摘要: 针对毛/丝复合织物一浴一步法染色同色性差的难题,将氧化还原体系低温染色应用到毛/丝复合织物一浴一步法染色中。结果表明:在双氧水与硫脲浓度比为0.045 mol/L∶0.015 mol/L的氧化还原体系下,羊毛织物和蚕丝织物分别用弱酸性染料80℃低温染色,可获得相当于或超过常规沸染工艺的上染率和K/S值;该双氧水/硫脲氧化还原体系可显著改善毛/丝复合纺织物一浴一步法染色的同色性。紫外可见吸收光谱测试显示,在双氧水/硫脲氧化还原体系作用下,染液的色光未发生变化;同时,织物的皂洗及摩擦牢度不受影响。

Abstract: According to the problem of union dyeing of wool/silk blends with one bath and one step dyeing,the low temperature dyeing with redox system was used in the one bath and one step dyeing of wool/silk blends.The results showed,under the redox system of H2O2/NH2CSNH2with the ratio of 0.045 mol/L∶ 0.015 mol/L,wool and silk fabrics were dyed in low temperature dyeing at 80℃with selected weak acid dyes respectively,the dyeing uptakes and the color yieldsK/Svalue of wool and silk fabrics were equal to or exceeded those dyed with normal boiling dyeing condition.The H2O2/NH2CSNH2redox system could improve the union dyeing property of wool/silk blends in the one bath and one step dyeing obviously.The UV and visible spectrum analysis revealed that the color of the dyeing solution was not changed under the redox system,and the washing fastness and rubbing fastness were not influenced either.
