Abstract
A composite nonwoven fabric is provided for use as a one-piece topsheet and barrier fabric for disposable absorbent articles including diapers, catamenial products, and adult incontinence products. The fabric is engineered to have a strikethrough region that is normally surfactant treated for receiving insults and transporting them to an absorbent core material for storage. The strikethrough region is bounded by liquid barrier regions that are suitable for defining containment structures, including diaper leg cuff. The barrier and strikethrough regions can be designed to have excellent low rewet characteristics and to have balanced properties comparable to or better than conventional spunbonded topsheet at comparable or lower basis weights.
