Abstract
Colorfastness of cationic dyeable nylon fibers dyed with acid and/or premetalized acid dyes is enhanced and potential water bleed problems can also be overcome by treating the dyed fibers with an acrylic water bleed fixative in conjunction with a traditional cotton water bleed fixative. In a typical procedure, the acrylic fixative is applied first, followed by the nylon fixative or the cotton fixative.
