摘　　要：采用高碘酸钠选择性氧化制备双醛基壳聚糖,并用于毛织物的姜黄色素染色,以实现染色增深、交联固色,同时赋予毛织物抗紫外线和耐久性的目的。双醛壳聚糖预处理毛织物的姜黄染色优化工艺为:双醛壳聚糖质量分数1%,焙烘温度125℃,焙烘时间2.5 min,染浴pH为5时,毛织物的K/S值为14.361,耐皂洗和耐摩擦色牢度为3-4级,染色固色效果优于同浴法,且染后毛织物的UPF值为50+。Dialdehyde chitosan is prepared by selective oxidation with sodium periodate and is used in the cur⁃cumin dyeing of wool fabrics to achieve shade deepening,UV resistance and durability.The optimized turmeric dyeing process of wool fabric pretreated with dialdehyde chitosan is as follows:dialdehyde chitosan 1%,baking temperature 125℃,baking time 2.5 min,pH 5 of dyeing bath.Wool fabric with the above process features good properties of 14.361 of K/S value,Grade 3-4 of color fastness to soaping and rubbing,and 50+of UPF,which are better than those with one-bath dyeing.
