The invention discloses a dyeing process of basolan wool, and belongs to the technical field of printing and dyeing. The effective process concretely comprises the following steps: yarn is hanged andplaced in a cylinder; yarn is washing; a reactive dye and an auxiliary agent are added; heating is carried out and dye is uptaken; insulation is carried out and yarn is taken out of the cylinder. Theprocess has the beneficial effects as follows: (1) by means of heating and washing of the yarn, the yarn is soaked, dyeing effects of later dyeing are improved, and the phenomenon of colored spots onthe yarn rarely appears; (2) when the material is added, temperature of clear water is controlled, the phenomenon that the surface of the yarn appears larger color difference or colored spots is reduced, and integral quality and beauty of the basolan wool product are improved; (3) while heating is carried out and dye is uptaken, after the temperature is heated to 85 DEG C, color of dye water is observed, heating speed is properly adjusted, reaction speed is accelerated, and dyeing efficiency is improved.
