Abstract

Dyeing properties of the easy dyeable polyester (EDP) and the polytrimethylene terephthalate (PTT) were investigated in terms of their thermodynamic and kinetic factors, such as standard affinity (-Δμ⁰), enthalpy change (ΔH⁰), entropy change (ΔS⁰), diffusion coefficient (D_T) and activation energy of the diffusion (E_D). The results were compared with corresponding properties of the PET (polyethylene terephthalate). The -Δμ⁰ of the EDP and the PTT showed a little higher value than that of the PET. PET displayed the highest negative values of the ΔH⁰ and the ΔS⁰, while PTT showed the lowest negative values of them. For all three polyester types, as the temperature increased, the D_T increased. PTT had the highest D_T at every temperature and PET showed the lowest values of the D_T. The E_D of the EDP and the PTT was lower than that of the PET.
