Abstract: The disclosure provides a dyeing method using bio-dye. A first compound containing an X group is reacted with a second compound containing a Y group to form a third compound, in which the X group is selected from the group consisting of an isocyanate group, a carbodiimide group, an aziridinyl group and an epoxy group, the Y group is selected from the group consisting of a hydroxyl group and an amine group, and the second compound is an amine compound and contains two or more Y groups. Cationization of the third compound is carried out with a fourth compound containing a carboxyl group to form a cationic modification agent. A cationic modification treatment is performed on a fiber material by using the cationic modification agent to form a cationized fiber material. Thereafter, a dyeing treatment is performed on the cationized fiber material through a dye solution containing bio-dye to color the cationized fiber material.

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.
