Abstract (en)

A process for protecting a dyed textile fiber from decolorization caused by exposure to bleach, and improving colorfastness is provided by applying an aqueous solution of non-volatile, polymeric salt forming monomers, such as hexamethylenediamine and adipic acid, to the textile fiber followed by drying the fiber to polymerize the monomers and form a non-volatile, polymeric salt film thereon. The process is especially suitable for treating dyed polyamide fiber used in floor covering products.
