Title:
Elastic laminated fabric material and method of making same
Document Type and Number:
WIPO Patent Application WO1998029241
Kind Code:
A3
Abstract:
A laminate material formed of an elastomeric polymer sheet and a nonwoven fabric sheet. The sheets are passed through a niproll assembly during lamination, one of the niprolls having a series of embossing points protruding therefrom, and the other niproll being substantially flat. The embossing points press selective areas of the preferably molten polymer sheet into the fabric sheet, encapsulating the fabric fibers and bonding thereto. The resulting material has points of bonding where penetration has occurred and areas of nonpenetration, providing adherence of the two sheets while permitting independent movement of the fibers and elastic properties. Preferably, a release agent is added to the elastomeric polymer to reduce the possibility of the elastomer layer sticking to the nonwoven layer when the laminate is wound onto a supply roll.
