【摘要】 将稀土-柠檬酸配合物应用于纯棉织物活性染色中,讨论了染色工艺和稀土-柠檬酸配合物、元明粉、代用碱用量对染色效果的影响。结果表明,稀土-柠檬酸配合物具有明显的促染作用,染色深度可提高15%~20%,并减少30%元明粉用量;使用代用碱SA-RCF固色,可提高稀土-柠檬酸配合物在染色中的稳定性,上染率和固色率大幅提高。与常规染色织物相比,稀土-柠檬酸配合物活性染料染色织物的匀染性略差,除钇-柠檬酸配合物外,色差变化不明显,耐摩擦色牢度和耐皂洗色牢度基本一致,耐光色牢度略有提高。更多还原

【Abstract】 Rare earth-citric acid complexes are applied to reactive dyeing of cotton fabric.The influences of dyeing process and dosages of rare earth-citric acid complexes,sodium sulphate and substitute alkali on dyeing results are discussed.The results show that rare earth-citric acid complexes have obvious accelerating action in reactive dyeing,and fixation with substitute alkali SA-RCF can improve the stability of rare earth-citric acid complexes.Dyeing with rare earth-citric acid complexes,the color depth increases by 15%-20%,the dye uptake and fixation improves significantly,and the dosage of sodium sulphate reduces by 30%.Compared with traditional reactive dyeings,the dyeings with rare earth-citric acid complexes feature a little reduced evenness,no obvious color deviation except Yttrium-citric acid complexes,almost the same color fastness to rubbing and soaping,and slightly enhanced color fastness to light.更多还原
