摘要
初步研究了酸性染料混拼染色锦纶地毯纱时对地毯纱耐光色牢度的影响，通过在染色时添加助剂考察其对改善耐光色牢度的作用，比较了助剂种类、质量浓度、染色温度及时间对染色K／s值和耐光色牢度等染色性能的影响．用正交试验优化了染色工艺．研究结果显示：用天龙染料混拼染色锦纶地毯纱，其耐光色牢度比较差，三拼染色时仅为2级；日晒牢度增进剂A可提高三拼染色时地毯纱的耐光色牢度，其最佳工艺为：日晒牢度增进剂A的质量浓度5．0g／L，染色温度90℃，染色时间60min，获得的耐光色牢度达到3～4级．
The impact of the light fastness on PA carpet yarn dyed with acid dyes combination was studied. Anti-UV auxiliaries were used in dye bath to improve the light fastness. The effects of different auxiliaries and dyeing conditions were explored on the K/S value and the light fastness etc. Additionally, the dyeing process was optimized by the orthogonal test. The results showed that the light fastness of PA carpet yarn dyed by Telon dyes mixtures was unsatisfactory. The light fastness was only grade 2 when PA carpet yarn was dyed by three dyes mixture. Light fastness improver could improve the light fastness of dyed PA carpet yarn. The optimize process of the combination dyeing was defined as follows ： the usage of light fastness improver was 5.0 g/L, the temperature was 90 ℃ for 60 minutes, in which the light fastness reached 3 - 4.
