Abstract
Abstract A disposable absorbent pad such as a diaper, sanitary napkin, underpad, surgical dressing or wipe, and the like, is made from a flexible, body fluid-impermeable backing sheet, a layer of absorbent material on the backing sheet, and a soft, body fluid-permeable facing sheet which overlies the absorbent material. The facing sheet is a perforate, substantially hydrophobic thermoplastic web having an integral fibrous or sueded outer surface. In addition to being useful as a separate entity the absorbent pad of this invention can also be incorporated into a disposable or limited use garment as an integral part thereof.
