Apparatus for textile processing and method of manufacturing

An apparatus comprising:

• a first transducer adapted to transmit ultrasonic waves of a first wavelength into a first tank, the first tank configured to establish a substantially standing ultrasonic wave pattern of the ultrasonic waves inside the first tank;
• and a disposer adapted to dispose a textile into the first tank at a first distance from the first transducer, wherein the first distance is determined based the first wavelength and, wherein the first tank comprises a first wall and a second wall, the first transducer is coupled to the first wall and the second wall is configured to reflect the ultrasonic waves and the first wall and the second are separated from each other to establish the substantially standing wave pattern into the first tank resulting in multiple cavitation zones and wherein the apparatus is configured to operate on a sweep frequency of ultrasonic waves, the sweep frequency is a band of frequencies around a first frequency, wherein the first frequency corresponds to the first wavelength and the disposer is configured to dispose the textile at the first distance, the first distance is determined based on the first frequency.
