Patent ID: 7090702

Claim:
A system for continuous treatment of yarns with process fluids characterized in that it comprises: means for preparing and feeding ( 10 ) of a single thread or bundle ( 4 ) of various threads ( 1 ), means for introducing the yarn in the bundle ( 4 ) fed for treatment by suction with a Venturi nozzle ( 12 ), in which the process fluid is fed as driving fluid under pressure, entraining with it the bundle of yarn ( 4 ), distributing devices ( 13 ) which receive the bundle of yarn ( 4 ) and distribute it into a treatment reactor ( 11 ) forming a layer with superimposed swirls, one or more tank reactors ( 11 ) which receive the bundle of threads ( 4 ) together with the process fluid, internally containing a saddle-shaped guiding surface ( 79 ) on which the bundle of threads ( 4 ) deposited in a layer of swirls moves continuously first with a downward motion immersing it in a process fluid bath, and then with an upward motion with emersion from the bath, rising to an exit by the pulling of discharge rolls ( 20 ).
