Development and Application of Polyester/Cotton Blended Fabric Dyes

Abstract

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,1HNMR,13CNMRand 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.
