Abstract

Device for the continuous treatment of yarns with process fluids comprising a Venturi nozzle fed with process fluid as driving fluid to feed the yarn to the treatment, a distributor for distributing the yarn in the treatment reactor according to a layer of superimposed swirls, a tank reactor, internally equipped with a saddle-shaped guiding surface on which the threads arranged in a layer first descend for immersion and then rise emerging from the process fluid.

Claims

1. 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).

2. Device for the continuous treatment of yarns with process fluids according to claim 1, characterized in that the tank reactor (5) is in the form of a J, characterized by a straight portion and a curved portion, further characterized by an outer jacket and an internal, inaccessible sheath (36), also J-shaped, the bundle descending in a layer (34) on the curved portion of the inaccessible sheath (36).

3. Device for the continuous treatment of yarns with process fluids according to claim 1, characterized in that the distributing devices, having two ends (13, 113) are connected by one end to the Venturi (10) by means of a cylindrical joint, said cylindrical joint having the capability to rotate perpendicular to the direction of the movement of the yarn (14, 114), said distributing device is further characterized by an eccentric terminal part of the tube (15, 115) the entire distributing device is capable of rotating with the cylindrical joint around the axis of the cylindrical joint (14, 114), said eccentric end thereby deposits the yarn in swirls in an interspace (30, 130) between the outer jacket and the internal inaccessible sheath(36), said distributor being further characterized by having a clockwise and anti-clockwise, alternating angular swing.

4. Device for the continuous treatment of yarns with process fluids according to claim 3, characterized in that the clockwise and anticlockwise, alternating angular swing is activated according to (α

) rotation angles ranging from 90°

to 180°

.

5. Device for the continuous treatment of yarns with process fluids according to claim 3, characterized in that the rotating cylindrical joint is activated by an electric motor (18, 118) piloted by frequency.

6. Device for the continuous treatment of yarns with process fluids according to claim 3, characterized in that the distributing devices (113) are connected to the Venturi (10) with a cylindrical joint (114), which ends with a terminal eccentric part of the tube (115), which in turn is connected to a circular rotating lid (111) coaxial with the cylindrical joint (114), supported by the jacket of the reactor (5) and which is moved in an alternating and controlled rotation by means of a motor (118).

7. Device for the continuous treatment of yarns with process fluids according to claim 6, characterized in that the activation of the rotating lid (111) is effected with the interposition of a geared transmission (119, 120).

8. Device for the continuous treatment of yarns with process fluids according to claim 6, characterized in that the alternating rotating motion of the rotating lid (111) derives from the continuous rotating motion of a motor with the interposition of a connection rod-handle system.
