摘　　要：选用光稳定剂与耐晒分散染料安诺可隆蓝HRD 同浴上染涤纶超细纤维织物, 比较染料和光稳定剂的 上染率及染色性能, 探讨两者的相互影响, 并优化光稳定剂用量、复配比例、上染温度、时间等同浴染色工艺,以改善 染色织物的耐光色牢度.结果表明： 光稳定剂与耐晒分散染料同浴上染涤纶超细纤维织物时存在一定竞染, 两者的上染率比单独上染时略有下降; 光稳定剂对织物的色光和染色均匀性基本无影响, 且能在一定程度上提高染色织物 的耐光色牢度.当同浴染色保温温度在130℃ , 染色时间30 min, 紫外线吸收剂UV-531与受阻胺光稳定剂LS-770 复配比mUV-331： MLS-77n为2：1, 用量为2.0% （owf）时提升效果最佳, 能将涤纶超细纤维染色织物的耐光色牢度提高1级.Light stabilizer and lightfast disperse dye HRD were selected for dyeing of superfinepolyester fiber textiles in one bath. The dye-uptake rate and dyeing property of light stabilizer and dyewere compared,and the interaction between the two was discussed. Meanwhile, light stabilizer dosage,compound ratio, dyeing temperature and time etc, were optimized to improve color fastness to light of textil3es. The experiment shows that mixing dyeing exists when the dye and light stabilizer are used in onebath ;the up-take rate of the two decreases, compared to dyeing with single. Light stabilizer has little effect on shade and the dyeing uniformity and can improve the color fastness to light to some extent. The improvement effect is optimal under the following conditions： dyeing temperature 130℃ , dyeing time 30min,compound ratio of the UV absorber UV -531 and hindered amine light stabilizer LS -770 2 ： 1 , dosage 2. 0 % （owf）. Under such conditions, the color fastness to light of superfine fiber textile canimprove by 1 grade.
