摘　　要：为了节约染料和减少染色废水向环境的排放,对活性染料的循环染色进行了研究。首先对染色残液中的水解活性染料通过中和法再生,然后利用再生活性染料和补加原染料方法对柞丝绸进行一浴两步法循环染色。采用傅利叶红外光谱对激活前后活性红X-3B染料的结构进行了表征,采用测色配色法对多次循环染色试样进行了测试。结果表明,激活后活性红X-3B染料分别在685 cm^(-1)和621 cm^(-1)处具有与原染料一样的氯原子活性基特征峰,激活前后染色试样的K/S值同色性较好,且具有良好的色光和皂洗色牢度,试样的摩擦色牢度和强力指标没有下降,染色残液可以实现24次连续染色。To save dyes and reduce the discharge of dyeing wastewater to our environment,the recycle dyeing method of reactive dye was studied in this paper.The hydrolyzed reactive red dye X-3B in the dyeing residual liquid was first activated with neutralization method,and then the regenerated reactive dye was used to dye tussah silk fabric with the method of one-bath two-step by adding the original dye.FT-IR spectra were used to characterize the structures of the dye before and after activation,and the method of color measurement and matching was used to test the dyed tussah samples.The results indicated that the activated reactive red X-3B dye showed the characteristic peaks of helium atom active group at 685 cm-1 and 621 cm-1 like the original dye.On the other hand,K/S values of the dyed tussah samples before and after activation had the good consistency,and color right and washing fastness were good.the values of rubbing fastness and strength index did not decline.The residual liquid can achieve continuous coloring for 24 times.
