摘要:

针对当前电化学染色过程中染料还原率低、染色深度差问题,选择不同价态的铁盐溶液作为媒介与葡萄糖酸钠和Abal B配体形成协同络合体系,对靛蓝染料进行电化学还原。通过染液还原电位、染料还原率、亚铁离子转化率研究不同铁盐媒介的电化学还原能力。结合试验和极差分析探究还原液浓度、电压、通电时间对靛蓝间接电化学还原体系性能的影响,并对其染色工艺进行优化。试验得到的优化还原工艺为:靛蓝染料、FeSO4·7H2O、葡萄糖酸钠、Abal B、NaOH质量浓度分别为2.5、15、12、10.5、37.5 g/L,工作电压为10 V,时间为40 min。在此条件下,染料还原率达到89.95%,染色后棉织物染色深度值比传统方法提高4.5%,色光偏红,染色牢度与传统染色相当。

Abstract:

Aiming at the problems of low dye reduction rate and poor dyeing depth in the current electrochemical dyeing process, this paper reports on the use of iron salt solutions with different valence states as media to form a synergistic complexation system with sodium gluconate and Abal B ligand, to achieve electrochemical reduction of the indigo dye. By controlling dyeing solution reduction potential, dye reduction rate, ferrous ion conversion rate, the effects of different iron salt media on the reduction effect of indigo dyes were studied. The effects of dye concentration, voltage and time on the performance of indirect electrochemical reduction system of indigo dye were investigated. The results show that the optimum process conditions were the concentration of indigo 2.5 g/L, ferrous sulfate 15 g/L, sodium gluconate 12 g/L,Abal B 10.5 g/L, sodium hydroxide 37.5 g/L, working voltage 10 V, and electrification time 40 min. Under these conditions, the reduction rate reached 89.95%, the dyeing depth value of dyeing was improved by 4.5% compared with that of traditional process. The color fastness of the two processes was found similar.

Key words: indigo dye, electrochemical dyeing, iron salt solution, dyeing depth, ferrous ion conversion rate
