Description
Verfahren zur Erhöhung der Widerstandsfähigkeit von Fasern und aus ihnen hergestellten Erzeugnissen gegen die Einwirkung von Mikroorganismen Es ist bekannt, daß Fasern, die mit Phenolen imprägniert sind, weitgehend resistent gegen die Einwirkung von Mikroorganismen sind und daß diese Widerstandsfähigkeit jedoch durch Naßbehandlung verlorengeht. Man hat daher zahlreiche weitere Vorschläge für eine dauerhafte Imprägnierung von Fasermaterialien gegen Mikroorganismen und andere Schädlinge gemacht. Beispielsweise sollen organische Lösungen von Insektiziden auf die Faser aufgebracht und unter Verwendung von Harzen physikalisch fixiert werden. Nach einem anderen Vorschlag soll Baumwolle dadurch bakterizid ausgerüstet werden, daß man sie mit Mitteln behandelt, die mit den Cellulosehydroxylgruppen unmittelbar oder über Hilfsverbindungen reagieren, z. B. durch Verätherung, und darauf die Reaktion herbeiführt. Diese und weitere, im Prinzip ähnliche bekannte Maßnahmen erfordern umständliche Anwendungsmethoden und/oder führen zu einer ungenügenden Imprägnierung.Process for increasing the resistance of fibers and from It is manufactured products against the action of microorganisms known that fibers which are impregnated with phenols are largely resistant to the action of microorganisms and that this resistance, however is lost by wet treatment. There are therefore numerous other suggestions for a permanent impregnation of fiber materials against microorganisms and others Pests made. For example, organic solutions of insecticides are said to be based on the fiber can be applied and physically fixed using resins. According to another proposal, cotton should be given a bactericidal finish, that they are treated with agents directly related to the cellulose hydroxyl groups or react via auxiliary connections, e.g. B. by etherification, and then the reaction brings about. These and other, in principle similar, known measures require cumbersome application methods and / or lead to insufficient impregnation.
Es wurde nun gefunden, daß man Fasern der verschiedensten Art und Herkunft oder auch aus ihnen hergestellte Erzeugnisse, insbesondere Textilien, gegen die Einwirkung von Mikroorganismen auf günstige Weise, mit befriedigendem Erfolg und ohne Schädigung der Fasern widerstandsfähig machen kann, wenn man die Fasern mit substituierten Phenolen imprägniert und, gegebenenfalls nach einer Zwischentrocknung, mit kondensationsfähigen polyfunktionellen nichtkondensierten Verbindungen behandelt, trocknet und mit Hilfe von Katalysatoren bei erhöhter Temperatur die Härtung der kondensationsfähigen Verbindungen herbeiführt.It has now been found that fibers of the most varied types and Origin or products made from them, especially textiles, against the action of microorganisms in a favorable manner, with satisfactory results and without damaging the fibers, you can make them resistant if you use the fibers impregnated with substituted phenols and, if necessary after intermediate drying, treated with condensable polyfunctional non-condensed compounds, dries and with the help of catalysts at elevated temperature the hardening of the brings about condensable compounds.

Fasern oder daraus hergestellte Erzeugnisse, die in der beschriebenen Weise behandelt wurden, behalten ihre Widerstandsfähigkeit gegen Mikroorganismen auch nach mehrfachem Waschen oder Naßbehandeln unverändert bei: Die in dem Beispiel angegebenen Teile sind Gewichtsteile.Fibers or products made therefrom, which are described in the Treated wisely, retain their resistance to microorganisms unchanged even after repeated washing or wet treatment: The one in the example parts given are parts by weight.
Beispiel 10 Teile 2,4,5-Trichlorphenol und 25 Teile Triäthanolamin werden in 1000 Teilen Wasser gelöst. Bei einem Flottenverhältnis 1 : 20 wird Wolle mit dieser Lösung bei Raumtemperatur während 15 Minuten imprägniert, nach einer Trocknung bei 90°C in ein zweites Bad gebracht, das eine Lösung von 4 Teilen Ammoniumnitrat, 80 Teilen Tetramethylolacetylendiharnstoff in 1000 Teilen Wasser enthält.

After a Treatment of 5 minutes at room temperature, the wool is dried at 90 ° C and then condensed at 140 ° C for 10 minutes.
Ein Teil der Wolle wird mit Seifenwasser gewaschen, der andere unmittelbar für die Prüfung verwendet. Beide Proben zeigen nach dem Eingraben in feuchter Gartenerde nach 49 Tagen noch keine Einwirkung der Mikroorganismen. Dagegen zersetzt sich eine Probe, die nur mit Trichlorphenol imprägniert und dann gewaschen worden war, unter sonst gleichen Bedingungen bereits nach 28 Tagen.Part of the wool is washed with soapy water, the other immediately used for testing. Both samples show after being buried in moist garden soil after 49 days there was still no effect of the microorganisms. On the other hand, one decomposes Sample that had just been impregnated with trichlorophenol and then washed under otherwise the same conditions after 28 days.
