Description

Verfahren zum Überziehen von Fellen durch Aufdampfen von Metallen im Hochvakuum Die Erfindung betrifft ein Verfahren zum Aufbringen von festhaftenden Metallschichten auf tierische Felle durch Niederschlagen von Metalldampf im Hochvakuum.Process for covering skins by vapor deposition of metals in a high vacuum The invention relates to a method for applying firmly adhering Metal layers on animal skins through the deposition of metal vapor in a high vacuum.

Es ist bekannt, auf dem Wege der Abscheidung von. Metalldampf aus dem Hochvakuum Werkstoffe aller Art mit einer dünnen festhaftenden Metallschicht zu überziehen, ein Verfahren, das beispielsweise für die Metallisieru.ng von Kunststoffen, aber auch von Textilien bereits weitgehend Anwendung findet. Während solche Metallschichten auf vollsynthetischen Fasern bzw. Flächengebilden daraus im allgemeinen befriedigend festhaften, bereitet die Fixierung von Metallüberzügen auf Baumwolle oder Wolle so erhebliche Schwierigkeiten, daß sich in vielen Fällen keine gebrauchsfähigen metallisierten Produkte ergeben.It is known by the way of deposition. Metal vapor off the high vacuum all kinds of materials with a thin, firmly adhering metal layer to be coated, a process that is used, for example, for the metallization of plastics, but is already widely used by textiles. While such metal layers generally satisfactory on fully synthetic fibers or fabrics made from them Adhere firmly, prepares the fixation of metal coatings on cotton or wool difficulties so great that in many cases there are no usable ones metallized products result.

Neuerdings hat auch die Metallisierung von tierischen Fellen, Pelzen u. dgl. Interesse gewonnen, wobei sich jedoch gezeigt hat, daß diese Aufgabe mit der üblichen Bedampfungstechnik nicht vollkommen gelöst werden kann, da .hier die Haftungsschwierigkeiten womöglich noch größer sind als -beispielsweise bei Wolle.Lately also has the metallization of animal skins, furs and the like. Interest gained, but it has been shown that this task with the usual vaporization technology can not be completely solved because .Hier the Adhesion difficulties are possibly even greater than, for example, with wool.

Es ist ein Verfahren zur Veredlung von Fellen bekannt, nach dem die Haarseiten der Felle im luftverdünnten Raum der Einwirkung von zur Verdampfung gebrachten festen anorganischen Stoffen, z. B. Metallen, unterworfen und dadurch angefärbt werden.There is a known process for the finishing of skins, according to which the The hairsides of the skins in the air-thinned space of the action of evaporation solid inorganic substances, e.g. B. metals, subjected and thereby stained will.

Die Behandlung der Felle im luftverdünnten Raum kann auch in Gegenwart von hygroskopischen Stoffei: erfolgen; es werden also in die Vakuumanlage Stoffe eingebracht, die das austretende Wasser aufnehmen sollen.The treatment of the skins in the air-diluted room can also be done in the presence of hygroscopic substances; So there are substances in the vacuum system introduced to absorb the escaping water.

Weitenhin ist eine gegen Strahlung und Abstrahlung schützende Kleidung mit einer durch Kathodenzerstäubung oder Vakuumaufdampfung aufgebrachten dünnen Metallschicht bekannt, bei der unter der Metallschicht ein unmittelbar vor der Kondensation der Metalle künstlich durch Vakuumaufdampfung oder hathodenzerstäubung erzeugter, hafterhöhender Zwischenbelag eines chemisch beständigen, wasserunlöslichen Oxyds liegt.Weitenhin is clothing that protects against radiation and radiation with a thin one applied by sputtering or vacuum evaporation Metal layer known, in which under the metal layer a immediately before the condensation the metals artificially produced by vacuum evaporation or hathodic atomization, Adhesion-increasing intermediate layer of a chemically resistant, water-insoluble oxide lies.

Es wurde nun ein neues Verfahren zum Überziehen von tierischen Fellen durch Aufdampfen von Metallen im Hochvakuum gefunden. Auch bei der Durchführung dieses Verfahrens wird vor dem Aufdampfen der äußeren Metallschicht eine homogene hafterhöhende Zwischenschicht durch Kathodenzerstäubung aufgebracht. Im Gegensatz zu dem Verfahren, nach dem hygroskopische Stoffe eingebracht werden, wird bei dem neuen Verfahren das Material hydrophob gemacht, um das Wasser in dem Material zu belassen und dadurch die Flexibilität des Materials aufrechtzuerhalten. Nicht Oxyde, sondern bestimmte Metalle kommen hier für die Zwischenschicht in Frage. Das neue Verfahren ist dadurch gekennzeichnet, daß für die Zwischenschicht ein Metall der Ib-Gruppe des Periodischen Systems der Elemente, besonders Ag oder Cu, verwendet wird.There has now been a new method of covering animal pelts found by vapor deposition of metals in a high vacuum. Also in the implementation this process becomes homogeneous before the external metal layer is vapor deposited Adhesion-increasing intermediate layer applied by cathode sputtering. In contrast the process by which hygroscopic substances are introduced is the new process made the material hydrophobic to remove the water in the material and thereby maintaining the flexibility of the material. Not oxides, rather, certain metals come into question here for the intermediate layer. The new The method is characterized in that a metal is used for the intermediate layer Ib group of the Periodic Table of the Elements, especially Ag or Cu, is used will.

Die homogene Zwischenschicht gemäß der Erfindung bewirkt eine rasche Verschließung der Grundmaterial-Oberfläche und macht diese im Hochvakuum bearbeitbar, ohne daß der Bedampfungseffekt gestört werden. kann.The homogeneous intermediate layer according to the invention causes a rapid one Sealing of the base material surface and makes it workable in a high vacuum, without the steaming effect being disturbed. can.

Für die Zwecke der Erfindung kann man sich an sich bekannter Imprägnierungsmittel bedienen, die hydrophobierend wirken. Hierfür kommen insbesondere als Textilhilfsmittel bekannte Kunstharze in Betracht; unter diesen haben sich besonders Silikone in Form von Lösungen oder Dispersionen bewährt. Selbstverständlich müssen solche Imprägn.ierungsmittel ausgewählt werden, die nicht zu einer Versprödung des Haares führen.For the purposes of the invention, known impregnating agents can be used that have a hydrophobic effect. These are used in particular as textile auxiliaries known synthetic resins into consideration; Silicones are particularly popular among these proven of solutions or dispersions. It goes without saying that such impregnation agents must be used selected that do not cause hair to become brittle.
