Abstract
A corrugated disposable diaper is provided. The diaper has an initially molten liquid-impermeable film as the liquid barrier backing to which is laminated a loosely-compacted cellulosic fibrous batt and a liquid-permeable facing. Multiple strands of elastic are laminated between the initially molten film and a backing fabric in a transverse direction so as to corrugate the fibrous batt and provide a corrugated disposable diaper with longitudinal corrugations.
