Der Gegenstand vorliegender Erfindung ist ein Verfahren zur Herstellung künstlicher Seide.The object of the present invention is a method for producing artificial ones Silk.
Bei Behandlung von Zellulose mit Kupfer-5 oxydammoniak geht nur eine verhältnismäßig kleine Menge Zellulose in Lösung. Man hat daher bereits versucht, durch Einwirkung von Oxydationsmitteln auf die Zellulose deren Löslichkeit zu erhöhen.When cellulose is treated with copper-oxydammonia, only one is relatively effective small amount of cellulose in solution. Attempts have therefore already been made by the action of Oxidizing agents on the cellulose to increase its solubility.
ίο Nach vorliegendem Verfahren wird nun Ozon oder ozonisierte Luft als Oxydationsmittel verwendet, und zwar in Gegenwart alkalischer Flüssigkeiten, wie Soda- und Pottaschelösung, in der Weise, daß man die Zellulose in einem Bad von Soda- oder Pottaschelösung der Wirkung eines durch die Lösung hindurchgehenden Stromes von Ozon oder ozonisierter Luft aussetzt.ίο According to the present procedure, ozone or ozonated air is now used as an oxidizing agent used in the presence of alkaline liquids such as soda and potash solution, in such a way that you put the cellulose in a bath of soda or potash solution subject to the action of a current of ozone or ozonated air passing through the solution.
Die so vorbereitete Baumwolle oder Zellulose löst sich in Kupferoxydammoniäk schnell und in bedeutender Menge auf. Die Lösung ist durchaus gleichmäßig, ebenso der gebildete Faden, der außerdem große Festigkeit und Elastizität besitzt.The cotton or cellulose prepared in this way dissolves quickly in copper oxide ammonia and in significant quantities. The solution is thoroughly uniform, as is the educated one A thread that also has great strength and elasticity.
Zur Ausführung des Verfahrens verfährt man beispielsweise folgendermaßen:To carry out the procedure, one proceeds, for example, as follows:
Man stellt eine Lösung von Soda in Wasser her (15 bis 20 1 auf 1 kg Baumwolle) und läßt während einer Dauer von 5 Minuten einen Strom von Ozon oder ozonisierter Luft hindurchgehen, hierauf bringt man die Baumwolle in die ozonisierte kaustische Sodalösung, läßt weiter während etwa 30 Minuten Ozon hindurchströmen und hält während der ganzen Zeit die Masse in Bewegung. Dann unterbricht man die Ozonzuführung und kocht das Ganze ungefähr 30 Minuten lang.A solution of soda in water is prepared (15 to 20 liters per 1 kg of cotton) and leaves a stream of ozone or ozonated air for a period of 5 minutes go through, then put the cotton in the ozonated caustic soda solution, lets ozone flow through for about 30 minutes and keeps the mass in motion the whole time. then interrupt the ozone supply and cook the whole thing for about 30 minutes.
Die. so vorbereitete Baumwolle wird noch gewaschen und getrocknet. Sie ist dann fertig für die Auflösung zwecks Herstellung künstlicher Seide.The. Cotton prepared in this way is washed and dried. She is then ready for dissolving for the purpose of making artificial silk.
