| Description |
Incorporating Hybrane H1500 as a nanostructured hyperbranched polyesteramide into polyethylene terephthalate (PET) enhances the dyeability of PET with C.I. Disperse Blue 56. The results show that the disperse dye display much greater substantivity toward the modified PET sheets compared to virgin PET one. DSC tests show that the crystallinity of modified PET sheets has slightly decreased. The main pur-pose of this work was to determine the dyeing mechanism of disperse dye on the modified PET using hy-perbranched polyesteramide by study the adsorption properties in the infinite dyebath at different tem-peratures. In fact, a few of the thermodynamic parameters of dyeing such as the equilibrium adsorption isotherm, standard affinity, enthalpy and entropy changes were studied. The bath containing virgin PET displays the highest negative values of the enthalpy change and entropy change, while the bath containing the modified PET with 2 wt% hyperbranched polyesteramide shows the lowest negative values of them.
