Description
Die Erfindung betrifft ein Verfahren zum kontinuierlichen oder semi-kontinuierlichen Auswaschen wasserlöslicher Substanzen, insbesondere Alkalien, Säuren und anderer Elektrolyte, aus Geweben, Gewirken, Vliesen, Garnen oder Fäden aus natürlichen und synthetischen Fasern oder deren textlien Mischungen.The invention relates to a method for continuous or semi-continuous washing out of water-soluble substances, especially alkalis, acids and other electrolytes, from woven, knitted, nonwovens, yarns or threads made from natural and synthetic Fibers or their textile mixtures.
Bei der Lösungswäsche, bei welcher ein zur Erzielung einer besonderen Wirkung auf die Ware aufgebrachtes Behandlungsmittel nach der erfolgten Behandlung wieder aus der Ware entfernt werden soll, wurde bisher immer so vorgegangen, daß die Warenbahn nacheinander durch verschiedene Behandlungsabteile geführt und dort mit Wasser zusammengebracht wurde, durch das die Konzentration des in der Ware noch vorhandenen Behandlungsmittels immer weiter herabgesetzt wurde mit dem Ziel, das Behandlungsmittel möglichst restlos aus der Ware auszuwaschen. Es ist einzusehen, daß es immer schwieriger wird, die Konzentration des Behandlungsmittels noch weiter herabzusetzen, je geringer die Konzentrationsdifferenz zwischen Ware und Waschwasser schon geworden istIn the case of solution washing, in which one is applied to the goods to achieve a special effect Treatment agent to be removed again from the goods after the treatment has been carried out so far always proceeded in such a way that the web of material passed through and through different treatment compartments one after the other There it was brought together with water, through which the concentration of what is still present in the goods Treatment agent was always further reduced with the aim of keeping the treatment agent as completely as possible to wash out of the goods. It can be seen that it is becoming more and more difficult to concentrate the Reduce treatment agent even further, the lower the concentration difference between goods and wash water has already become
Untersuchungen haben nun ergeben, daß auch bei lang andauerndem Waschen selbst mit enthärtetem Frischwasser immer ein Laugen- oder Säurerest im Textilgut verbleibt. Diese Reste sind nun aber, wie sich gezeigt hat, die Ursache vielfältiger Störungen bei nachfolgenden Veredlungsbehandlungen, wie empfindlichen Färbungen oder hochwertigen Endveredlungen.Studies have now shown that even with long-term washing even with softened With fresh water, a lye or acid residue always remains in the textile. These remnants are, however, like themselves has shown the cause of various disorders in subsequent finishing treatments, such as sensitive Dyeings or high-quality finishes.
Aufgabe der vorliegenden Erfindung ist es, ein Verfahren zu schaffen, bei dem Behandlungsmittel wie Säuren oder Laugen so vollständig aus. der WareThe object of the present invention is to provide a method in which treatment agents such as Acids or alkalis so completely. the goods
ίο ausgewaschen werden, daß sie die nachfolgenden Behandlungen nicht mehr stören können,ίο be washed out that they are the following Treatments can no longer interfere,
Zur Lösung dieser Aufgabe wird erfindungsgemäß ein Verfahren zum kontinuierlichen oder semi-kontinuierlichen Auswaschen wasserlöslicher Substanzen aus Geweben, Gewirken, Vliesen, Garnen oder Fäden vorgeschlagen, bei dem unmittelbar im Anschluß an ein Auswaschen in an sich bekannter Art mit normalem Frischwasser restliche im Textilgut verbliebene Spuren von Laugen oder Säuren in einer zusätzlichen Endwaschstufe dadurch aus dem Textilgut entfernt werden, daß die am Ende des normalen Waschprozesses stark abgequetschte Textilbahn mit destilliertem oder in einem Ionenaustauscher entsalztem Wasser voll durchtränkt, in diesem gespült und nach einer Einwirkungszeit von mindestens 6 bis 8 see noch einmal stark abgequetscht wird. Zur Einsparung von Wasser bei dem gesamten Waschprozeß kann vorteilhaft das Abquetschwasser aus der abschließenden Abquetschung und das Abwasser aus dem zusätzlichen Spülen dem vorausgehenden normalen Waschprozeß als zusätzliches Frischwasser zugeführt werden. Es ist zweckmäßig, in der zusätzlichen Endwaschstufe Kondensat zu verwenden, das innerhalb oder außerhalb der Waschanlage bei der Beheizung des Waschwassers der Hauptwaschstufe anfällt.To achieve this object, the invention provides a continuous or semi-continuous process Washing out of water-soluble substances from woven, knitted, non-woven, yarn or thread proposed in which immediately following a washout in a manner known per se with normal Fresh water remaining traces of alkalis or acids in the textile in an additional Final washing step can be removed from the textile material at the end of the normal washing process heavily squeezed textile web soaked in distilled water or water desalinated in an ion exchanger, rinsed in this and again strong after an exposure time of at least 6 to 8 seconds is squeezed. In order to save water during the entire washing process, the squeezing water can advantageously be used from the final squeezing and the wastewater from the additional rinsing previous normal washing process are supplied as additional fresh water. It is appropriate to use condensate in the additional final washing stage, inside or outside the washing system when heating the washing water of the main washing stage.
Die normalerweise mit mittlerer Temperatur in die zusätzliche Waschstufe eintretende Textilbahn kann vor oder in Verbindung mit dem Tränken mit destilliertem oder entsalztem Wasser einer Kondensationsaufheizung von 1000C unterworfen werden und während der gewünschten Einwirkzeit des Zusatzwaschprozesses im Wasserdampfmedium gehalten werden.The textile web normally occurring at medium temperature in the additional washing step may be subjected to a condensation heating of 100 0 C before or in connection to the impregnation with distilled or deionized water and held in the steam medium during the desired exposure time of the additional washing process.
An Hand der Zeichnung soll ein Waschprozeß gemäß der vorliegenden Erfindung näher erläutert werden.A washing process according to the present invention will be explained in more detail with reference to the drawing.

Sie erhalten den benötigten Frischwasserzusatz A amThe four first compartments of a countercurrent washing machine with six bins 1 to 6, through which the web of material 7 is guided in the direction indicated by arrows, are connected to one another.

Die Abteile 5 und 6 arbeiten ebenfalls im Gegenstrom, jedoch wird das Wasser nicht hinter dem Abteil 5 in die Abflußleitung 8 abgelassen, sondern über Austauschfilter 10, 11 durch eine Pumpe 12 zurückgefördert. Der Durchsatz kann beispielsweise 2 bis 2,5 m3/h betragen, wobei das Austauschharz, etwa ein stark saurer Kationenaustauscher, die Natriumionen bindet. Das entalkalisierte Wasser wird dann wieder in das Abteil 6 zurückgeführt.4th compartment. The water is then drained into the drain line 8 after passing through the compartments 3, 2, 1 at B. The compartments 5 and 6 also work in countercurrent, but the water is not drained into the drain line 8 behind the compartment 5, but is conveyed back through a pump 12 via exchange filters 10, 11. The throughput can be, for example, 2 to 2.5 m 3 / h, the exchange resin, for example a strongly acidic cation exchanger, binding the sodium ions. The dealkalized water is then returned to the compartment 6.
Bei Inbetriebnahme werden die beiden Abteile 5 und 6 mit Kondenswasser gefüllt und während einer Arbeitszeit von mehreren Stunden das gesamte Volumen über die Austauschfilter umgewälzt. Wenn die Filter erschöpft sind, erfolgt eine Regeneration mit Salzsäure. Gegebenenfalls kann, um den kontinuierlichen Betrieb nicht zu stören, auf ein Wechselfilter 10,11, wie in der Figur dargestellt ist, umgeschaltet werden.When commissioning the two compartments 5 and 6 are filled with condensation and during a Working time of several hours, the entire volume circulated through the replacement filter. If the If the filters are exhausted, regeneration with hydrochloric acid takes place. Possibly can to the continuous Operation not to be disturbed, on an easy-change filter 10,11, as shown in the figure.
