Abstract

In this investigation, DYEING KINETIC of MODIFIED PP FIBERS produced as polypropylene polybuthylene terephthalate (PP/PBT) polyblend fibers was studied. The modified fibers were dyed with selected DISPERSE DYE (C.I. Disperse Blue 56) at different times and temperatures. The experimental data was adjusted to well-known DYEING KINETIC equations, i.e. Vickerstaff, Patterson, McGregor and Cegarra-Puente to determine the rate constant of dyeing and diffusion coefficient at different temperatures. The results showed, exhaustion, constants rate of dyeing and diffusion coefficients, were increased with increasing the time and temperature of dyeing process. A significant enhancement in dye absorption was observed for dyeing in 120oC compare with other temperatures. So that, the time of dyeing saturation was reached two times faster in this DYEING TEMPERATURE compare to the other temperatures. The best adjustments with applied DYEING KINETIC equations were occurred with the Vickerstaff and Cegarra-Puente kinetic equations.However, the Vickerstaff equation was determined as the best model with regard to their highest average regression coefficients and suitable trend of DYEING KINETIC constants in the range of the DYEING TEMPERATUREs. Diffusion coefficient value was increased significantly (9 times) by increasing the DYEING TEMPERATURE. Furthermore, the highest variation of diffusion coefficient enhancement belongs to temperature variation from 100oC to 120oC. Also, trend of the diffusion coefficients showed a good conformity with the exhaustions trend in the different temperatures.
