Abstract
A method for anti-stain treatment of fabric is disclosed. The method for anti-stain treatment of fabric includes: immersing fabric in an aqueous solution containing a telomerized perfluoroalkyl acrylate copolymer, and a crosslinking agent, such as an isocyanate crosslinking agent; dehydrating the immersed fabric; drying the dehydrated fabric; heat treating the dried fabric; and coating the heat-treated fabric with a flame retardant, such as an acrylic flame retardant, to provide flame retardancy. The method provides a car seat fabric having superior stain resistance, water repellency and oil repellency without degradation of other properties required for the car seat fabric, such as flame retardancy, lightfastness, frictional coloration, or the like. The method is widely applicable to commercially applicable car seat fabrics, including flat woven, flat tricot, double raschel, or the like.
