Abstract

The invention discloses a pearl dyeing method belonging to the technical field of pearl dyeing. The method comprises the following steps: (1) preliminary treatment of a pearl: soaking a cleaned pearl in oxydol for 12-24 hours, transferring into anhydrous alcohol to carry out first dehydration, and then replacing the anhydrous alcohol once; (2) preparation of a dyeing liquid: preparing water, anhydrous alcohol and anhydrous methanol into a solvent according to a volume ratio of 2-6:3-5:1-5, and adding dye, potassium iodide and surfactant to the solvent; and (3) dyeing of the pearl: impregnating the pretreated pearl in the prepared dyeing liquid, dyeing at a constant temperature of 45 DEG C for 3-7 days, and airing after cleaning to obtain a finished product. The invention has the advantages of uniform dyeing and delicate and bright color.
