Patent number: 8480840Abstract: A stretch composite having one or more elastomeric members disposed on at least one region of an extensible fibrous substrate to provide stretch properties to a targeted region of the substrate. 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 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 stretch composites.Type: GrantFiled: October 6, 2006Date of Patent: July 9, 2013Assignee: The Procter & Gamble CompanyInventors: Fred Naval Desai, Urmish Popatlal Dalal, Mark William Hamersky, Steven Daryl Smith
