摘　　要：采用氢氧化钠从姜黄中提取姜黄色素,讨论提取温度、时间、姜黄浓度及碱剂用量对提取效果的影响;将提取的姜黄天然染料对大豆纤维进行染色,讨论染色方法、染色温度、时间及盐用量对染色效果的影响,并优化了染色工艺。优化的姜黄色素提取工艺为:姜黄80 g/L,NaOH 30 g/L,90℃提取75 m in;优化的大豆纤维姜黄色素染色工艺为:采用同浴媒染法,染液选择未稀释姜黄提取原液,Zn2+媒染剂0.08 mol/L,媒染温度100℃,染色时间60 m in。大豆蛋白织物染色后,干摩擦牢度良好,湿摩擦牢度稍差,具有一定的抗菌性能。Curcumin is extracted from Curcuma with sodium hydroxide solution and used to soybean protein fiber dyeing.The influences of extraction temperature and time,dosage of Curcuma and sodium hydroxide on extraction results are discussed.The effect of dyeing process,dyeing temperature and time,and salt concentration on dyeing results are studied.The optimum extraction conditions are curcuma 80 g/L,NaOH 30 g/L,extracting at 90 ℃ for 75 min.The optimum dyeing conditions are meta-mordanting dyeing with stock curcumin extact and Zn2+ 0.08 mol/L at 100 ℃ for 60 min.The dyed soybean fabric features excellent dry rub fastness,and some antibacterial property.
