Patent

CA 2159500

The invention is a stretchable layered fabric laminate which is air impermeable and waterproof while being permeable to water vapor. The stretchable fabric laminate includes a stretchable composite material layer consisting of a hydrophobic protective layer of a porous polymeric material on each side of a layer of hydrophilic water-vapor-permeable synthetic polymer. The composite material layer is laminated to at least one layer of stretchable fabric. The stretchable layered fabric laminate has excellent stretch and recovery properties in both machine and transverse directions, and is useful for the manufacture of form-fitting articles of protective clothing and other end uses.

L'invention se rapporte à un stratifié textile en couches, extensible, qui est imperméable à l'air et étanche à l'eau tout en étant perméable à la vapeur d'eau. Le stratifié textile extensible comprend une couche de matériau composite extensible composé d'une couche protectrice hydrophobe d'un matériau polymère poreux se trouvant de chaque côté d'une couche d'un polymère synthétique hydrophile, perméable à la vapeur d'eau. La couche de matériau composite est contre-collée sur au moins une couche du tissu extensible. Le stratifié textile en couches, extensible, a d'excellentes propriétés d'étirement et de récupération, à la fois dans le sens travers et dans le sens de production, et est utilisé dans la fabrication de vêtements de protection épousant la forme du corps et autres utilisations finales.
