A disposable multi-layer diaper of high absorptive capacity is provided which comprises as a first layer, a porous facing web to be brought into contact with an infant's skin. A second layer, in juxtaposition to the facing layer, is a highly porous, loosely compacted cellulosic batt having greater wettability than that of the facing web. The batt is slightly narrower than the facing layer to provide exposed side portions of the facing layer outwardly of the side edges of the batt. A third layer integral with the second is a continuous, paper-like, densified highly compacted layer of the same cellulosic material as the second layer but of substantially smaller average pore size. The densified layer is bounded by transverse linear areas near the ends of the batt in which areas the densified layer is thickened. The final layer is an impervious backing sheet that is substantially coextensive with the facing layer and which is adhered to the densified layer. n In a preferred embodiment, the densified layer is thickened longitudinally (as well as in the transverse linear areas) in selected areas to provide an increased volumetric flow capacity for rapidly drawing fluid away from an initially wetted area and directing it to areas of the densified layer remote from the wetted area. |
