Apparatus of continuously treating wide knitted fabric

Abstract

An endless net conveyor is suspended from a drive wheel which is mounted at an upper part of the apparatus, hanging into a treating bath, and a metal gauze member is extended along the outer periphery of the net conveyor thereby forming a U-shaped path between the net conveyor and the metal gauze member. One upper opening part of the U-shaped path constitutes an introduction side for insertion of the fabric to be treated, and the other upper opening part of the U-shaped path constitutes an exit side for the treated fabric, both upper openings serving to convey the fabric continuously therethrough during treatment. Injection pipes are provided in the bath on both exterior sides of the U-shaped path, namely on an inside side and on an outside side of the path, the injection ports of the pipes being alternatingly directed toward the path. A circulation pump disposed outside of the bath circulates the treatment liquid, the suction side of the circulation pump being connected in communication with the treating bath inwardly of the net conveyor. The blowing side of the circulation pump is connected to the upper part of the U-shaped path and to the injection pipes on both the inside side and the outside side of the path, respectively, via injection-flow control valves.
