Journal Textile Coloration and Finishing Year / Vol., Issue, Month 2016 / V.28,no.3,Sept Title Analysis of the Dye Absorption Behavior in Accordance with the Dye Structure in the Cold Pad Batch Dyeing of Cotton Knit Authors Seok Il Hong, Chang Woo Nam and Woosung Lee* Institution/Affiliations Korea Institute of Industrial Technology Pages/Total page pp.175 ~ 182 / 8 Language Korean Abstract Abstract To investigate dyeing behaviors in accordance with dye structure in cold pad batch dyeing of cotton knit, monochlorotriazine-vinylsulfone bifunctional dyes and monofluorotriazine- vinylsulfone bifunctional dyes were prepared. The spectral property and solubility of the dyes were tested and compared with the imported dyes. In addition, exhaustion behaviors of individual and mixed dye solutions were measured to examine the influence of dye structure on dyeing behavior in cold pad batch dyeing. The substantivity, fixation, migration index and half dyeing time were also calculated for further analysis of dyeing behavior of the prepared dyes. As a result, both dyes exhibited the superior solubilities and satisfactory light absorption properties. Also, monofluorotriazine-vinylsulfone bifunctional dyes showed moderate sensitivity to alkalinity and proper kinetic index values compared with the monochlorotriazine-vinylsulfone bifunctional dyes and the imported dyes. The results indicated monofluorotriazine-vinylsulfone bifunctional structure of the dye is suitable for cold pad batch dyeing.
