Body-Fluid Absorbent Panel For Sanitary Wearing Article

May 24, 2005

A body fluid absorbent panel for a sanitary wearing article comprising a fibrous web having a compression resilience has been patented. The fibrous web comprises a number of openings extending therethrough in a direction of a thickness of the fibrous web and barriers surrounding and defining the openings. The barriers comprise a shape-holding layer formed from a plurality of thermoplastic synthetic resin fibers that are hot-welded together at contact points between the thermoplastic synthetic resin fibers to resist collapsing under pressure and a body fluid retaining layer placed upon one of an upper surface and a lower surface of the shape-holding layers and formed from a plurality of thermoplastic synthetic resin fibers which are mixed with an absorbent material and are hot welded together at contact points between the thermoplastic synthetic resin fibers so as to resist collapsing under pressure. The shape holding layer and the body fluid retaining layers have surface pattern configurations defined by the barriers and exclusive of the openings with surface pattern configurations that are substantially coextensive. The thermoplastic synthetic resin fibers of the shape holding layer are hot welded together at contact points thereof in the shape holding layer. The thermoplastic synthetic resin fibers of the body fluid retaining layer are hot welded together at contact points thereof in the body fluid retaining layer and the thermoplastic synthetic resin fibers of the shape holding layer and the thermoplastic synthetic resin fibers of the body fluid retaining layer are hot welded to each other along an interface at contact points of the shape holding layer and the body fluid retaining layer.
