摘要： Filtration media for filtering a liquid includes a plurality of fibers having a coating thereon of a fluorine containing compound. Also disclosed are processes for forming fibrous non-woven liquid filtration media having the coating of the fluorine containing compound. Suitable fluorine containing compounds generally include fluoropolymers, fluorinated hydrocarbons, fluoroacrylate polymers, and the like. The liquid filtration media having the coating of the fluorine containing compound provides markedly improved dirt holding capacity and efficiency properties, among others.
