Definitions
- the invention relates to a method for dyeing a textile fabric with the aid of a dyeing pad, in which a predetermined color distribution of the dry fabric sheet is set by specifying a squeezing force distribution of the foulard. It also relates to an apparatus for performing the method.
- the fabric web coming out of the immersion trough of the foulard containing a dye liquor should be squeezed so that the distribution of the remaining liquor or moisture - the so-called initial moisture content determining the further process - is such that a predetermined color distribution the dried fabric is achieved.
- the aim is to ensure that the coloring of the edges of the fabric with one another and with that in the middle of the fabric is the same.
- Moisture measuring devices are known for determining the moisture, which are assigned to the wet fabric web coming from the foulard near the edges and near the center.
- test runs of the dyeing system are therefore first carried out in order to be able to adjust the squeezing force distribution of the foulard - not necessarily to the same initial moisture content but - to a predetermined color drop or the same in all cases with plain dyeing. Since the transport route from the foulard entrance to the exit of the entire dyeing system can be up to 100 m and more, and since further fabric sections are required for setting and assessing the final dyeing, a test run can result in many meters of spoiled goods or Goods of poor quality cost.
- the invention has for its object to detect incorrect colorations due to different behavior of the treated goods during dyeing and to intervene immediately without significant loss of incorrectly colored Met rage corrective action and possibly cancel the coloring early enough.
- the solution according to the invention consists in regulating the squeeze force distribution of the foulard as a function of the measured color distribution of the fabric web still having the initial moisture at the foulard exit becomes.
- the color measurement of the fabric at the padding exit means that any deviations in the color distribution from the target value are practically immediate be detected after leaving the foulard, so that only a few meters, for example, to set the squeeze force distribution required for the predetermined color distribution. B. 2 m, fabric are required. So there is practically no loss, even if the quality of a batch of fabric differs in individual sections, because then after a few meters or in 1 to 2 seconds the squeeze force distribution required for the predetermined color distribution must be set.
- the moisture measurement previously carried out for this purpose per se could be omitted.
- a moisture measuring device For the moisture measurement, it is preferably provided to arrange a moisture measuring device over the longitudinal web strip, in particular over the middle of the web, on which the color measurement is also carried out.
- an absolute measurement of the color can also be provided, particularly in this case. If necessary, the absolute value of the color, of the web of material still having the initial moisture, is measured for a specific regulated web of moisture. Such a target value determination is worthwhile if large batches have to be colored repeatedly. It is then also possible to measure and regulate the color depth or the color selection immediately after the fabric web has left the foulard.
- the invention is particularly important in solid dyeing because it is important here to exclude even the smallest color differences between the edge and center of the fabric and between the edges of the fabric.
- the dyeing of the fabric edges is compared with the color of the fabric center in uni-dyeing, and the color differences thus determined are automatically eliminated by controlling the squeezing force distribution.
- the squeeze force distribution of the foulard automatically it is set that the differences become zero.
- the color distribution of the still wet web of material at the paddle exit is preferably determined with the aid of a color measuring device which is in control connection with the paddle, and if the predetermined color distribution deviates, a correction signal is automatically sent via the computer to the paddle or its squeeze.
- the automatic system with a computer etc. gives the advantageous possibility of automatically registering incorrectly colored fabric web sections which are only a few meters long. Faults in a fabric panel therefore do not have to be laboriously determined at the viewing table, they can instead be taken from a log attached to the finished goods by location and type and in particular marked at the edge of the fabric panel.
- the fabric web 1 is mechanically dewatered to a moisture value which is referred to as initial moisture for the following treatment.
- the web of material runs past the squeezer 6 past a moisture measuring device 9 and a color measuring device 10.
- the moisture measuring device g and the color measuring device 10 can also be arranged next to one another or in the reverse order.
- the fabric web 1 passes via a guide roller 11 to the wet, dwell, drying and, if appropriate, fixing systems connected in the direction of the arrow 12, not shown.
- the squeeze force distribution of the squeeze 6 is regulated as a function of the color distribution of the fabric web 1 still having the initial moisture, determined with the color measuring device 10.
- a control connection 13 with a computer 14 is provided between the color measuring device 10 and the pinch 6. If there is a deviation from a predetermined color distribution of the dry The color measuring device 10 automatically sends a correction signal to the pinch 6 via the control connection 13 and the computer 14.
- the squeezer 6 is selected so that it can deliver a squeeze profile that can be adapted to any customary coloring task.
- a suitable squeeze is described, for example, in European Patent No. 49 798 and in US Patent No. 44 40 012.
- the device according to the exemplary embodiment also contains a moisture measuring device 9, which should also be in control connection 13 with the pinch via the computer 14.
- the measurement of the web moisture is carried out, for example, in the center 15 of the web, preferably on the same track as the color measurement.
- the moisture measurement is generally used to set the initial moisture to an experimentally specified value that ensures a certain depth of color.
- the predetermined value is constantly controlled by the computer 14 and adapted to the corresponding color depth.
- the color depth and a difference in the measurement results for the left edge 16 and the right edge 17 relative to the center 15 of the fabric web 1 are measured in the color measurement, that is to say the measurement results at the fabric web edges 16 and 17 are compared with the measurement result of the fabric web center 15 .
- the (only) color measuring device 10 is arranged such that it can be moved automatically on a rail 18 in the transverse direction of the fabric web 1.
- several, preferably three such devices or measuring heads can be used in a fixed position. The preferred measuring positions are indicated in the drawing of FIG. 2 with solid or dashed lines.
- a corresponding signal is sent to the computer 14 and from there to the squeezer 6.
- the duration and type of deviation as well as the affected piece of fabric can be registered via the computer 14 and printed out in a protocol to be provided with the finished goods.
- an absolute measurement of the color can also be provided if the color strength for a specific humidity regulated by the moisture measurement device 9 is predetermined by a setpoint value to be determined on the color measurement device 10.

Description
Die Erfindung betrifft ein Verfahren zum Färben einer textilen Stoffbahn mit Hilfe eines Färbefoulards, bei dem eine vorbestimmte Farbverteilung der trockenen Stoffbahn durch Vorgabe einer Quetschkraftverteilung des Foulards eingestellt wird. Sie betrifft ferner eine Vorrichtung zum Durchführen des Verfahrens.The invention relates to a method for dyeing a textile fabric with the aid of a dyeing pad, in which a predetermined color distribution of the dry fabric sheet is set by specifying a squeezing force distribution of the foulard. It also relates to an apparatus for performing the method.
Beim Färben mit einem Färbefoulard soll die aus dem eine Farbflotte enthaltenden Tauchtrog des Foulards kommende Stoffbahn so abgequetscht werden, daß die Verteilung der verbleibenden Flotte bzw. Feuchte - die sogenannte, die Farbtiefe bestimmende Anfangsfeuchte für den weiteren Prozeß - so ist, daß eine vorbestimmte Farbverteilung der getrockneten Stoffbahn erzielt wird. Beim Uni-Färben soll auf diese Weise erreicht werden, daß die Färbung der Stoffbahnränder untereinander und mit derjenigen in der Stoffbahnmitte gleich ist. Zum Ermitteln der Feuchte sind Feuchtemeßgeräte bekannt, die der aus dem Foulard kommenden feuchten Stoffbahn in der Nahe der Kanten und in der Nähe der Mitte zugeordnet werden.When dyeing with a dyeing pad, the fabric web coming out of the immersion trough of the foulard containing a dye liquor should be squeezed so that the distribution of the remaining liquor or moisture - the so-called initial moisture content determining the further process - is such that a predetermined color distribution the dried fabric is achieved. In the case of uni dyeing, the aim is to ensure that the coloring of the edges of the fabric with one another and with that in the middle of the fabric is the same. Moisture measuring devices are known for determining the moisture, which are assigned to the wet fabric web coming from the foulard near the edges and near the center.
Es ist bereits Praxis, den Foulard in Abhängigkeit von den Meßergebnissen der Feuchtemeßgeräte zu steuern. Ein derartiges Regelverfahren wird durch das Dokument DE-A-2 646 897 (& FR-A-2 367 851) offenbart. Es hat sich aber gezeigt, daß trotz gleicher Flottenaufnahme bzw. Feuchte am Ausgang des Foulards unterschiedliche Färbungen der fertiggestellten Ware auftreten, das kann von entsprechenden Unterschieden der Saugfähigkeit, der Dicke, der Vorbehandlung, insbesondere Weißgradschwankungen nach dem Bleichen, und dergleichen der zu färbenden Stoffbahn herrühren. Nach dem Stand der Technik führt man daher zunächst Probeläufe der Färbeanlage durch, um die Quetschkraftverteilung des Foulards - nicht unbedingt auf gleiche Anfangsfeuchte sondern - auf einen vorbestimmten bzw. bei Uni-Färbung überall gleichen Farbausfall einstellen zu können. Da der Transportweg vom Foulard-Eingang bis zum Ausgang der gesamten Färbeanlage bis zu 100 m und mehr betragen kann und da zum Einstellen sowie Beurteilen der endgültigen Färbung weitere Stoffbahnabschnitte erforderlich sind, kann so ein Probelauf viele Meter verdorbener Ware oder Ware minderer Qualität kosten.It is already common practice to control the foulard as a function of the measurement results of the moisture measuring devices. Such a control method is disclosed by document DE-A-2 646 897 (& FR-A-2 367 851). It has been shown, however, that despite the same liquor absorption or moisture at the exit of the foulard, different colors of the finished goods occur, which can result from corresponding differences in the absorbency, the thickness, the pretreatment, in particular fluctuations in whiteness after bleaching, and the like of the fabric to be dyed come from. According to the prior art, test runs of the dyeing system are therefore first carried out in order to be able to adjust the squeezing force distribution of the foulard - not necessarily to the same initial moisture content but - to a predetermined color drop or the same in all cases with plain dyeing. Since the transport route from the foulard entrance to the exit of the entire dyeing system can be up to 100 m and more, and since further fabric sections are required for setting and assessing the final dyeing, a test run can result in many meters of spoiled goods or Goods of poor quality cost.
Weiterhin kommen trotz Probelauf Fehlfärbungen vor. Die Qualität einer überall gleich zu färbenden Charge kann nämlich, z. B. weil einzelne aneinander genähte Abschnitte von verschiedenen Webmaschinen kommen, so variieren, daß die durch den Probelauf ermittelte Foulardeinstellung für den einen oder anderen Abschnitt der Stoffbahncharge nicht paßt. Bei derzeit im Einsatz befindlichen Maschinen ist dann mit entsprechenden Verlusten zu rechnen.In spite of the test run, there are still incorrect stains. The quality of a batch to be colored the same everywhere can be, for. B. because individual sewn sections come from different weaving machines, vary so that the foulard setting determined by the test run does not fit for one or the other section of the fabric batch. In the case of machines currently in use, corresponding losses can then be expected.
Schließlich fallen geringe Farbunterschiede einzelner Abschnitte einer Stoffbahncharge beim Färben nicht immer auf, so daß es häufig erforderlich ist, die fertig gefärbte Stoffbahn auf einem Schautisch zu prüfen und zu sortieren, um etwaige Fehler festzustellen und zu registrieren bzw. an der Stoffbahn zu markieren.Finally, slight color differences in individual sections of a batch of fabric during dyeing are not always noticeable, so that it is often necessary to check and sort the finished fabric on a display table in order to identify and register any errors or to mark them on the fabric.
Der Erfindung liegt die Aufgabe zugrunde, Fehlfärbungen infolge unterschiedlichen Verhaltens der behandelten Ware beim Färben frühzeitig zu erkennen und sofort ohne nennenswerte Verluste an fehlgefärbter Met rage korrigierend einzugreifen und gegebenenfalls die Färbung frühzeitig genug abzubrechen.The invention has for its object to detect incorrect colorations due to different behavior of the treated goods during dyeing and to intervene immediately without significant loss of incorrectly colored Met rage corrective action and possibly cancel the coloring early enough.
Für das Verfahren eingangs genannter Art, bei dem eine vorbestimmte Farbverteilung der trockenen Stoffbahn durch Vorgabe einer Quetschkraftverteilung des Foulards eingestellt wird, besteht die erfindungsgemäße Lösung darin, daß die Quetschkraftverteilung des Foulards in Abhängigkeit von der gemessenen Farbverteilung der noch die Anfangsfeuchte am Foulardausgang aufweisenden Stoffbahn geregelt wird.For the method of the type mentioned above, in which a predetermined color distribution of the dry fabric is set by specifying a squeeze force distribution of the foulard, the solution according to the invention consists in regulating the squeeze force distribution of the foulard as a function of the measured color distribution of the fabric web still having the initial moisture at the foulard exit becomes.
Durch die Farbmessung der Stoffbahn am Foulardausgang wird erreicht, daß eventuelle Abweichungen der Farbverteilung vom Sollwert praktisch sofort nach dem Verlassen des Foulards erfaßt werden, so daß zum Einstellen der für die vorbestimmte Farbverteilung erforderlichen Quetschkraftverteilung nur wenige Meter, z. B. 2 m, Stoffbahn erforderlich sind. Es gibt also praktisch keinen Verlust, das gilt selbst für den Fall, daß sich die Qualität einer Stoffbahncharge in einzelnen Abschnitten unterscheidet, weil dann jeweils nach wenigen Metern bzw. in 1 bis 2 Sekunden die für die vorbestimmte Farbverteilung jeweils erforderliche Quetschkraftverteilung einzustellen ist.The color measurement of the fabric at the padding exit means that any deviations in the color distribution from the target value are practically immediate be detected after leaving the foulard, so that only a few meters, for example, to set the squeeze force distribution required for the predetermined color distribution. B. 2 m, fabric are required. So there is practically no loss, even if the quality of a batch of fabric differs in individual sections, because then after a few meters or in 1 to 2 seconds the squeeze force distribution required for the predetermined color distribution must be set.
Bei der erfindungsgemäßen Steuerung bzw. Regelung der Quetschkraftverteilung des Foulards aufgrund einer Farbmessung könnte die bisher zu diesem Zweck ausgeführte Feuchtemessung an sich entfallen. In der Praxis kann es trotzdem vorteilhaft sein, die Feuchte zu messen, um die Flottenaufnahme einer Stoffbahn zu kontrollieren, insbesondere dann, wenn beim Farbmessen nur Relativwerte, z. B. zwischen der Farbe von Stoffbahnmitte und Stoffbahnrand, ermittelt werden. Gemäß weiterer Erfindung kann es daher günstig sein, wenn der Betrag der Anfangsfeuchte auf einen vorgegebenen Wert eingestellt und konstant geregelt wird. Der vorgegebene Wert bestimmt dann beispielsweise den Farbton der fertig gefärbten oder mit Farbstoff getrockneten sowie gegebenenfalls farbfixierten Stoffbahn.In the control or regulation of the squeezing force distribution of the foulard based on a color measurement according to the invention, the moisture measurement previously carried out for this purpose per se could be omitted. In practice, it can nevertheless be advantageous to measure the moisture in order to control the absorption of the liquor into a fabric web, in particular if only relative values, e.g. B. between the color of the center of the fabric and the edge of the fabric. According to a further invention, it can therefore be favorable if the amount of the initial moisture is set to a predetermined value and regulated constantly. The specified value then determines, for example, the color of the fabric web that has been completely dyed or dried with dye and, if appropriate, color-fixed.
Vorzugsweise wird für die Feuchtemessung vorgesehen, ein Feuchtemeßgerät über den Stoffbahnlängsstreifen, insbesondere über der Stoffbahnmitte, anzuordnen, an dem auch die Farbmessung vorgenommen wird. Gemäß weiterer Erfindung kann besonders in diesem Fall auch eine Absolutmessung der Farbe vorgesehen werden. Gegebenenfalls wird der absolute Wert der Farbe, der noch die Anfangsfeuchte aufweisenden Stoffbahn, für eine bestimmte eingeregelte Stoffbahnfeuchte gemessen. Eine solche Sollwertermittlung ist lohnend, wenn große Chargen wiederholt zu färben sind. Es läßt sich dann auch die Farbtiefe bzw. die Farbauswahl schon unmittelbar nach Austritt der Stoffbahn aus dem Foulard messen und regeln.For the moisture measurement, it is preferably provided to arrange a moisture measuring device over the longitudinal web strip, in particular over the middle of the web, on which the color measurement is also carried out. According to a further invention, an absolute measurement of the color can also be provided, particularly in this case. If necessary, the absolute value of the color, of the web of material still having the initial moisture, is measured for a specific regulated web of moisture. Such a target value determination is worthwhile if large batches have to be colored repeatedly. It is then also possible to measure and regulate the color depth or the color selection immediately after the fabric web has left the foulard.
Besondere Bedeutung hat die Erfindung beim Uni-Färben, weil es hierbei darauf ankommt, auch kleinste Farbunterschiede zwischen Stoffbahnrand und -mitte sowie zwischen den Stoffbahnrändern untereinander auszuschließen. Gemäß weiterer Erfindung wird beim Uni-Färben die Färbe der Stoffbahnkanten mit der Farbe der Stoffbahnmitte verglichen, und die so ermittelten Farbdifferenzen werden automatisch durch Steuerung der Quetschkraftverteilung eliminiert.The invention is particularly important in solid dyeing because it is important here to exclude even the smallest color differences between the edge and center of the fabric and between the edges of the fabric. According to a further invention, the dyeing of the fabric edges is compared with the color of the fabric center in uni-dyeing, and the color differences thus determined are automatically eliminated by controlling the squeezing force distribution.
Wesentlich im Rahmen der Erfindung ist die Automatik. Die Bedienungsperson, die mit dem bloßen Auge auch schädliche Farbunterschiede an der noch feuchten Stoffbahn ohnehin im allgemeinen nicht erkennen kann, braucht also nicht selbst in den Mechanismus einzugreifen, weil bei Farbtiefendifferenzen sowie bei Farbdifferenzen zwischen Rand und Mitte der Stoffbahn die Quetschkraftverteilung des Foulards automatisch so eingestellt wird, daß die Differenzen zu Null werden. Hierzu wird vorzugsweise die Farbverteilung der noch feuchten Stoffbahn am Foulardausgang mit Hilfe eines über einen Rechner in Steuerverbindung mit dem Foulard stehenden Farbmeßgeräts ermittelt, und bei Abweichung von der vorbestimmten Farbverteilung wird automatisch ein Korrektursignal über den Rechner an den Foulard bzw dessen Quetsche gegeben. In weiterer Ausgestaltung der Erfindung ergibt sich durch die Automatik mit Rechner usw. die vorteilhafte Möglichkeit, während der Regel zeit fehl gefärbte Stoffbahnabschnitte, die nur ein paar Meter betragen, automatisch zu registrieren. Fehler einer Stoffbahn brauchen also nicht am Schautisch mühsam ermittelt zu werden, sie können vielmehr einem der fertigen Ware beigefügten Protokoll nach Ort und Art entnommen und insbesondere bereits am Stoffbahnrand markiert werden.Automatic is essential in the context of the invention. The operator, who is generally not able to see harmful color differences on the still wet fabric anyway with the naked eye, does not need to intervene in the mechanism himself, because with color depth differences and color differences between the edge and center of the fabric the squeeze force distribution of the foulard automatically it is set that the differences become zero. For this purpose, the color distribution of the still wet web of material at the paddle exit is preferably determined with the aid of a color measuring device which is in control connection with the paddle, and if the predetermined color distribution deviates, a correction signal is automatically sent via the computer to the paddle or its squeeze. In a further embodiment of the invention, the automatic system with a computer etc. gives the advantageous possibility of automatically registering incorrectly colored fabric web sections which are only a few meters long. Faults in a fabric panel therefore do not have to be laboriously determined at the viewing table, they can instead be taken from a log attached to the finished goods by location and type and in particular marked at the edge of the fabric panel.

Nach Fig. 1 und 2 wird eine textile Stoffbahn 1, z. B. aus Webware, Maschenware oder ein Non-Wowen, über eine Leitwalze 2 und eine Tauchwalze 3 durch ein in einem Trog 4 befindliches Farbbad 5 geleitet. Nach dem Auftauchen aus dem Farbbad 5 gelangt die Stoffbahn 1 in eine insgesamt mit 6 bezeichnete Quetsche. In dem Quetschspalt 7 der beiden Walzen 8 der Quetsche 6 wird die Stoffbahn 1 bis auf einen Feuchtewert mechanisch entwässert, der für die folgende Behandlung als Anfangsfeuchte bezeichnet wird. Im Ausführungsbeispiel läuft die Stoffbahn nach der Quetsche 6 vorbei an einem Feuchtemeßgerät 9 und an einem Farbmeßgerät 10. Das Feuchtemeßgerät g und das Farbmeßgerät 10 können auch nebeneinander oder in umgekehrter Reihenfolge angeordnet werden. Im weiteren Verlauf gelangt die Stoffbahn 1 über eine Leitwalze 11 zu in Pfeilrichtung 12 nachgeschalteten, nicht gezeichneten, Naß-, Verweil-, Trocken- und gegebenenfalls Fixieranlagen.1 and 2, a textile fabric 1, z. B. from woven, knitted or non-woven fabric, passed through a
Wenn die Stoffbahn 1, z. B. eine Thermosolanlage durchlaufen hat, ist sie trocken. Sie soll dann eine vorbestimmte Farbverteilung besitzen. Diese Farbverteilung soll durch Quetschkraftverteilung im Quetschspalt 7 der beiden Quetschwalzen 8 eingestellt werden. Erfindungsgemäß wird die Quetschkraftverteilung der Quetsche 6 in Abhängigkeit von der mit dem Farbmeßgerät 10 ermittelten Farbverteilung der noch die Anfangsfeuchte aufweisenden Stoffbahn 1 geregelt. Dazu wird zwischen dem Farbmeßgerät 10 und der Quetsche 6 eine Steuerverbindung 13 mit einem Rechner 14 vorgesehen. Bei Abweichung von einer vorbestimmten Farbverteilung der trockenen Stoffbahn wird automatisch vom Farbmeßgerät 10 ein Korrektursignal über die Steuerverbindung 13 und den Rechner 14 an die Quetsche 6 gegeben.If the fabric 1, z. B. has passed a thermosol plant, it is dry. It should then have a predetermined color distribution. This color distribution should be set by squeezing force distribution in the
Die Quetsche 6 wird so ausgewählt, daß sie ein allen üblichen Färbeaufgaben beliebig anpaßbares Quetschprofil liefern kann. Eine geeignete Quetsche wird beispielsweise beschrieben in dem Europa-Patent Nr. 49 798 bzw. in dem US-Patent Nr. 44 40 012.The
Die Vorrichtung gemäß Ausführungsbeispiel enthält außer dem Farbmeßgerät 10 auch ein Feuchtemeßgerät 9, das ebenfalls über den Rechner 14 in Steuerverbindung 13 mit der Quetsche stehen soll. Die Messung der Stoffbahnfeuchte wird beispielsweise in der Stoffbahnmitte 15, vorzugsweise auf derselben Spur wie die Farbmessung vorgenommen. Die Feuchtemessung dient im allgemeinen dazu, die Anfangsfeuchte auf einen experimentell vorgegebenen Wert, der eine bestimmte Farbtiefe gewährleistet, einzustellen. Über den Rechner 14 wird der vorgegebene Wert konstant geregelt und der entsprechenden Farbtiefe angepaßt.In addition to the color measuring
Normalerweise wird bei der Farbmessung die Farbtiefe und eine Differenz der Meßergebnisse für den linken Rand 16 und den rechten Rand 17 gegenüber der Mitte 15 der Stoffbahn 1 gemessen, das heißt, die Meßergebnisse an den Stoffbahnrändern 16 und 17 werden mit dem Meßergebnis der Stoffbahnmitte 15 verglichen. Hierzu wird im Ausführungsbeispiel das (einzige) Farbmeßgerät 10 in Querrichtung der Stoffbahn 1 auf eine Schiene 18 automatisch verfahrbar angeordnet. Statt eines einzigen Farbmeßgeräts können auch mehrere, vorzugsweise drei derartige Geräte bzw. Meßköpfe in fester Position eingesetzt werden. Die bevorzugten Meßpositionen werden in der Zeichnung von Fig. 2 mit durchgezogenen bzw. gestrichelten Linien angedeutet. Wenn die Differenz der Farbmeßergebnisse von Null abweicht, wird ein entsprechendes Signal auf den Rechner 14 und von diesem auf die Quetsche 6 gegeben. Die Dauer und die Art der Abweichung sowie das betroffene Stoffbahnstück können über den Rechner 14 registriert und in einem der fertigen Ware mitzugebenden Protokoll ausgedruckt werden.Normally, the color depth and a difference in the measurement results for the
