[Abstract]:The microwave extraction method was used to extract the plant rhubarb and alizarin. By measuring the K / S value of wool dyed with extract solution, the effects of solvent volume fraction, extraction time, temperature and power on the extraction effect were investigated, and the extraction process was optimized. The natural dyes rhubarb and alizarin were used to dye silk fabrics. The effects of dye dosage, dyeing time, temperature and pH value on the dyeing effect were studied, and the dyeing process was optimized. The color blending properties of four kinds of natural dyes were studied. The changes of K / S value and color fastness of dyed wool fiber were studied by using formaldehyde-free fixing agent. The content of anthraquinones in rhubarb extract was determined by HPLC. The results are as follows: the optimized microwave extraction technology of rhubarb and alizarin is: ethanol volume fraction 40%, extraction time 6 min, extraction temperature 90 鈩，
