Notes:
The apparent diffusion coefficients of a disperse dye in the multiple layers of nylon fabric at 45-75°C are determined as the dyeing model of the textile assembly. The modified pore model is introduced to explain the diffusion behavior in the multiple fabric. The Arrhenius plot of the diffusion coefficient of dye in the spaces or pores of nylon fabric gave a straight line and the activation energy of diffusion was about 9.4 kcal/mol. The temperature dependence of the dye diffusivity in polymer matrix was quantitatively described by a WLF-type relation, \documentclass{article}\pagestyle{empty}\begin{document}$$\log a_T = - \frac{{3.55(T - T_s )}}{{26.8 + T - T_s }} $$\end{document} where aT is a shift factor of diffusion and Ts is the reference temperature.
