摘　　要：采用搅打发泡的方法研究了大豆分离蛋白浓度、pH值、表面活性剂对大豆分离蛋白泡沫性能的影响;选取多个有利于泡沫性能的因素,以大豆蛋白泡沫作为染料载体,选用活性黄染料对纯棉织物进行了泡沫染色的探究,测试了染色织物的匀染性、拉伸性和色牢度。结果表明,在pH值为7,大豆分离蛋白质量分数2%,十二烷基硫酸钠(SDS)质量浓度1g/L,Tween-80质量浓度2g/L的条件下,泡沫性能最优。泡沫染色织物的匀染性、色牢度均优于常规水浴染色,织物强力提高。Foam of soy protein isolate（SPI）is produced by whipping method. The effects of soy protein isolate concentration, pH value and surfactant on foaming property of SPI are discussed. Using SPI foam as a dye carrier, cotton dyeing with reactive yellow is carried out. Levelness, strength and color fastness of the dyeings are tested. The results show that the optimum foa- ming conditions are pH value of 7, SPI mass fraction of 2%, sodium dodecyl sulfate（SDS） of 1 g/L and Tween-80 of 2 g/L. Compared with conventional aqueous dyeing, the cotton dyeings with SPI foam feature better levelness, higher color fastness and strength retention.
