涤纶纤维以D5为介质的分散染料染色研究

his experiment selected a new kind of environmental media (D5) instead of using water on the dyeing of PET, and the important factors affecting dyeing results were studied. It was found that a small amount of water in the D5 system can improve the dyeing properties, and the method of add water can also effect dyeing properties. The amount of water added in the D5 with heavy fabric and dye concentration has nothing to do only with the volume of the D5. When the D5 system in the dyeing conditions: pure disperse the concentration of 0.8%(o. w. f), the fabric weight 1g, bath ratio of 1:20, add water, 0.3mL, dyeing temperature of 130 ℃, holding time of 60min, can be obtained same effect with conventional high temperature and pressure dyeing in water, and without adding any dispersing agent, dyeing process eco-friendly.
