In order to solve the pollution and unsafe problems of chemical dyeing of immortal flowers,optimize the dyeing process of natural plant dyeing immortal flowers,and improve the dyeing effect,fresh roses were used as test materials and natural purple sweet potato pigment was used as dye,and the experiment of dyeing rose immortal flow-ers with purple sweet potato pigment was carried out by single factor test and response surface method,and the dye-ing process of rose immortal flowers was optimized by measuring the material composition of natural purple sweet po-tato pigment and the observation and evaluation of the color characteristic values and appearance traits of rose im-mortal flowers before and after dyeing.The results showed that the optimal process for the direct dyeing of rose im-mortal flowers with purple sweet potato pigment was pH 5,dye concentration 2.0%,dyeing temperature 20℃,dye-ing time 6 h,and mordant color fixing process was 3%copper sulfate,which was dyed with mordant for 3 h.Under these conditions,the dyeing efficiency of rose immortal flowers was the highest,and the appearance and shape of the flowers were better,which had better ornamental value.
