Abstract
An improved internal wetting agent is provided for blending with polymeric material, with the formation of apertured films and/or polymeric fibrous webs contemplated. Films and/or nonwoven fabrics of this nature are suited for use in disposable absorbent articles, particularly for the so-called topsheet or facing layer, which contacts the wearer during use. Because polymeric materials from which these types of facing layers are made are typically hydrophobic, the provision of an internal wetting agent facilitates the passage of liquid through the facing layer into an associated absorbent structure.
