Abstract
A disposable absorbent product, such as a urinary pad, comprises a liquid-impermeable, substantially flexible shell, an absorbent core and a liquid permeable facing adhered to the shell so as to enclose the absorbent core therein. The absorbent core comprises at least one layer of tenderized peat moss, each such layer being cut adjacent to each lengthwise edge in one or more slits so as to aid lateral compression folding of the sheet, and, adjacent to the layer of peat moss, a receiving layer of an absorbent cellulosic material. The absorbent core has an M-fold configuration and comprises a longitudinally extending channel for receiving discharged liquid.
