Abstract
Abstract A method for liquid treatment of a fabric, in which the fabric to be treated in a rope form or web form is circulated in a predetermined direction within a treatment bath in a treatment tank, is disclosed. The subject method comprises the steps of providing outside of said treatment bath in said treatment tank, a treatment chamber consisting of a shower section provided with a fabric inlet, and a treatment section communicated with said shower section and having at least one constricted portion in the midway thereof, and surrounding said fabric so as to pass said fabric therethrough; providing a treatment conduit extended from said treatment chamber to within said treatment bath in said treatment tank; supplying a treatment liquid to within said chower section of said treatment chamber to seal said fabric inlet with said liquid during the circulating process of the fabric; then jetting said treatment liquid in the direction of travelling of the fabric within said treatment section to cause the treatment liquid to spout through the clearance between the fabric and said constricted portion when the fabric is passing through said constricted portion, and thereby to cause said fabric to carry out a shaking motion positively; and further leading said fabric from the outlet of said treatment chamber through said treatment conduit to within said treatment both while maintaining said fabric to be immersed in said treatment liquid. An apparatus for carrying out the above method is also disclosed.
