摘要: 研究了双己基二甲基溴化铵(DDAB)作促染剂时,对三支活性染料在丝绸上上染的促染作用效果和促染动力学。研究结果表明:DDAB对活性染料在丝绸上的上染具有高效的促染作用。活性红B-3BF、活性黄B-4RFN、活性深蓝B-2GLN三支染料的平衡上染率分别达到98.7%、98.4%和97.3%。DDAB浓度分别为2.24g/L、2.72g/L和3.60g/L时,三支活性染料的上染率就已基本达到最高。固色率分别为98.2%、97.4%和96.3%。三种活性染料上染丝绸的吸附动力学数据均符合准二级速率方程。活性红B-3BF、活性黄B-4RFN、活性深蓝B-2GLN的表观活化能分别为18.23、14.83、15.75 kJ/mol。

Abstract: This paper studied the dyeing effect of di-hexyl dimethyl ammonium bromide (DDAB) as the dyeing accelerating on dyeing silk with three reactive dyes and the adsorption kinetics of dyeing. The results showed that DDAB had an efficient stimulative role in dyeing silk with reactive dyes. The balanced dye uptake of reactive red B-3BF, reactive yellow B-4RFN and reactive dark blue B-2GLN was 98.7%, 98.4% and 97.3%, respectively. And accordingly the fixation of three reactive dyes was 98.2%, 97.4% and 96.3%, respectively. The exhaustion of three reactive dyes reached the highest basicly, when the concentration of DDAB was 2.24g/L, 2.72g/L and 3.60g/L, respectively. The kinetics of three reactive dyes on silk with DDAB as accelerant was found to fit the pseudo second-order sorption kinetics equation well. Meanwhile the activation energy of reactive red B-3BF, reactive yellow B-4RFN and reactive dark blue B-2GLN dyeing on silk with DDAB as accelerant was 18.23, 14.83 and 15.75 kJ/mol, respectively.

Key words: dihexyl dimethyl ammonium bromide , reactive dye , silk, dyeing , kinetics , activation energy
