    Abstract: The invention relates to an improvement in certain processes for continuously dyeing polyamide carpets whereby stain resistance is imparted to the carpets during the dyeing process. The improvement involves adding an alkali metal silicate (e.g. sodium meta silicate) and a sulfonated phenol-formaldehyde condensation product to the dye liquor used in the dyeing process. If either the silicate or condensation product is omitted from the liquor, the improvement is not achieved. The improvement provides a convenient and economical means for providing stain resistant polyamide carpets.

    Abstract: Nylon carpet fibers are provided which resist staining by acid dye colorants at room temperature, yet are dyeable at elevated temperatures with acid dyes without losing their resistance to acid dye colorants at room temperature. The fibers are characterized by having a coating on the surface thereof comprising one or more selected compounds (stain blockers). Carpets comprising the fibers resist staining when exposed for long periods of time to spills containing acid dye colorants. By also including a fluorochemical in the coating, the carpets can resist such staining even after being subjected to heavy human trafficking.
