Description

Verfahren zum Wasserabstoßendmachen von Textilgut, Leder, Pelzen, Papier und Cellulosehydratfolien Es wurde gefunden, daß man Textilmaterialien aus Wolle, Baumwolle, Cellulosehydratzellwolle, Seide, Cellulosehydratkunstseide in Flocken-, Faden-, Strang-oder Gespinstform, Papier, Cellulosehydratfolien, Leder, Pelzwerk in der Weise wasserabstoßend machen kann, daß man diese Materialien mit Lösungen höhermolekularer Ketene tränkt, trocknet und sie anschließend einer Wärmenachbehandlung bei höherer Temperatur unterwirft.Process for making textile goods, leather, fur, Paper and cellulose hydrate films It has been found that textile materials can be made from Wool, cotton, cellulose hydrate cellulose, silk, cellulose hydrate artificial silk in Flake, thread, strand or web form, paper, cellulose hydrate films, leather, Fur can be made water-repellent in such a way that you can use these materials Solutions of higher molecular weight ketenes soaks, dries them and then a heat treatment submits at higher temperature.

Die erfindungsgemäß zu verwendenden Ketene sind nach dem Verfahren des Patentes '748 98o durch Behandlung höliermolekularer Carbonsäurehalogenide mit starken tertiären Basen erhältlich. Ferner kann man diese Ketene jedoch auch durch Behandlung höhermolekularer a - Bromcarbonsäurebromide mit Zink erhalten. Als höherrnolekulare Ketene werden erfindungsgemäß solche Ketene verwendet, die wenigstens sechs Kohlenstoffatome im Molekül enthalten, z. B. das Butylketen, das Caprylketen, das Laurylketen, das Cetylketen, Ketene, die sich von der Montansäure, den Naphthensäuren, von kernalkylierten Arylcarbonsäuren u. dgl. ableiten. Dabei können die Kohlenwasserstoffreste der Ketene auch Heteroatome oder Heteroatomgruppen, wie z. B. Sauerstoff, Schwefel u. dgl., enthalten.The ketenes to be used according to the invention can be obtained by the process of the ' 748,980 patent by treating higher molecular weight carboxylic acid halides with strong tertiary bases. Furthermore, you can also by treating a higher molecular weight these ketenes, however - get Bromcarbonsäurebromide with zinc. According to the invention, the higher molecular weight ketenes used are those which contain at least six carbon atoms in the molecule, e.g. B. butyl ketene, capryl ketene, lauryl ketene, cetyl ketene, ketenes which are derived from montanic acid, naphthenic acids, from ring alkylated aryl carboxylic acids and the like. The hydrocarbon radicals of the ketenes can also have heteroatoms or heteroatom groups, such as. B. Oxygen, sulfur and the like. Contain.

Die Anwendung dieser Ketene erfolgt im einzelnen in der Weise, daß man die Ketene in organischen Lösungsmitteln, wie beispielsweise Benzin, Schwefelkohlenstoff, Tetrachlorkohlenstoff u. dgl., löst und mit diesen Lösungen die zu imprägnierenden Materialien zunächst tränkt. Man kann, sofern die Herstellung der Ketene in Gegenwart von Lösungsmitteln vor sich geht, unter Umständen auch die dabei erhältlichen Lösungen der Ketene unmittelbar verwenden, also unter Unigehung der vorherigen Isolierung der Ketene. Es werden für die Tränkung, je nach der Art des anzuwendenden Ketens, Lösungen von etwa 0,5 bis 8 "/" in der Regel Lösungen von i bis 3 01" angewendet. Nach der Tränkung und Entfernung des Lösungsmittels werden die Materialien einer Wärinebehandlung bei etwa iio bis i2o' unterworfen. Die Materialien sind nach dieser Behandlung wasserabstoßend. Beispiele i. Man stellt eine 20/,ige Lösung von Cetylketen in Benzin her. Mit dieser Lösung behandelt man Kunstseidesatin während 2o bis 30 Minuten. Der CeHulosehydratkunstseidesatin wird danach aus der Lösung herausgenommen, abgepreßt, unter Wiedergewinnung des Lösungsmittels vorgetrocknet und sodann bei iio' einer Wärmebehandlung unterworfen. Durch diese Behandlung wird die Kunstseide wasserabstoßend. Gegenüber Fettextraktionsmitteln und Seifenwäsche ist der Effekt stabil. Eine Faserschädigung tritt nicht ein.These ketenes are used in detail in such a way that the ketenes are dissolved in organic solvents such as gasoline, carbon disulfide, carbon tetrachloride and the like, and the materials to be impregnated are first impregnated with these solutions. If the ketenes are prepared in the presence of solvents, it is possible under certain circumstances to use the solutions of the ketenes obtainable in this process directly, that is to say without going through the previous isolation of the ketenes. For the impregnation, depending on the type of ketene to be used, solutions of about 0.5 to 8 "/", as a rule solutions of 1 to 3 01 ", are used. After the impregnation and removal of the solvent, the materials are subjected to a heat treatment The materials are water-repellent after this treatment. EXAMPLES 1. A 20% solution of cetylketene in gasoline is prepared. This solution is treated with rayon satin for 20 to 30 minutes The solution is taken out, pressed off, predried with recovery of the solvent and then subjected to a heat treatment at iio '. This treatment makes the rayon water-repellent. The effect is stable to fat extraction agents and soap washing. There is no fiber damage.

2. Ein Wollstoff wird durch Besprengen mit einer 50/,igen Benzinlösung eines Ketengemisches, welches aus Kokosölfettsäuren erhalten wurde, durchtränkt. Nach Entfernung des Lösungsmittels wird der Wollstoff bei iio' einer Wärmebehandlung unterworfen. Nach dieser Behandlung besitzt der Stoff wasserabstoßende Eigenschaften.2. A woolen fabric is made by sprinkling it with a 50% gasoline solution a ketene mixture obtained from coconut oil fatty acids. After the solvent has been removed, the woolen material undergoes a heat treatment subject. After this treatment, the fabric has water-repellent properties.
