Definitions

  • the invention is based on a method for treating textile goods according to the preamble of claim 1. Furthermore, the invention relates to a device for carrying out the method according to the preamble of claim 27.
  • preparation and finishing agents are applied to textile goods, which are available in the packing or clip-on system, after dyeing, in a subsequent treatment step, the textile goods being used in a sealable or open container that is connected to a circulating device connected.
  • the system is then filled with the treatment liquor, which is composed essentially of water and the agent which is intended to cause the treatment of the textile goods, the chemical, physical / mechanical or surface properties being influenced.
  • the water serves, at least in the course of the further treatment process, only to distribute the treatment agent evenly in the textile body formed by the textile material, by pressing it through the textile body by means of the circulating device under pressure.
  • This known method is in need of improvement, since after the actual refinement process a renewed wet treatment is required and for this purpose the entire liquor volume has to be brought to the treatment temperature by means of heating devices, which has to be kept constant for a given treatment time so that the desired adsorptive binding of the product is achieved the textile body.
  • the known method is unfavorable from an environmental point of view because large amounts of water have to be mixed with the treatment agents necessary for the treatment and, depending on the absorption behavior of the treatment agents, some of them end up in the waste water.
  • the device for performing the method is characterized according to the invention by the features of claim 23.
  • the treatment of textile goods is to be understood to mean any influence on the textile goods with the exception of drying in order to change the chemical, the physical-mechanical or the surface properties, as is the case, for example, when applying finishing agents and other preparations.
  • the treatment agents required for this are not carried out in the new process Water, but transported with the help of a gas stream to and through the textile material to be treated, the gas stream also ensuring the uniformity and uniform distribution of the treatment agent in the textile material or the textile body formed by it.
  • the treatment agent is added to the gas stream in finely divided form, so that an aerosol is formed which then penetrates the textile body.
  • the resulting aerosol has a very low viscosity, low drive power is sufficient to be able to press the aerosol through the textile body and the distribution of the treatment agent in the textile body is supported.
  • the specific heat of gas is lower than that of water, which means that less energy is required to achieve and maintain the necessary working temperatures. It may even be possible to dispense with special heating devices, since the compression effect of the circulating device for the gas ensures the necessary temperature increase.
  • only a very small amount of wastewater is produced in the new process, namely only in accordance with the moisture removed in the textile body or the amount of water that is necessary to generate and maintain the aerosol.
  • the gas stream for treating the textile material can be the same as that used for drying the textile material, so that a gradual drying of the textile material is achieved simultaneously during the actual treatment. In the simplest case, air is used for this.
  • composition of the gas stream with the finely divided treatment agent changes before the flow through the textile material through precipitation on the tube and boiler walls and after the outlet from the textile body the treatment agent is separated from the gas stream, this separated treatment agent can expediently be added in finely divided form on the one hand to reduce the pollution of the wastewater and on the other hand to use the treatment agent more economically.
  • the flow direction through the textile body is reversed at least once during the entire treatment time, so that the treatment agent can penetrate into the textile body from both sides.
  • a textile body which can be flowed through in a particularly favorable manner is obtained if the textile material is wound onto carriers, preferably in the form of coils, which can be plugged onto material carriers in pressure vessels of pressure dryers in a known manner.
  • carriers preferably in the form of coils, which can be plugged onto material carriers in pressure vessels of pressure dryers in a known manner.
  • Stable operation of the treatment process at the lowest possible temperatures is achieved if the regulation of the temperature is regulated exclusively by changing the cooling after reaching a specified temperature value.
  • the desired fine distribution of the treatment agent can be achieved very easily by spraying with water, the treatment agent optionally being emulsified with water beforehand.
  • the addition of the treatment agent can be kept constant during the entire process time or can be changed according to a program, depending on how the migration of the treatment agent proceeds in the textile body.
  • This regulated or controlled addition of the treatment agent also includes an impulse addition.
  • the device for carrying out the method is preferably a pressure drying system with a pressure vessel which receives the textile material and which contains a gas routing device which is connected to a gas circulation device outside the boiler via lines.
  • a gas routing device which is connected to a gas circulation device outside the boiler via lines.
  • one of the lines contains a device for the finely divided addition of treatment agents, through which the gas circulating in the system flows.
  • the device for finely distributed addition of the treatment agent is expediently arranged behind the compressor.
  • an inside / outside or an outside / inside flow can be achieved in the textile body, which leads to a particularly uniform distribution of the finishing agent even in thick textile bodies in a relatively short time.
  • Fig. 1 is a system 1 for the simultaneous treatment and drying of textile goods, such as fabrics, knitwear, threads, yarns, ridges and the like. illustrated.
  • the system 1 is constructed similarly to a through-flow pressure drying system and has a pressure vessel 3 which can be closed with a cover 2.
  • a material carrier 4 onto which textile articles 5 can be attached.
  • These textile goods 5 are, for example, bobbins or spools of yarn, crests, knits, fabrics, knitted fabrics and the like, which are attached in a known manner to slip spindles, not shown.
  • the material carrier 4 is essentially hollow and fluidly connected to a switchable pipe section 6, which can optionally be connected in a sealed manner with its free end to a boiler connection 8 or a boiler connection 9; it acts like a multi-way valve.
  • a gas circulation device 11 is connected outside the pressure vessel 3, which contains a line section 12 which connects the connection 8 with an inlet side 13 of a heat exchanger 14 serving as a cooler, from which the inflow via line 12 Air can flow out through an outlet 15.
  • the cooler 14 also contains a schematically indicated pipe coil 16 through which a cooling medium flows and which is connected at one end via a continuously adjustable valve 17 to a source (not shown) for the cooling medium.
  • the flow rate of the cooling medium flowing through the coil 16 can be continuously changed in this way from zero to a maximum value in order to achieve different cooling effects.
  • a water separator 19 connects to the cooling device 14 via a line section 18, the inlet 21 of which is fed from the line 18 and the outlet 22 of which is connected to a line section 23 leading away.
  • the liquid separator 19 contains a drain line 25, which can be closed via a condensate drain 24, for drawing off accumulated liquid.
  • the air circulating in the system 1 flows from the liquid separator 19 to a suction side 26 of a compressor 27, the pressure or outlet side 28 of which feeds a line section 29.
  • the line section 29 connects the outlet or pressure side 28 to an inlet 31 of an atomizer device 32, which is connected with its outlet 33 via a line section 34 to the boiler connection 9.
  • a pipeline 36 opens into the atomizer device 32 and is used to supply a liquid or emulsion to be atomized or atomized from a supply (not shown).
  • the amount of liquid or emulsion supplied, which serves as a treatment agent to act on the textile article, is controlled by means of a controllable valve 37.
  • two pipelines 41 and 42 which can be shut off via solenoid valves 38 and 39, open into the line section 12, of which the pipeline 42 leads to a compressed air source, not shown, while the line 41 if necessary, leads outside through a filter.
  • the entire system 1 is controlled by a schematically indicated control device 43, the individual electrical connecting lines between the control device 43 and the various valves are omitted from the drawing for the sake of clarity.
  • liquid In the event that liquid accumulates undesirably in the pressure vessel 3, it contains a depression 47 in its base, from which the excess liquid can be disposed of via a line 48.
  • the disposal line 48 is shut off via a condensate drain 49 to prevent compressed air from escaping.
  • the system described is operated as follows: The wet textile material is introduced into the pressure vessel with the material carrier 4 with the cover 2 open.
  • the columns formed by the textile body 5 are secured on the material carrier 4 in a known manner by head closures and are closed in terms of flow, so that medium which flows through the pressure vessel 3 during operation of the system 1 must inevitably flow through the textile body 5.
  • the cover 2 is closed and the central control device 43 is activated. If not yet done, this causes all taps and valves to close before opening valve 39 in order to allow compressed air to flow into the system 1 circuit.
  • the control device 43 After reaching a desired air pressure, for example 7 bar, the control device 43 shuts off the valve 39. Before the system 1 is charged with compressed air, the control device 43 has switched on the compressor 27, which has immediately started working in the circuit of the system 1 contained air to circulate, the textile body 5 is first dewatered mechanically due to the air pressed through it. The water in the pores of the textile body 5 is pressed out by the air, which the compressor 27 presses via the line 34 into the pressure vessel 3. The circulated air passes through the connection 9 into the interior of the pressure vessel 3 and from there as an outside / inside flow through the textile body 5 into the interior of the material carrier 4. Another flow path for the air does not exist within the pressure vessel 3.
  • the air flowing out of the textile body 5 has pressed out the water and reaches the connection 8 via the line section 6, from where the air reaches the liquid separator 19 via the line 12 through the initially switched off cooling device 14.
  • the water that is carried along is separated off there.
  • the air largely freed of water is finally sucked in again on the suction side 26 of the compressor 27 and fed to the pressure vessel 3.
  • the control device 43 uses the temperature sensor 44 to determine whether a predetermined temperature has been exceeded on the upstream side to the textile body 5, it opens the valve 37, as a result of which a treatment agent flows in a metered manner into the atomizer device 32 via the line 36.
  • the amount of the treatment agent supplied is determined, for example, by calibrating an atomizer nozzle or a throttle or else a metering pump, so that there is a predetermined admixture of the treatment agent to the air flow that passes through the atomizer device 32.
  • the treatment agent is in flowable form and, after its atomization or atomization in the atomizer device 32, together with the air flowing through it, an aerosol is produced which is now passed through the textile body 5 under pressure.
  • the treatment agent for example a finishing agent, a preparation or some other finishing product, which acts on the textile body 5, is transported exclusively by the circulating air in this method.
  • the central control device 43 In order to prevent the temperature in the system 1 from increasing further over time, the central control device 43 increasingly begins to open the controllable valve 17 so that cooling medium can flow through the cooling device 14 in order to remove the moist and cool down warm air so far that after the compressor 27 the air has a desired temperature at the measuring location of the thermometer 44.
  • the dew point When the outflowing air is cooled, the dew point is possibly fallen below and the water is partially separated from the air, which it has absorbed when flowing through the textile body 5.
  • the system 1 described achieves the air temperature after reaching a predetermined limit value exclusively by regulating the cooling device 14, the air entering the textile body 5 has a relatively high saturation, which prevents overdrying in the textile body 5 during the treatment process as a result of the flowing through warm air arise.
  • the central control device 43 switches the line 6 from the port 8 to the port 9.
  • the circulating air will now occur as an inside / outside flow in the textile body 5 and preferably supply the treatment agent to the inner regions of the textile body 5.
  • the central control device 43 switches off the supply of the treatment agent by closing the valve 37.
  • the treatment agent is evenly distributed in the textile body 5 by the moist air flowing through it and at the same time the remaining residual moisture is removed from the air flowing through, in order to be separated as liquid water in the liquid separator 19 after cooling the air below the dew point on the cooling device 14. Falling below a specified temperature difference between the two temperature measuring devices 44 and 45 is a sign of the achievement of a desired degree of drying.
  • the control device 43 will then shut down the compressor 27 and release the pressure from the system 1 by opening the valve 38.
  • the lid 2 can now be opened and the textile body 5 can be removed.
  • thermodynamic behavior of the system 1 is described below using a cherry tree diagram according to FIG. 2.
  • the temperature in the line section 34 that is to say between the outlet 28 of the compressor 27 and the connection 9 of the boiler 2 remained essentially constant.
  • This constant temperature can also be achieved by introducing large amounts of water by means of the treatment agent in that the treatment agent is heated to a correspondingly high temperature. Otherwise, any cooling of the compressed air by the treatment agent is insignificant, since the temperature is not measured at the outlet of the compressor 27, but before the connection 9 of the boiler 2.
  • the new method has considerable advantages in that two process steps, namely the application of treatment agent and drying, can be carried out virtually simultaneously.
  • FIG. 2 The operating state after the system 1 has been charged to 7 bar and a steam supply has been switched on is illustrated in FIG. 2 in a heat diagram 51.
  • the air is first heated polytropically by the compressor 27 without changing the water content, as a section 52 shows.
  • the air has a lower degree of saturation but a higher temperature with a constant water content.
  • the air can both be further heated and additionally moistened, as can be seen in a section 53.
  • the air thus set in its physical values flows through the textile body 5, cooling itself while absorbing water while flowing through the textile body 5.
  • the textile body 5 has a non-hygroscopic material and that the cooling limit temperature is actually reached, ie the air which flows out of the textile body 5 is actually saturated and cannot absorb any further water at the given temperature. Their saturation content ⁇ is one.
  • the water absorption with simultaneous cooling is illustrated in the diagram 51 by a section 54.
  • Temperature is cooled down in order to condense out the excess water so that it can be separated in the subsequent water separator 19 before the air is fed again to the suction side 26 of the compressor 27.
  • the heat diagram 51 therefore follows in section 55 of the saturation curve.
  • control valve 17 is regulated to a predetermined maximum value via the central regulating and control device 43, so that a significant cooling effect that is close to the maximum value is achieved.
  • the system 1 remains until the regulating and control device measures a temperature in the circuit which is above a predetermined limit value via the temperature sensor 44. As soon as this limit value is exceeded, the regulating and control device 43 switches off a steam supply which arises, as a result of which a further supply of heat to the circuit is switched off. At the same time, the regulating and control device 43 regulates the coolant flow in the cooling device 14 by appropriately closing the control valve 17, to the extent that the temperature increase in the air at the compressor 27 between the inlet and outlet sides 26, 28 becomes greater than that Lowering of temperature, which occurs due to the water absorption in the textile body 5 and the cooling on the cooling device 14. This results in a triangular heat diagram 56 shown in FIG.
  • the speed at which the shift in the heat diagram occurs depends on how the regulating and control device 43 adjusts the control valve 17. The further it is closed, the less coolant can flow through the coil 16 and the less the air flowing out of the winding body 5 is cooled before it is supplied to the compressor 27 again. There is therefore a more or less rapid temperature increase in the circuit.
  • This operating state is maintained until a further temperature limit is exceeded, which the regulating and control device 43 in turn determines with the help of the temperature sensor 44 in the line section 34. As soon as this limit value is exceeded, regulation takes place via the regulating and control device 43 the way that the temperature in the line section 34, ie at the entrance of the textile body 5 is kept constant. Without changing the output of the compressor 27, this regulation is achieved exclusively by changing the control valve 17 and thus the cooling effect of the cooling device 14.
  • This operating state of the system 1 is illustrated by state diagrams 61 and 61 '.
  • the regulating and control device 41 can start a humidification device. If the amount of water absorbed by the air is equal to that Is the amount of water that is separated on the water separator 29, the textile body 5 is finally no more water removed, but the process remains stationary. Since there are no other energy sources other than the power of the compressor 24, only a relatively small amount of heat needs to be removed from the cooling device 14 as well, which is why the system works overall in a cost and energy saving manner, although it remains controllable overall.
  • the state diagrams 61 and 61 'according to FIG. 2 can also be seen that the temperature at the outlet of the textile body 5 can be used as a criterion for the dried state. With increasing drying of the textile body 5, the temperature of the air flowing out of the textile body 5 increases. In order to detect the dried state, the temperature sensor 45 is provided in the line section 12.
  • the pressure in the system can, for example, be reduced from 7 bar to 5 bar, as shown in FIG. 3.
  • the state diagram is also shifted to the right, at the same time the degree of saturation of the air at the entrance to the textile body 5 increases despite the air temperature in the line section 34 being kept constant.
  • the system 1 shown also allows operation with a constant degree of saturation of the air entering the textile body 5 if, instead of the temperature sensor 44, a humidity sensor is used.
  • the system 1 is regulated by the regulating and control device 43 in such a way that on the upstream side of the textile body 5 the air has a constant degree of saturation, for example 0.5, over the entire operating period.
  • a cooling phase begins by gradually reducing the air temperature in the line section 8, which is accomplished by increasing the cooling effect on the cooling device 14.
  • the reference variable with which the measured value occurring at the temperature measuring device 44 is constantly compared in order to change the control valve 17 is changed in accordance with a desired predetermined program within the regulating and control device 43.
  • the system 1 remains controllable, the operation taking place at a low power level.
  • FIG. 5 shows a further variant of the system 1 according to FIG. 1 in order to have additional intervention and control options in the process.
  • the same reference numerals are used below without further explanation.
  • a metering pump 71 which can be optionally switched on and off by the control device in order to selectively suck the treatment agent in appropriate quantities from a storage container 72 and to atomize it at the outlet of the line 36.
  • the outlet of the line 36 is, as before, in the atomizer device 32, in which a water line 73 also opens, in order to additionally spray water in the atomizer unit 32.
  • the line 73 is to be shut off by a controlled valve 74 or to be opened to a greater or lesser extent in order to adjust the quantity on the one hand and the droplet size on the other hand.
  • a steam supply device 76 in the line 29, which allows steam to be supplied to the air circulated in the system 1 via a line 77 which is connected to a steam generator (not shown) and by means of a valve 78 can be shut off by the control device 43.
  • the system 1 from FIG. 5 differs from that according to FIG. 1 by a series of measures in order to return treatment agents which have deposited at different points in the system 1 to the storage container 72.

  • Such a type of conditioning is required, for example, if it is assumed that the textile body is dry and the treatment agent to be applied requires a greater moisture content in order to achieve adequate migration.
  • the system 1 is started in the same manner as described above, but the central control device 43 first opens the valve 78 before the treatment agent is added in order to allow steam to flow into the system. This achieves two things: First, the temperature of the air circulating in the system increases, and moisture is also added to the textile. It is also advisable to blow in steam when it is only a matter of reaching the working temperature as quickly as possible so that the treatment agent can be added as soon as possible.
