Abstract (en)
[origin: WO9215750A1] This invention is a method for dyeing polyamides with water soluble, reactive dyes having the reactive substituent (SO2-Z), wherein "Z" is a fiber reactive group. At least one fiber reactive dye is applied to the polyamide substrate at an acid pH and the dyed substrate is then heated with an alkaline compound and heat to covalent bond the dye to the substrate. The covalently dyed polyamide has superior fastness and overdye properties over polyamide substrates that have been dyed using acid dyes.
