ABSTRACT:
Hydrofluorosilicic acid and its water soluble salts enhance the stain resistance or acid dye fixation and resistance to cold water bleeding of fibrous polyamide and wool substrates, for example, carpets, treated with a water soluble sulfonated aromatic-aldehyde condensation resins, for example, sulfonated resole and sulfonated novolak type resins; at the same time an improvement in light fastness or non-yellowing is obtained and the durability or wash fastness of the stain resistance is improved; the condensation resin is optionally employed in conjunction with a polymeric methacrylic acid.
