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 the continuous treatment of yarns with process fluids characterized in that it comprises:

means for introducing the yarn 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,

distributing devices (13, 113) which receive the bundle of yarn (1) and distribute it into the treatment reactor (5) forming a layer (34, 134) with superimposed swirls,

a 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 the process fluid bath, and then with an upward motion with emersion from the bath, rising to the exit by the pulling of the discharge rolls (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, containing inside an inaccessible sheath (36), also J-shaped, the bundle descending in a layer (34) on the concave part 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 (13, 113) are connected to the end part of the Venturi (10) by means of a cylindrical joint (14, 114) which ends with an eccentric terminal part of the tube (15, 115) capable of rotating around the axis of the cylindrical joint (14, 114), depositing the yarn with swirls in the interspace (30, 130) between the jacket of the reactor (5) and its surface (36, 136), said distributor being equipped with activation with a clockwise and anticlockwise, 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 activating device with an alternating swing of the distributor (13, 113) is an electric motor (18, 118) piloted in 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 end of 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 connecting rod-handle system.
