A method for applying multiple polymeric coatings onto a fibrous substrate. More particularly, a method for applying multiple polymeric coatings onto fibrous substrates without regard to chemical or physical incompatibilities of the polymeric coating materials. A first polymeric material is applied onto at least one fibrous substrate, and a second polymeric material is applied onto a support. The fibrous substrate and support are joined, contacting the first polymeric material with the second polymeric material, followed by separating the support from the fibrous substrate, such that at least a portion of the second polymeric material remains on the first polymeric material on the fibrous substrate.
L'invention concerne un procédé pour appliquer de multiples revêtements polymères sur un substrat fibreux, plus particulièrement un procédé pour appliquer de multiples revêtements polymères sur des substrats fibreux indépendamment d'incompatibilités chimiques ou physiques des matériaux de revêtement polymères. Un premier matériau polymère est appliqué sur au moins un substrat fibreux et un second matériau polymère est appliqué sur un support. Le substrat fibreux et le support sont joints, en mettant en contact le premier matériau polymère avec le second matériau polymère, suivi par une séparation du support du substrat fibreux, de telle sorte qu'au moins une portion du second matériau polymère reste sur le premier matériau polymère sur le substrat fibreux.
