This experiment selected a new kind of environmental media (D5) instead of using water on the dyeing of PET, this work provided a new method for non-aqueous dyeing. The effects of the water addition, temperature, dyeing time and reagents on adsorption amount of disperse dye were studied, one good dyeing process is, adding 0.5mL water and 0.3mL ethanol into 20mL D5 system, the temperature of dyeing was 130°C, the preservation time of dyeing was 60min.

The effect of atmospheric pressure dielectric barrier discharge plasma treatment on desizing polyvinyl alcohol (PVA) on polyester fabric was discussed as compared desizing with alkali through a combination of desizing rate, field scanning electron microscopy and strength test. The dyeing properties of polyester fabrics treated with atmospheric plasma have also been studied. The results show that plasma treatment can improve desizing rate, surface color depth and dye-uptake for polyester fabric.
