Document Type and Number:
WIPO Patent Application WO2000018994
Kind Code:
A3
Abstract:
The present invention is generally directed to elastic nonwoven webs and films made from thermoplastic polymers. In particular, the present invention is directed to forming nonwoven webs and films from an elastomeric polymer and then cross-linking the polymer in order to improve the stretch characteristics of the article. Cross-linking also makes the article more temperature resistant. In one embodiment, the elastomeric polymer is a metallocene-catalyzed copolymer of polyethylene. Elastic layers made in accordance with the present invention can be combined into laminates and used in various products, such as diapers and other personal care articles.
