ABSTRACT:
Fiber products of a blend of an acrylic fiber substantially free of acid dye sites with an acid dyeable fiber are printed with a dye paste containing a monosulfonic acid dye having an inorganicity/organicity ratio less than 4 to dye both fibers of the blend uniformly. As an alternative an additional acid dye outside the specific class designated may be used to augment the dyeing of the acid dyeable fiber.
