Abstract
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.
