ABSORBENT ARTICLE WITH IMPROVED LAMINATE TOPSHEET
An absorbent article having a topsheet of particular configuration and composition is disclosed. The topsheet may be a laminate web having an upper layer of polymer film, directly bonded to a lower layer of nonwoven web. The film may include predominantly polyethylene (PE), have a basis weight of 8-20 gsm, and have formed thereon a pattern of cones and valleys, the cones projecting upwardly from adjacent valleys to rim edges proximate an upper side of the laminate web, the cones circumscribing and defining apertures through the film. The nonwoven web may have a basis weight of 12-24 gsm, and include staple fibers, with randomly-distributed fiber-to-fiber fusion bonds thereamong. The staple fibers may have an average denier of 3-12, and be spun of one or more polyolefins. Each of the film and the staple fibers may be modified with one or more hydrophilizing agents.
