ABSTRACT:
A surprising improvement in dye-lightfastness of dyed nylon automotive fabrics is achieved by a combination of a copper salt and of an oxanilide light stabilizer. The oxanilide is effective with a surprisingly broad range of copper derivatives. Both the copper and the oxanilide may conveniently be applied from the dyebath, or, surprisingly, the copper provides improvements even if melt-spun into the fiber.
