A study on the usability of ultrasound in scouring of raw wool

Ultrasound-assisted mercerizing process of cotton fabric: A numerical model based on response surface methodology (RSM)

“…High temperatures in an ultrasound bath exert two contradictory effects: decreasing the cavitation phenomena and lowering the alkalinity of the solution. Bahtiyari and Duran [2] reported limited effects of ultrasound at high temperatures due to the lowering of intensity of bubble collapse and cavitation phenomenon. However, at higher temperatures, the effect of mass transfer acceleration leads to obtain improved results.…”

“…Ultrasonic energy shows a high potency to improve a number of chemical processes, especially in aqueous systems such as ultrasonic bath and textile wet treatments like ultrasonic-assisted cleaning process [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16]. The phenomena of formation and subsequent collapse of bubbles (cavitation) can be regarded as the main factor for rate acceleration in chemical reactions (sonochemistry) and efficiency improvement through cleaning [15,17].…”

“…For many years, the application of ultrasound has been investigated in textile wet processing [2,[5][6][7][9][10][11][12][13][14][18][19][20][21][22][23]. Studying the effect of ultrasonic waves in the scouring of raw wool fibers, Bahtiyari and Duran [2] reported that the use of ultrasonic waves represents an energy efficient procedure and leads to improvement in the cleaning.…”

“…Studying the effect of ultrasonic waves in the scouring of raw wool fibers, Bahtiyari and Duran [2] reported that the use of ultrasonic waves represents an energy efficient procedure and leads to improvement in the cleaning. Khajavi and Azari [5] applied the same process for improving the wet chlorination process of wool.…”

Development of a two-step technology of scouring wool by the method of high-energy discrete treatment

“…The scientists [11] developed a technology of ultrasonic scouring of wool, which makes it possible to conduct treatment under the following technological parameters: concentration of SAS -1 g/l, the temperature of treatment -75 °C, duration of treatment -25 s. As a result of washing, the necessary level of removal of the natural contamination from wool is achieved.…”
