Abstract
A high-pressure fluid processing device is provided, which is improved for application of impinging fluid jets to process an object, such as a woven fabric, to increase uniformity of application and processing of the object. Particularly, the present invention is useful for processing woven fabrics having small thicknesses and lower densities by compensation for overlapping regions that occur during high-pressure fluid processing. The high-pressure fluid processing device includes a header means that is translationally rotationally driven from a frame so as to move a plurality of nozzles thereon in circles to impinged the object conveyed thereunder with high-pressure fluid jets. Moreover, the device includes masking members that are positioned between the nozzles and the object to be processed so as to block at least some of the jet flow of fluid to increase uniformity of processing and to avoid unwanted bunching or shifting of fibers in a processed fabric.
