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.
Claims1
An improved dyed nylon fabric that is suitable for use in automotive upholstery, and is provided with dye-lightfastness by the presence of a cupric salt, the improvement being characterized by the presence of oxanilide, in addition to the cupric salt.
