摘要/Abstract

摘要： 为提高活性染料染色丝绸的固色率和降低促染剂用量，研究了双辛基二甲基溴化铵（DODMAB）作促染剂对三支活性染料在丝绸上的促染规律。结果表明：DODMAB对活性染料上染丝绸具有高效的促染作用,促染剂质量浓度在4g/L时，活性红B-3BF、活性黄B-4RFN、活性深蓝B-2GLN上染率分别达到了98.7%、95.32%、94.96%，固色率分别为96.3%、89.18%、90.28%;三支活性染料染色丝绸的皂洗牢度均达到4-5级；三支活性染料在丝绸上的吸附动力学均符合准二级动力学模型。

Abstract: In order to increase fixation rate of reactive dyeing silk and reduce the accelerant , with dioctyl dimethyl ammonium bromide (DODMAB) as accelerant, accelerating rule of dyeing silk with three reactive dyes was studied in this paper. The results showed that DODMAB was a high effective accelerant on dyeing silk with reactive dyes. When the concentration of DODMAB was 4 g/L, dye uptake rate of Reactive Red B-3BF, Reactive Yellow B-4RFN and Reactive Dark Blue B-2GLN reached to 98.7%, 95.32% and 94.96%, and fixation rate was 96.3%, 89.18% and 90.28%, respectively; Soaping fastness of reactive dyeing silk was 4-5 degree; The adsorption kinetic of three reactive dyes on silk with DODMAB as accelerant was found to follow the pseudo second-order kinetic model.

Key words: dioctyl dimethyl ammonium bromide, reactive dye, silk, adsorption kinetics
