A new-style fluorine-containing polymer with short chain was synthesized. The fabrics were finished with polymer emulsions with different contents of fluorine. The performances of the polymers were compared with two kinds of similar products, which contained water repellency, oil repellency, contact angle, brightness, and etc. The type of monomer was determined with infrared spectrum. The variety of micro-morphologic structure of cotton fabrics before and after the finishing was studied with SEM, XRD, and etc. It showed that the polymer was copolymerized by three kinds of acrylic ester monomers, and the application performance was in general accord with the same kind of advanced products of the world.
