摘要
为研究表面活性剂对靛蓝上染棉织物的染色效果的影响,分别采用分散剂NNO、匀染剂平平加O、渗透剂SRD,制备单体和复配溶液,测试其溶液的润湿能力和对烧碱、保险粉的兼容性。制备靛蓝染液并做空白试验,测试4种隐色体溶液的氧化还原电位。同时,对纯棉织物染色后的各项性能进行测试分析。结果表明:3种表面活性剂耐碱和耐保险粉性能良好,其中渗透剂SRD的渗透能力最好,并可迅速提升氧化还原电位,加快靛蓝染料还原;3种表面活性剂对靛蓝染料起到缓染作用,降低了初始上染百分率;分散剂NNO起到染色增深效果,平平加O和渗透剂SRD的使用效果相当,在皂煮前和皂煮后颜色最浅;使用平平加O的色纱白芯最明显,使用渗透剂SRD和空白试验的色纱白芯度次之;平平加O和渗透剂SRD可提高织物的耐摩擦色牢度;渗透剂SRD更有利于生产应用。
In order to research the effect of surfactants on indigo dyeing,monomer solution and compound solution were prepared separately by NNO,peregal O and penetrant SRD,the wetting ability of solution and compatibility with caustic soda and sodium hydrosulfite were tested.The indigo dye solution and the blank were prepared,the redox potential of four dyeing solution were tested.Meanwhile,the properties of cotton fabric after dyeing were tested and analyzed.The results show that,the three surfactants have good alkali resistance and insurance resistance,SRD has the best permeability,it can improve the redox potential rapidly and accelerate the reduction of indigo dye.The three surfactants slow down the speed of indigo dyeing and reduce the dye uptake of indigo in initial dyeing stage.NNO can deepen the color,peregal O and penetrant SRD have the same effect,and the color are lightest before and after soap cooking.The white core of color yarn with peregal O is the most obvious,followed by penetrant SRD and the blank test.Peregal O and penetrant SRD can improve the rubbing fastness of fabric.SRD is more conducive to production applications.
