Beschreibung
Zusammenfassung:The present invention provides a hydophobic, oleophobic and stain resistant fabric comprising a woven, non-woven, or knitted fabric substrate coated with a polymer system comprising a scrub resistant first layer at least partially penetrating the fabric substrate, the scrub resistant first layer including a polymer composition containing polymer compositional constituents similar to constituents on the fabric substrate; and a second layer comprising a fluoropolymer reacted to the surface of the scrub resistant first layer. A method for producing a hydophobic, oleophobic and stain resistant fabric including the steps of selecting a suitable fabric substrate and applying a base coating to form a scrub resistant first layer at least partially penetrating the fabric substrate; drying and curing the scrub resistant first layer; applying a fluoropolymer coating over the first layer to form a second layer; and drying and curing the second layer.
