Verfahren zum elektrolytfreien WaschenElectrolyte-free washing method
Die Erfindung betrifft ein Verfahren zum kontinuierlichen Auswaschen von Säuren, Laugen und dgl. vorzugsweise aus Textilbahnen.The invention relates to a method for continuous washing of acids, alkalis and the like. Preferably from textile webs.
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 Behandlungsraittels noch weiter herabzusetzen je geringer die Konzentrationsdifferenz zwischen Ware und Waschwasser schon geworden ist.In the solution wash, in which one to achieve a special Effect of the treatment agent applied to the goods after the Treatment is to be removed from the goods again, so far the procedure has always been that the material web through one after the other different treatment compartments were led and brought together with water, through which the concentration of the in the goods was still existing treatment agent was further reduced with the aim of washing the treatment agent out of the goods as completely as possible. It can be seen that it is becoming more and more difficult to ever lower the concentration of the treatment agent the concentration difference between the goods and wash water has already decreased.
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 gezeigtInvestigations have now shown that even after prolonged washing Even with softened fresh water, a lye or acid residue always remains in the textile. But these remains are now, as has been shown

hat, die Ursache, vielfältiger Störungen bei nachfolgenden Veredlungsbehandlungen, wie empfindlichen Färbungen oder hochwertigen Endveredlungen und dgl.has, the cause, of various disorders in subsequent finishing treatments, such as sensitive colors or high-quality finishing and the like.
Aufgabe der vorliegenden Erfindung ist es, ein Verfahren zu schaffen, bei dem Behandlungsmittel wie Säuren, Laugen usw. so vollständig aus der Ware ausgewaschen werden, daß sie die nachfolgenden Behandlungen nicht mehr stören können.The object of the present invention is to provide a method create, in the treatment agents such as acids, alkalis, etc. are so completely washed out of the goods that they can no longer interfere with subsequent treatments.
Zur Lösung dieser Aufgabe wird erfindungsgemäß ein Verfahren zum kontinuierlichen oder semikontinuierlichen Entfernen bzw. Auswaschen wasserlöslicher Substanzen insbesondere Alkali, Säuren und anderen Elektrolyten aus Waren wie Geweben, Gewirken, Vliesen, Fäden, Garnen aus natürlichen und künstlichen Fasern oder deren textilen Mischungen vorgeschlagen, bei dem eines Waschprozeß mit normalem Frischwasser an sich bekannter Art ein Waschprozeß nachgeschaltet ist, bei dem die Ware zum Auswaschen letzter Behandlungsmittelreste der Einwirkung von elektrolytfreiem oder vorzugsweise durch Ionenaustausch entsalztem Wasser ausgesetzt wird.To achieve this object, according to the invention, a process for continuous or semi-continuous removal or washing out is provided water-soluble substances, in particular alkali, acids and other electrolytes from goods such as woven, knitted, fleece, Threads, yarns made from natural and artificial fibers or their textile mixtures are proposed in which a washing process is included normal fresh water of a type known per se is followed by a washing process in which the goods are used to wash out the last residues of the treatment agent is exposed to the action of electrolyte-free water or, preferably, water that has been desalinated by ion exchange.
Es hat sich als vorteilhaft erwiesen die Ware vor der Behandlung mit dem elektrolytfreiem oder entsalztem Wasser stark abzuquetschen und nach einer Einwirkzeit des elektrolytfreien bzw. entsalzten Wassers von mindestens 6 bis 8 Sek. noch einmal stark abzuquetschen. Zur Einsparung von Wasser bei dem gesamten Waschprozeß kann vorteilhaft das Abquetschwasser aus der abschließenden Abquetschung und das Abwasser aus dem etwaigen 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.It has been shown to be beneficial with the goods before treating strongly squeeze the electrolyte-free or demineralized water and After allowing the electrolyte-free or desalinated water to act for at least 6 to 8 seconds, squeeze it again vigorously. To the Saving water in the entire washing process can be advantageous the squeeze water from the final squeeze and the wastewater from any additional rinsing the preceding one normal washing process can be supplied as additional fresh water. It is advisable to use condensate in the additional final washing stage, which is inside or outside the washing system during heating of the washing water of the main washing stage is obtained.
Die normalerweise mit mittlerer Temperatur in die zusätzliche Waschstufe eintretende Textilbahn kann vor oder in Verbindung mit dem Tränken mit elektrolytfreiem oder entsalztem Wasser einer Kondensationsaufheizung von ca. 100 C unterworfen werden und während der gewünschten Einwirkzeit des Zusatzwaschprozeeses im Wasserdampfmedium gehalten werden.The textile web, which normally enters the additional washing stage at a medium temperature, can be carried out before or in connection with soaking in electrolyte-free or demineralized water with condensation heating of approx. 100 C and during the desired exposure time of the additional washing process in the steam medium being held.

Anhand der beiliegenden Zeichnung soll ein Waschprozeß gemäß der Torliegenden Erfindung näher erläutert werden.A washing process according to the present invention will be explained in more detail with the aid of the accompanying drawing.
Die rier ersten Abteile einer sechskästigen Gegenstromwaschmaschine werden Miteinander Terbunden und erhalten den benötigten Frischwasserzusatz bei A. Die Abteile 5 und 6 arbeiten im Gegenetrom, jedoch wird das Wasser nicht in den Abfluß B1 sondern mit einer Pumpe 12 durch Auetauschfilter gefördert. Der Durchsatz kann beispielsweise ca. 2 - 2,5 m/Std. betragen, wobei das Austauschharz, etwa ein stark saurer Kationenaustauscher die Natriumionen bindet. Das entalkalisierte Wasser wird dann wieder in das Abteil 6 zurückgeführt.The rier first compartments of a six-box countercurrent washing machine are connected to each other and receive the required fresh water addition at A. Compartments 5 and 6 work in counter flow, but the water is not conveyed into drain B 1 but with a pump 12 through exchange filters. The throughput can, for example, be approx. 2 - 2.5 m / hour. The exchange resin, for example a strongly acidic cation exchanger, binds 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 daβ 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 starting up, the two compartments 5 and 6 are filled with condensation filled and the entire volume circulated over the replacement filter over a period of several hours. If the If the filters are exhausted, regeneration with hydrochloric acid takes place. If necessary, in order not to disrupt continuous operation, can be switched to an easy-change filter 10, 11 as shown in the figure.
