Claim:
Device for continuous treatment of yarns with process fluids characterized in that it comprises: means for introducing yarn threads which are fed for treatment by suction with a Venturi Nozzle ( 10 ), in which the process fluid is fed as driving fluid, entraining with it the yarn ( 1 ), either single or in a bundle, a distributing device, characterized as hollow tubes ( 13 , 113 ) which receive the bundle of yarn ( 1 ) and distribute it into a treatment reactor ( 5 ) forming a layer ( 34 , 134 ) with superimposed swirls, tank reactors ( 5 ), internally containing a saddle shaped guiding surface ( 35 , 135 ) on which the bundle of threads ( 1 ) deposited in a layer ( 34 , 134 ) 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 said bath, rising to an exit by a pulling of a discharge roll ( 40 , 140 ).
