C.I.分散红60及其同系列染料在不同pH染浴中的染色性能

Dyeing Behaviors of C.I. Disperse Red 60 and Its Related Dyes in Dyeing Baths of Different pH

摘要: 在不同ｐＨ染浴中测试了Ｃ．Ｉ．分散红６０及其相关品种（Ｃ。Ｉ。分散红１２７、１４６及１９１）对涤纶织物的染色性能。结果表明，染浴ｐＨ不影响Ｃ．Ｉ．分散红６０、１９１对涤纶织物染色的提升力。中性、碱性染浴下Ｃ。Ｉ。分散红１４６对涤纶织物的染色性能优于酸性染浴。Ｃ．Ｉ．分散红１２７在碱性染浴下对涤纶织物染色的提升力小于中性染浴，在酸性条件下能获得最佳提升力。染浴ｐＨ对上述染料的而晒、耐升华牢度没有影响

Abstract: The dyeing behaviors on polyester textiles (PET) of C.I. Disperse Red 60 and its related dyes such as C.I. Disperse Red 127,146 and 191 were determined in dyeing baths of different pH. The results indicated that pH had no effect on the buildup of C.I. Disperse Red 60 and 191 on PET. The buildup of C.I. Disperse Red 146 on PET in the neutral and basic dyeing baths was superior to that in the acidic dyeing baths. C.I. Disperse Red 127 obtained good buildup on PET in the acidic dyeing baths, while its buildup on PET was worse in the neutral one and was the worst in the basic one. The light fastness and sublimation fastness of C.I. Disperse Red 60,127,146 and 191 on PET had nothing to do with dyeing baths of different pH.
