected from the group consisting of cellulosic fibers, peat moss, rayon fibers, acrylic fibers and mixtures thereof, said first and second layers being corrugated and stabilized to retain the corrugated form even when wet.

A disposable diaper containing an absorbent pad wherein said absorbent pad is an absorbent product comprising a first fibrous layer of synthetic resilient fibers in the form of a nonwoven web and a second layer substantially united to said first layer, said second layer having a higher capillary pressure than said first layer to provide preferential attraction and wicking of liquid in said second layer, said layers being corrugated to provide a corrugated structure, said corrugated structure being stabilized to retain its corrugations when wet.
