Description

Die Erfindung betrifft ein Verfahren zum Spülen von Textilgut in einer Kufe nach einer Nassbehandlung, wobei Frischwasser auf das in der Kufe im endlosen Umlauf gehaltene Textilgut aufgebrachtwird, das Textilgut eine flottenfreie Verweilzone durchsetzt und in einer Entwässerungszone Haftwasser aus dem Textilgut abgequetscht wird.The invention relates to a method for rinsing textile goods in a runner after a wet treatment, fresh water being applied to the textile goods kept circulating in the runner, the textile goods passing through a floating residence zone and adhesive water being squeezed out of the textile goods in a dewatering zone.

Es ist ein Verfahren zum Spülen von Textilgut in einer Kufe nach einer Nassbehandlung bekannt (US-A Nr. 2240809), wobei der untere Teil der Kufe eine mit Spülflotte gefüllte Verweilzone bildet. Das in endlosem Umlauf gehaltene Textilgut durchläuft - wenn es aus der Spülflotte herausgezogen wird - zunächst ein Quetschwalzenpaar. Auf das dann über eine Transportwalze wieder der Spülflotte zugeführte Textilgut wird Frischwasser aufgedüst. Der wesentliche Nachteil dieses bekannten Spülverfahrens liegt in der zur Erzielung eines einwandfreien Spülergebnisses benötigten grossen Wassermenge.A method for rinsing textile material in a runner after a wet treatment is known (US-A No. 2240809), the lower part of the runner forming a residence zone filled with washing liquor. The textile goods, which are kept in endless circulation, first run through a pair of squeeze rollers when they are pulled out of the washing solution. Fresh water is sprayed onto the textile material which is then returned to the washing liquor via a transport roller. The main disadvantage of this known rinsing method is the large amount of water required to achieve a perfect rinsing result.

Es ist weiterhin ein Verfahren zum Spülen von Textilgut bekannt (GB-A Nr. 237422), wobei das im endlosen Umlauf enthaltene Textilgut eine flottenfreie Verweilzone im unteren Bereich der Kufe durchsetzt. Sowohl auf das aus der Verweilzone nach oben laufende Trum des Textilgutes als auch auf das wieder nach unten in die Verweilzone geführte Trum des Textilgutes wird bei diesem bekannten Verfahren Frischwasser aufgespritzt. Im oberen Bereich der Kufe durchsetzt das Textilgut eine durch ein Quetschwalzenpaar gebildete Entwässerungszone. Bei diesem Verfahren ergibt sich bereits durch Verwendung einer flottenfreien Verweilzone eine wesentliche Verringerung der benötigten Wassermenge und eine Verbesserung des Spülergebnisses.A method for rinsing textile material is also known (GB-A No. 237422), the textile material contained in the endless circulation passing through a floating residence zone in the lower region of the runner. In this known method, fresh water is sprayed onto both the run of the textile goods running upward from the dwelling zone and the run of the textile goods running down again into the dwelling zone. In the upper area of the runner, the textile material passes through a drainage zone formed by a pair of squeeze rollers. In this method, the use of a floating residence zone already results in a significant reduction in the amount of water required and an improvement in the washing result.

Der Erfindung liegt nun die Aufgabe zugrunde, ein Verfahren der eingangs genannten Art so auszubilden, dass noch eine weitere Verringerung der benötigten Spülwassermenge erreicht wird.The invention is based on the object of developing a method of the type mentioned at the outset such that a further reduction in the amount of flushing water required is achieved.

Diese Aufgabe wird erfindungsgemäss durch folgende Merkmale gelöst:

  • a) das gesamte Frischwasser wird - in Umlaufrichtung des Textilgutes gesehen - nach der Entwässerungszone und vor der Verweilzone auf das Textilgut aufgebracht;
  • b) die Menge des aufgebrachten Frischwassers ist höchstens gleich der Wassermenge, die das Textilgut beim Eintritt in die Verweilzone tragen kann.
According to the invention, this object is achieved by the following features:
  • a) the entire fresh water - seen in the direction of circulation of the textile goods - is applied to the textile goods after the dewatering zone and before the dwell zone;
  • b) the amount of fresh water applied is at most equal to the amount of water that the textile material can carry when entering the dwell zone.

Indem beim erfindungsgemässen Verfahren das gesamte Frischwasser nach der Entwässerungszone, jedoch vor der Verweilzone auf das Textilgut aufgebracht wird, erreicht man eine maximale Einwirkungszeit des Frischwassers auf das Textilgut, ehe dieses Spülwasser beim erneuten Durchlauf des Textilgutes durch die Entwässerungszone wieder entfernt wird. Auf diese Weise erhält man eine optimale Wirkung der für den Spülvorgang eingesetzten Wassermenge.By applying all the fresh water after the dewatering zone but before the dwell zone to the textile material in the process according to the invention, a maximum exposure time of the fresh water to the textile material is achieved before this rinsing water is removed again when the textile material passes through the dewatering zone again. In this way you get an optimal effect of the amount of water used for the rinsing process.

Im Unterschied zu den bisher bekannten Verfahren wird bei der erfindungsgemässen Lösung ferner höchstens nur soviel Frischwasser auf das Textilgut aufgebracht, wie das Textilgut beim Eintritt in die Verweilzone tragen kann. Man vermeidet somit die Zugabe von Frischwasser im Überschuss, da der vom Textilgut nicht aufgenommene Wasseranteil im Hinblick auf den flottenfreien Zustand der Verweilzone keine nennenswerte Spülwirkung erfüllen könnte. Auf diese Weise lässt sich mit dem erfindungsgemässen Verfahren die benötigte Frischwassermenge auf ein Minimum bringen, was nicht zuletzt wegen des für die Abwasserreinigung erforderlichen Aufwandes ein wesentlicher Vorteil ist.In contrast to the previously known methods, in the solution according to the invention, at most only as much fresh water is applied to the textile material as the textile material can carry when entering the dwell zone. This avoids the addition of fresh water in excess, since the water content not absorbed by the textile material could not have any noteworthy rinsing effect in view of the floating condition of the dwelling zone. In this way, the amount of fresh water required can be reduced to a minimum with the method according to the invention, which is a significant advantage not least because of the effort required for wastewater treatment.

Die Erfindung wird im folgenden anhand eines in der Zeichnung veranschaulichten Ausführungsbeispieles näher erläutert.The invention is explained below with reference to an embodiment illustrated in the drawing.

Die dargestellte Nassbehandlungskufe 1 besitzt ein Kufengehäuse 2, dessen unterer Teil durch einen inneren Einbauteil 3 die Form eines kanalartigen Verweilstiefels 4 aufweist.The wet treatment skid 1 shown has a skid housing 2, the lower part of which has the shape of a channel-like stay boot 4 due to an inner installation part 3.

Im oberen Teil 2a des Kufengehäuses 2 sind eine Anzahl von Umlenk- und Transportwalzen 5, 6, 7, 8 angeordnet, von denen wenigstens eine durch nicht näher veranschaulichte Antriebseinrichtungen angetrieben ist. Diese Walzen 5,6,7,8 können in Transportrichtung (Pfeil 9) des zu behandelnden strangförmigen Textilgutes 10 schräg ansteigend angeordnet sein, wobei sie parallel zueinander liegen und jeweils teilweise von dem Textilgut 10 umschlungen werden.In the upper part 2a of the runner housing 2, a number of deflection and transport rollers 5, 6, 7, 8 are arranged, at least one of which is driven by drive devices, not shown. These rollers 5, 6, 7, 8 can be arranged so as to rise obliquely in the direction of transport (arrow 9) of the strand-like textile material 10 to be treated, whereby they lie parallel to one another and are each partially wrapped around by the textile material 10.

Die beiden Walzen 5, 6 bilden ein Quetschwalzenpaar, zwischen dem das aus dem Verweilstiefel 4 aufsteigende Textilgut 10 hindurchgeführt wird. Unterhalb dieses Quetschwalzenpaares 5, 6 ist eine Auffangrinne für abgequetschtes Haftwasser 12 angeordnet. An diese Auffangrinne 11 ist eine - nur gestrichelt angedeutete - Abzugsleitung 13 angeschlossen, über die abgequetschtes Haftwasser von der Auffangrinne 11 aus dem Innern der Kufe 1 abgezogen werden kann.The two rollers 5, 6 form a pair of squeeze rollers, between which the textile material 10 rising from the dwelling boot 4 is passed. Below this pair of squeeze rollers 5, 6, a collecting channel for squeezed-off adhesive water 12 is arranged. To this collecting trough 11 is connected an extraction line 13 - only indicated by dashed lines - via which squeezed-off adhesive water can be drawn off from the collecting trough 11 from the inside of the runner 1.

Über der - im Umlaufrichtung (Pfeil 9) des Textilgutes 10 gesehen - letzten Umlenk- und Transportwalze 8 ist eine Frischwasserzufuhreinrichtung 14 vorgesehen. Sie enthält wenigstens eine Spritzdüse 15, deren Wasserzufuhrmenge einstellbar ist, sowie eine Wasserzufuhrleitung 16 mit einem Einstellventil 17. Besonders günstig ist die Anordnung der Spritzdüse 15 im Bereich oberhalb des Scheitelpunktes der letzten Umlenk- und Transportwalze 8.A fresh water supply device 14 is provided above the last deflection and transport roller 8, as seen in the direction of rotation (arrow 9) of the textile material 10. It contains at least one spray nozzle 15, the water supply quantity of which is adjustable, and a water supply line 16 with an adjusting valve 17. The arrangement of the spray nozzle 15 in the region above the apex of the last deflection and transport roller 8 is particularly favorable.

Das Spülen von strangförmigem Textilgut 10 geschieht folgendermassen:The washing of strand-like textile material 10 takes place as follows:

Es sei angenommen, dass das in der Nassbehandlungskufe 1 befindliche, endlos in Richtung der Pfeile 9 umlaufende strangförmige Textilgut 10 zunächst gefärbt wurde und nach beendetem Färbevorgang die Färbeflotte aus dem Kufengehäuse 2 abgezogen wurde.It is assumed that the strand-like textile material 10 which is located in the wet treatment skid 1 and which runs endlessly in the direction of the arrows 9 was first dyed and that the dyeing liquor was removed from the skid housing 2 after the dyeing process had ended.

Das danach weiterhin endlos im Kufengehäuse 2 umlaufende Textilgut 10 gelangt zunächst in die im wesentlichen von dem Quetschwalzenpaar 5, 6 und der Auffangrinne 11 gebildeten Entwässerungszone, in der Haftwasser 12 aus dem Textilgut 10 abgequetscht wird; dieses Haftwasser wird über die Auffangrinne 11 und die Abzugsleitung 13 aus der Kufe 1 abgezogen. Das entwässerte Textilgut 10 kommt dann zur Frischwasserzufuhreinrichtung 14. In dieser Zone wird im Bereich des Scheitelpunktes der Walze 8 die erforderliche Menge Frischwasser durch die Spritzdüse 15 aufgespritzt, wobei diese zugeführte Frischwassermenge höchstens so gross ist, wie sie vom Textilgut 10 getragen werden kann. Das Textilgut 10 läuft dann nach unten in die vom Verweilstiefel 4 gebildete Verweilzone. Hier erfolgt der gewünschte Stoffaustausch zwischen dem zugeführten Frischwasser und den im Textilgut 10 enthaltenen Schmutz- bzw. Farbstoffsubstanzen. Beim nächsten Umlauf des Textilgutes wiederholt sich dann der erläuterte Vorgang (Entfernen des Haftwassers, Zuführen von Frischwasser, Verweilen).The textile material 10 which then continues to circulate endlessly in the runner housing 2 first reaches the dewatering formed essentially by the pair of squeeze rollers 5, 6 and the collecting trough 11 recovery zone in which adhesive water 12 is squeezed out of the textile material 10; this adhesive water is withdrawn from the runner 1 via the gutter 11 and the discharge line 13. The dewatered textile material 10 then comes to the fresh water supply device 14. In this zone, in the region of the apex of the roller 8, the required amount of fresh water is sprayed on through the spray nozzle 15, this fresh water quantity supplied being at most as large as can be carried by the textile material 10. The textile material 10 then runs down into the dwell zone formed by the dwelling boot 4. Here, the desired mass transfer takes place between the fresh water supplied and the dirt or dye substances contained in the textile material 10. The next time the textile goods are circulated, the process described is repeated (removal of the adhesive water, supply of fresh water, lingering).

Die Kufe kann entweder mit einer einzigen Nassbehandlungskammer (wie in der Zeichnung dargestellt) oder mit mehreren, senkrecht zur Zeichenebene hintereinander liegenden Kammern ausgeführt sein. In letzterem Fall kann entweder in jeder dieser Kammern ein einziger, ringförmiger Textilgutstrang umlaufen, oder es können mehrere Kammern nacheinander vom Textilgut in Schraubenlinienform durchsetzt werden. In diesem letzteren Falle besteht die weitere Möglichkeit, das in einer Kammer aus dem Textilgutstrang entfernte Haftwasser einer zweiten Nassbehandlungskammer als Frischwasser zuzuführen, wobei zweckmässig die Frischwasserzufuhr im Gegenstrom zur Transportrichtung des Textilgutes erfolgt.The runner can either be designed with a single wet treatment chamber (as shown in the drawing) or with several chambers one behind the other perpendicular to the plane of the drawing. In the latter case, either a single, ring-shaped strand of textile material can circulate in each of these chambers, or several chambers can be penetrated by the textile material in a helical shape one after the other. In the latter case, there is the further possibility of supplying the adhesive water removed from the strand of textile material in a chamber to a second wet treatment chamber as fresh water, the fresh water supply expediently taking place in countercurrent to the direction of transport of the textile material.
