摘　　要：探讨[bmim]Br(溴代1-丁基-3-甲基咪唑)预处理对苎麻织物染色性能的影响,实验得出较合适的处理工艺:浴比1∶30,处理时间1.5 h,处理温度100℃.对处理和未处理织物的上染速率及吸附等温线类型作了比较,结果表明:苎麻织物经过处理后,上染率及上染速率均有较大提高,吸附等温线类型发生了改变.This paper discusses the effects of 1-butyl-3-methylimidazolium bromine ionic liquid on dyeing behaviors of ramie fabric. The optimum condition of ionic liquid pretreatment of ramie fabric is hath ratio, 1： 30;reaction time, 1.5h;reaction temperature, 100℃. Moreover, speed of dye-uptake and style of adsorption isotherm were compared with that of the untreated. Results show that pretreatment with ionic liquid is found to increase the rate and speed of dye-uptake significantly, meanwhile style of adsorption isotherm has changed a little.
