| abstract |
An elastic nonwoven composite is provided that contains an elastic film laminated to one or more nonwoven web materials. The composite is formed by passing the film through the nip to bond the film to the nonwoven web material (s). At the same time as the bond is formed, perforations are also formed in the elastic film. The perforation is of sufficient size to provide the composite with the desired level of texture, softness, hand feel, and / or aesthetic appeal without significant side effects on the elastic properties of the composite. Perforation and bond formation are achieved in the present invention by selectively adjusting certain parameters of the lamination process such as film content, bonding pattern, film tension degree, bonding conditions, and the like.n n n n Nonwoven Web Material, Elastic Nonwoven Composite |
