Abstract
Abstract A diaper system having an elongate, fluid impervious padretaining garment and an elongate, disposable absorbent pad retained in the garment. The elongate, disposable absorbent pad includes an absorbent layer disposed within a covering envelope, and the covering envelope has a porous facing layer and a backing layer. The absorbent layer includes a fluff batt of cellulosic fibers which is substantially rectangular and which has a forward section with a greater weight of fibers therein than a rearward section. An embossed pattern in the fluff batt includes compressed regions in the form of transversely spaced, elongate channels which extend for substantially the entire elongate extent of the fluff batt for transmitting body fluids in the direction of elongation of the fluff batt, and elongate high loft regions between channels for storing urine in the fluff batt.
