[Methods]Three factors affecting dyeing were selected including pH,concentration of dye and dyeing time. The L_9(3~3) orthogonal design was used to evaluate the hair coloring effect and the absorbance of cleaning solution after hair was dyed. [Results] The optimum pet dog dyeing process of plant hair dye was dye concentration of50 mg/mL,dye pH of 7. 5 and dyeing time of 1 h. [Conclusions] The coloring and fixing effects of the dye and dyeing process are good,which can lay a foundation for the development and utilization of plant dyes.展开更多
