摘　　要：采用降解壳聚糖对桑蚕丝绸进行预处理,利用植物染料苏木对处理后的丝绸进行染色。通过单因素实验,确定降解壳聚糖预处理桑蚕丝绸苏木染料染色的最佳工艺为:降解壳聚糖质量分数80%,苏木提取液质量分数90%,90℃染色40min。经上述工艺处理后,桑蚕丝绸染色牢度提高,染色深度增加。In this paper,low molecular weight chitosan was used as pretreatment to mulberry silk and then dyed with sappanwood natural dye.Through single analysis method,the optimum process of dyeing was degraded chitosan concentration 80%,dyeing solution concentration 90%,dyeing temperature 90℃and dyeing time 40 min.The fastness and color of mulberry silk after treating were all increased.
