The invention provides a method and apparatus of applying ultrasound energy in wet treatment of textiles, particularly in a dyeing process. By keeping the articles to be dyed within an optimal zone of the sonoreactor, the method achieves a high dyeing efficiency, making it possible to dye at a low temperature, with little or no use of chemical assistants while achieve a dyeing quality comparable with conventional dyeing method relying on high temperatures and/or use of chemical assistants. The apparatus suitable for practicing the method uses a conveyor belt having two layers of meshes between the articles to be dyed are sandwiched exerting no tension on the articles. The conveyor belt can be configured to travel within the optimal zone of the sonoreactor, whereby constraining the articles under dyeing within the optimal zone. With such a conveyor belt, small pieces of articles can be dyed just as easily as the large ones.
