Wool top dyeing cleaner production method

The invention discloses a wool top dyeing cleaner production method, and belongs to the field of wool dyeing. The method comprises the following steps: A, pre-treating wool fibers by polyethylene glycol and biological protease; and B, with bionic acid as a pH (potential hydrogen) adjusting solution, carrying out the dyeing treatment. Compared with the prior art, the wool top dyeing cleaner production method has the advantages that through carrying out the pre-treatment by using the polyethylene glycol and biological protease, the even dyeing of the dye is enhanced, and meanwhile, the dyeing time is further shortened and the dyeing temperature is reduced; through replacing a volatile acetic acid by the bionic acid, the difficulty in processing environment corrosion, air pollution and dyeing wastewater caused by a dyeing process is reduced, and therefore the wool top dyeing clear production method has excellent popularization and application values.
