September 5, 2006

A sanitary napkin was patented. It comprises a liquid permeable top layer, a liquid impermeable back layer and a liquid absorbent core between the top and back layers. The top layer has a central zone and side zones at both sides of the central zone. The top layer includes an upper layer of a thermoplastic synthetic resinous material and a lower layer of thermoplastic synthetic fibers that is more hydrophilic than the upper layer but less hydrophilic than the core. The upper and lower layers are intermittently bonded together by thermally embossing the side zones. The central zone is thicker than the side zones.
