Abstract: A dyeing method includes immersing a fiber into a dye for dyeing the fiber, in which the dye includes indigo and indirubin, and the indigo and the indirubin have a weight ratio of 20:1 to 80:1. The indigo in the dye has a concentration of 0.1% o.w.f. to 5% o.w.f. The dyed fiber may simultaneously have high luminance, high color saturation, high strength of colorization, and sufficient colorfastness.
