B型活性染料用于小麦蛋白纤维针织物的染色
Dyeing of Wheat Protein Fiber Knitted Fabric by B Type Reactive Dyes
【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。
【Abstract】 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 dyeing 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 value is about 9, and dyeing temperature is 40 ℃, dyeing time is 40 minutes, fixation temperature is 65 ℃, and fixation time is 60 minutes.
