摘　　要：使用环境友好型的染色介质十甲基环五硅氧烷(D5)对棉织物进行轧染染色。探究碳酸钠质量浓度、固色时间和固色温度对活性染料固色率和棉织物匀染性的影响,确定C.I.活性红195在非水介质D5染色环境下的最优染色工艺。结果表明:当碳酸钠质量浓度为50 g/L,固色时间为6 min,固色温度为93℃时,棉织物能达到最佳染色效果;在此条件下,染色棉织物耐摩擦色牢度达到4级,耐日晒色牢度达到4级,均符合国家标准要求。对比常规水浴染色,该染色工艺能大幅度节约能源,缩短染色时间,达到清洁染整的目标。Pad dyeing of cotton fabric is carried out with an environmentally friendly dyeing medium,Decamethyl cyclopentasiloxane(D5).The effects of sodium carbonate concentration,fixation time and fixation temperature on the fixation rate and levelness of cotton fabric with reactive dyes are investigated,and the optimum dyeing process of C.I.Reactive Red 195 in D5 non-aqueous medium is determined.The results show that when the mass concentration of sodium carbonate is 50 g/L,the fixation time is 6 min,and the fixation temperature is 93℃,cotton fabric can achieve the best dyeing effect;Under these conditions,the color fastness to rubbing of dyed cotton fabric reaches level 4,and the color fastness to sunlight reaches level 4,both of which meet the requirements of national standards.Compared with conventional water bath dyeing,this process can greatly save energy,shorten dyeing time and achieve the goal of clean dyeing and finishing.
