Definitions

  • the present invention relates to a method for preparing and readjusting a textile product treatment bath, in particular a dye bath circulating in a closed circuit in a main treatment circuit in which a treatment machine is mounted, in particular a dyeing machine.
  • the preparation of textile materials requires the implementation of various treatments, among which we can note the degreasing, desizing, scouring, bleaching, dyeing, rinsing, soaping, softening, various finishes, drying, relaxation ...
  • the treatment bath circulates in a closed main treatment circuit which may comprise, in addition to the treatment machine, means in particular a pump for circulating the bath and additional members such as for example a heat exchanger.
  • the object of the present invention is to remedy these drawbacks by proposing a method for preparing and readjusting a textile product treatment bath, in particular a dyeing bath of the aforementioned type which makes it possible to guarantee in all cases the obtaining of a homogeneous solution having the desired volume.
  • This process is characterized in that a mother solution concentrated in active product is prepared in a preparation or repacking tank and a controlled distribution of this mother solution is carried out in a redilution tank in which the treatment bath is circulated in particular the dye bath, the redilution tank being mounted in an additional circuit connected as a branch to the main treatment circuit and in which the treatment bath is circulated, in particular the dye bath in a direction opposite to its direction of circulation in the main processing circuit.
  • This process is particularly easy to carry out, and allows a homogeneous treatment bath to be obtained, and this faster than by conventional processes, since the homogenization is already prepared before introduction into the machine.
  • this process makes it possible to improve to a large extent the homogenization of the bath, given its continuous mixing with the flow coming from the main treatment circuit.
  • the invention also relates to an installation allowing the implementation of the above-mentioned method.
  • Such an installation comprises a closed main treatment circuit comprising a machine for treating textile products, in particular a dyeing machine, a circulation pump controlling the circulation in a first direction of a treatment bath, in particular a dyeing bath, as well an auxiliary circuit connected as a branch to the main treatment circuit.
  • the annex circuit comprises, on the one hand a redilution tank provided with organs for supplying a mother solution concentrated in active products previously prepared in a preparation tank or repacker, on the other hand control members making it possible to circulate the treatment bath, in particular the dye bath in a second direction opposite to the first, and, where appropriate, a temperature exchanger.
  • the annex circuit in bypass on the main treatment circuit on either side of the circulation pump.
  • control members consist of a redilution pump capable of transferring the treatment bath coming from the redilution tank into the main treatment circuit upstream of the circulation pump.
  • This configuration makes it possible to obtain a vigorous stirring of the bath coming from the redilution tank and from the bath leaving through the outlet orifice of the treatment machine directly upstream of the circulation pump.
  • control members are constituted by an injector using the pressure in the main circuit downstream of the circulation pump to transfer the bath coming from the redilution tank in this same main circuit upstream of the circulation pump.
  • This configuration makes it possible to obtain a more efficient homogenization than that obtained in accordance with the first variant, since the bath leaving the redilution tank is stirred, with the bath circulating in the main circuit, a first time at the level of the injector, then a second time directly upstream of the circulation pump.
  • the invention also allows automatic distribution over time of the mother solution as a function of the exhaustion of the bath in the treatment machine and of the desired results.
  • the repacker is equipped with a programmed valve allowing a regulated distribution of the mother solution in the redilution tank, as well as preferably, of an analog level cooperating with this valve programmed to dispense the mother solution by fraction of height according to a predetermined distribution curve, in particular on the product flow.
  • FIGS. 1 and 2 are schematic representations of two variants of the invention.
  • the strip of textile material A is brought into contact with a dye bath which is projected dynamically along the arrow ( a ) at the level of an introduction orifice 3 located at the top of the machine and falls to the bottom of it before being taken up at a discharge orifice 4.
  • the dye bath recovered at the discharge orifice is brought back in a closed circuit to the introduction orifice 3 according to the arrows b, by a main treatment circuit 5 comprising, in addition to the dyeing machine 1, a temperature exchanger 6 as well as a pump 7 allowing the circulation of the dye bath (arrows b).
  • an annex circuit 9 is provided, connected in branch to the main circuit 5 on either side of the pump 7 in which control members which will be described in more detail in the remainder of this description. , circulate the dye bath in a direction c opposite to the direction b of circulation in the main circuit 5.
  • This annex circuit 9 comprises a redilution tank 10 provided with an inlet orifice 11 of the dye bath as well as an outlet orifice 12 thereof.
  • the redilution tank 10 cooperates by elsewhere with a programmed valve 13 making it possible to introduce into the bath according to the arrow ( d ) a regulated quantity of a concentrated mother solution of dye previously prepared in a preparation tank 8 commonly called reponc wish.
  • This tank 8 also comprises an analog level 14 making it possible to control the level of the mother solution and to distribute it in the redilution tank 10 by fraction of height as a function of a determined distribution curve.
  • the circulation control members along the arrow c of the dye bath in the annex circuit 9 are simply constituted by a redilution pump 15.
  • control members consist of an injector 17 which uses the pressure of the fluid in the main circuit 5 downstream from the circulation pump 7 which is introduced at this level according to arrow f.
  • This configuration has, compared to the previous one, the advantage of allowing additional mixing of the various fluid streams at the level of the injector 17 from which it results in homogenization which is further improved.
