Abstract:
An absorbent article comprising:a main body portion having a longitudinal centerline defining a longitudinal direction, a lateral centerline perpendicular to said longitudinal centerline defining a lateral direction, substantially longitudinally oriented edges and substantially laterally oriented edges, wherein said substantially longitudinally oriented edges and said substantially laterally oriented edges define a periphery for said main body portion and wherein at least one of said substantially laterally oriented edges is wider than the width of said main body portion at a location between said substantially laterally oriented edges, said main body portion comprising:a composite liquid pervious topsheet having a central zone and a pair of longitudinally oriented side zones each said side zone being positioned between said central zone and one of said longitudinal edges of said main body, said composite topsheet comprising:a) a nonapertured nonwoven outer layer which is able to acquire liquids deposited thereon, said nonwoven outer layer having a pair of longitudinally oriented inner edges in a predetermined spaced apart relationship wherein the lateral separation between said inner edges defines the lateral width of said central zone,b) an apertured thermoplastic film layer having longitudinal edges, said apertured thermoplastic film layer being positioned beneath said nonwoven outer layer so that said nonwoven outer layer overlies said apertured thermoplastic film layer in said side zones and said apertured thermoplastic film layer is exposed in at least a portion of said central zone, at least a portion of said thermoplastic film layer being treated with surfactant, whereinc) said nonwoven outer layer and said apertured thermoplastic film layer are joined by a pattern of intermittent fusion bonds;a liquid impervious backsheet associated with said topsheet; andan absorbent core having side edges, said absorbent core being positioned between said topsheet and said backsheet.
