  Abstract

The selection of disperse dye is one of the most important factors in supercritical fluid carbon dioxide dyeing. In particular, PET fiber, which is widely applied to supercritical fluid dyeing, has a hydrophobic property and a low affinity with other ionic dyes, so it is very important to prepare criteria for the selection of disperse dyes. In this study, the affinity between PET fibers and six dyes was predicted by three methods, and the reliability of the proposed prediction methods was verified through experimental analysis after the supercritical dyeing process. The three methods used to predict the affinity of dyes to PET fibers are IOB (inorganic organic balance), chemical potentials, and surface free energy. To verify the reliability of the proposed prediction method, affinity and dyeability were evaluated through experiments. As a result of the experiment, disperse red 167 among the dyes used showed the best affinity and dyeability with PET, and similar results were also obtained through prediction methods.
