The present invention comprises a process for providing soil resistance and resistance to staining by acid dyes to fibers and textiles by simultaneous or sequential application of a sulfonated phenol-formaldehyde condensation product and partial fluoroesters or fluorothioesters formed from copolymers of maleic anhydride and perfluoroalkyl alcohols or perfluoroalkyl thiols.
L'invention comprend un procédé destiné à conférer une résistance aux salissures et aux tâches, à l'aide de colorants acides, à des fibres et des textiles par l'application simultanée ou séquentielle d'un produit de condensation de formaldéhyde-phénol sulfoné et de fluoroesters ou fluorothioesters partiels formés à partir de copolymères d'anhydride maléique et d'alcools de perfluoroalkyle ou de thiols de perfluoroalkyle.
