Ultrasonic assisted industrial wool scouring

The work has shown that modification of the traditional wool scouring line by introducing an ultrasonic device could be a viable alternative for wool scouring industry. A standard six bath wool scouring line was retrofitted with two ultrasonic panels working at 80 kHz in bath 2. Scouring was carried out in three modes: conventional mode without the transport rake, ultrasonic mode without the transport rake, and conventional mode with the transport rake. Ultrasonic scouring was found to improve removal of grease and ash from the wool fibres.
