<p num="1"><br/><br/><br/><br/><br/> ABSTRACT OF THE DISCLOSURE<br/>Nylon carpet fibers are provided which resist staining<br/>by acid dye colorants at room temperature, yet are dyeable at<br/>elevated temperatures with acid dyes without losing their<br/>resistance to acid dye colorants at room temperature. The fibers<br/>are characterized by having a coating on the surface thereof<br/>comprising one or more selected compounds (stain blockers).<br/>Carpets comprising the fibers resist staining when exposed for<br/>long periods of time to spills containing acid dye colorants. By<br/>also including a fluorochemical in the coating, the carpets can<br/>resist such staining even after being subjected to heavy human<br/>trafficking.<br/> |
