摘　　要：针对天然染料上染棉织物过程中存在不易染深色,且染色牢度差等问题,采用正交试验法和单因素试验法,研究高粱壳色素对壳聚糖预处理棉织物染色性能的影响,优化了预处理工艺,测试了染色织物的颜色特征值及色牢度。结果表明,壳聚糖对棉织物进行预处理,当预处理温度为70℃,时间为30 min,壳聚糖质量浓度为8 g/L,p H值为5时,高粱壳色素染色棉织物的K/S值最大为6.8。染色棉织物的皂洗牢度和摩擦牢度均达到4级以上,比未处理织物提高了1级。In order to solve the problems including difficult to dye dark shade and poor color fastness in cotton dyeing with natural dyes, the effect of chitosan pretreatment on dyeing property of cotton fabric with sorghum husk colorant is investigated by orthogonal test and single factor test. The pretreatment conditions are optimized, the colorimetric data and color fastnesses of the dyed fabric are measured.The results show that K/S value of the cotton dyeings pretreated with chitosan increases to6.8, under the conditions of chitosan 8 g/L, p H value 5, pretreating at 70 ℃ for 30 min. Moreover, the color fastnesses to soaping and rubbing of the cotton dyeings are improved to above Grade 4.
