In this paper, The influence of heat set and dyeing on the structure of PTT fiber was investigated by FT-IR, DSC, critical dissolution time. The influence of heat set on the dyeability of PTT fiber was discussed, too. Meanwhile, many experiments on the dyeing performance of PET fiber were carried out. The effect of different dyeing temperature on the uptake and visual color depth value and dyeing characteristics of different dyes with temperature increasing were discussed, and the influence of temperature on the dyeing depth were also evaluated when dyeing for PTT and PET fiber in the same dye bath condition. Especially the kinetics and thermodynamics of dyeing with disperse dyes were mainly studied.
