5. After dyeing, it can be oxidized by air, or it can be oxidized by hydrogen peroxide or sodium perborate. The color of the dye is bright blue green. It can improve the light fastness and resistance by using copper sulfate or sodium dichromate and acetic acid in the same bath. Wash fastness, the color is blue and deep.
