Description

Rope type fabric cleaning method and apparatus {METHOD AND DEVICE FOR FLUSHING TEXTILE FABRICS IN ROPED FORM}

In wet processing of rope-type fabrics in a JET processing device, such as a JET batch dyeing machine, the fabric in the form of a landed rope is circulated by a transfer nozzle system in the form of a JET nozzle in which the transfer medium flow is driven, in which case the transfer medium flow Imparts a feeding movement in a pre-designated circulation direction to the take-off rope. In that case, the conveying medium is a treatment dye liquid to which additives can be mixedly added depending on the process in many apparatuses, and the treatment dye liquid may be at different temperatures during the course of the process.

Each such wet process requires a cleaning process that has affinity for the fabric and must wash away the material adhered to or on the surface of the fabric, so that the fabric can be unwound, bleached, sensitized in advance or simultaneously with the cleaning method. It is transferred into a solution, emulsion, or dispersion through a unique preparation process such as the like. Strictly speaking, in practice, three different methods are usually used for washing fabrics, a dilution process in which the concentration of dirt particles to be washed out in the wash liquid is reduced. It is described, for example, in Maryland Fabric Report 6/1977, pages 428 to 433.

In the so-called charge washing method, after filling the washing liquid bath in the container, the take-off rope is circulated and the washing liquid bath is discharged again after a predetermined number of take-off rope cycles. As a result, mixing of the waste loading dye solution and the washing liquid on the fabric occurs in the washing liquid bath. Only after several bath changes will the desired cleaning result be achieved.

In another method, washing is carried out between two different levels of wash liquor contained in the container. In that case, the circulation movement of the landed ropes during the cleaning process is not interrupted by the filling and discharging of the treatment liquid. Instead, the wash liquor is circulated by a circulation pump, typically a dye liquor pump, for the duration of the treatment, by appropriately controlling the wash liquor flow into and out of the wash liquor to ensure that the upper and lower water levels (smooth operation of the Cleaning liquid level coming and going between) is maintained in the container. The wash results are determined by detecting dirt contamination in the drained wash liquor, similar to the charge wash.

Finally, the third method is an overflow wash. In such a cleaning method, the cleaning liquid, which is usually water, is continuously supplied to the dirt-loading treatment dye liquid contained in the container during circulation of the landing rope, while the excess treatment dye liquid diluted by the washing liquid is determined by the overflow tube. Continue to discharge. In that case, the wash results are given by successive dilutions of the treatment bath. Such results can be investigated by appropriately monitoring the gradually diluted treatment dye liquor discharged via the overflow line.

Among such methods at the time of washing, the charging washing method and the washing method between two different water levels are most efficient in terms of washing liquid consumption, that is, in terms of water consumption in general. Water consumption in overflow washing is highest due to its principle, and such a method of washing is therefore inefficient in terms of washing liquid consumption.

Dyeing machine water consumption is a key criterion for the economics of wet refining in many industrial countries. However, economics are also particularly affected by the washing time that is relied upon to achieve each scheduled cleaning result. Relatively long cleaning times make the overall treatment time correspondingly long, thereby limiting the amount of landfill that can be obtained in the device.

In such a type of nozzle treatment apparatus, the cleaning liquid is required per unit time irrespective of the cleaning method used, since the driving of the endless landed rope is also performed by the hydrodynamic method by the dye liquid propelled to the transfer nozzle. It will depend heavily on the amount of liquid needed to drive this landing rope. In other words, a considerable amount of wash liquid, which is typically wash water, is required only for driving the driven rope. Omitting the driven rope with the dye liquid circulated by the circulation pump during the washing process, and introducing the fresh wash liquid as the transfer medium to the JET nozzle, thereby driving the driven rope by cleaning and material transfer by means of Although attempted, such a method is very uneconomical due to the large wash water requirements and poor liquid exchange between the fresh wash water flowing through the nozzles and the dirt-loaded dye liquor on board the rope.

Accordingly, it is an object of the present invention to keep the consumption of the washing liquid, i.e., the normal consumption of the washing water and the time required to carry out the washing process low, and that the production costs of the whole wet purification method requiring the washing process are minimized. It is to provide a rope-type fabric cleaning method in the JET treatment apparatus, which can adjust the wash water consumption and time requirements according to the conditions.

Such an object is achieved by the method according to the invention with the features of claim 1.

In the present invention, in the JET processing apparatus according to the aerodynamic principle, the transfer of the endless landed rope is performed by pushing the gaseous transport medium to the venturi transporting nozzle, and in some cases supported by a winch driven from the outside. The transfer of is independent of the treatment dye liquor and therefore starts with the recognition that new possibilities are given for the cleaning of the surface.

Thus, in a novel method of washing rope-like fabrics, the fabric in the form of an endless landed rope is circulated by a gaseous transfer medium using a venturi transfer nozzle in a closed vessel. The fabric is placed under the action of the cleaning liquid in such a way that the cleaning is performed by the constantly flowing cleaning liquid. In that case, the washing liquid input per unit time and / or the landing rope speed are controlled in accordance with the purpose depending on the data specific to the fabrication of the fabric, the data specific to the apparatus, and the data specific to the method. The dirt-loading washing liquid flowing out from the transfer nozzle is taken out of the container.

In practice, this means applying fresh wash water, for example, directly to the wash water line, in the form described above, via a pump and heat exchanger in the landed rope propagation path upstream and / or downstream of the transfer nozzle. After that, the outflowing dirt-loading wash water is immediately discharged. This results in a significantly reduced amount of wash water compared to the hydrodynamic JET treatment apparatus mentioned at the beginning, while at the same time shortening the wash time is achieved.

This opens the way for optimizing the washing liquid consumption and washing time per unit time depending on a given criterion. In a very preferred configuration of such a novel method it is processed such as, for example, the weight of the landing rope, the substrate and data specific to the fabrication of the fabric, such as decoration, structural conditional data of the transfer nozzle, such as diameter, nozzle length, etc., and the circulation speed of the landing rope. This can be done in the form of determining a cleaning method from the data specific to the cleaning method and a simulation model of the results. Controlling the amount of washing liquid input through the transfer nozzle per unit time and the speed of the landing rope is made by a computer depending on such a predetermined calculation model.

Such a computational model is implemented by data collected during the washing process. Starting therefrom, the calculation model is verified by comparison with the data obtained in the actual cleaning operation by a simple test.

Indeed, the results of the cleaning process are examined by color or by simple tests performed manually. Such a test may be, for example, weaving a landed rope and receiving water coming off of it to measure the residual chromaticity. Another approach is to measure, for example, the pH value or electrical conductivity of the effluent-loaded wash water. Such testing is typically done directly on the device by withdrawing the dye solution or stopping the device. Subsequently, once the skin is finally wet treated (processed and purified), it performs most of the consistently standardized quality control (wear wear reliability, laundry reliability, bond reliability) that can be distributed worldwide and the results can also be compared to each other.

Now, the method according to the invention for washing the skin directly with the washing liquid can be configured to monitor the results of the washing process continuously or online at intervals. The data specified for each cleaning result thus examined is entered into the control device, and in particular into the calculation model, to automatically change the cleaning process or to confirm the end of the cleaning process. The change in the washing process can be done in such a way that, for example, at the beginning of the washing process, i.e. at the first circulation of the landing rope, the amount of washing liquid introduced into the landing rope is different, in particular higher, at the end of the washing.

Since such a new cleaning method washes the skin directly in the wash liquid flowing through the vessel, the dirt payload in the dirt loading wash liquid is a measure of the resulting cleaning effect. To measure such dirt payloads, for example, the following sensors can be used:

-A sensor that measures the pH value of the dirt-loaded washing liquid that washes away acid and alkali,

-A sensor that measures the electrical conductivity of the dirt-loaded wash solution to wash off salt,

-Turbidity sensor for measuring residual chromaticity in dirt loaded wash liquid.

The measurement of the dirt payload can be done in the wash water discharged from the vessel and / or directly on the take-off rope.

In order to determine the end of the cleaning time, the following criteria, in particular measured by a suitable sensor and / or calculated by computer, can be cited:

At least one variable specified for the dirt payload in the dirt loading wash liquid, such as a given absolute measurement, such as its turbidity, electrical conductivity, pH value,

A predetermined ratio between the initial and final values of one or more variables specified for the dirt payload in the dirt load wash,

The change over time of the variable specified for the dirt payload in the dirt load wash,

Answer the question of how the measurement has changed per given unit of time by the first-time derivative of the measurement of that variable. Since all wash procedures end in a flat curve indicating that dirt particle concentrations rarely change with the progress of the wash time as seen in the graph, the first time derivative of the above-described measurements can also be used as a reference for the end of the wash time.

By integrating theoretically calculated and actually measured values into the above-described calculation model, the cleaning process can be further optimized. For example, one may consider optimizing the wash time early in the wash process, where a large drop in concentration is rapidly obtained with large amounts of wash liquor. At the end of the washing process, when the difference in concentration in the effluent-loaded wash liquor is no longer so large for each of the circulation cycles, it is advantageous to work with a smaller amount of wash liquor, instead taking rather more time. In either case, the result results in an optimized cleaning process in terms of the amount of cleaning time required as well as the cleaning time required.

In actual wet processing operations, ie in dyeing plants, such optimization is more economically important. For example, in some industrial countries dyeing plants work at relatively low production and high water costs, while in some industrial countries high production and very low water costs are imposed. There may be areas where production increases are possible only if the process water is distributed to the dyeing plant and thus a high production and thus higher yield can be obtained by the constant amount of water distributed.

The method according to the invention makes it possible to optimize the cleaning process when the data necessary for the cleaning process are known. In particular, the control system can calculate the water consumption or the required production time by itself depending on each given production conditions such as water price, production capacity and the like. The control system only needs to be designated by the operator or programmer of the wet processing device as to whether the cleaning process should be optimized in terms of water consumption or in terms of production time.

Another configuration of the method according to the invention falls on the subject of the dependent claims. It will also be apparent from the following description of the embodiment of the method according to the invention shown in the accompanying drawings.

The high temperature (HT) batch dyeing machine shown schematically in FIG. 1 of such an accompanying drawing has a cylindrical pressure-resistant container 1 through which an operating opening 2 can be closed by a lid 2, the operating opening thereof. Through 2, the landing rope 4 can be introduced. The landed rope 4 is introduced into the venturi conveying nozzle 6 via a winch 5 driven from the outside, and the folding device 7 is connected to the venturi conveying nozzle 6. The folding feast 7 folds down the landed rope 4 flowing out of the transfer nozzle 6 and puts it in the reservoir 8, from which the endless landed rope is pulled out again through the winch 5. The winch 5 and the transfer nozzle 6 are housed in a housing member 9 which is liquid sealed to the container 1. The landed rope 4 is introduced through the operating opening 3 and then joined at an end with an endless landed rope.

A gaseous conveying medium is propelled to the conveying nozzle 6 to circulate the continuous landed rope 4 in the circulation direction indicated by the arrow 10. The conveying medium is in this case air or air / vapor mixture which is sucked from the vessel 1 via the fan 11 and the suction line 12 and fed to the conveying nozzle 6 via the pressure line 13.

At the bottom of the vessel 1 is arranged a dye liquid outlet 14 which contains a dye liquid sieve 15 and is connected to the suction side of the fuel liquid circulation pump 17. The pressure line 18 includes a heat exchanger 19 and is passed through a feed nozzle 6 via an intermittent valve 20. The dye liquid circulation pump 17 allows the dye liquid sucked from the container 1 to be circulated via the transfer nozzle 6 and the container 1. A bypass line 22 is located in parallel with the heat exchanger 19 and the dye liquor circulation pump 17, the bypass line 22 comprising a shutoff valve 23, which connects the dye liquor outlet 14 to a pressure line. (21).

Finally, an additive container 24 containing chemical additives in an aqueous solution, emulsion, or dispersion is provided, wherein the chemical additive is supplied to the dye solution circulation pump 17 via the additive pump 25 and the connection line 26. May be supplied to the suction line 16.

Batch dyeing machines which operate according to the aerodynamic principles described so far are known. If it is necessary to clean the landing rope 4 during the course of the treatment, the following measures will be taken:

The inlet valve 28 in the discharge valve 27 of the dye liquid outlet 14 and the suction line 16 of the dye liquid circulation pump 17 is opened. Washing water flows into suction line 16 via inlet valve 28, as indicated by arrow 29. The introduced wash water can be mixed with the additives that facilitate or support the cleaning process from the additive container 24 before entering the transfer nozzle 6 and can be brought to the desired washing temperature in the heat exchanger 19.

When the fan 11 is turned on to feed the conveying air stream circulated through the lines 12 and 13, the conveying nozzle 6, and the container 1, the conveying air stream passes through the driven rope 4 in the circulation direction ( 10).

The washing water introduced into the transfer nozzle 6 is applied to the land forming the landing rope 4 at the transfer nozzle 6. The landing rope 4 taken out from the winch 5 into the reservoir 8 is soaked with the dirt-loading dye liquid when entering the transfer nozzle 6, and the dye liquid is carried into the transfer nozzle 6 by the landing rope. Will be. In the transfer nozzle 6, mixing of the dirt-loaded dye liquid reaching the transfer nozzle by the landing rope and the amount of washing water supplied by injection via the pressure line 21 is achieved.

The dirt-loaded washing water flowing out from the transfer nozzle 6 is collected in the container 1 and then discharged via the dye liquid outlet 14 and the shutoff valve 27, as indicated by the arrow 30. The suction line 15 is cut off with respect to the suction side of the dye liquid circulation pump 17 by a shutoff valve 31.

As the number of circulation of the landed rope 4 is increased, the dye liquid contained therein is gradually diluted by the washing water injected through the transfer nozzle 6 until the result of each washing is finally obtained. The appearance of such a cleaning result can be confirmed online by the sensor means 32 flowing through the dirt-loading washing water discharged from the container 1. Such sensor means 32 monitor, for example, the pH value, electrical conductivity, and turbidity of the discharged wash water, and input the corresponding signals specified for such variables into the control system's computer 33 as data.

Once the desired wash effect is obtained, the supply of wash water is stopped again and the batch dyeing machine is set for the subsequent wet treatment step.

During the cleaning process, the landed rope is driven by the air flow fed from the fan 11 regardless of the amount of wash water injected. By controlling the fan 11 appropriately, the circulation speed of the landed rope 4 can be changed at any time, while the intermittent valve 20 can change the amount of washing water injected per unit time under the control of the computer 33. .

Alternatively or additionally, the computer 33 may be connected downstream of the fan 11 to change the circulation speed of the landed rope 4 by controlling the throttle valve 34 located in the pressure line 13. The amount of wash water injected may be altered by the control action on the circulation pump 17, as shown in FIG. 1.

The amount of the dirt-probeing dye liquid introduced into the conveying nozzle 6 by the landed ropes 4 substantially depends on factors such as the weight, the substrate, and the decoration of the landed ropes 4. From that, it is calculated how many liters of liquid the landing rope can absorb. The amount of liquid actually absorbed is converted in proportion to the weight of the landed rope, yielding a so-called "pick-up". Also, such amount depends on the speed of the landing rope 4. That is, the amount of the dirt-loaded dye liquid introduced into the conveying nozzle 6 by the landing rope is directly dependent on the circulation speed of the landing rope.

Based on such recognition, a computational model can be developed that simulates the results of washing. Such calculation models are verified by testing against actual situations. 2 shows the results of such a comparison test between theoretical calculations and actual measurements.

The dirt concentration in the dirt-loaded washing water discharged from the dye liquid outlet 14 is written in grams per liter according to the number of circulation of the landed rope 4. Both curves show that the concentration drops during the first cycle of the landing rope and approaches the minimum residual value in the form of asymptotes as the number of cycles of the landing rope increases. It is clear that the agreement between the calculation and the actual measurement is good.

By the calculation model thus obtained, parameters for the washing process can be optimized by simulation calculation. 3 to 5 show the results of such a calculation for one embodiment.

The underlying embodiment of FIGS. 3 to 5 has an average weight per square meter of 250 gr / m 2 and the following parameters are applied to the cotton knitwear:

Pickup (%) 330

Storage Load (kg) 200

Initial dirt payload (gr / ltr) 35

Residual dirt payout at end of cleaning time (gr / ltr) 3

From there, the following values (Table 1 and Table 2) for washing time in minutes and water consumption in liters per kilogram are given, which show the change in percentages starting from a given device setting. It is shown graphically in the diagram.

Flush time (minutes) Injection volume (ltr / min) speed 100% 250% 400% 550% (m / min) 500% 32.9 14.3 10.0 8.6 400% 33.9 16.1 10.7 8.9 300% 35.7 16.7 11.9 9.5 200% 35.7 17.9 14.3 10.7 100% 42.9 21.4 21.4 14.3

Water consumption (ltr / min) Injection volume (ltr / min) speed 100% 250% 400% 550% (m / min) 500% 6.6 7.1 8.0 9.4 400% 6.8 8.0 8.6 9.8 300% 7.1 8.3 9.5 10.5 200% 7.1 8.9 11.4 11.8 100% 8.6 10.7 17.1 15.7

Such values and the diagram according to FIGS. 3 and 4 show that the wash time can be significantly shortened by a change in the wash water supply, while on the other hand the wash water consumption can be reduced by an extension of the wash time. In addition, it should be noted that if the device is underloaded, the cleaning time is automatically reduced.

As can be seen from FIG. 5, as the washing time is reduced, washing water consumption must be increased to obtain a predetermined constant washing effect. In the first 1/3 part (left third part), the required cleaning time is drastically reduced. In the last one-third (right one-third), washing water consumption increases dramatically, although the washing time is only slightly reduced. For this reason, the optimum working area is located in the middle third, where the washing time can be significantly reduced while the wash water consumption is almost unchanged.

The values listed in Tables 1 and 2 can be obtained, for example, by varying the amount of wash water per unit hour (injection volume) and the speed of the take-up circulation, as indicated by the blackened sections of the table, while at the same time The amount of wash water required also shows an increase of only 38%.

The illustrated embodiment can significantly increase the amount of production and the resulting yield, while at a lower wash water cost compared to the burden of increased wash water consumption due to a shorter wash time, while an increase in wash water costs due to an extended wash time. The city has shown that using additional device capacity can significantly reduce cost requirements.

In the above description, as mentioned in the description, generally referred to as "washing liquid" was conventional wash water. However, if fundamentally beneficial in terms of the fabric to be cleaned, other cleaning solutions may be used, such as cleaning solutions of the organic species.

In the embodiment described above, the cleaning liquid is injected into the transfer nozzle 6 and applied to the landed rope. Alternatively or additionally, however, it is also possible to carry out a new cleaning method in the form of applying washing liquid to the landing rope propagation path and / or applying to the landing rope 4 behind the transfer nozzle 6. For example, it is shown schematically in FIG. 1. For example, a washing liquid line 34 from the pressure line 21 is passed through the housing 9 at the top of the winch 5, which has an intermittent valve which can be controlled and operated by the computer 33. 35 is located. Thereby, it is realized that the landing rope flowing into the conveying nozzle 6 is already loading the washing liquid.

The rinse line 34 does not necessarily have to pass through the area above the winch 5. Depending on each given situation, the inlet of the wash liquid line 34 may be located anywhere between the winch and the nozzle gap of the venturi conveying nozzle 6. In addition, the inlet of the washing liquid line 34 is located in the traveling path (vertical traveling path) of the landing rope 4 placed between the reservoir 8 and the winch 5, and the landing rope 4 is the winch 5. It is also contemplated that embodiments in which the cleaning liquid is already applied to the landed rope 4 before reaching). 1 is shown by a dashed dashed line, which shows a pressure line 34a in which an intermittent valve 35a is located, which can also be controlled and operated by the computer 33.

In addition, a pressure line 36 may be provided which is routed through the traveling path of the landing rope behind the transfer nozzle 6, in order to introduce the washing liquid into the landing rope 4, which pressure line 36 is for example. It is branched from the pressure line 21 and includes an intermittent valve 37 which can be controlled and operated by the computer 33. As such, it is possible, alternatively or additionally, to apply the cleaning liquid to the landing rope 4 behind the transfer nozzle.

The dirt-loading washing liquid discharged from the landed rope 4 is collected in the yogi 1 and discharged via a sump and a shutoff valve 27. Alternatively, however, measures may be taken so that the dirt-loading wash liquid is removed from the container in a batch, that is, the wash liquid is collected in the container and then contributed for later reuse.

Finally, it will be mentioned that the sensor means 32 confirming the appearance of the cleaning results do not necessarily have to be arranged behind the shutoff valve 27 to monitor the discharged dirt-loading cleaning liquid. The measurement and determination of the data specified for the dirt payload may be done directly on the landing rope 4.

In the rope-type fabric washing method according to the present invention, the fabric in the form of an endless landed rope is circulated by a gas-type transfer medium using a venturi transfer nozzle in a closed container, and the fabric is washed with a constantly flowing washing liquid. By putting it under the action of the washing liquid in the way that it is done, it takes a significantly reduced amount of washing water compared to a hydrodynamic JET treatment device, while at the same time achieving the effect of shortening the washing time. In addition, there is a way to optimize the washing liquid consumption and the washing time per unit time depending on a predetermined criterion.
