摘要
将柠檬酸钠、甲酸钠、EDTA二钠盐作为促染剂用于棉织物活性染料染色,探讨了对固色率的影响,然后分别与元明粉复配,探讨最佳复配用量,并进行染色性能测试。结果表明,用柠檬酸钠、甲酸钠代替元明粉作促染剂时,促染效果较好,而EDTA促染效果较差;柠檬酸钠与元明粉复配最佳合计用量为32g/L,固色率为93.17%,盐用量降低36.00%;甲酸钠与元明粉复配最佳用量合计为24 g/L,固色率为89.56%,盐用量降低52.00%,但色差较柠檬酸钠与元明粉复配时大;将柠檬酸钠、甲酸钠与元明粉复配,复配最佳用量合计为31 g/L,固色率为91.35%,盐用量降低38.00%,耐皂洗色牢度整体有所提高,复配体系色差较小,促染效果较好。
With sodium citrate, sodium formate and EDTA disodium salt as accelerating agent,cotton fabric was dyed by reactive dyes, and the effects on fixation were discussed. And then sodium citrate, sodium formate and EDTA disodium salt was respectively compounded with sodium sulfate, and the optimal compounded dosage was discussed, and the dyeing property was tested.The results shows that accelerating effect is good when sodium citrate and sodium formate replaces sodium sulfate as accelerating agent, but accelerating effect of EDTA disodium salt is poor; the optimal dosage of sodium citrate and sodium sulfate compounded system is 32 g/L, the fixation rate is 93.17%, and salt consumption declines by 36.00%; the optimal dosage of sodium formate and sodium sulfate com-pounded system is 24 g/L, the fixation rate is 89.56%, and salt consumption declines by 52.00%, but color differ-ence is bigger when compared with sodium citrate and sodium sulfate compounded system; the optimal dosage of sodium citrate, sodium formate and sodium sulfate compounded system is 31 g/L ,the fixation rate is 91.35%, and salt consumption declines by 38.00%, and soaping fastness increases, color difference of compounded system is small, accelerating effect is good.
