摘　　要：为了探索天然染料对聚酯纤维染色的可行性,研究了茜草色素的分散性能及其对聚酯织物的染色性能。茜草色素可用复配分散剂分散,优化的分散工艺为分散剂与茜草色素质量比为3∶10,阴离子型分散剂与非离子型分散剂质量比为3∶2,分散时间为60 min;茜草色素分散液对聚酯织物的优化染色工艺为pH=3,染色温度130℃,时间45 min。采用上述工艺染色的聚酯织物具有良好的得色量和匀染性,色牢度均达到4级及以上。此外,染色聚酯织物还具有抗紫外线性能。In order to explore the feasibility of natural dyes for dyeing polyester fibers,the dispersion perfor⁃mance of madder pigment and its dyeing performance on polyester fabrics are studied.The results show that madder pigment can be dispersed with a composite dispersant.The dispersion process is the mass ratio of dis⁃persant to madder pigment of 3∶10,the mass ratio of anionic dispersant to nonionic dispersant of 3∶2,and the dispersion time of 60 min.The optimal dyeing process of polyester fabric with madder pigment dispersion is pH=3,dyeing at 130℃for 45 min.The polyester fabric dyed by the above process has good color yield and levelness,and the color fastness reaches Grade 4 and above.In addition,dyed polyester fabrics also have UV resistance.
