摘　　要：研究了C.I活性红261及C.I活性红240固色温度对棉纤维染色固色率的影响,同时采用液相色谱对染色模拟过程各组分的变化进行了跟踪研究结果表明,C.I活性红261上染率比C.I活性红240高提高CI活性红261染料固色率的有效手段是提高固色温度C.I活性红240的固色率受温度影响较小。Two commercial reactive dyes, C.I. reactive 261and C.I. reactive 240 which contained a monochlorotriazinne group and a sulphuric acid ester of b-hydroethylsulphone group simultaneously, were used for the study on relationship between the dyeing profile and fixation properties. And the curve of concentration change of dyes during the reaction was obtained by the analysis with high performance liquid chromatography (HPLC). The uptake of C.I. reactive red 261 was higher than that of C.I. reactive red 240. The fixation of C.I. reactive red 261 was improved by raising temperature, but the temperature had little effect on the fixation of C.I. reactive red 240.
