Description
Die Erfindung betrifft ein Verfahren zur Herstellung von mit einem Anlaufschutzmittel für Silberwaren versehenen Textilien durch Imprägnieren mit wäßrigen Lösungen von schwefelwasserstoffbindenden Metallsalzen. The invention relates to a method for the production of anti-tarnish agents for silver goods Textiles by impregnating with aqueous solutions of metal salts that bind hydrogen sulfide.
Es ist bekannt, Textilien, die zur Verpackung von Silbergeräten dienen, zum Schutz gegen das Anlaufen des Silbers mit Eisendoppelsalzen oder Zinksalzen zu tränken. Es ist weiterhin bekannt, an Stelle derartig getränkter Textilien die Anlaufschutzmittel, z. B. aus Caduiiumsalzen, als flache Blätter oder Tabletten den Verpackungen als unabhängige, auswechselbare Einlagekörper beizulegen, was die Verpackung aber umständlichmacht. Verwendet man Silbersalze, so werden Silbersalze mit der Zeit unter Lichteinwirkung in metallisches Silber zersetzt und die Textilien werden dabei so verfärbt, daß man z. B. nur dunkelbraune oder dunkelblaue Textilien verwenden kann. Der Erfindung liegt die Aufgabe zugrunde, die genannten Nachteile zu vermeiden und beliebig farbige Textilien zu verwenden. It is known that textiles used for packaging silver devices to protect against tarnishing to impregnate the silver with iron double salts or zinc salts. It is also known in place of such soaked textiles the anti-tarnish agents, z. B. from Caduiiumsalzen, as flat sheets or tablets the Include packaging as independent, replaceable insert bodies, which makes the packaging cumbersome. If silver salts are used, silver salts turn into metallic ones over time when exposed to light Silver decomposes and the textiles are discolored so that one z. B. only dark brown or can use dark blue textiles. The invention is based on the stated disadvantages to avoid and to use textiles of any color.
Diese Aufgabe wird erfindungsgemäß durch ein Verfahren zur Herstellung von mit einem Anlaufschutzmittel für Silberwaren versehenen Textilien durch Imprägnieren mit wäßrigen Lösungen von schwefelwasserstoffbindenden Metallsalzen, die ungefärbte bis schwach gefärbte Sulfide ergeben, dadurch gelöst, daß man die schwefelwasserstoffbindenden Metallsalze, die ungefärbte bis schwach gefärbte Sulfide ergeben, in Kombination mit hygroskopisch wirksamen anorganisehen Salzen und/oder organischen hygroskopischen Verbindungen, soweit sie mit den verwendeten Metallsalzen keine Ausfällungen ergeben, auf die Textilien aufbringt.According to the invention, this object is achieved by a process for the production of an anti-tarnish agent for textiles provided with silver goods by impregnation with aqueous solutions of hydrogen sulfide binding agents Metal salts which give uncolored to pale colored sulfides, dissolved in that the metal salts which bind hydrogen sulfide and give uncolored to pale colored sulfides are put into Combination with hygroscopic inorganic salts and / or organic hygroscopic salts Compounds, as long as they do not result in precipitations with the metal salts used, on the textiles brings up.
Als Schwefelwasserstoff bindende Substanzen werden solche Metallsalze verwendet, die ungefärbte bzw. schwach gefärbte Sulfide ergeben, z. B. Zink-, Manganoder Cadmiumsalze. Die im Vergleich zu Silber geringere Reaktionsfähigkeit dieser Metallsalze gegen Schwefelwasserstoff wird erfindungsgemäß weitgehendst dadurch aufgehoben, daß die Schwefelwasserstoff bindenden Substanzen nicht allein, sondern nur in Kombination mit hygroskopischen Substanzen verwendet werden und dadurch auf den auszurüstenden Textilien zumindest zum Teil in leicht angelöster und deshalb in wesentlich reaktionsfähigerer Form vorliegen. The metal salts used as hydrogen sulfide-binding substances are those which are uncolored or result in weakly colored sulfides, e.g. B. zinc, manganese or cadmium salts. The lower compared to silver According to the invention, the reactivity of these metal salts towards hydrogen sulfide is as great as possible repealed by the fact that the hydrogen sulfide binding substances not alone, but only in Combination with hygroscopic substances can be used and thereby on the to be equipped Textiles are at least partially in a slightly loosened and therefore much more reactive form.
Die ursprünglich geringere Reaktionsfähigkeit wird weiterhin auch dadurch ausgeglichen, daß die erfindungsgemäß zu verwendenden Substanzen in unvergleichbar höherem Maße eingesetzt werden als nach einem früheren Verfahren die Silbersalze.The originally lower reactivity is also compensated for by the fact that the invention substances to be used are used to an incomparably higher degree than after an earlier process the silver salts.
Untersuchungen haben ergeben, daß die Kombination der genannten Metallsalze mit hygroskopisch wirksamen Substanzen die Schutzwirkung gegen Schwefelwasserstoff in einem nicht vorhersehbaren Maß steigert.Studies have shown that the combination of the metal salts mentioned with hygroscopic effective substances the protective effect against hydrogen sulfide in an unpredictable way Measure increases.
Als hygroskopische Substanzen kommen sowohl hygroskopische anorganische Salze als auch hygroskopische organische Körper in Frage, soweit sie mit den anzuwendenden Metallsalzen keine Ausfällungen ergeben.Both hygroscopic inorganic salts and hygroscopic salts come as hygroscopic substances organic bodies in question, as long as they do not precipitate with the metal salts to be used result.
Die auf diese Weise ausgerüsteten Textilien dienen in erster Linie zum Ausschlagen von Etuis, in denen Silbergegenstände aufbewahrt werden, z. B. zur Herstellung von Besteckkästen. Andere Anwendungsgebiete sind aber dadurch nicht ausgeschlossen.The textiles finished in this way are primarily used to knock out cases containing silver objects be kept, e.g. B. for the production of cutlery boxes. Other areas of application but are not excluded by this.
Anlauf schützend auszurüstende Textilien, z. B. Filze, werden trocken in ein Bad getaucht, das 300 g/1 Zinkacetat und 50 g/l Glyzerin enthält. Abquetscheffekt 100 °/o, Trocknung wie üblich.Protective textiles to be given a start-up, e.g. B. Felts are immersed dry in a bath that 300 g / 1 Contains zinc acetate and 50 g / l glycerine. Squeeze effect 100%, drying as usual.
Anlaufschützend auszurüstende Textilien werden trocken in ein Bad getaucht, das 200 g 1 Mangansulfat und 50 g/l Magnesiumchlorid enthält. Abquetscheffekt 100%, Trocknung wie üblich.Textiles to be treated with tarnish protection are dipped dry in a bath containing 200 g of 1 manganese sulfate and contains 50 g / l magnesium chloride. 100% squeeze effect, drying as usual.
Anlaufschützend auszurüstende Textilien werden trocken in ein Bad getaucht, das 200 g/l Cadmiumsulfat und 50 g/l Glyzerin enthält. Abquetscheffekt °/o, Trocknung wie üblich.Textiles to be treated with tarnish protection are dipped dry in a bath containing 200 g / l cadmium sulfate and contains 50 g / l glycerine. Squeeze-off effect, drying as usual.
Eine Verfärbung durch die Ausrüstung sowie durch eine anschließende Begasung mit Schwefelwasserstoff als Gebrauchstest ist kaum sichtbar.Discoloration due to the equipment and subsequent fumigation with hydrogen sulfide as a use test is hardly visible.
