Abstract
A disposable diaper comprising in order: A water-pervious layer; A spongy, resilient and compressible hydrophobic fibrous layer; An absorbent core; and A water impervious layer, Wherein said hydrophobic fibrous layer has a density of from about 0.01gm/cc to 0.03gm/cc and comprises non-woven, hydrophobic fibers having an average length of from about 1/4 in. to 31/2 , said fibers being bonded together at at least a substantial number of their points of contact. The hydrophobic fibrous layer is pervious to fluids in the uncompressed condition; however, when compressed, as by the bodily weight of an infant clothed with the diaper, the layer becomes impervious to fluids, the compressed fibers intermeshing to form a seal or barrier.
