Article's abstract:

This paper presents the influence of Hybrane H 1500 as a hyperbranched polymer on kinetic parameters of dyeing compounded fiber grade PET polyethylene terephthalate at boil temperature. C.I. Disperse Red 324 as a disperse dye was used for dyeing compounded fiber grade PET. The result was compared with corresponding properties of virgin PET. The dyeing rate constants and diffusion coefficients as the dyeing kinetic parameters were determined. The obtained results indicated that the rate of dyeing is closely related to the diffusion behavior of dye into the fiber. The dyeing rate of modified PET was faster than virgin PET. It was also found that the modified PET included 0.5 hyperbranched polymer as an additive, had higher diffusion coefficient as well as dyeing rate constant comparing to virgin PET. Small angle x-ray scattering SAXS was used to characterize compounded PET. SAXS measurement determined the size, shape and showed a homogeneous dispersion of hyperbranched polymer in compounded sample.
