摘　　要：使用自行合成的7支偶氮-均三嗪型活性分散染料制备印花色浆,并将其用于棉织物的印花,测试了印花棉织物的色深值、固色率、色牢度、热迁移性和断裂强力等性能。结果表明:印花棉织物具有良好的得色率、鲜艳性和匀染效果,同时具有良好的耐有机溶剂萃取性能。印花棉织物固色率达到67%~84%,染料迁移率仅有2.4%~3.8%,耐皂洗、耐摩擦和耐升华色牢度可达4级以上,显现出优异的颜色坚牢性。Seven self-synthesized azo-triazine type reactive disperse dyes are used to prepare the pastes for cotton printing.The properties of the printed cotton fabrics,such as color depth,fixation value,color fastness,thermal migration and tensile strength,are tested.The results show that the printed cotton fabrics exhibit good color yield,brightness,levelness,as well as good resistance to organic solvent extraction.The fixation values of the printed cotton fabrics reach 67%-84%,with dye migration values ranging from only 2.4%to 3.8%.Be-sides,the color fastnesses to soaping,rubbing,and sublimation are above Grade 4,demonstrating excellent col-or firmness properties.
