Description
Verfahren zum Feuerfestmachen von Geweben Die vorliegende Erfindung betrifft ein Verfahren, üm Gewebe gegen Leichtentflammbarkeit zu schützen und ein besonders gutes Haften des Imprägniermittels auf dem Gewebe zu gewährleisten. Außerdem kennzeichnet sich das neue Imprägniermittel dadurch, daß seine Rohmaterialien sämtlich im Inlande erhältlich. sind.Methods of Fireproofing Fabrics The present invention relates to a method to protect fabric against high flammability and a to ensure particularly good adhesion of the impregnating agent to the fabric. aside from that The new impregnation agent is characterized by the fact that its raw materials are all available domestically. are.
Das neue Feuerschutzmittel besteht aus Ammoniumsulfat, Ammoniumbiphosphat und Bicarbonat, vorzugsweise Natriiunbicarbonat, wobei das Bicarbonat zweckmäßig in Mengen bis zu io%, bezogen auf das eigentliche Feuerschutzmittel, angewendet wird.The new fire retardant consists of ammonium sulfate, ammonium biphosphate and bicarbonate, preferably sodium bicarbonate, the bicarbonate being useful Used in amounts of up to 10%, based on the actual fire protection agent will.
Das neue Mittel, das in wäßriger Uisung angewandt wird, löst sich !in Wasser leicht auf. Bicarbonat als solches ist als Feuerschutzmittel bereits vorgeschlagen worden, übt je- doch selbst keine beachtliche Feuerschutzwirkung aus.The new remedy, which is used in an aqueous solution, dissolves easily in water. Bicarbonate as such has already been proposed as a fire protection agent, but it does not itself have any notable fire protection effect.
Es ist auch bereits vorgeschlagen worden, mit Feuerschutzmitteln imprägnierte Gewebe nachträglich mit Natriumbicarbonat zu behandeln oder statt dessen nach der eigentlichen Imprägnierung Kohlensäure auf die Gewebe einwirken zu lassen. Abgesehen davon, daß hierbei die Auflösungsgeschwindigkeit für das Imprägniergemisch ein Vielfaches von derjenigen bei sofortigem Zusatz von Natriumbicarbonat beträgt, haben diese letzteren Verfahren den Nachteil, daß Gewebe von mangelhafter Griffigkeit und fleckigem Aussehen entstehen. Es ist ferner für die Holzimprägnierung die Mitverwendung von Natriumbicarb:onat bereits vorgeschlagen worden. Abgesehen davon, daß Holzianprägnierung und Gewebeimprägnierung nicht miteinander vergleichbar sind, wird die Verwendung von Natriumbicarbonat in diesem Falle nur in Verbindung mit Natriumchlorid als eigentlichem Imprägniermittel genannt, einer Verbindung also, die für die GewebeimprägnIerung überhaupt nicht in Frage kommt.It has also been proposed to be impregnated with fire retardants Treat tissue subsequently with sodium bicarbonate or, instead, after actual impregnation carbonic acid to act on the fabric. Apart from that from the fact that in this case the rate of dissolution for the impregnation mixture is a multiple of those with the immediate addition of sodium bicarbonate, have this the latter method has the disadvantage that fabrics of poor grip and stained Appearance arise. It is also used for impregnation of wood Sodium bicarb: onate has already been proposed. Apart from that wood impregnation and fabric impregnation are not comparable with each other, the use is of sodium bicarbonate in this case only in connection with sodium chloride as the actual Called impregnation agent, a compound that is used for fabric impregnation is out of the question at all.
Es ist endlich schon Borsäure oder auch Borax im Gemisch mit an sich bekannten Feuerschutzmitteln, z. B. mit Kaliumbicarbonat, zum Feuerfestmachen von Geweben vorgeschlagen worden. Diese bekannten Feuerschutzmittel ;sind jedoch in ihrer Wirkung dem erfindungsgemäß verwendeten Feuerschutzmittel wesentlich unterlegen.It is finally boric acid or borax in a mixture with itself known fire protection agents, e.g. B. with potassium bicarbonate, for refractory of Fabrics have been suggested. These well-known fire retardants; are, however, in their effect is substantially inferior to the fire retardant used according to the invention.
Anderen bekannten Imprägniermitteln zum Feuerfestmachen von Geweben, wie Gemischen aus Ammoniumsulfat, Ammoniumphosphat und Ammoniumcarbonat, aus Ammoniumsulfat und Kaliumbicarbonat oder aus Magnesiumsulfat. und Kaliumbicarbonat, ist das neue Feuerfestimprägniermittei bei seiner Anwendung auf Gewebe hinsichtlich seiner Feuerschutzwirkung erheblich überlegen.Other known impregnating agents for making fabrics fireproof, such as mixtures of ammonium sulfate, ammonium phosphate and ammonium carbonate, from ammonium sulfate and potassium bicarbonate or from magnesium sulfate. and potassium bicarbonate the new refractory impregnating agent in its application to fabrics as to its Considerably superior to fire protection.
Beispiel Gewebe werden mindestens 5 Min-tw lang in eine Lösung von -68 Teilen Ammoniumsulfat 30 - Ammoniumbiphosphat und 2 - Natriumbicarbönat in 500 - Wasser getaucht, oder die Gewebe werden mit dieser Lösung bis zur völligen Durchfeuchtung auf beiden Seiten bespritzt. Sie werden alsdann 1g abgequetscht und getrocknet; erforderlichenfalls können sie anschließend noch geilättet oder gerollt werden.Example tissues are immersed in a solution of at least 5 min-tw -68 parts of ammonium sulfate 30 - ammonium biphosphate and 2 - sodium bicarbonate in 500 - Submerged in water, or the tissues are soaked with this solution until completely moistened splattered on both sides. You are then squeezed off 1 g and dried; if necessary, they can then be smoothed or rolled.
