摘　　要：研究了C.I.活性蓝19及其对位异构体的上色性能及固色性能,并计算出它们的直接性S、竭染率E、固色率F、反应性R值,通过比较,分析了其结构与染色性能的关系。结果发现:C.I.活性蓝19反应活性较高,固色性能较好;而C.I.活性蓝19对位异构体对纤维的亲和力较大,上色性能较好。两只染料的最终固色率接近。The dyeing properties of C. I. Reactive Blue 19 and its corresponding p-isomer were investigated and the effect of the dye structure on its dyeing properties was discussed. The results showed that C. I. Reactive Blue 19 was more reactive than that of its corresponding p-isomer,on the other hand its corresponding p-isomer exhibited greater affinity to fiber and gave higher dye uptake. The final dye fixation of the two dyes was very close. In addition, the four dyeing parameters of these two dyes, which were S （Substantivity） , E （ Exhaustion）, R （ Reaction rate） and F （Fixation） ,were calculated according to the dyeing curves.
