摘　　要：选用活性红B-2BF、活性黄B-4RFN、活性深蓝B-2GLN三原色染料对小麦蛋白纤维针织物进行染色,测试并分析了固色温度、元明粉用量、固色剂种类、pH值等因素对染色后织物皂洗牢度以及固色率的影响。结果表明,B型活性染料在小麦蛋白纤维针织物上的最佳染色工艺为:元明粉用量40 g/L,固色剂为碳酸钠,染浴pH值为9左右,染色温度40℃,染色时间为40 min,固色温度65℃,固色时间为60 min。Wheat protein fiber knitted fabric was dyed by the trichromatic dyes of reactive Red B-2BF, reactive Yellow B-4RFN and reactive dark blue B-2GLN, and the effects of fixation temperature, the dosage of anhydrous sodium sulphate, the species of fixing agent and pH value on soaping fastness and fixation rate of fabric after dye-ing were tested and compared.The results show that the optimal process of wheat protein fiber knitted fabric by B reactive dyes is that the dosage of anhydrous sodium sulphate is 40 g/L, fixing agent is sodium carbonate, pH val-ue is about 9, and dyeing temperature is 40 ℃, dyeing time is 40 minutes, fixation temperature is 65 ℃, and fixation time is 60 minutes.
