摘　　要：分别用甲酸、乙酸及乙酸-乙酸钠缓冲溶液调节毛用活性染料Intrafast Black CE-G的染浴pH值,对比了其在染色前后染浴pH值的变化,以及不同pH下染料的上染情况。结果表明:采用乙酸-乙酸钠缓冲溶液,控制染浴pH值在4.0条件下,上色率和固色率均在99%以上。The dye bath pH of wool reactive dye Intrafast Black CE-G was adjusted with formic acid,acetic acid and acetic acid-sodium acetate buffer solution,respectively.The changes of dye bath pH before and after dyeing and the dye uptake at different pH were compared.The results showed that when the pH of the dye bath was 4.O,the dye uptake and fixation rate were both above 99%.
