Abstract

In order to obtain tasic information for solvent dyeing, polyethylene terephthalate (PET) films was pretreated with water, tetrachloroethylene (TCE) and water/TCE emulsion for three hours at $140^{\circ}C$ for stabilizing the substrate. By film roll cyliderical method, Disperse Red 60, Disperse Yellow 42, and Disperse Blue 27 were diffused in the films and examined dyeing properties. The results are summarized as follows; 1) Diffusion coefficient increases in the order, waterTCE>water/TCE 2) A linear relationship between diffusion coefficient and shrinkage was Observed 3) The temperature dependence of the diffusion coefficient can't be expressed by WLF equation.
