KLASSE 8: Bleichen, Färben, Zeugdruck und Appretur.CLASS 8: Bleaching, dyeing, fabric printing and finishing.

. Patentirt im Deutschen Reiche vom la. November 1897 ab.. Patented in the German Empire from la. November 1897.

Es ist bekannt, dafs Alkohol und. Aldehyd beim Soupliren und Färben als Zusatz zu den Öpcrationsbädern gute Ergebnisse liefern. Es darf wohl angenommen werden, dafs die Wirkungen, welche man erzielt, darauf beruhen, dafs Alkohol und Aldehyd die Seidenfaser als. solche nicht angreifen, ja sogar den Seidenleim unlöslich machen, wie beispielsweise durch Anwendung von Formaldehyd iii der Souplefärberei dargcthan wird. .It is known that alcohol and. aldehyde give good results when souping and dyeing as an additive to the opening baths. It it may well be assumed that the effects which are achieved are based on that alcohol and aldehyde are the silk fibers. do not attack such, even the silk glue make them insoluble, for example by using formaldehyde iii souple dyeing dargcthan will. .

Beim Studium der Einwirkung von Alkoholen, Aldehyden und Ketonen auf die Textil-, fasern hat die Patentinhaberin eine neue "eigen-, thümliche Wirkung dieser Körper in der Bleicherei der Gespinnstfasern, besonders in der Seidenbleiche,'festgestellt.When studying the effects of alcohols, aldehydes and ketones on the textile, fibers the patent proprietor has a new "peculiar, peculiar effect of these bodies in the Bleaching of staple fibers, especially in bleaching silk, 'noted.

Setzt man zu den Bleichbadern, welche Wasserstoffsuperoxyd oder Alkalisuperoxyd und die zugehörigen !Hilfsmittel, wie z.B. Ammoniak, Wasserglas oder Magnesiumsulfat, enthalten, irgend einen flüssigen Alkohol der Fettreihe, welcher sich mit Wasser mischt, ,wie Methyl- und Aethylalkohol, Glycerin, einen ebenso beschaffenen Aldehyd, wie Aethyl-Aldchyd, oder ein Keton von gleicher Eigenschaft wie Aceton, so zeigt sich neben der Schonung der Faser ein erheblich gröfserer Bleicheffekt als ohne diese Zusätze.If you add to the bleach baths, which hydrogen peroxide or alkali peroxide and Contain the associated aids, such as ammonia, water glass or magnesium sulfate, any liquid alcohol of the fatty series, which mixes with water, such as methyl and ethyl alcohol, glycerine, an aldehyde of the same nature as ethyl aldehyde, or a ketone of the same properties as acetone, then appears next to the Preservation of the fiber has a considerably greater bleaching effect than without these additives.

Während rohe gelbe Seide rein weifs bisher nur zu erhalten war, wenn der Bast entfernt wurde, ist es nach der vorliegenden Erfindung lcPcht möglich, sie oh η e Bastverlust völlig wcifs zu erhalten. Rohseiden, Souples, Cuites, das sind abgekochte Seiden, Schappcs, Bourrettes, Seidenwatten, Cocons, Tussah, und die mit Zinnverbindungen behandelten Seiden, kurz jede Seidenart beliebiger Herkunft und in jedem Zustande ihrer Verarbeitung — auch der Färberei — liefern, wenn sie diesem Verfahren unterworfen werden, eine erheblich klarere Bleiche als bisher und demgemäfs auch reinere Farben.While raw yellow silk in pure white was previously only available when the bast was removed according to the present invention, it is perfectly possible to completely eliminate them without loss of bast to receive wcifs. Raw silks, souples, cuites, these are boiled silks, Schappcs, Bourrettes, Silk wadding, cocoons, tussah, and the silks treated with tin compounds, in short, any type of silk of any origin and in any state of its processing - also of dyeing - when subjected to this process, provide a substantial clearer bleaching than before and accordingly also purer colors.

Die Alkohol-, Aldehyd- oder Keton-Zusätze werden· natürlich als werthvolle Bestandteile aus den Bleichbädern zurückgewonnen.The alcohol, aldehyde or ketone additives are naturally valuable components recovered from the bleach baths.

Die Temperatur des Bades und die Menge der Zusätze von Alkohol, Aldehyd oder Keton richtet sich nach dem Material, der Zeit, in welcher die Bleiche beendet sein soll, und dem gewünschten Ton der Bleiche.The temperature of the bath and the amount of alcohol, aldehyde or ketone added depends on the material, the time in which the bleaching should be finished, and the desired tone of bleach.

Beispiel I.Example I.

In einem geschlossenen, mit Rückflufskühler versehenen Gefäfs erhitzt man 5 kg gelbbastige rohe Seide von beliebigem Draht mit 10 kg Wasserstoffsuperoxyd des Handels von 3 pCt. und 10 kg rohem Aceton oder einem Alkohol oder einem Aldehyd nebst der nöthigen Menge Ammoniak, um die Säure des Wasserstoffsuperoxydes zu neutralisiren, eine Stunde zum Siedepunkt. Nach dieser Zeit wird die Seide weifser als die gleichwertige Weifsbastseide sein, und,zwar ohne merklichen Verlust.In a closed, with reflux condenser In the vessel provided, 5 kg of yellow-basted raw silk from any wire with 10 kg is heated Commercial hydrogen peroxide of 3 pCt. and 10 kg of crude acetone or an alcohol or an aldehyde, together with the necessary amount of ammonia, for the acid of hydrogen peroxide to neutralize, one hour to the boiling point. After this time the silk becomes Whiter than the equivalent white bast silk without any noticeable loss.

Beispiel H.Example H.

5 kg abgekochte Schappe wird kalt mit etwa 15 kg Wasserstoffsuperoxyd und etwa ι ο kg Spiritus oder einem anderen Alkohol, einem Aldehyd oder einem Keton nebst Ammoniak in einem Bade 24 bis 48 Stunden zeitweise5 kg of boiled Schappe becomes cold with about 15 kg of hydrogen peroxide and about ι ο kg Spirit or another alcohol, an aldehyde or a ketone together with ammonia in a bath for 24 to 48 hours at times

umgelegt. Die Seide wird weifser erhalten, als es auf bisherige Art möglich ist.knocked down. The silk will get whiter, than is possible in the previous way.

Denselben oder einen noch besseren Effekt erzielt man in kürzester Zeit in etwa ι Stunde, wenn man zum Sieden erhitzt.The same or an even better effect can be achieved in a very short time in about 1 hour, when heated to the boil.

Das Verfahren für die anderen Textilstoffe ist das gleiche.The procedure for the other fabrics is the same.
