摘　　要：本文研发了一种新型的改性分散染料并对其染色性能进行研究。将β-乙烯砜硫酸酯活性基团引入到分散染料分子中,合成新的反应型分散染料,β-乙烯砜硫酸酯活性基团与羊毛形成共价键从而上染纤维,分散染料则上染涤纶。这种改性分散染料在pH值7,100℃时具有最高上染百分率。研究发现,含有双β-乙烯砜硫酸酯活性基团的改性分散染料的染色性能优于含单个活性基团的改性分散染料。改性分散染料的摩擦、皂洗和汗渍牢度较好。A kind of new reactive disperse dye and its dyeing properties were researched. The bis-sulphatoethylsolphone reactive groups were introduced into the disperse dye and formed a new reactive disperse dye. The bis-sulphatoethylsolphone reactive groups could form covalent bond with wool and disperse dyes could be taken up to polyester. Maximum exhaustion values were observed at pH value 7 and 100℃. The dyes containing bis-sulphatoethylsolphone reactive groups had better dyeing properties compared with mono-sulphatoethylsulphone reactive group dyes. All dyed fabrics had good rub fastness, soaping fastness and perspiration fastness.
