An die Flammfestausrüstung von Cellulosetextilien werden durch das steigende Sicherheitsbedürfnis immer höhere Anforderungen gestellt, so hinsichtlich verminderter Entflammbarkeit, besserer Haltbarkeit nach der Chemischreinigung und der Naßwäsche» Außerdem soll die Ausrüstung so gesteuert werden, daß sie die Beißfestigkeit und Scheuerfestigkeit möglichst wenig vermindert.The flame retardant finish of cellulose textiles is made by the increasing need for security made ever higher demands, so in terms of reduced flammability, better Shelf life after dry cleaning and wet washing »In addition the equipment should be controlled in such a way that it increases the bite resistance and abrasion resistance reduced as little as possible.
Gegenstand des Hauptpatentes . ... .., (Patentanmeldung P 14 69 353.9) ist ein Verfahren zum Flammfestmachen von Cellulosefasern mit Phosphorverbindungen, die an Phosphor gebundene Methylolgruppen enthalten, wobei das Fasergut mit wäßrigen Lösungen der öligen und neutralen Umsetzungsprodukte aus 1 Mol Epihalogenhydrin und etwa 2 Mol Tri-hydroxymethyl-phosphin imprägniert und anschließend mit Ammoniak behandelt wird.Subject of the main patent. ... .., (Patent Application P 14 69 353.9) is a method for flameproofing cellulosic fibers with phosphorus compounds, the phosphorus bound methylol, wherein the fiber material with aqueous solutions of the oily and neutral reaction products of 1 mole of epihalohydrin and about 2 moles of tri -hydroxymethyl-phosphine is impregnated and then treated with ammonia.
Die nach diesem Verfahren erhaltenen Flammfestausrüstungen entsprechen den Prüfbedingungen laut DIN-Vorschrift 53 906 und vielen Erfordernissen der Praxis. *The flame retardant finishes obtained by this method correspond the test conditions according to DIN regulation 53 906 and many Practical requirements. *
In weiterer Ausgestaltung des Verfahrens zum Flammfestmachen von Cellulosefasern gemäß Patent , ...... (PatentanmeldungIn a further embodiment of the method for making flame resistant Cellulose fibers according to patent, ...... (patent application
P 14 69 353.9) wurde nun gefunden, daß Fasergut mit wäßrigen Lösungen der öligen und neutralen Umsetzungsprodukte aus 1 Mol Epihalogenhydrin und etwa 2 Mol Trihydroxymethylphosphxn unter Zusatz von Trisaziridinyl-phosphinoxid imprägniert und anschlieskibiä^ wird.P 14 69 353.9) has now been found that fiber material with aqueous solutions of the oily and neutral reaction products of 1 mol Epihalohydrin and about 2 mol Trihydroxymethylphosphxn with the addition of Trisaziridinylphosphinoxid and anschlieskibiä ^ will.

Das Verfahren des Hauptpatentes wird in der Weise ausgeführt, daß das Fasergut oder die Gewebe mit einer etwa 5 bis 80 %igen, vorzugsweise 20 bis 40 %igen wäßrigen Lösung des Umsetzungsproduktes a*is Epihalogenhydrin und Tris-hydroxymethyl-phosphin in üblicher Weise, Z9 B. auf dem Foulard, imprägniert wird. Man wählt hierbei Aöquetscheffekte von etwa 50 bis etwa 100 % Flüssigkeitsaufnahme. Anschließend wird das Fasergut im allgemeinen in üblicher Weise bei etwa 40 bis 130°C getrocknet, wobei man Restfeuchtigkeiten von etwa 3 bis etwa 30 %, vorzugsweise 7 bis 20 %, "erreicht.The method of the main patent is carried out in such a way that the fiber material or the fabric with an approximately 5 to 80%, preferably 20 to 40%, aqueous solution of the reaction product a * is epihalohydrin and tris-hydroxymethyl-phosphine in the usual way, Z 9 B. on the foulard, is impregnated. A squeeze effect of about 50 to about 100 % liquid absorption is selected here. The fiber material is then dried in the usual way at about 40 to 130 ° C., residual moisture levels of about 3 to about 30%, preferably 7 to 20%, being achieved.
Bsi dem gemäß <ler vorliegenden Erfindung anzuwendenden Verfahren werden der Imprägnierflotte, wie sie vorstehend und im Hauptp >v ent beschrieben ist, etwa 20 bis 200 g/l Trisaziridinylpfcjsphinoxid zugesetzt. Damit wird eine Verbesserung des Flamm-S-:nutzes erreicht, auch gegenüber längerer Einwirkung von größeren Flammen. Dabei werden die Gewebe nur unwesentlich in ihren technologischen Eigenschaften geschädigt. Außerdem bleibt der textile Griff und die Möglichkeit von Nachbehandlungen (z. B. Hydrophobieren, ölabweisende Ausrüstung u„ a.) erhalten.According to the method to be used according to the present invention, about 20 to 200 g / l trisaziridinylphosphine oxide are added to the impregnation liquor, as described above and in the main paragraph. In order to improve the flame is S:-interest achieved even over prolonged exposure to larger flames. The technological properties of the tissue are only insignificantly damaged. In addition, the textile feel and the possibility of subsequent treatments (e.g. hydrophobization, oil-repellent finish, etc.) are retained.
Vorteilhaft ist es, das imprägnierte und zwischen 2 Walzen abge-It is advantageous to use the impregnated and coated between 2 rollers
o Quetschte Cellulosefasergut bei 90 bis 120 C zu trocknen, wobei der oben erwähnte Restfeuchtigkeitsgehalt zu beachten ist.o Squeezed cellulose fiber to dry at 90 to 120 C, whereby the above-mentioned residual moisture content must be observed.
Die nachfolgende Wirkung von Ammoniak kann entweder mit Ammoniakgas oder vorteilhaft auch mit wäßrigen Lösungen von etwa 3 bis 12 % von Ammoniak erfolgen. Bei Verwendung von Ammoniaklösungen ist es zweckmäßig, außerdem noch anorganische Neutralsalze, wie Natriumsulfat, Kaliumchlorid, zuzusetzen. Auch bei diesem technologisch besonders einfachen Verfahren, für das lediglich gängige Textilausrüstungsaaschinen erforderlich sind, z. B. ein 2- oder 3-Walzenfoulard, einfache Trocknungsspannrahmen und für die Naßvernetzung Jigger oder Y/aschraaschine, wird eine überraschend-gute Wasch- und Chemischreinigungsbeständigkeit erreicht.The subsequent effect of ammonia can either be with ammonia gas or advantageously also with aqueous solutions of about 3 to 12% of ammonia. When using ammonia solutions it is advisable to also add inorganic neutral salts such as sodium sulfate and potassium chloride. Even with this technologically particularly simple process for which only common textile finishing machines are required, e.g. B. a 2- or 3-roll foulard, simple drying frame and for wet crosslinking Jigger, or Y / aschraaschine, will be a surprisingly good one Wash and dry cleaning resistance achieved.
