Definitions
- the present invention relates to the field of continuous processing of textile yarns, whether yarns made up of a plurality of filaments continuous or staple fibers of natural, synthetic or artificial.
- Document FR.2.282.492 also discloses a process continuous processing intended mainly to treat a ribbon fibrous using a false twist organ in order to untwist this ribbon after it has received an injection of a liquid, which can be a colored liquid.
- a liquid which can be a colored liquid.
- the fibrous ribbon is surrounded by a liquid sheath which, in the preferred application allows bonding of the ribbon fibers.
- the object of the present invention is to enable the treatment of all kinds of yarn, made up of fibers or filaments continuous, avoiding uncontrolled splashes of treatment bath and ensuring easy threading of the thread when the process is started.
- the bath contains a resin including pigments.
- the bath contains a resin including pigments.
- This system successively includes, on the course wire, an air suction nozzle, at least one spray nozzle a treatment bath, an air and excess discharge chamber treatment bath and a false air twist organ.
- the drying means consists of two drums heating, offset axes, on which drums the wire is wound and moves in the form of substantially contiguous turns.
- the wire 1 undergoes, on his journey in continuous movement, a succession of operations, know a suction operation thanks to an air suction nozzle 3, a spraying operation of a treatment bath using a spray part 4 comprising at least one nozzle, an operation exhaust air and excess treatment bath thanks to a evacuation chamber 5, a false twist operation thanks to a false air torsion member 6 and preferably a finishing operation in a finishing station 8 before being received at a finishing station reception 9.
- the finishing station 8 is a station drying with two heating drums 10,11 with offset axes, allowing the formation of substantially contiguous turns moving continuously on the peripheral surface of the two drums 10,11.
- the reception station 9 is a single winder.
- upstream of the suction nozzle 3 and in downstream of the false torsion member 6 can also be arranged respectively 2.7 deliverers each consisting of a pair of cylinders food. Thanks to these deliverers it is possible to vary the instantaneous wire displacement speeds; if the speed at first deliverer 2 is less than that of second deliverer 7, wire 1 is put under tension or even stretched; in the opposite case, a supercharging of the wire 1 in the assembly 12 comprising the suction, the spraying, evacuation and false twist. Likewise it is possible to vary the instantaneous speed of the wire between the second deliverer 7 and the receiving means 9.
- the suction nozzle 3 consists of a hollow part 13 comprising a central channel 14 for the passage of the wire 1, an annular chamber 15 supplied with compressed air by a line 16, and four conduits 17 connecting the annular chamber 15 to the channel central 14. These four conduits 17 are also distributed around the channel 14, radially to the axis DD of the said channel and inclined in the direction of movement of the wire according to the arrow F.
- the compressed air coming from the conduit 16 fills the annular chamber 15 and is projected by the conduits 17 towards the inside of the central channel 14, obliquely, pushing the wire 1 in the direction of the arrow F.
- the structure of the spraying part 4 is similar to that just described for nozzle 3 of spraying, with the hollow part 18, the central channel 19, the chamber annular 20, the supply line 21 and the four conduits 22.
- the supply line 21 is supplied not with compressed air but by a pressure treatment bath which is distributed in the room annular 20 and is projected into the central channel 19 through the conduit 22. This projection of a high pressure liquid through a small diameter corresponds to a spray of fine droplets which penetrate to the core in wire 1 passing through channel 19.
- the evacuation chamber 5 consists of a hollow part 23 comprising a central channel 24 for the passage of the wire 1 and laterally a large diameter discharge pipe 25 leading to a receptacle not shown, with filtering and possible recycling of the bath recovered.
- the false-torsion member 6 consists of a hollow part 26 with a central channel 27, an annular chamber 28 supplied by a compressed air supply line 29 and four conduits 30 connecting the annular chamber 28 and the central channel 27
- the central channel 27 is broken down, in the example illustrated in FIG. 2, into five successive portions.
- the first portion 27a the most upstream in the direction of movement of the wire according to the arrow F, is a converging frustoconical portion.
- the other three following portions 27 b , 27 c and 27 d are cylindrical portions of increasing diameter and the fifth portion 27 e is a divergent frustoconical portion.
- the four conduits 30 are arranged between the annular chamber 28 and the third portion 27 c of the central channel 27 so that the compressed air penetrates tangentially with respect to said channel, creating a vortex movement inside said third portion 27 c .
- the second portion 27b has a small diameter which is slightly greater than the diameter of the wire 1 to be treated. Under these conditions, the air that escapes from the conduits 30 is preferably driven downstream, that is to say towards the portions 27 c to 27 e , which gives the false torsion member 6 a component. suction, which further facilitates threading the wire at the start of the installation.
- the frusto-conical shape of the first portion 27 a is also designed to facilitate this threading.
- the small diameter of the second portion 27b also makes it possible to prevent the excess treatment bath coming from the central channel 4 from the evacuation chamber 5 from entering the false torsion member 6.
- the embodiment which has just been described with regard to the assembly 12 is not limitative of the invention.
- the number of conduits, their angle of inclination relative to the axis DD, their section, the pressure supply for each pipe depend on the amount of bath treatment to be deposited on the wire, the viscosity of the treatment bath, wire speed ...
- the device which has just been described has an important advantage, compared to this second version, namely that the air sent into the central channel 14 of the suction nozzle 3 in the direction of the arrow F prevents the rise, against the flow of the wire 1, of the treatment bath droplets projected into the central channel 19 of the room spray 4. In operation there is therefore no flow of treatment bath escaping through the inlet 14 a of the channel 14 of the suction nozzle 3.
- the section of the evacuation pipe 25 is greater than or at least equal to that of the inlet orifice 14 a of the suction nozzle 3.
- the section of the central channel 19 of the spraying part 4 must be equal to or greater than that of the central channel 14 of the suction nozzle 3.
- the three central channels 14,19,24 had the same diameter of 5mm and the discharge pipe 25 has a diameter of 8.5mm.
- the conduits 17, 22 had a diameter of the order of 0.5 to 0.8 mm.
- the pressure of the compressed air supplying the suction nozzle 3 and the false-twist member 6 was 3 and 6, respectively. 10 5 Pa (3 and 6 bars).
- the supply pressure of the treatment bath in the line 21 of the spraying part 4 was 4.10 5 Pa (4 bars). Under these conditions, with a treatment bath comprising a concentration of the order of 100 g / l of a pigmented resin, of the acrylic type, an acrylic yarn of 33 tex was obtained at speeds of several hundred meters per minute.
- a take-up rate of the order of 10 to 20% at the outlet of the assembly 12 the take-up rate being, in proportion with respect to the dry weight of the wire, the amount of treatment bath carried by it .
- the distribution of the pigmented resin in the cross section of the wire turns out to be perfectly homogeneous. We can give the following explanation to this.
- the droplets are projected onto the wire at very high speed and penetrate the heart of the wire; this penetration is further improved by the temporary torsion caused by the false torsion member 6, a torsion which rises on the wire at least at the level of the evacuation chamber 5.
- the wire 1 emerging from the assembly 12 is dried on the two heating drums 10,11 then coil.
- the two deliverers 2 and 7 make it possible to adjust the speeds snapshots of wire 1 during its upstream and downstream movement of the assembly 12 then between the assembly 12 and the winder 9. It is therefore thanks to this setting of instantaneous speeds, it is possible to supercharging of the wire 1 during its passage through the assembly 12.
- This possibility is particularly interesting for the treatment of threads textured multifilament, not heat-set, for example yarns polyester. This usually avoids all operations desirable if we want to obtain a particularly textured yarn in the end bulky and swelling.
- the implementation of the installation according to the invention provides results on this type of product better than a dye on hanks.
- the implementation of speeds different localized as above turns out particularly interesting when it comes to maintaining a foam effect on a given wire or elastic.
- the assembly constituted by the suction nozzle, the spraying part, the evacuation chamber and the false twist member is formed under a one-piece shape.
