Abstract
A diffuser layer is interposed between layers of moisture absorbent material situated within a cover sheet. The diffuser layer comprises one or more tissue layers, each having a plurality of parallel corrugations to disperse moisture by capillary action. A compression seal is situated in the cover sheet separating two pad parts. The compression seal comprises first and second crimps, spaced by a section of the cover sheet. The ends of the pad parts are also sealed by crimping. The absorbent material is wood pulp impregnated with a starch polymer or an acrylic-based polymer to increase the absorbency thereof. An agent may be included in the pulp to prevent the biological degradation of urine. Substances may also be included in the pulp for absorbing volatile nitrogenous compounds and odors. In addition, a moisture or chemical sensitive indicator strip may be situated on the cover sheet.
