Influence of ultrasonic on the dying properties of cotton fabric by using turmeric as dye

摘要

In the process of using dye turmeric, the behavior of conventional dyeing and ultrasonic dyeing were compared. The processing of conventional dyeing and ultrasonic dyeing, such as dyeing time, dyeing temperature, pH value, and the amount of salt on the effect of K/S value, were investigated. The results show that the dye-uptake was greatly improved by using ultrasound. Meanwhile, the ultrasound dyeing was demonstrated more dominant in energy saving.
