摘　　要：分别用乙酸和乙酸-乙酸钠缓冲液调节现用两只分散染料的染浴pH,对比其在染色前后染浴pH的变化,以及在不同pH下染料的上染情况。检测数据得出两只染料的上染pH范围,并讨论两只染料染色时使用乙酸或乙酸-乙酸钠缓冲液的区别。The two disperse dyes used to adjust pH with acetic acid and acetic acid-sodium acetate buffer respectively,and changes of the pH of dye bath before and after dyeing were compared,as well as the up dyeing of the dye at different pH.The pH range of two dyes was obtained from the test data,and the difference of using acetic acid or acetic acidsodium acetate buffer in dyeing with two dyes was also discussed.

关 键 词：分散染料 PH 染色 缓冲溶液
