Abstract

The pad of the invention is composed of impervious backing sheet and a pervious body-side liner with an absorbent material there between. The pad is elasticized along its edges from points at substantially one end extending along the longer edges of the rectangular pad for at least two-thirds of the length of the pad. In a preferred form of the invention the pad has as its absorbent material a coform structure of air-formed meltblown polymers combined with air-formed cellulose fibers that have been formed onto a pervious spunbonded material that serves as the pervious body-side liner. In the preferred form the backing sheet is formed of an extrusion-coated spunbonded material that has the spunbonded material on the outer surface with the backing sheet folded over to overlap on the body side of the garment with the fabric toward the body. The folded portion forms the pad's baffles. Further, the preferred pad has length of between about 8 and 14 inches, and the width is preferably about 30 percent of the length.
