Fibers, textiles, and leather are treated by applying to the fibers, textiles, and leather 0.1-15 weight percent based on the weight of the fibers, textiles, or leather of a treatment composition. The treatment composition consists of a blend containing a silicone resin component and a fluorocarbon component. The fluorocarbon component can be at least one of an emulsion containing a fluoroalkyl acrylate copolymer or an emulsion containing a fluorinated polyurethane. The silicone resin component is at least one of (i) an aminofunctional silicone resin, (ii) an emulsion containing an aminofunctional silicone resin, (iii) a carbinol functional silicone resin, (iv) an emulsion containing a carbinol functional silicone resin, (v) an epoxy functional silicone resin, or (vi) an emulsion containing en epoxy functional silicone resin.
