酒石酸盐作活性染料促染剂的研究

用酒石酸钠和酒石酸钾钠作为活性黄KE-4R染棉布的促染剂，考察其染色的影响因素和促染效果，并与柠檬酸钠的促染效果进行比较。结果表明，用酒石酸钠作促染剂，其最佳的染色参数为：染色时间25min，固色时间是30min，固色温度是85℃，固色剂浓度4~10g/L。这3种盐在质量浓度为50 g/L即能达到较好的促染效果。要获得最佳的促染效果，酒石酸钠的质量浓度是210g/L，酒石酸钾钠的质量浓度为230 g/L，柠檬酸钠的质量浓度为270 g/L。酒石酸钾钠的促染效果略优于酒石酸钠，这二者又都优于柠檬酸钠。

Tartrate used as accelerants of reactive dyestuffs

Both sodium tartrate and potassium sodium tartrate were used as accelerants in dyeing cotton with C. I. Reactive Yellow 84. The influencing factors on dyeing were investigated for the salts. At the same time, accelerating effects of the salts were compared with those of sodium citrate. It was found that the optimal dyeing parameters were as follows: dyeing time 25 min, fixing time 30 min, fixing temperature 85 oC, and concentration of the fixing agent 4-10g/L when sodium tartrate was used as accelerant. Moreover, acceptable accelerating effect could be obtained when the concentrations of all the three salts were 50 g/L. For obtaining the optimal accelarating result, concentrations of sodium tartrate, potassium sodium tartrate, and sodium citrate were 210, 230, 270 g/L respectively. In respect of accelerating result, potassium sodium tartrate surpassed sodium tartrate a little. However, both of them were superior to sodium citrate.
