Verfahren zur Erhöhung der Netzfähigkeit von Merzerisierlaugen.
Die Netzfähigkeit von Merzerisationsflotten lässt sich bekanntlich dadurch erhöhen, dass man Mischungen von Phenolen und hydrierten Phenolen zusetzt. Es ist ferner bekannt, dass die Wirkungsweise dieser Produkte erhöht wird, wenn man zu den gleichen Mischungen noch weitere Zusätze, insbesondere auch von aliphatischen oder aromatischen Alkoholen macht. Durch diese weiteren Zusätze wird eine gleichmässigere und beim Aufbewahren der Flotten weniger rasch abnehmende Wirkung der Zusatzmittel erzielt.
Es wurde nun gefunden, dass es technisch vorteilhaft ist, die Mitverwendung von hydriertem Phenol beim Merzerisieren auszuschliessen, da dieses infolge seiner Flüchtigkeit sowohl die Beständigkeitseigenschaften der Flotten ungünstig beeinflusst, wie auch infolge des durchdringenden Geruchs seiner Dämpfe unangenehm empfunden wird. Allerdings sind hydrierte Phenole nicht enthaltende Kombinationen in ihrer Wirkungsweise völlig unbefriedigend, sofern nicht, wie gefunden wurde, aliphatische und aromatische Alkohole vom Typus des Benzylalkohols gleichzeitig mit Phenolkörpern kombiniert werden.
So besitzt beispielsweise die Ko mbination Benzylalkohol-Phenol nur geringe Netzkraft erhöhende Wirkung, während die Kombination Octylalkohol-oder Decylalkohol-Phenol sich in konzentrierten Laugen nur unvollkommen unter Bildung nicht stabiler Emulsionen löst. Dagegen ist die Kombination aus beispielsweise Benzylalkohol, Octylalkohol und Phenol von ausgezeichneter Wirkung, durchnetzt Baumwolle fast augenblicklich und löst sich in Laugen von 25-320 Be klar auf.
Beispiel :
Beispiel : Einer Merzerisierlauge von 320 Bé werden 1'5 Volumprozent einer Mischung zugesetzt, welche 93% Rohkresol, 4% Benzylalkohol und 3% normalen, primären Octylalkohol enthält. Auf diese Flotte aufgelegte Baumwollgewebestücke werden rasch durchnetzt und sinken unter, u. zw. rascher als in gleicher Flotte, der im gleichen Verhältnis eine Mischung von 93% Rohkresol und 7% Cyclohexanol zugefügt ist.
An Stelle von Octylalkohol sind auch andere aliphatische Alkohole, auch Mischungen, die sich aus den bei der Hochdruckhydrierung von Kokosfett anfallenden Fettalkoholen durch Destillation als Vorlauf abtrennen lassen, mit analogem Erfolg anwendbar. Statt Benzylalkohol ist beispielsweise auch auch Phenylätylalkohol brauchbar.

Process for increasing the wetting ability of mercerising liquors.
It is known that the wetting ability of mercerization liquors can be increased by adding mixtures of phenols and hydrogenated phenols. It is also known that the effectiveness of these products is increased if further additions are made to the same mixtures, in particular also of aliphatic or aromatic alcohols. These additional additives achieve a more even and less rapidly decreasing effect of the additives when the liquors are stored.
It has now been found that it is technically advantageous to exclude the use of hydrogenated phenol during mercerization, since this has an adverse effect on the stability properties of the liquors due to its volatility and is perceived as unpleasant due to the penetrating odor of its vapors. However, combinations which do not contain hydrogenated phenols are completely unsatisfactory in their mode of action, unless, as has been found, aliphatic and aromatic alcohols of the benzyl alcohol type are combined with phenolic compounds at the same time.
For example, the combination of benzyl alcohol-phenol has only a slight effect of increasing the wetting force, while the combination of octyl alcohol or decyl alcohol-phenol dissolves only incompletely in concentrated alkaline solutions with the formation of unstable emulsions. In contrast, the combination of benzyl alcohol, octyl alcohol and phenol, for example, has an excellent effect, wets cotton almost instantly and dissolves clearly in alkalis of 25-320 Be.
Example:
Example: A mercerizing liquor of 320 Bé is added with 1'5 percent by volume of a mixture which contains 93% raw cresol, 4% benzyl alcohol and 3% normal, primary octyl alcohol. Pieces of cotton fabric placed on this liquor are quickly wetted and sink below, u. between faster than in the same liquor to which a mixture of 93% raw cresol and 7% cyclohexanol is added in the same ratio.
Instead of octyl alcohol, other aliphatic alcohols, including mixtures which can be separated off from the fatty alcohols obtained in the high-pressure hydrogenation of coconut oil by distillation, can also be used with similar success. Instead of benzyl alcohol, for example, phenylethyl alcohol can also be used.
