Definitions
- the present invention relates to textile finishing by passing a given material through a treatment bath, said material winding on itself after its passage, said passage being carried out alternately in one direction then in the other by successive winding and unwinding. More particularly, the present invention relates to an improved finishing process of this type as well as an apparatus intended for the implementation of said method, in particular an apparatus known under the name jigger.
- a jigger In a jigger, all types of fabric piece treatments can be carried out, including bleaching, dyeing, skinning, that is to say soaping the fabric after dyeing with reactive dye.
- the operating principle of the jigger is to unroll a piece of fabric wound on itself, in the form of a first roll, to make it move through a heated treatment bath, then to wind it again on itself as a second roll. Once the first roll is finished, the direction of movement is reversed so that the first roll is reconstituted at the expense of the second, the tissue continuing to pass into the treatment bath.
- the jigger has a number of control elements for reversing the direction of rotation of the rollers, stopping operation after a predetermined number of passes, regulating the speed of the rollers and the tension of the tissue.
- the jigger ranks among machines with a short bath ratio, the weight of treated materials compared to the volume of impregnation bath being low from 1 to 2. Its advantage lies therefore mainly in saving water and energy
- EP.A.O.O63.2O3 therefore requires the implementation of additional means, which moreover is hardly possible on existing equipment, and can cause condensation phenomena.
- the use of the jigger is not optimal in terms of treatment kinetics: according to their findings, this is due to a drop in the temperature of the treatment bath carried away by the textile during its entrainment and winding, decrease temperature caused by the passage from the bath at a given temperature in the air at a lower temperature.
- the aim which the applicants have set themselves is to propose an improved process which improves the kinetics of treatment, in an apparatus textile finishing of the jigger type.
- this object is perfectly achieved by the method of the invention.
- this is a textile finishing process in which the textile material passes through a heated treatment bath and is wound alternately in one direction and in the other with the application of electromagnetic waves on said textile material during its winding and / or its unwinding.
- the power of the electromagnetic waves is determined, as a function of the optimal temperature of the reaction implemented, so as to maintain substantially equal to or greater than this optimal temperature the temperature of the assembly constituted by the rolled up textile material and the bath with which it is impregnated.
- the applicants have in fact been able to verify that the action of electromagnetic waves on the textile material, impregnated with the hot treatment bath, makes it possible to obtain and maintain the optimum temperature for the reaction implemented within the winding, optimal temperature which promotes the physico-chemical reaction which is carried out during said treatment. They were able to note that this optimization of the temperature within the winding reduced, even eliminated the heterogeneities which appeared until then, without the action of electromagnetic waves. Much more they were able to verify that the method according to the invention had other advantages.
- the first advantage consists in a reduction in the treatment time which is necessary to obtain a determined effect, for example to obtain the same degree of white during a bleaching or even the same final shade during a dyeing.
- the second advantage consists in the possibility of an improvement in the effect obtained, for example a higher degree of white during bleaching, a more intense final shade during dyeing, a greater elimination of dyes during soaping.
- Other advantages follow from the previous ones, namely the possibility of reducing the concentrations of dye baths for a given final shade, a increased productivity
- the optimal temperature of the reaction implemented corresponds substantially to the temperature of the treatment bath as recommended by the producers of chemical reagents.
- the power of the electromagnetic waves must be such that the action generated on the textile material consists of maintain the temperature of the assembly constituted by the rolled up piece of fabric and the bath with which it is impregnated substantially equal to or greater than said optimum temperature
- the power of the electromagnetic waves is of course proportional to the quantity of materials treated, that is to say the textile material itself, to the bath with which it is impregnated and also to the speed of travel of this material.
- an appropriate electromagnetic (P) wave power could meet the following formula
- P (5.434 m ⁇ T) t " 'in which P is the power in kW, m the mass of the part in kg, ⁇ T the temperature difference in ° C to compensate (generally of the order of 15 ° C) between the desired temperature, equal to or higher than the optimal temperature and the actual temperature of the material on the winding, without application of electromagnetic waves and t the average time in seconds of winding in one pass
- the application of electromagnetic waves is carried out simultaneously on the two rollers, that is to say on the textile material during its winding and its unwinding.
- the application of electromagnetic waves is made only on the roll which is in the winding phase.
- the electromagnetic waves proper being given that what is sought is primarily the thermal effect within the material, it can be microwaves and high frequencies, in the industrial frequency ranges.
- a textile finishing apparatus in particular of the jigger type, which comprises an enclosure in which is arranged a winder-unwinder system with two directions of movement, a tank for the impregnation bath as well as a system lashing allowing the moving textile material to plunge into the bath.

- the two lateral sides 13, 14 are curved in their upper part in an extension 13a, 14a intended to extend beyond the rollers 5, 6.
- the lashing system 15 comprises three rollers 16, 17, 18 which are mounted inside the tank 11 and whose axes have the same direction as the shafts 3, 4. As can be clearly seen in FIG. 1, two tying rollers respectively 16, 18 are placed near the bottom 12 of the tank 1 1 and the third roller 17 is arranged in height relative to the first two 16, 18.
- the path of the piece of fabric is illustrated in Figure 1 by the arrows
- F is a winding of the first roll 5 from the second roll 6.
- the shaft 4 drives the second wheel 6 in rotation in the direction of the arrow F; the fabric 19 from said second roll 6, passes over the support roller 10, plunges into the impregnation bath 20 contained in the tank 1 1, passes over the lashing system 15 respectively from the roller 18, towards the bottom 12 of tank 11, then roller 17 and finally roller 16; the impregnated fabric 19 passes over the support roller 9 and is wound up to form the first roll 5 around the shaft 3.
- the jigger 1 conventionally comprises means for heating and regulating the impregnation bath 20 , means for controlling the level of the bath in the tank 1 1 with a complementary bath supply circuit.
- the winder / unwinder device 2 is controlled to reverse the direction of rotation of the shafts 3, 4.
- the balance 7 is, in turn, adjusted so maintain a constant application of the support rollers 9, 10 on the outer surface of the two rollers 5,6 so as to avoid the formation of folds and to obtain a constant tension.
- the drive means of the shafts 3, 4 are also speed-regulated to take account of the relative increase in the diameter of the rollers 5, 6 so that the speed of movement of the fabric 19 in the bath 20 is constant.
- the jigger is provided with means for applying electromagnetic waves to the fabric 19 during its winding and / or its unwinding.
- these are industrial type microwaves, that is to say with approved frequencies, namely 2,450 Mhz, 915 Mhz, 433 Mhz. It could also be high frequencies of industrial type of frequencies 13.56 Mhz; 27.12 MHz; 40.68 MHz.
- the device 2 winder / unwinder, tray 11 and the tying system
- the application of microwaves is obtained by means of waveguides which are radiating guides 23, with slots or possibly with antennas.
- These radiating guides 23 making the entire width of the width, four in number in the example illustrated, are placed inside the enclosure 21 near the trees 3, 4 so that the microwaves coming of these radiating guides 23 are preferably directed ent to the outer surface of the fabric 19 constituting the rollers 5, 6 over the entire width thereof.
- the preferential direction of the microwaves emitted by the four radiating guides has been shown in the form of ripples 24, two of them being located opposite the first roll 5 and the other two facing the second rolls 6.
- the radiating guides 23 are supplied using microwave generators not shown, said generators themselves being connected to the jigger control means 1.
- This plate 25 is of course provided with slots 26 allowing the passage of the fabric 19. It can possibly be perforated so as to allow better flow of the excess bath flowing from the fabric 19 during the winding into the tray 1 1, and also the steam from the bath 20.
- the jigger 1 was equipped with two microwave generators of 1.2 kW each capable of supplying respectively two radiating guides 23.
- the tank 1 1 contained four liters of impregnation bath 20, adjustable by a supply circuit with a capacity of 20 liters.
- This laboratory jigger made it possible to carry out tests on a capacity of two kilos of material with bath ratios of between 1: 2 and 1: 10.
- the application of microwaves was carried out using a battery of generators, each generator being connected to a waveguide 28 opening out inside the enclosure 21.
- Each waveguide 28 preferably comprises an extension 29 inside the enclosure 21 suitable for carrying out the adaptation and / or focusing of the wave on the roll.
- the extensions 29 are arranged substantially vertical to the axis
- this loss of temperature is generally of the order of 10 to 15 ° C. Since the action of the microwaves takes place while the roll is being driven in rotation, a hot zone 33 is created over the entire periphery of the rolls on a reduced thickness knowing that this zone is renewed by successive contributions of layer of textile material during the winding In addition the surface zone 33, which is constantly heated by the action of microwaves, prevents heat loss from the core 34 of the roll 32 Thus it can be considered that the assembly of the roll 32, consisting of the textile material to be treated and the bath of the treatment which impregnates it, is constantly maintained at the optimum reaction temperature for the treatment envisaged In these conditions we obtain an optimal kinetics for the treatment
- each generator 29 is controlled by an electronic circuit 35 which is programmed so that only the generators whose waveguides are located facing the wheel are used.
- energy consumption is reduced.
- the operation of the jigger is automatically controlled by varying the speed of movement of the textile material so to keep the power of the generators to its maximum 27
- the electronic circuit 35 is connected to the motor 36 for driving the rewinder - unwinder
- the electronic circuit 35 is programmed so as to determine the speed V of scrolling according to its own parameters to the textile material Certain parameters are introduced by the operator into the electronic circuit, namely the width, the length of the piece, and the nature of the corresponding textile material Other parameters are evaluated during experiments and programmed in the circuit electronics 35, namely the average take-up rate by type of textile material, the temperature difference ⁇ T for a given device type
- the electromagnetic waves act mainly as additional energy supply to more easily heat the textile material and maintain, as has been explained previously, the optimum temperature within the roll.
- Cotton bleaching is obtained by oxidation of the colored compounds naturally contained in the fiber. This was achieved by using hydrogen peroxide as a reagent and operating for one hour at 98 ° C.
- Curve A illustrates the whitening kinetics of a control cotton fabric
- curve B shows that relating to the treatment, under the same conditions, with the application of microwaves, at a power of 2000 W throughout duration of treatment.
- microwaves the degree of polymerization not being modified compared to a conventional treatment.
- the kinetics of dyes were evaluated by varying the microwave power applied to the generators within a range of 500 to 2,000 W
- the final shade of the witness is obtained in a time which is reduced by 50% with an application of 1000 W of microwave; this reduction is even greater when applying 2000 W.
- the final shade, during the action of microwaves is clearly more intense than on the control, with the same formulation.
- This effect could be verified by the applicants by making comparative dyes with microwaves in which the baths had a reduced dye concentration compared to the control. This is illustrated in FIG. 4 which relates to an acetate dye in blue dispersol BN as previously but where the curves D 'and E' relate to dyes with baths respectively at 2% and 2.5% of dye with a power of 2000 W microwave.
- the dyeing of the acetate is carried out with a dispersed dye, diffused in the fiber by surfactants and dispersants at a temperature of the order of 80 to 85 ° C.
- FIG. 5 illustrates the kinetics of fixing the dye to the cotton fabric. It highlights an acceleration of these kinetics as well as obtaining a more intense shade at the end of the dye.
- the absorption coefficient K / S was measured at a wavelength of 430 nm for a yellow gold dye E2R At the end of dyeing, this coefficient was 4.7 for the control and 5.5 for the dyed fabric with microwave application at the right rate with a power of 2000 W
- FIG. 6 shows the increase in the dye yields obtained by application.
- microwaves in accordance with the process of the invention in the context of a tnchromic dyeing in reactive dyes
- These dye yields are evaluated by colo ⁇ mét ⁇ e on the dyed fabric
- the dyes used in this trichromy were respectively yellow gold E2R, blue HERD and the red E7BN
- the dye yield of each of the dyes has been plotted on FIG. 6 on the ordinate, taking the dye yield of the witness as a base. blue and an increase in dye yield of around 40% for red
- the dyeing of the polyamide is carried out with an acid dye, the bath is controlled in pH and in temperature, of the order of 100 ° C., in order to ensure the optimal conditions of the reaction
- a difficulty in dyeing the polyamide is to properly exhaust the dye bath This total exhaustion is all the more difficult to obtain as the shade to be dyed is dark
- a dye with a concentration of 4% in black dye acidol M-SRL has been chosen from so as to increase the potential improvement in the dye yield expected by the dyeing process of the invention.
- the application of the microwaves was deliberately delayed by ten minutes compared to the start of the dyeing, which provides a reliable point of comparison between the control and the dye according to the process
- the dye concentration of the soaping bath which contains the protective colloid was continuously measured.
- the action of the microwaves was postponed to check the correspondence between the treatment of the control and the treatment with application.
- microwaves The duration of soaping has been voluntarily extended to check the saturation of the washing bath, that is to say the total elimination of the non-fixed dye.
- the application of microwaves makes it possible to reduce rinsing and to generate less effluents.
- the present invention is not limited to the exemplary embodiments which have been described above relative to the implementation of the method, as well as to the precise description which has been made of the jigger.
- the application of electromagnetic waves can intervene either only on the roll which is being formed, namely the first roll 5 in the example illustrated, or on the two rollers in winding and unwinding phase.
- the control circuit which allows the automatic change of direction of rotation of the shafts 3 and 4 will trigger successive actuation of the generator (s) corresponding to the radiating guide (s) placed opposite rolls during winding.
- the generators will be constantly in operation.
- the process of the invention makes it possible to reduce or even eliminate the heterogeneities of dyeing between the start and the end of a piece and between the two selvedges, these defects being due to the losses and the heterogeneity of temperature on the material.
- the action of microwaves therefore also allows better reproducibility of the dyes and more generally of all the treatments applied by jigger.
- microwaves in accordance with the present invention, can be implemented in an apparatus of the combi jigger type in which treatments are carried out at a temperature above 100 ° C., under pressure, by example for the treatment of polyester.
