ABSTRACT OF THE DISCLOSURE A disposable diaper comprising in order: a water-pervious layer; a spongy, resilient and compressible hydrophobic fibrous layer; and absorbent core; and a water impervious layer, wherein said hydrophobic fibrous layer has a density of from about 0.01 gm/cc to 0.03 gm/cc and comprises non-woven, hydrophobic fibers having an average length of from about 1/4 in. to 3 1/2, said fibers being bounded 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 fluid, the compressed fibers inter- meshing to form a seal or barrier.
