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).
In this research, we did the optical spectral study for using
ultrasound energy in dyeing wool fibers using acid dyes. That we
dyed wool fibers using both traditional dyeing and ultrasound
techniques by using three acid dyes from different firms.
The results of exhaustion percentage of the dye had been compared "the total moving dyes from a solution to fibers after dyeing".
The exhaustion rate of some dyes increased by a large proportion
but the effect on the fastness of the light, rubbing and washing was not great.
