Disposable diaper

Abstract

Abstract A disposable multi-layer diaper of high absorptive capacity and improved feel is provided which comprises as a first layer, to be brought into contact with an infant''skin, a porous, fibrous, nonwoven bonded facing web of controlled wettability made of short cellulosic fibers and long fibers at a given overall concentration. The outer face of the facing layer is characterized by a blend of long and short fibers, with the concentration of long fibers being in excess of the overall concentration, while the inner face of the facing layer is also characterized by a blend of long and short fibers, with the concentration of short fibers being in excess of the overall concentration. The outer face of the facing layer has a sufficient amount of long fibers to give the diaper improved feel and wearing characteristics. The concentration of short cellulosic fibers gradually, and preferably substantially uniformly, increases from the outer face to the inner face of the facing layer to provide a gradually increasing degree of wettability for preferentially drawing the urine away from the outer face, through the facing layer and into a second layer, in juxtaposition to the facing layer. The second layer is a highly porous, loosely compacted completely cellulosic batt having greater wettability than that of the facing web. A third layer, integral with the second, is a paper-like, densified, highly compacted layer of the same cellulosic material as the second layer but of substantially smaller average pore size and which is selectively thickened in certain areas. The final layer is an impervious backing sheet adhered to the densified layer over a widely distributed area of adhesion.
