Study of effect of ultrasound weaves on dyeing polyester with disperse dyes

In this study we used ultrasonic technology as a means of enhancing dyeing process efficiency of polyester fibers with disperse dyes, which had frequency 42kHz and, we studied the behavior of dye when the polyester dyed with (US) and with traditional dyeing methods (without US).

A Study of the possibility of improving the fastness of washing and rubbing of cotton fabrics dyed with direct dye by using microwave energy

In this study, samples of cotton fabric were dyed using direct dye by the traditional method as well as using microwave energy at different energy levels. It was noted that the use of microwave energy increase the dye exhaustion at the used energylevels compared to the traditional method, as well as improving the fastness to washing and wet rubbing.
