Abstract
In order to explore the mechanism and effect of new environmental friendly carrier on kinetics of polyester fiber dyeing, the influence of new environmental friendly carrier on typical DSC curves of polyes-ter fiber, disperse dye solubility, dyeing rate curves and isothermal adsorption curve were investigated. The re-sults showed that the carrier had plasticizing effect for polyester fibers and solubilization effect for disperse dye, which could effectively increase the solubility of disperse dyes and improve the dyeing rate constant, shorten the half dyeing time, increase the diffusion coefficient, saturated adsorption amount and distribution coefficient. However, it would not change the adsorption isotherm type of polyester fibers.关键词
