Description

In the wet treatment of strand-like textile material on JET treatment machines, for example on JET piece dyeing machines, the textile is in the form of an endless warp in a closed container by means of a Circulated transport nozzle system in the form of a JET nozzle, which acted upon with a transport medium flow is that the goods strand his advancing movement in the given Circumferential granted. The transport medium is included For many machines, a treatment fleet that is process-dependent Additives can be mixed and during the the process flow to different temperatures can be brought.

In any such wet refining process, rinses are required in which substances that have an affinity to have the textile goods, located in this or stick to their surface, have to be washed away, after being through your own preparation processes, like Desizing, bleaching, washing, saponifying, etc. first or simultaneously with the rinsing process in solution, emulsion, or dispersion. For rinsing the textile goods, which is exactly a dilution process acts in the course of which the concentration of the wegzuspülenden Dirt particles lowered in the rinse liquid In practice, there are essentially three different ones Procedures used. This is e.g. explained in Melliland Textile Reports 6/1997, pages 428 to 433:

In the so-called batch rinsing is in the container a Spülflüssigkeitsbad filled, the strand of goods is in Circulated offset, and after a predetermined number of Strangum circulations the flushing agent is drained again. This results in a mixture of dirt laden Treatment liquor on the product with the rinsing liquid in the rinsing liquid bath. After a few bath changes the desired wash result is achieved.

Another procedure involves rinsing between two different levels of rinsing liquid in the container. In this case, the circulation movement of the goods strand Do not pour through while flushing and draining the treatment liquid interrupted. Instead, the rinsing liquid is circulated by a circulation pump, usually the liquor pump, during the treatment period circulated, with appropriate control the rinsing liquid inlet into the container and the Rinse fluid drain from the container in the container a Spülflüssigkeitsniveau is maintained, the between an upper and a lower level (the minimum level for proper operation of the circulation pump) commutes. Of the Dishwashing success is similar to batch flushing Determining the dirt load of the flushing rinsing liquid determine.

A third method is finally rinsing in the overflow. It is in circulating strand of goods in the container contained dirt laden treatment liquor continuous rinsing liquid, usually water, supplied, while the excess is diluted by the rinsing fluid Treatment liquor on a through an overflow pipe certain level is continuously lowered. The washing success results here by a continuous dilution the treatment bath; he can by appropriate Monitoring of the overflow over the overflow line, in increasing extent diluted treatment liquor determined become.

Of these rinse procedures, batch rinse and rinsing between two different levels in terms of rinse fluid consumption, i. usually the water consumption, most efficient. Due to the principle is the rinse fluid consumption during overflow rinse highest, so this flushing procedure inefficient in terms of rinse fluid consumption is.

The water consumption of a dyeing machine is in many Industrialized countries an essential criterion for economic efficiency a wet refining process. The economy but also u.a. from the achieve the flushing time depending on the given flushing success affected. Relatively long flush times result accordingly long total treatment times and restrict so that the achievable on the machine throughput.

As in a nozzle treatment machine of this kind also when rinsing the drive of endless goods strand on hydraulic Paths through which the transport nozzle acting Fleet current takes place, is independent of the used Flushing the amount of flushing fluid required per unit of time strong of the for the drive of the goods strand required amount of liquid. It will in other words a considerable amount of rinsing liquid, i.e. usually rinsing water, easy to drive the flow of goods needed. It has already been tried (see Melliland Textile reports a.O.) during the flushing process on the drive the goods strand through the circulated by the circulation pump Fleet to abandon and the strand of goods thereby To drive that only fresh rinse water than Transport medium is introduced into the JET nozzle around with this both the rinsing and the material transport too accomplish, but is such a procedure because high rinse water needs and poor fluid exchange between the fresh air flowing through the nozzle Rinse water and carried by the strand of goods dirt-laden treatment liquor very uneconomical.

The object of the invention is therefore a rinsing process for textile material on JET treatment machines to create that allows the rinse fluid consumption, i.e. usually the rinse water consumption and the Carrying out the rinsing required time low and according to the existing one Conditions so that the production costs for the entire, requiring a rinse Wet finishing process can be minimized.

To solve this problem, the inventive Method on the features of claim 1.

The invention is based on the recognition that at JET treatment machines according to the aerodynamic principle the transport of the endless stock of goods from the treatment fleet is independent because of the strand of goods through the Actuation of the venturi transport nozzle with a gaseous Transport medium, if necessary, supported by a foreign driven reel takes place and therefore new possibilities for rinsing the goods revealed.

In the new method for rinsing strand-like Textile is accordingly proceeded so that the textile in the form of an endless string of goods by means of a Venturi transport nozzle in a closed container through a gaseous transport medium is circulated. The textile is the action of a rinsing liquid exposed, such that the rinsing with steadily flowing Rinsing fluid is made. Here are the Rinse liquid application per unit time by and / or the Goods flow speed depending on goods-specific Data of the textile material, of machine-specific Data and procedural data appropriate controlled. The emerging from the transport nozzle Dirty rinse liquid is removed from the container.

In practice this means that e.g. fresh rinse water directly from a water pipe, if necessary. Via a pump and a heat exchanger in the goods flow path before and / or in the transport nozzle and / or after this in the described Manner is applied to the goods. The expiring Dirty rinse water is then drained immediately. This will achieve that compared to the ratios in the above-mentioned hydraulic JET treatment machine a significantly reduced amount of flushing water is needed while simultaneously shortening the purge time can be.

This opens up the possibility of rinsing liquid consumption per unit time and the rinsing time, depending of predetermined criteria, to optimize. In a special advantageous embodiment of the new method can this happened in the way that made goods specific Data of the textile goods, for example weight, substrate and presentation of the product line, from construction-related data the transport nozzle, such as nozzle diameter, nozzle length, etc. and treatment-specific data, such as orbital velocity of the product strand and the like, a computing model determining the rinsing process and its success. The control of the rinsing liquid throughput per Time unit through the transport nozzle and the goods strand circulation speed done by a computer depending from this given calculation model.

The calculation model can be done during the flushing process recorded data will be updated. Besides that, can be the computing model by simple experiments with the in the practical flushing operation obtained data compare and oaks.

In practice, the success of a rinse will either with dyeing feeling or by simple by hand tests carried out. These tests may e.g. in the Wringing out a strand and catching it from dripping Water to determine the residual color. Another possibility is e.g. the measurement of the pH or the electrical conductivity of the dirt laden expiring rinse liquid. These tests are in the Usually performed directly on the machine by either Fleet removed or the machine is stopped. In the finished wet treated (finished) goods will be then mostly consistently standardized quality controls carried out (rub fastness, wash fastness, perspiration fastness, etc.), which spread worldwide and their results as well are comparable to each other.

The inventive method in which a direct Rinsing the product with rinsing liquid takes place, can now so be designed that the success of the flushing process is ongoing or monitored on-line at intervals. The thus determined, characteristic for the respective dishwashing success Data can be in the controller and in particular into the calculation model, to the rinsing process automatically to change or to determine the end of the rinsing process. Changes in the rinsing process can, for example, such happen that the rinse liquid order on the goods strand at the beginning of the rinsing process, i. at the first Circulations of the goods strand differently, in particular higher as towards the end of the flushing process.

• Sensoren zur pH-Wert Messung der schmutzbeladenen Spülflüssigkeit für das Ausspülen von Säuren und Laugen,
• Sensoren zur Messung des elektrischen Leitwerts der schmutzbeladenen Spülflüssigkeit für das Ausspülen von Salzen,
• Trübungssensoren für die Messung der Restfarbigkeit in der schmutzbeladenen Spülflüssigkeit.

Since in the new rinsing process a direct rinsing of the goods takes place in the rinsing liquid flowing through the container, the dirt load of the rinsing liquid loaded with dirt is a measure of the rinsing effect achieved. For example, the following sensors can be used to measure this dirt load:

• Sensors for measuring the pH value of dirt-loaded rinsing liquid for rinsing out acids and alkalis,
• Sensors for measuring the electrical conductance of the dirt-laden rinsing liquid for rinsing salts,
• Turbidity sensors for the measurement of residual color in the dirt-loaded rinse liquid.

The measurement of the dirt load can be done in the container running rinse water and / or directly on the strand of goods respectively.

• ein vorgegebener absoluter Messwert wenigstens einer für die Schmutzlast des schmutzbeladenen Spülflüssigkeit kennzeichnenden Größe, bspw. deren Trübung, elektrischer Leitwert, pH-Wert und dergleichen,
• ein vorgegebenes Verhältnis zwischen einem Anfangs- und einem Endwert wenigstens einer für die Schmutzlast der schmutzbeladenen Flüssigkeit kennzeichnenden Größe
• die zeitliche Änderung einer für die Schmutzlast kennzeichnenden Größe der schmutzbeladenen Spülflüssigkeit.
• Durch die erste zeitliche Ableitung des Messwerts dieser Größe wird die Frage beantwortet um wieviel sich der Messwert pro gegebene Zeiteinheit verändert. Nachdem alle Spülvorgänge, graphisch gesehen, in einer sich abflachenden Kurve enden, die anzeigt, dass sich die Schmutzpartikelkonzentration mit fortschreitender Spülzeit kaum mehr ändert, kann auch die erste Ableitung des erwähnten Messwerts als Kriterium für das Ende der Spülzeit dienen.

To determine the end of the purge time, the following may be used, among others, the following criteria measured by corresponding sensors and / or calculated by the computer:

• a predetermined absolute measured value of at least one variable characterizing the dirt load of the dirt-laden rinsing liquid, for example its turbidity, electrical conductance, pH value and the like,
• a predetermined ratio between an initial and a final value of at least one of the dirt load of the dirt-laden liquid characterizing size
• the change with time of a size of the dirt-loaded rinsing liquid that characterizes the dirt load.
• By the first temporal derivative of the measured value of this variable, the question is answered by how much the measured value changes per given time unit. After all rinses, graphically, terminate in a flattening curve indicating that the soil particle concentration hardly changes any more as the rinse time progresses, the first derivative of the noted measurement may also serve as the end rinse time criterion.

The combination of theoretically calculated values and practically measured values in the mentioned calculation model allows a further optimization of the rinsing process. It is conceivable, for example, that at the beginning of the rinsing process, where with high volumes of flushing fluid quickly cause a large concentration drop is reached, the purge time is optimized. Towards the end of the flushing process when the concentration differences in the dirt-laden effluent flushing liquid from goods circulation to circulation of goods no longer special are large, it is advantageous with a smaller amount of flushing liquid but with a little more time to work. The result is in any case a flushing process, in terms of both the amount of flushing fluid required as well as with regard to the required rinsing time is optimized.

This optimization is in the practical wet treatment plant, i.e. in the dyeing of great economic Importance. For example, work in certain industrialized countries the dye works usually with relatively less Production and high water costs while in other countries a high production and very low water costs given are. There are also areas where the process water is assigned to the dye works, and thus an increase in production only possible if with the constant allocated amount of water a higher production and thus a higher yield can be achieved.

The method according to the invention makes it possible to know the data required for the flushing process the flushing process to optimize. In particular, using the computing model The control itself can control the water consumption or the required production time depending on the existing production conditions, such as water price, Calculate production volume and the like. Of the Operator or programmer of wet treatment machine the control only needs to know if the flushing process in terms of water consumption or terms the production time should be optimized.

Further embodiments of the method according to the invention are the subject of dependent claims. They arise also from the following description of an embodiment of the inventive method based on the The following drawing illustrates.

The high temperature shown schematically in Figure 1 (HT) -Stückfärbemaschine has a pressure-resistant, cylindrical Container 1, in which a closable by a cover 2 Operating opening 3 leads, through which a Strand of goods 4 can be introduced. The product strand 4 is via a driven-third reel 5 in a Venturi transport nozzle 6 introduced, followed by a Abtafler 7 connects. The Abtafler 7 sets the from the transport nozzle. 6 emerging strand of goods 4 tabulated in a memory. 8 from, from the endless strand of goods through the reel 5 again is pulled out. The reel 5 and the transport nozzle 6 are housed in housing parts 9, with the container 1 are connected liquid-tight. The product strand 4 was after insertion through the operating opening 3 at its ends connected to an endless loop of goods.

The transport nozzle 6 is provided with a gaseous transport medium flow charged, which the continuous strand of goods 4 in a direction indicated by an arrow 10 circulating sense circulated. The transport medium is present Fall air or a vapor-air mixture passing through a Blower 11 and a suction line 12 sucked out of the container 1 and via a pressure line 13 in the transport nozzle. 6 is transported.

On the container 1, a liquor outlet 14 is arranged below, which contains a Fleettensieb 15 and with a Suction line 16 of a liquor circulating pump 17 is connected, whose pressure line 18 includes a heat exchanger 19 and via a control valve 20 opens into the transport nozzle 6. The Fleet circulation pump 17 allows sucked from the container 1 Fleet on the transport nozzle 6 and the container. 1 to circulate. Parallel to the heat exchanger 19 and the liquor circulating pump is a bypass line 22, the one Includes shut-off valve 23 and the liquor drain 14 with the Pressure line 21 connects.

Finally, an additive container 24 is provided, in aqueous solution, emulsion or dispersion contains a chemical additive that via an additive pump 25 and a connecting line 26 in the suction line 16 of the liquor circulating pump 17 are fed can.

The extent described, after the aerodynamic Principle working piece dyeing machine is known per se. If necessary in the course of a treatment process If the product strand 4 is to be rinsed, the procedure is as follows:

A drain valve 27 of the liquor drain 14 and a Inlet valve 28 in the suction line 16 of the liquor circulating pump 17 are opened. Flows via the inlet valve 28 Rinse water in the suction line 16, as by a Arrow 29 is indicated. The incoming rinse water can if necessary from the additional container 24 with the flushing facilitating or supporting additives and in the heat exchanger 19 to an appropriate Rinse temperature are brought before it into the transport nozzle 6 occurs.

The fan 11 is turned on and promotes a via the lines 12, 13, the transport nozzle 6 and the container 1 circulating transport air flow, the goods strand 4 in the direction of rotation 10 drives.

The entering into the transport nozzle 6 rinse water is in the transport nozzle 6 on the product strand forming Ware applied. The from the reel 5 from the memory. 8 withdrawn strand of goods 4 is entering the transport nozzle 6 soaked with dirt-laden liquor passing through the product strand is introduced into the transport nozzle 6. In the transport nozzle 6 is mixed with the Dirt-laden liquor, which passes over the rope in the Transport nozzle passes and by injection over the Pressure line 21 supplied flushing water.

The emerging from the transport nozzle 6, dirt laden Rinse water is collected in the container 1 and then via the liquor drain 14 and the drain valve 27th discharged, as indicated by an arrow 30. The suction line 15 is closed by a check valve 31 against the Suction side of the liquor circulating pump 17 shut off.

With increasing number of revolutions of the fabric strand 4 the dirt-laden fleet contained in it will be increasing Measured by the injected via the transport nozzle 6 Rinsing water thinned, until finally the respectively desired Dishwasher success occurred. The entrance of this Dishwashing success can be determined on-line by sensor means 32 be that of the effluent from the container 1 dirt-laden rinse water are flowed through. The sensor means 32 monitor, for example, the pH, the electrical Conductance and the turbidity of the effluent rinse water and give appropriate, characteristic for these sizes electrical Signals as data in a computer 33 of the controller one.

When the desired rinsing effect is achieved, the supply becomes again turned off and the piece dyeing machine is for set up the next wet treatment step.

During the rinsing process, the goods strand is through the from the fan 11 promoted air flow independent of the driven injected flushing water quantity. By appropriate Control of the fan 11, the rotational speed of the strand 4 are constantly changed, while the Control valve 20 allows the injected per unit time Rinse water amount, controlled by a computer 33 to change.

Alternatively or additionally, the rotational speed of the strand 4 also be changed by that the computer 33 a downstream of the fan 11 in the Pressure line 13 lying throttle 34 controls. The injected Rinse water quantity can also be controlled by a control be changed to the circulation pump 17, as shown in Figure 1 is indicated.

The introduced with the product strand 4 in the transport nozzle 6 Amount of dirt laden fleet essentially depends from factors such as weight, substrate and weight Presentation of the product strand 4. From this it is calculated how much Liters of liquid can absorb the strand of goods. The Amount of actually absorbed liquid in the ratio set to the product weight results in the so-called "Pick up". It also depends on the speed of the goods strand 4. The with the strand of goods in the Transport nozzle 6 introduced dirt-laden fleet depends directly on the speed of rotation of the strand of goods from.

Based on these findings can be a computing model develop that reflects the success of the flushing. This calculation model can be tested by using the practical Ratios are compared and calibrated. Figure 2 shows the result of such comparison experiments between the theoretical Invoice and the actual measured values.

Plotted is the dirt concentration in grams per Liter in the drained from the liquor drain 14 dirt laden Rinse water depending on the number of cycles of the strand 4. The two curves show that the concentration during the first rounds of the product strand falls steeply and with increasing number of Strange cycles asymptotically a minimum residual value approaches. The match between bill and actual Measurement is clearly good.

With the computer model thus obtained, the parameters optimized for the flushing process in simulation calculations. The result of these calculations is for one embodiment illustrated in Figures 3 to 5.

The embodiment underlying Figures 3 to 5 applies to a cotton knit fabric with an average grammage of 250gr / m ² and with the following parameters: Pick up (%) 330 Loading storage (Kg) 200 Initial dirt load (gr / ltr) 35 Residual dirt load at end of flushing time (gr / ltr) 3

This results in the following values for the flushing time in minutes and for the flushing water consumption in liters per kilogram, which are graphically illustrated in the graphs of Figures 3, 4, which represent the percentage change from a particular machine setting.

These values and the graphs of Figure 3, 4 show that the rinsing time by changing rinse water supply can be shortened significantly and that on the other hand the Rinse water consumption reduced by lengthening the flushing times can be. Reduced with underloading of the machine By the way, automatically the rinse time.

From Figure 5 it can be seen that with decreasing Rinse time the rinse water consumption increases to a certain to achieve predetermined rinsing effect. In the first (left) third drops the required rinsing time very strong. In the last (right) third of the rinse water consumption increases very strong, although the rinsing time drops only slightly. The optimal operating range is therefore in the middle Third, in which at almost constant rinse water consumption the rinsing time can be significantly reduced.

The values given in Tables 1, 2 show that by varying the amount of flushing water per unit time (Injection amount) and the goods running speed as they indicated by the dark fields of the table is, e.g. a time saving of 75% can be achieved while at the same time the required amount of flushing water only to 38% increases.

The illustrated embodiment shows that at low flushing water costs at the expense of increased flushing water consumption the quantity of goods produced and thus the Yield can be increased significantly, because the rinsing time is shortened while at high Spülwasserkosten by Extension of the rinsing time and, therefore, by use additional machine capacity of the cost can be significantly reduced.

In the above description has been generally of Spoken "flushing liquid" which, as pointed out, usually rinse water is. Basically, though also other rinsing liquids, including those of organic nature be used when doing so in terms of being flushed Textile is useful.

In the embodiment described above the rinsing liquid is injected into the transport nozzle 6 (Figure 1) and thus applied to the fabric strand 4. alternative or additionally, however, the new flushing process can be carried out such that the rinsing liquid in Warenstranglaufweg and / or after the transport nozzle 6 on the product strand 4 is applied. This is in FIG. 1 illustrated schematically by way of example. In the housing 9 opens above the reel 5 a example. From the pressure line 21 outgoing Spülflüssigkeitsleitung 34, in the one Control valve 35 is controlled by the computer 33 can be. This ensures that the in the transport nozzle 6 entering strand already with rinsing liquid loaded.

The line 34 does not necessarily need to be in the area to open above the reel 5. Depending on the particular Given conditions, the mouth of the line 34 somewhere between the reel and the nozzle gap of the Venturi transport nozzle 6 lie. In addition, embodiments are also conceivable in which the mouth of the conduit 34 in which between the Memory 8 and the reel 5 lying (vertical) Laufwegsbereich the product strand 4 is and rinsing liquid already applied to the fabric strand 4 before this the reel reaches 5. In Fig. 1, this variant is with a dash-dotted line indicated that a pressure line 34a, in which a control valve 35a is located, which can also be controlled by the computer 33.

In addition, the rinse liquid order on the fabric strand 4 also one in the goods flow way behind the Transport nozzle 6 opening pressure line 36 may be provided the example. From the pressure line 21 branches off and a control valve 37, which is controlled by the computer 33 becomes. In this way it is possible behind the transport nozzle Rinse liquid either alternatively or additionally on the strand 4 give up.

The running of the product strand 4 dirt laden Rinsing liquid is collected in the container 1 and over the sump and the drain valve 27 is drained. alternative But it can also be done so that the dirt laden Rinsing liquid discharged from the container in batches is, i. the rinse liquid is in the container collected for later reuse become.

Finally, it should be mentioned that the entry of the Washing success detecting sensor means 32 not necessarily must be located behind the drain valve 27, to monitor the draining flushed rinse liquid. The measurement or determination for the dirt load Characteristic data can also directly on the strand of goods 4 done.
