摘要： A multilayer nonwoven structure is described where the nonwoven structure comprises at least two spun bond layers and at least one easily meltable layer. The easily meltable layer is located between the at least two spunbond layers. The easily meltable layer is comprised of a polymer having a melting point at least 20° C. less than the melting point of the polymer which comprises the surface of the fibers which comprise the spun bond layer, or is made from a polymer which is readily absorbs some form of radiation. Under bonding conditions, the fibers which make up the easily meltable layer can be melted to form a film, thereby improving bather properties of the nonwoven structure.
