Abstract: A method of imparting stain resistance to colored substrates which include a filamentary material. A first dispersion of a polymer is applied to the filamentary material as a finish during the manufacture of the filamentary material, and a second dispersion of a polymer is applied as an overspray after the filamentary material has been formed into a colored substrate, to achieve at least 300 ppm fluorine from each application on the filamentary material (at least 600 ppm fluorine total). The dispersions are independently selected from the group consisting of i. a first polymer comprising (a) from about 50 to about 85 parts by weight of units derived from a fluorinated monomer or mixture of fluorinated monomers having formula (I); and (b) from about 15 to about 50 parts by weight of units derived from one or more monomers having formula (II); and ii. a dispersion comprising (a) from about 10 to about 50 parts by weight the first polymer; (b) from about 5 to about 10 parts by weight an emulsifier; and (c) from about 40 to 85 parts by weight a second polymer derived from a monomer having formula (III) wherein Rf is straight or branched-chain perfluoroalkyl containing 4-20 carbon atoms; R is H or CH3; n is an integer from 1-15; and X is Cl or Br.
