Zum Abtöten von Krankheitserregern und Ungeziefer in Bekleidungsstücken und anderen Gegenständen ist vorgeschlagen worden, die Gegenstände der Einwirkung elektrischer Wechselfelder, insbesondere Ultrakurzwellenfelder mit einer Wellenlänge von weniger als ioom, auszusetzen. Zur Erhöhung der Tötungswirkung ist ferner vorgeschlagen worden, die Gegenstände in Anwesenheit von Feuchtigkeit der Feldeinwirkung auszusetzen, indem die Gegenstände vor oder/und während der Feldeinwirkung befeuchtet werden. Die Befeuchtung kann beispielsweise durch Sprühnebel oder Dampf von Wasser oder wäßrigen Lösungen geeigneter Desinfektionsmittel erfolgen.For killing pathogens and vermin in clothing and other objects has been proposed, the objects of the action of alternating electric fields, in particular Ultra-short wave fields with a wavelength of less than ioom. To the It has also been suggested to increase the killing effectiveness of the articles in presence from moisture to expose the objects before and / or during the Field exposure to be moistened. The humidification can for example by spray or Steam from water or aqueous solutions of suitable disinfectants take place.

Beim Arbeiten nach diesem Verfahren hat es sich gezeigt, daß in der Umgebung von Metallteilen an den Gegenständen, beispielsweise metallischen Knöpfen, Haken oder Schnallen an Bekleidungsstücken, eine besonders starke Erwärmung der Gegenstände auftritt. Diese Erwärmung kann so groß sein, daß beispielsweise der Faden, mit dem die Knöpfe eines Kleidungsstückes angenäht sind, brüchig wird. Unter Umständen kann sogar der Stoff in der Umgebung der Metallteile versengt werden.When working according to this method, it has been found that in the vicinity of metal parts on the objects, for example metallic buttons, hooks or buckles on items of clothing, the objects become particularly hot. This warming can be like that be large so that, for example, the thread with which the buttons of a garment are sewn on, becomes brittle. In some circumstances, the fabric around the metal parts can even scorch will.

Die Erfindung beruht auf der Erkenntnis, daß die starke Erwärmung der Stoffe in der unmittelbaren Umgebung der Metallteile durch dieThe invention is based on the knowledge that the strong heating of the substances in the the immediate vicinity of the metal parts

von den Metallteilen hervorgerufene Feldkonzentration verursacht wird. Erfindungsgemäß wird diese Überhitzung, wie praktische Versuche bestätigt haben, dadurch in einfacher Weise wirkungsvoll vermieden, daß die nähere Umgebung der Metallteile an den Gegenständen stärker befeuchtet wird als die übrigen Teile der Gegenstände. Das Verfahren kann entweder in der Weise durchgeführt werden, daß die nähere Umgebung der Metallteile besonders kräftig befeuchtet wird, oder gegebenenfalls auch in der Weise, daß nur die nähere Umgebung der Metallteile befeuchtet wird. Die letztere Verfahrensweise wird beispielsweise dann vorteilhaft sein, wenn die zu behandelnden Gegenstände z. B. infolge hoher Luftfeuchtigkeit bereits von vornherein einen gewissen Feuchtigkeitsgehalt haben. Die Befeuchtung wird zweckmäßig mit einei Nebelspritzpistole oder einem ähnlichen Zerstäubungsgerät vorgenommen.field concentration caused by the metal parts. According to the invention this overheating, as practical tests have confirmed, is thus effective in a simple manner avoided that the closer environment of the metal parts on the objects moistened more strongly is called the remaining parts of the objects. The procedure can be either in the manner be carried out so that the immediate vicinity of the metal parts is particularly strongly moistened, or possibly in such a way that only the immediate vicinity of the metal parts is moistened will. The latter procedure will be advantageous, for example, when the to be treated Objects e.g. B. due to high humidity a certain moisture content from the outset to have. The moistening is expedient with a mist spray gun or similar Nebulizer made.

Die Wirkung des Verfahrens beruht offenbar darauf, daß infolge der großen Dielektrizitätskonstante von Wasser eine homogenere Feldverteilung erzielt wird. Außerdem wird ein zu starker Temperaturanstieg in den vorzugsweise befeuchteten Teilen dadurch vermieden, daß die absorbierte Energie zur Verdampfung der Feuchtigkeit verbraucht wird.The effect of the method is apparently based on the fact that due to the large dielectric constant a more homogeneous field distribution is achieved by water. In addition, too great a temperature rise in the is preferred Moistened parts avoided by allowing the absorbed energy to evaporate the moisture is consumed.
