Abstract
An absorbent article having improved strikethrough, rewet characteristics, and feel is disclosed. The absorbent article has a topsheet comprising a nonwoven material and apertured thermoplastic film. The apertured thermoplastic film is treated with a surfactant preferably by incorporating the surfactant into the resin used to make the thermoplastic film. The combination of the nonwoven material and the surfactant-treated apertured thermoplastic film permit liquids to rapidly penetrate the topsheet while preventing liquid in the absorbent core of the article from flowing back through the topsheet. The nonwoven material provides the topsheet with improved, less plastic-like feel.
