Abstract
A method for impregnating a bundle of sized glass fibers with a composition comprising a polytetrafluoroethylene resin, a film-forming acrylic resin, a thickening agent and a polyhydrolyzable organosilane having nonhydrolyzable amine functionality is described. The impregnated bundles are especially suited for at least the warp of fabrics for filtering entrained particulates from gases such as flue gases from the combustion of hydrocarbon fuels such as coal.
