Abstract:
Variable stretch composites having one or more first elastomeric members disposed on a first region of an extensible substrate, and one or more second elastomeric members disposed on a second region of the extensible substrate which different from the first elastomeric members to provide variable properties to said regions of the composite. The composite has been incrementally stretched to at least partially break up the structure of the substrate in order to reduce its resistance to stretch. The variable stretch composites are useful for disposable and durable articles, such as disposable absorbent articles including diapers, pull-on diapers, training pants, incontinence briefs, catamenial garments, baby bibs, and the like, and durable articles like garments including sportswear, outerwear and the like. The present invention also relates to methods of forming such variable stretch composites.
