In response to the problem of poor wet treatment and color fastness to sunlight in natural dye printing,chestnut shell pigment was selected as the research object to explore the impact of alum pre mor-dant dyeing printing process on printing performance.The results showed that when the pre mordant alum dosage was 6%(omf)and the printing steam condition was 102℃saturated steam for 45 min,the color fast-ness of chestnut shell pigment printed silk fabric was greater than or equal to level 3-4,meeting the require-ments for wearing textiles.
