Study on the dyeing of PET fiber with disperse dyes in D5 media

摘要

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.
