Description
Verfahren zum feuersicheren Imprägnieren von tierischen Fasern Der Erfindung liegt die Aufgabe zugrunde, tierische Fasern durch Imprägnierung feuersicher zu machen. Sie ist insbesondere auf die Feuerfestmachung von Federn, namentlich Gänsefedern, gerichtet, welche zur Herstellung künstlicher Christbäume Verwendung finden, denn bei solchen Christbäumen ist die Gefahr einer Entzündung wegen der brennenden Kerzen besonders groß. Auch sind die Folgen eines brennenden Christbaums wegen der üblicherweise in seiner Nähe befindlichen Kinder besonders schwerwiegend.Method for the fire-safe impregnation of animal fibers The object of the invention is to make animal fibers fire-safe by impregnation. It is aimed in particular at making feathers fireproof, namely goose feathers, which are used for the production of artificial Christmas trees, because with such Christmas trees the risk of ignition due to the burning candles is particularly great. The consequences of a burning Christmas tree because of the usually located in its vicinity children are particularly serious.
-Es ist bekannt, pflanzliche Gewebe mit Hilfe von Wasserglas unentflarnrabar zu machen. Die pflanzlichen Gewebe saugen sich bei der Imprägnierung mit der wäßrigen Wasserglaslösung voll. Beim Verdunsten -des Wassers bildet sich dann in den Zwischenräumen, also zwischen den einzelnen Fasern, ein Silicatgerüst mit Einschlüssen von Kristallwasser. Wenn derart behandeltes Gewebe über seine Entflammungstemperatur gebracht wird, dann wird zunächst das eingeschlossene Kristallwasser ausgetrieben. Dabei findet ein Aufblähen des Silicatgerüstes statt, mit der Wirkung, daß gewissermaßen ein Silicatpanzer um das Gewebe herum und durch das Gewebe hindurch entsteht. Dieser Panzer hindert den Zutritt des Luftsauerstoffs und macht auf diese Weise eine Entflammung unmöglich. Diese Imprägnierung hat sich namentlich bei Holz bewährt. Sie ist aber auf tierische Fasern, welche im wesentlichen aus einem Keratingerüst bestehen, nicht anwendbar, da tierische Gewebe nicht wie die auf Cellulosebasis aufgebauten pflanzlichen Gewebe aufsaugfähig sind. Es kann daher durch eine einfache Wasserglasbehandlung der oben beschriebene, bei Pflanzenfasern erreichbare Effekt bei tierischen Fasern nicht erzielt werden. Hinzu kommt, daß ein gewöhnlicher Wasserglasüberzug leicht abblättert und auch das Aussehen beeinträchtigt, was namentlich .bei Gänsefedern, die zur Erzeugung künstlicher Christbäume bestimmt sind, besonders nachteilig ist. It is known to use water glass to make vegetable tissues non-inflatable. The plant tissue soaks up during the impregnation with the aqueous waterglass solution. Upon evaporation - of the water then forms in the interstices, ie between the individual fibers, a silicate framework with inclusions of crystal water. When tissue treated in this way is brought above its inflammation temperature, the enclosed water of crystallization is first expelled. This causes the silicate framework to expand, with the effect that, to a certain extent, a silicate armor is created around the tissue and through the tissue. This armor prevents the entry of oxygen from the air and in this way makes it impossible to ignite. This impregnation has proven itself particularly with wood. However, it cannot be applied to animal fibers, which essentially consist of a keratin structure, since animal tissues are not absorbent like cellulose-based plant tissues. The above-described effect which can be achieved with vegetable fibers cannot therefore be achieved with animal fibers by a simple water glass treatment. In addition, an ordinary water-glass coating peels off easily and also affects the appearance, which is particularly disadvantageous in the case of goose feathers, which are intended for the production of artificial Christmas trees.
Es sind außer Wasserglas noch andere flammenwidrige Stoffe bekannt. Deren Wirkung beruht auf ' der Abspaltung inerter Gase, z. B. Ammoniak,.In addition to water glass, other flame-retardant substances are known. Their effect is based on the elimination of inert gases, e.g. B. ammonia ,.
Kohlendioxyd und ähnliche. Es müssen aber diese Stoffe im vorliegenden Fall aus der Betrachtung ausscheiden, weil ihre Wirkung sehr begrenzt ist, die Feuersicherheit also einige Zeit nach der Imprägnierung nicht mehr gewährleistet ist. Gerade bei künstlichen Christbäumen kommt es aber auf dieDauerhaftigkeit der Imprägnierungswirkung an.Carbon dioxide and the like. But there must be these substances in the present Case out of consideration because its effect is very limited, fire safety So some time after the impregnation is no longer guaranteed. Just at artificial Christmas trees, however, it depends on the durability of the impregnation effect at.
Ferner ist ein flammenschützender Anstrich unter dem Namen Locron bekanntgeworden. Dabei handelt es sich um ein Produkt auf der Basis von Harnstoff-Formaldehyd-Kondensaten der A-Stufe (flüssige Kondensationsform). Durch Zugabe von Formaldehyd und Einwirkung von Wärme wird auf einem mit diesem Stoff bestrichenen Gewebe die C-Stufe (feste, unlösliche Kondensationsform) erzeugt. Die Feuerschutzwirkung beruht auf der Zersetzung unter Bildung von Kohlensäure, ,Ammoniak und Formalde'hydgas beim Verbrennen. Diese Art der Feuerfestmachung scheidet für den vorgesehenen Zweck ebenfalls aus, weil das Anwendungsverfahren zu umständlich, mithin zu teuer ist. Die Gestehungskosten der tierischen Fasern, z. B. der Gänsefedern, dürfen aber durch die Feuerschutzimprägnierung nicht wesentlich erhöht werden. Außerdem hat diese Imprägnierung den Nachteil, daß die Fasern einen Kauritleimüberzug erhalten, da es sich bei dem Anstrichmittel eigentlich um Kaurit.lei.m handelt. Durch einen solchen Überzug leidet aber das Aussehen der Christbaumzweige so stark, daß diese nicht mehr brauchbar sind.There is also a flame retardant paint under the name Locron known. This is a product based on urea-formaldehyde condensates the A stage (liquid condensation form). By adding formaldehyde and acting heat is applied to a fabric coated with this substance, the C-level (firm, insoluble condensation form). The fire protection effect is based on the decomposition with the formation of carbonic acid, ammonia and formaldehyde gas during combustion. These Type of refractory is also ruled out for the intended purpose because the application process is too cumbersome and therefore too expensive. The prime cost the animal fibers, e.g. B. the goose feathers, but may through the fire protection impregnation cannot be increased significantly. In addition, this impregnation has the disadvantage that the fibers receive a Kaurit glue coating, as it is actually the case with the paint is about Kaurit.lei.m. Such a coating, however, suffers from the appearance of the Christmas tree branches so strong that they can no longer be used.
Es hat sich nun überraschenderweise gezeigt, daß das Wasserglasverfahren so modifiziert werden kann, daß es zur feuersicheren Imprägnierung tierischer Gewebe, z. B. zur Imprägnierung von zur Bildung künstlicher Christbäume auf Drähten aufgedrehter Gänsefedern, mit Vorteil geeignet ist. Es wurde gefunden, daß auf der Faser das Wasserglas mit Schwermetallsalz zu Metallsilicat und Metallhydroxyd umgesetzt und durch Beifügung eines entsprechenden Netzmittels ein festhaftender Wasserglasfilm gebildet werden kann, der mit -%fetallsilicat- und Metallhydroxydeinschlüssen versehen ist und der eine hervorragendflammenwidrige Wirkung auf das Eiweißgewebe ausübt. Ein auf diese Weise imprägnierter Kunstohristbaumzweig kann mehrere Minuten lang in eine Flamme gehalten werden, ohne daß Entflammung eintritt. Es zeigt sich dabei, wie Versuche ergaben, nicht einmal ein Zusammensch,moren des Zweiges. Die Imprägnierung gemäß der Erfindung bietet den weiteren Vorteil, daß das Aussehen des Zweiges in keiner Weise leidet. Das erfindungsgemäße Verfahren kann derart angewendet werden, daß tierische Fasern, z. B. die auf einen Draht aufgedrehten Federn, also die fertigen Christbaumzweige, in der Lösung eines Netzmittels, welchem ein Schwermetallsalz zugefügt ist, gebadet, dann in eine mäßig konzentrierte Wasserglaslösung getaucht und daraufhin getrocknet werden. Es kann beispielsweise derart vorgegangen werden, daß die Zweige in ein Bad gebracht werden, welches aus einer etwa i- Abis 3%-igen Lösung eines Netzmittels, z. B. eines Fettalkoholsulfonates, und einer 6- bis 8°/oigen Lösung von Zinn-(11)-chlorid besteht. In diesem Bad bleiben die Zweige etwa 2o Minuten lang, dann werden sie entnommen, abgeschüttelt und kurzzeitig, z. B. i Minute lang, in etwa halbkonzentrierte Wasserglaslösung getaucht. Hiernach werden die Zweige abgeschüttelt und in geeigneten Anlagen zum Trocknen aufgehängt. Es empfiehlt sich, die Zinn-(11)-chloridlösung mit destilliertem Wasser anzusetzen. Für die Wasserglaslösung kann das im Handel käufliche Wasserglas verwendet und mit der gleichen bis doppelten Menge Wasser verdünnt werden.It has now been shown, surprisingly, that the water glass process can be modified so that it can be used for the fire-proof impregnation of animal tissue, z. B. for the impregnation of twisted to the formation of artificial Christmas trees on wires Goose feathers, is suitable with advantage. It was found that on the fiber Water glass with heavy metal salt converted to metal silicate and metal hydroxide and by adding a suitable wetting agent a firmly adhering waterglass film which is provided with -% metal silicate and metal hydroxide inclusions and which has an excellent flame retardant effect on the protein tissue. An artificial ear tree branch impregnated in this way can last for several minutes be held in a flame without igniting. It shows as tests have shown, not even a togetherness, mor of the branch. The impregnation according to the invention has the further advantage that the appearance of the branch in in no way suffers. The method according to the invention can be applied in such a way that animal fibers, e.g. B. the springs twisted on a wire, so the finished Christmas tree branches in a solution of a wetting agent, which is a heavy metal salt is added, bathed, then immersed in a moderately concentrated waterglass solution and then dried. For example, you can proceed as follows: that the branches are brought into a bath, which consists of an approximately i-Abis 3% strength Solution of a wetting agent, e.g. B. a fatty alcohol sulfonate, and a 6- to 8% Solution of tin (11) chloride. The branches remain in this bath for about 20 minutes long, then they are removed, shaken off and briefly, e.g. B. for i minute, immersed in about half-concentrated water glass solution. After that the branches become shaken off and hung to dry in suitable facilities. It is advisable, prepare the tin (11) chloride solution with distilled water. For the water glass solution the commercially available water glass can be used and with the same to double Amount of water to be diluted.
Außer den beim oben angegebenen Ausführungsbeispiel erwähnten Sulfonaten sind selbstverständl@ich auch andere Netzmittel verwendbar. Es kommen beispielsweise in Betracht: Alkaliseifen aller Art, wie Stearate, Oleate, Phthalate, Linoleate, Laurate, Naphthenate; Wachsseifen, welche dadurch gewonnen werden, daß verseifbare Wachse mit Alkali total oder partiell verseift werden; Harzseifen, die durch Verseifung von Colophonium erzeugt werden; Gallensäurepräparate, wie sie sich unter den Handelsbezeichnungen Curacit, Sabunit u. dgl. im Verkehr befinden; alkylnaphthalinsulfonsaure Salze, wie sie unter den Warenbezeichnungen Nekal A, Nekal AEM bekannt sind; Sulfonate aller Art z. B. Türkischrotöl; Fettalkoholsulfonate usw.; organische Basen, beispielsweise Triäthanolamin.Except for the sulfonates mentioned in the above-mentioned embodiment Of course, other wetting agents can also be used. There come, for example Consideration: alkali soaps of all kinds, such as stearates, oleates, phthalates, linoleates, Laurates, naphthenates; Wax soaps, which are obtained by being saponifiable Waxes are totally or partially saponified with alkali; Resin soaps made by saponification produced from rosin; Bile acid preparations, as they come under the trade names Curacit, Sabunit and the like are in traffic; alkylnaphthalenesulfonic acid salts, as they are known under the trade names Nekal A, Nekal AEM; Sulfonates of all kinds z. B. Turkish red oil; Fatty alcohol sulfonates, etc .; organic bases, for example Triethanolamine.
Es sind alle Schwermetallsalze brauchbar, welche in Wasser oder anderen geeigneten Solventien löslich sind und welche das Metall im Anion oder Kation enthalten. Es kann beispielsweise das obenerwähnte Zinn-(II) -chlorid durch Pinksalz (N N4)2 (Sn C1)6 oder durch Präpariersalz Na4 [Sn (O H) ] s ersetzt werden. Auch Zinn-(I1)-sulfat hat sich bevvährt.All heavy metal salts can be used, which are in water or others suitable solvents are soluble and which contain the metal in the anion or cation. For example, the above-mentioned tin (II) chloride can be replaced by pink salt (N N4) 2 (Sn C1) 6 or by the preparation salt Na4 [Sn (O H)] s. Also tin (I1) sulfate has proven itself.
Es ist nicht nur das unter der Bezeichnung Wasserglas üblicherweise verstandene Natronwasserglas brauchbar. Es kann auch mit Kaliwasserglas gearbeitet werden.It is not just what is commonly known as water glass understood soda water glass useful. Potash water glass can also be used will.
Bei der Verwendung der Seifen ist darauf zu achten, daß nicht ein solches Schwermetallsalz verwendet wird, das durch Umsetzung mit der Seife unlösliche Schwermetallseifen bildet.When using the soaps, care should be taken that there are no such heavy metal salt is used, which is insoluble by reaction with the soap Forms heavy metal soaps.
Es ist ein zusätzlicher Entflammungsschutz dadurch erreichbar, daß auf die Federn Glaspulver aufgebracht, vorzugsweise aufgestäubt wird, welches die Bildung eines Silicatüherzuges bewirkt.Additional flame protection can be achieved in that applied to the springs glass powder, preferably dusted, which the Causes the formation of a train of silicates.
Die Erfindung ist bei tierischen Fasern aller Art anwendbar. Wegen der bereits erwähnten erhöhten Brand- und Schadensgefahr ist sie aber für aus Tierfedern, vornehmlich Gänsefedern erzeugten künstlichen Christbaum- oder Dekorationsschmuck u. dgl. besonders bedeutsam.The invention is applicable to all types of animal fibers. Because the already mentioned increased risk of fire and damage it is for off Animal feathers, mainly goose feathers produced artificial Christmas tree or decorative decorations and the like particularly significant.
