EDDHA-Na在活性染料皂洗中对色牢度的影响研究

Study on Fastness Effect of EDDHA-Na in Soaping of Reactive Dyes

EDDHA-Na(乙二胺二邻苯基乙酸钠)是一种多功能金属离子控制剂,其对金属离子有较强的捕捉能力,具有极佳的吸附和分散作用。探讨其在活性染料皂洗工艺中对色牢度的影响。

EDDHA-Na （Ethy Diaminedhephen Acetic-Na） is a muhifunctional metal ion control agent containing amide group, the amide bond and an oxygen atom connected, high molecular weight, stable performance in aqueous solution with high temperature and strong acidity, have a stronger ability to capture metal ion complexes, adsorption of excellent and dispersion, can be firmly combined with unfixed reactive dyes, soaping agent is a good reactive dyes. This paper investigate its in reactive soaping process. So, EDDHA-Na is a good anti-staining soaping agent for reactive dyes. In this paper, we discussed its application in reactive soaping process.
