Definitions

  • the invention aims to create an installation of this kind allowing the implementation of bleaching and dyeing processes which are less expensive and / or which have a shorter duration and / or which give a treated yarn of better quality.
  • the installation according to the invention makes it possible in particular to reintroduce the bath of the autoclave into the preparation tank where it can be reconditioned.
  • the installation makes it possible to carry out this reintroduction by means of steam without the bath being heated.
  • connection of the steam source with the second space opens into the upper part of this second space and the installation comprises a duct connecting the lower part of the second space to the upper part of the preparation tank.
  • the invention also relates to a method of treating wires on a coil which can be implemented by the installation determined above and according to which the coils of cold wire are impregnated with a treatment liquid in an autoclave, the liquid from the autoclave and the coils are steamed in the autoclave.
  • the impregnation is carried out by leaving an air cushion above the liquid in the autoclave and the liquid is removed from the autoclave by introducing steam above the air cushion, l evacuation being interrupted when the steam reaches the liquid discharge outlet.
  • the steam treatment is regulated for a predetermined duration counted from the moment when a determined temperature is reached inside a coil.
  • the known installation shown in FIG. 1 comprises an autoclave 1, an expansion tank 2 also used for adding liquid, a tank 3 used for the preparation of the bleaching solution, pumps 5 and 6, a heat exchanger 11 and various conduits and valves described below.
  • the autoclave shown in a less diagrammatic manner in FIG. 2, is equipped with a holder for coils 69. These coils determine inside the autoclave a first space 67 on the inside of the coils 69 and a second space 68 on the outside of the coils.
  • the first interior space 67 is essentially constituted by the central channels of the stacked coils.
  • the second external space 68 is constituted by all that surrounds the coils 69. As can be seen in FIG. 2, there is nowhere a direct communication between the internal space 67 and the external space 68. liquid can pass from the interior space 67 to the exterior space 68 or vice versa only through the coils 69.
  • a closed circuit is formed by the interior space 67, the conduits 7 and 8, the pump 5, the conduits 9 and 10, the exterior space 68 and the coils 69.
  • the pump 5 drives the liquid in the direction of the arrow 70, therefore in a direction such that through the coils 69 the liquid circulates from the interior space laughing 67 towards the outside space 68.
  • the heat exchanger 11 is interposed in the duct 9.
  • the autoclave 1 is connected to the general evacuation conduit 13 by the aforementioned conduit 10 and by the emptying conduit 14 which comprises the valve 15.
  • the suction part of the pump 5 is connected not only to the duct 9, but also to the duct 29 which comprises the valve 30 and which is supplied by the pump 6 from the expansion tank 2 through the ducts 16 and 71.
  • a conduit 23 communicates with the upper part of the exterior space 68 of the autoclave 1 and passes through the bottom of this autoclave 1 without communicating with the interior space 67.
  • This conduit 23 is connected by the conduit 24 to the conduit 25 which comprises the valve 26 and opens into the expansion tank 2.
  • the liquid in the upper part of the external space 68 can therefore overflow through the conduits 23, 24 and 25, if the valve 26 is open, in the expansion tank 2, from which the liquid is sucked by the pump 6 and discharged through line 29, if valve 30 is open, in the circuit formed by pump 5, lines 8 and 7, autoclave 1 and lines 10 and 9.
  • conduit 16 is also connected to the general evacuation conduit 13 by the conduit 17 which includes the valve 18.
  • the conduit 25 is also connected by the conduit 27, comprising the safety valve 28, to the general evacuation conduit 13.
  • the autoclave 1 can therefore also overflow towards the general evacuation conduit 13 through the conduits 23, 24 and 27.
  • the upper part of outdoor space 68 is also connected to the general evacuation conduit 13 by the connector 63 and by the conduit 35 which comprises the valve 36.
  • the preparation reservoir 3 is supplied with water through the conduit 37 comprising the valve 38.
  • This reservoir 3 is connected to the general discharge conduit 13 by the conduit 19 comprising the valve 20.
  • the conduit 31 connects the conduit 19 on the one hand to conduits 9 and 29 on the other hand. It comprises a valve 32 and on the side of the conduits 9 and 29 with respect to this valve a supply conduit 33 comprising a valve 34.
  • FIG. 3 presents a series of complementary elements which are described below.
  • a vacuum pump is connected by a conduit 39, comprising a valve 40, to the connector 63 provided at the top of the autoclave 1.
  • the same connector 63 is connected by a conduit 41 comprising a valve 42 to an air source compressed.
  • the autoclave is also provided with a level 48 regulator.
  • a source of steam supply feeds the conduit 43 which is connected by the conduit 44, comprising the valve 45, to the conduit 23 opening into the upper part of the external space 68 of the autoclave 1.
  • the conduit 46 comprising the valve 47, connects the conduit 43 supplied by the steam source to the conduit 7 opening into the interior space 67 of the autoclave 1.
  • Line 14 is connected between valve 15 and line 10 to a line 49 which opens into the upper part of the tank 3 used for the preparation of the bleaching solution.
  • the conduit 49 opens into the reservoir 3 at a point situated above the maximum level of the liquid in this reservoir.
  • the conduit 49 comprises a temperature measuring device 50.
  • This temperature measuring device 50 controls a valve 51 interposed in the conduit 49 and closes this valve when the measured temperature exceeds a predetermined value.
  • the temperature measuring device 50 is located between the valve 51 and the preparation tank 3. The valve 51 is therefore closed only when the predetermined temperature is already reached downstream of this valve in the direction of the tank 3.
  • Another temperature measuring device 66 measures the temperature inside a coil 69 and controls the activation of a timer when a predetermined temperature is reached, this timer closing the valve 45 and / or the valve. 47 after a predetermined period.
  • a valve 12 is interposed in the conduit 8 connecting the conduit 7 to the pump 5.
  • the valve 12 is normally open; all other valves are normally closed.
  • the conduit 64 comprising the valve 65, connects the conduit 8 between the conduit 7 and the valve 12 to the general evacuation conduit 13.
  • the conduit 52 serves, for example, to add a bleaching agent, for example hydrogen peroxide in the bath which is prepared and reconstituted in the reservoir 3; the flow rate of this agent can be adjusted by the metering pump 53 as a function of an automatic titration apparatus 72.
  • the conduit 54 serves, for example, to add an alkali to give or restore the appropriate pH to the bath. This alkali flow rate is adjusted by the metering pump 55 as a function of the pH measured by the pH meter 73.
  • the reservoir 3 is further provided with an agitator 56 and a level controller 57.
  • the installation according to FIG. 3 allows the implementation of certain new processes which require a shorter time for bleaching or for dyeing and / or are less expensive and / or give a better quality product.
  • a process which can be implemented with the installation according to FIG. 3 is a bleaching process also calling for steam treatment.
  • This process essentially includes an impregnation phase, a recovery phase combined with deaeration of the autoclave and a steam treatment phase, possibly followed by soaping and other finishing treatments.
  • the pump 5 causing circulation in the direction of arrow 70, the bleaching solution passes by the coils 69 from the interior space 67 to the exterior space 68.
  • the coils 69 are partially immersed in the bleaching solution or are not immersed at all.
  • the level of the bleaching solution in the autoclave is determined by the level regulator 48.
  • the valve 42 is opened to bring the pressure inside the autoclave 1 to about 2 bars.
  • the pump 5 is started to circulate through the conduits 10, 9, 8 and 7 in the direction of the arrow 70 so that the solution passes through the coils 69 from the interior space 67 in the direction of the external space 68.
  • the duration of the impregnation depends in both cases on the characteristics of the pump, but is generally of the order of 5 to 10 minutes.
  • the bleaching solution can be based on hydrogen peroxide or sodium chlorite.
  • the quantity of solution absorbed by the cotton is not determined by expression by compressed air or by suction under vacuum, therefore by operations according to the impregnation proper, but by an appropriate concentration of a suitable wetting agent in the impregnation bath.
  • This way of regulating the percentage of liquid absorption in cotton has the advantage, compared to compression by compressed air, that ration before steaming is made easier.
  • the cover of the autoclave 1 can be connected directly to the conduit 25.
  • the conduits 23 and 24 can be omitted in the embodiment according to FIG. 1 and the conduit 23 can be omitted in the embodiment according to FIG. 3.
  • the overflow of the autoclave 1 takes place via the conduit 24 ′, either towards the expansion tank 2 if the valve 26 is open, or towards the general evacuation conduit 13 if the valve 26 is closed.
  • the conduit 24 ′ therefore plays the role of the conduits 23 and 24 of the embodiments according to FIGS. 1 and 3.
  • the conduit 24 ′ also allows, in the embodiment according to FIG. 3, the introduction of steam into the upper part of the exterior space 68 if the valve 45 is open. Indeed, the steam can then pass through the conduits 43, 44, 24, 25 and 24 'in the upper part of this external space 68. All of this does not modify the functions described above of the known installation of the Fig 1 and the installation according to the invention of Figure 3.
