Un método para formar un material compuesto fibroso, que comprende: a) proporcionar una pluralidad de sustratos fibrosos, en la que cada sustrato fibroso comprende una única fibra; b) aplicar un primer material polimérico sobre una superficie de cada sustrato fibroso; c) aplicar un segundo material polimérico sobre una superficie de un soporte; d) después, juntar los sustratos fibrosos y el soporte poniendo en contacto el primer material polimérico con el segundo material polimérico; e) separar el soporte de los sustratos fibrosos, de manera que al menos una porción del segundo material polimérico permanece sobre el primer material polimérico en los sustratos fibrosos; y f) después, tejer los sustratos fibrosos en forma de un tejido tejido. 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.
