Abstract

A method for the cleaning of textiles, especially of outer garments, with a prewashing bath, a main washing bath and a rinsing bath in a drum rotating in a drum housing and having liquid passages in the drum casing, the drum having alternately running times and standstill intervals, is characterised in that the standstill intervals amount to 20 to 80 seconds and between the standstill intervals the drum executes respectively 2 to 5 revolutions, in that the rotational speed of the drum generates a centrifugal force of 0.8 to 0.9 G and in that the drum used has an inside diameter of 60 to 120 cm.

Description

Bestimmte Textilien, wie insbesondere Oberbekleidungsstücke, werden heute üblicherweise einer Chemischreinigung mit Hilfe von Perchlorethylen unterzogen. Für die Verwendung von Perchlorethylen wurden aber, da es im Verdacht steht, krebserregend zu sein, in jüngerer Zeit die Vorschriften erheblich verschärft. Außerdem ist es bei der Nachbehandlung der Kleidungsstücke in der Reinigung schwerlich vollständig aus der Faser zu entfernen.Certain textiles, such as outerwear in particular, are usually subjected to dry cleaning with the help of perchlorethylene. However, since the use of perchlorethylene has been suspected to be carcinogenic, the regulations have recently been tightened considerably. In addition, it is difficult to remove completely from the fiber during the post-treatment of the clothes in the cleaning.

Aus der EP-PS 0 241 567 ist ein Verfahren zum Waschen bzw. Reinigen von Wäschestücken aus Wolle bekannt, bei dem die Wäschestücke in einer Waschtrommel gewaschen und anschließend gespült werden, die eine Waschsequenz mit einer einzigen Vorwärtsdrehung um einen Winkel von 90 bis 320° und einer nachfolgenden einzigen Rückwärtsdrehung um den gleichen Winkel ausführt. Es wurde jedoch gefunden, daß dieses Verfahren bei der Reinigung von Oberbekleidungsstücken keine ausreichende Reinigungswirkung und außerdem unerwünschte Krumpfeffekte ergibt.From EP-PS 0 241 567 a method for washing or cleaning laundry items made of wool is known, in which the laundry items are washed in a washing drum and then rinsed, the washing sequence with a single forward rotation through an angle of 90 to 320 ° and a subsequent single reverse rotation by the same angle. However, it has been found that this process does not provide a sufficient cleaning effect when cleaning outer garments and also produces undesirable shrinking effects.

Die der Erfindung zugrundeliegende Aufgabe bestand somit darin, eine Alternative für die Chemischreinigung mit Perchlorethylen zu finden, gemäß der insbesondere Oberbekleidungsstücke ohne nennswerte Krumpfung gereinigt werden können.The object underlying the invention was therefore to find an alternative for dry cleaning with perchlorethylene, according to which, in particular, outer clothing can be cleaned without any significant shrinkage.

Das erfindungsgemäße Verfahren zur Reinigung von Textilien, insbesondere von Oberbekleidungsstücken, mit einem Vorwaschbad, einem Hauptwaschbad und einem Spülbad in einer in einem Trommelgehäuse umlaufenden Trommel mit Flüssigkeitsdurchtritten im Trommelmantel, wobei die Trommel alternierend Laufzeiten und Standpausen hat, ist dadurch gekennzeichnet, daß die Standpausen 20 bis 80 sec betragen und die Trommel zwischen den Standpausen jeweils zwei bis fünf Umdrehungen ausführt, daß die Umdrehungsgeschwindigkeiten der Trommel eine Zentrifugalkraft von 0,8 bis 0,9 G erzeugt und man eine Trommel verwendet, deren Innendurchmesser 60 bis 120 cm beträgt.The method according to the invention for cleaning textiles, in particular outer garments, with a prewash bath, a main wash bath and a rinsing bath in a drum rotating in a drum housing with liquid passages in the drum jacket, the drum alternatingly having run times and stand pauses, is characterized in that the stand breaks 20 to 80 seconds and the drum makes two to five revolutions between the breaks, that the rotational speeds of the drum generate a centrifugal force of 0.8 to 0.9 G and a drum is used whose inner diameter is 60 to 120 cm.

Das erfindungsgemäße Verfahren arbeitet mit wäßrigen Waschflotten und vermeidet völlig die Verwendung organischer Lösemittel, wie Perchlorethylen. Überraschenderweise gelingt es bei Einhaltung der beschriebenen Verfahrensbedingungen, mit einer solchen wäßrigen Waschflotte auch Oberbekleidungsstücke zu reinigen, ohne daß ein Krumpfen derselben eintritt. Bisher war es unüblich, Oberbekleidungsstücke mit wäßrigen Waschflotten zu reinigen, so daß das erfindungsgemäße Verfahren ein bestehendes technisches Vorurteil überwindet.The process according to the invention works with aqueous washing liquors and completely avoids the use of organic solvents, such as perchlorethylene. Surprisingly, if the process conditions described are observed, it is also possible to clean outer garments with such an aqueous washing liquor without the same shrinking. So far it has been unusual to clean outer garments with aqueous washing liquors, so that the process according to the invention overcomes an existing technical prejudice.

Wenn die Standpausen kürzer als 20 sec sind, ist die Verformung des Waschgutes und die Verfilzungsneigung zu groß. Bei geringerer Intensität der mechanischen Einwirkung, d. h. bei geringerem Trommeldurchmesser und geringerer Zentrifugalbeschleunigung, ist die Waschwirkung nicht ausreichend.If the stand breaks are shorter than 20 seconds, the laundry is deformed and the tendency to matting is too great. With less intensity of mechanical action, i. H. with a smaller drum diameter and lower centrifugal acceleration, the washing effect is not sufficient.

Der beschriebene Rhythmus von Standpausen und Umdrehungen bewirkt, daß die Textilien in der umlaufenden Trommel nach oben genommen werden und von dort zum Boden der Trommel fallen. Hierfür ist eine bestimmte Fallhöhe und damit ein bestimmter Trommeldurchmesser erforderlich. Bevorzugt liegt der Innendurchmesser der Trommel bei 70 bis 100 cm, besonders bei 80 bis 90 cm. Weiterhin ist es bevorzugt, daß die Umdrehungsgeschwindigkeit der Trommel die Zentrifugalkraft von 0,8 bis 0,9 G jeweils, d. h. innerhalb einer jeden Folge von Standpausen und Umdrehungen, innerhalb der ersten Umdrehung erzeugt.The rhythm of breaks and revolutions described causes the textiles in the rotating drum to be taken up and from there to fall to the bottom of the drum. A certain drop height and thus a certain drum diameter is required for this. The inside diameter of the drum is preferably 70 to 100 cm, particularly 80 to 90 cm. Furthermore, it is preferred that the rotational speed of the drum have the centrifugal force of 0.8 to 0.9 G each, i.e.. H. generated within each sequence of pauses and revolutions, within the first revolution.

Eine bevorzugte Weiterbildung des Verfahrens besteht auch darin, daß sich der Flüssigkeitsstand im wesentlichen außerhalb der Trommel im Trommelgehäuse befindet und daß die Badflüssigkeit vom Sumpf der Trommel zu deren oberem Bereich umgepumpt und dort auf den Trommelinhalt aufgegeben wird. Das Umpumpen der Badflüssigkeit erzeugt eine Art Beregnung der zu behandelnden Textilien in der Trommel. Das Halten des Flüssigkeitsstandes im wesentlichen außerhalb der Trommel im Trommelgehäuse ist in manchen Waschmaschinen als sogenanntes "No Dip" bekannt. Diese Maßnahme ist in Verbindung mit den übrigen genannten Verfahrensmaßnahmen vorteilhaft, da beim Eintauchen der zu behandelnden Textilien in die Waschflotte eine geringere Waschwirkung und höhere Verfilzung erzielt werden. Der genannte Trommeldurchmesser ergibt, daß der Abstand der Oberfläche des Trommelsumpfes zu der Stelle der Badflüssigkeitsaufgabe im Bereich von 60 bis 120 cm gehalten wird.A preferred further development of the method also consists in the fact that the liquid level is essentially outside the drum in the drum housing and that the bath liquid is pumped from the bottom of the drum to its upper region and is applied there to the drum content. Pumping the bath liquid creates a kind of sprinkling of the textiles to be treated in the drum. Maintaining the liquid level essentially outside the drum in the drum housing is known in some washing machines as a so-called "no dip". This measure is advantageous in conjunction with the other procedural measures mentioned, since when the textiles to be treated are immersed in the wash liquor, less washing action and higher matting are achieved. The aforementioned drum diameter means that the distance from the surface of the drum sump to the location of the bath liquid application is kept in the range from 60 to 120 cm.

Zweckmäßig sind die Behandlungszeiten (Laufzeiten + Standpausen) im Vorwaschbad, Hauptwaschbad und Spülbad jeweils 5 bis 15 min. Bei kürzeren Behandlungszeiten vermindert sich die Waschwirkung, längere Behandlungszeiten sind ohne zusätzlichen positiven Effekt. Besonders günstig ist es, wenn die Behandlungszeit im Vorwaschbad und im Spülbad jeweils 5 bis 7 und im Hauptwaschbad 8 bis 12 min beträgt. Die Dauer der Standpausen liegt zweckmäßig bei 30 bis 60 sec. Die Anzahl der Umdrehungen zwischen den Standpausen ist zweckmäßig 2 bis 3.The treatment times (running times + stand breaks) in the prewash bath, main wash bath and rinsing bath are each 5 to 15 minutes. With shorter treatment times, the washing effect is reduced, longer treatment times have no additional positive effect. It is particularly expedient if the treatment time in the prewash and rinse baths is 5 to 7 min and in the main wash bath 8 to 12 min. The duration of the stand breaks is expediently 30 to 60 seconds. The number of revolutions between the stand breaks is expediently 2 to 3.

Zweckmäßig arbeitet man bei einer Temperatur der Waschbäder von 30 bis 35 C. Niedrigere Temperaturen verschlechtern die Reinigungswirkung. Höhere Temperaturen ergeben die Gefahr erhöhter Verfilzung oder Krumpfung.It is advisable to work at a temperature of 30 ° C to 35 ° C in the washing baths. Lower temperatures impair the cleaning effect. Higher temperatures create the risk of increased matting or shrinkage.

Erforderlichenfalls führt man die umgepumpte Badflüssigkeit vor der Einführung in die Trommel und damit vor dem Aufgeben auf den Trommelinhalt durch ein Flusenfilter, um die sich im Sumpf der Trommel ansammelnden Flusen laufend zu entfernen.If necessary, the pumped bath liquid is introduced before being introduced into the drum and thus before being placed on the drum stop through a lint filter to continuously remove the lint accumulating in the sump of the drum.

Es ist unzweckmäßig, zu wenig Badflüssigkeit in den Waschflotten zu verwenden, da hierdurch die Waschwirkung beeinträchtigt würde. Günstigerweise verwendet man jedoch für jedes Bad im erfindungsgemäßen Verfahren nur so viel Badflüssigkeit, daß sie die in der Trommel enthaltenen Textilien durchtränkt und außerdem, wenn umgepumpt wird, einen zusammenhängenden, d. h. von Luftblasenunterbrechungen freien Umpumpstrom in der Umpumpleitung ergibt. Je Kilogramm zu behandelnde Textilien in der Trommel verwendet man zweckmäßig 2,5 bis 5 I Badflüssigkeit pro Bad. Die Beladung der Trommel ist günstigerweise so , daß pro Charge 5 bis 25, vorzugsweise 7 bis 14 kg Textilien (als Trockengewicht) eingeführt werden.It is not advisable to use too little bath liquid in the washing liquors, as this would impair the washing effect. Conveniently, however, only so much bath liquid is used for each bath in the process according to the invention that it soaks the textiles contained in the drum and, moreover, if it is pumped around, a coherent, i.e. H. results in free pumping current in the pumping line from air bubble interruptions. For each kilogram of textiles to be treated in the drum, 2.5 to 5 liters of bath liquid are advantageously used per bath. The loading of the drum is advantageously such that 5 to 25, preferably 7 to 14 kg of textiles (as a dry weight) are introduced per batch.

Das erfindungsgemäße Verfahren zeigt eine stark überlegene Waschwirkung bei vergleichbarer bis geringerer Filzkrumpfung gegenüber anderen mit wäßrigen Waschflotten arbeitenden Verfahren und arbeitet völlig ohne organische Lösemittel, wie Perchlorethylen. Gegenüber anderen Waschverfahren mit wäßrigen Waschflotten kann es zu einer deutlichen Einsparung des Wasserverbrauches führen.The process according to the invention shows a strongly superior washing action with comparable to less felt shrinkage than other processes which work with aqueous washing liquors and works completely without organic solvents, such as perchlorethylene. Compared to other washing processes with aqueous washing liquors, it can lead to a significant saving in water consumption.
