Ultrasound as a cleaning container, disperse dyes, powerful means of influencing chemical reactions have been used for many years. However, it has been recently discovered that ultrasound can be used to increase the reaction rate, reduce scouring time and dyeing time, and increase the whiteness of the fabric. Ultrasound can also improve a variety of textile processing techniques, as a widely used ultrasonic technology, has the ability to affect a variety of wet processing. Ultrasonic can change the desizing, scouring, bleaching, dyeing, finishing and washing process. Its use in wet processing can reduce processing time, reduce chemical consumption and energy consumption, and improve product quality.


Ultrasound is a type of sound wave whose frequency exceeds 17 kHz above the human hearing range. Ultrasound is like electromagnetic waves, refracted, focused and reflected. However, unlike electromagnetic waves, electromagnetic waves can propagate freely in a vacuum, while the propagation of ultrasound depends on elastic media. When it propagates, the particles in the elastic medium oscillate and transmit the energy through the medium according to the propagation direction of the ultrasonic wave. The waves can be divided into longitudinal waves and transverse waves. 


In solids, both can be transmitted, while in gas and liquid, only longitudinal waves can be transmitted. Since the dyeing and finishing processes are mostly wet processing, the study of the longitudinal waves of ultrasonic waves is of particular importance. Can make the fiber surface dye liquid dynamic boundary layer thinning, play a strong role in stirring, accelerated fiber surface adsorption of dyes. At the same time, this effect will enhance the dye-through and leveling effects. Although there are many advantages to using ultrasonic dyeing, there are many problems to be solved for industrial production. 


Such as processing and ultrasonic equipment costs, noise, ultrasonic directionality and other issues. However, we should also see the positive aspects of ultrasound. In the recent period, the application of ultrasonic waves to retreat, boil, bleach and dye in the dyeing and finishing process has made substantial progress. At present, ultrasound technology has also been gradually introduced into the treatment Printing and Dyeing wastewater come. This shows that efficient ultrasound can not only accelerate the fabric wet processing speed, improve the quality of the fabric, but also save energy and optimize the environment. The many advantages of ultrasound determine its great potential, and urgently need to actively develop and utilize scientific workers.
