摘　　要：从分散染料选择、染色温度、染浴pH值、染色时间、升温速率、染料提升力以及染色牢度等方面研究了新型聚酯纤维PTT的染色工艺.结果表明PTT纤维的最佳染色温度为100～110℃,分散红60的升温速率为0.8℃/min.汽巴绥脱黑EL-FGL在6%(owf)时达到饱和值,分散红60在2%(owf)时达到饱和值,在pH 5～9染浴中染色,不需调节pH值,同时其摩擦牢度、水洗牢度可以达到4～5级.The dyeing process of PTT, a new polyester fiber, was researched in the fields such as dye selection, dyeing temp., pH value of the dyeing bath, dyeing time, temp. raising speed, dye build-up and dye fastness. The results showed that the best dyeing temp, for PTT fibers was 100-110 ℃, and disperse red C.I.60 temp. raising speed 0.8 ℃/min. C.B. black EL FGL reached the saturation at 6%（ewf）, and disperse red C.I.60 at 2%（owf）. The PTT fibers could be dyed in pH 5-9 baths without adjusting the pH values to give rubbing fastness and water-washing fastness 4-5.
