摘要
Reactive disperse dye was synthesized using 2-[(4-Aminophenyl) sulfonyl] ethyl hydrogen sulfate as diazo component, and 2-hydroxy-1, 4-naphthoquinone for coupling component. The molecular structure of reactive disperse dye was confirmed by infrared spectrum, ultraviolet spectrum, 1 H NMR, 13C NMR and mass spectrographic analysis, molecular formula of the dye is C18H15N2O9S2. Through the contrast experiments, the study analyzes the dyeing performance of the polyester/cotton blended fabrics dyed with reactive dye and disperse dye(using traditional dyeing methods) and reactive disperse dye. The fabrics dyed with reactive disperse dye, its rubbing fastness was up to 4-5, washable color fastness was up to 4-5. Both of them are superior compared with the traditional dyeing methods.
