Fabrics, such as carpets, comprising a primary backing and tufts, which are loops and/or cut loops of nylon filaments of fiber blends containing such filaments, the tufts adhered to the primary backing by means of an adhesive are disclosed. The filaments are coated with a stain-resist composition and the adhesive contains a stain-resist composition which may or may not be the same as the stain-resist composition applied directly to the nylon filaments. Suitable stain-resist compositions include those containing condensation products of formaldehyde and sulfonated phenol or sulfonated naphthols, and addition polymers of methacrylic acid or maleic anhydride (which can be hydrolyzed to maleic acid and, if desired, isomerized to fumaric acid) and up to 70 weight percent of another monomer having ethylenic unsaturation and containing 2 to 20 carbon atoms. Blends of the condensate stain-resist composition and addition polymer stain-resist compositions may be used. Optionally, a soil-resist composition such as a fluorocarbon may also be used in the adhesive in combination with the stain-resist composition. The fabrics exhibit improved stain-resistance after washing compared with similar fabrics in which the stain-resist composition is applied to the nylon filaments and is not present in the adhesive. |
