Phellinus igniarius pigment dyeing method of silk fabric

The invention discloses a phellinus igniarius pigment dyeing method of silk fabric. Specifically, the method includes the following steps of adding phellinus igniarius pigment to water according to the ratio of the phellinus igniarius pigment to the silk fabric to the water being (0.01-0.03g):1g:(40-60mL), adjusting the pH value to be 2-4 to obtain a dyeing solution, adding the silk fabric to the dyeing solution to be dyed for 60-180 min at a temperature of 70-90 DEG C under the existence of a mordant, namely misch metal with concentration of 0.5-2.5 g/L, and finally obtain the silk fabric dyed by the phellinus igniarius pigment. The phellinus igniarius pigment is used for the first time for dyeing the silk fabric, and the application range of phellinus igniarius is widened; the dyeing technology using natural dyes has the advantages of being biodegradable, high in environment compatibility and the like; the general defect that natural dye is poor in color fastness is overcome; the technology has the advantag
