Previously, we reported that polyester fabric could be dyed with vat dyes by the pad / dry / thermosol process at 210oC adding sodium hydrosulfite and sodium hydroxide. In this study, polyester cr?pe de chine (Toray, Sillook Sildew) was dyed with twenty vat dyes by the thermosol process in presence of the dye dissolving agents such as urea, PEG and glycerine. Color depth increased by adding urea in the padding solution, but the dye penetration in a fiber was only in surface area. Although color depth decreased by the soaping and subsequent five times home laundering, comparably medium dyeing color depth was obtained. On the other hand, color fastness to dry and wet rubbing decreased apparently especially for dry rubbing, whereas sublimation, chlorine, and light fastness were almost no problems. Therefore, it seems that polyester fabric could be dyed with vat dyes by means of thermosol process like a disperse dyeing of polyester fabric.
