Description

Das Patent 927871 betrifft ein Verfahren zur Hochveredlung, insbesondere zum Knitterfestmachen von vornehmlich Cellulosehydratfasern enthaltenden Textilien, wonach diese mit wäßrigen Lösungen von Vorkondensationsprodukten des Formaldehyde mit stickstoffhaltigen Verbindungen, wie Harnstoff oder seinen technischen Äquivalenten, in Anwesenheit von Gemischen aus Ammoniumsalzen starker. Mineralsäuren und solchen schwacher Säuren, insbesondere der Essigsäure, als Härtungskatalysatoren behandelt werden. Dadurch lassen sich einerseits hochwertige Effekte, insbesondere sehr gute Knitterfestigkeit, erzielen, andererseits wird die Absinkgeschwindigkeit des pH-Wertes der Flotte gegenüber der Verwendung von Ammoniumsalzen starker Mineralsäuren allein, die an sich sehr gute Effekte ergeben, bedeutend; vermindert. Infolgedessen bleiben die Flotten wesentlich länger gebrauchsfähig.Patent 927871 relates to a process for high-end finishing, in particular for making textiles primarily crease-resistant, containing cellulose hydrate fibers, according to which these are stronger with aqueous solutions of precondensation products of formaldehyde with nitrogen-containing compounds, such as urea or its technical equivalents, in the presence of mixtures of ammonium salts. Mineral acids and such weak acids, especially acetic acid, are treated as curing catalysts. Characterized on the one hand can be quality effects, especially very good crease resistance, achieve, on the other hand, the descending speed of the p H -value of the fleet over the use of ammonium salts of strong mineral acids alone, resulting in very good effects, meaning; reduced. As a result, the liquors can be used for much longer.

Es wurde nun gefunden, daß sich die gleichen Vorteile wie gemäß Hauptpatent auch erreichen lassen, wenn man an Stelle der Ammoniumsalze der schwachen Säuren die entsprechenden Natrium- und KaJiumsalze verwendet. Auch hier ist das Acetat besonders geeignet; aber auch die Salze anderer schwacher Säuren, wie z. B. die Carbonate oder Bicarbonate, sind gut anwendbar.It has now been found that the same advantages as in the main patent can also be achieved let, if instead of the ammonium salts of the weak acids, the corresponding sodium and KaJium salts used. Here, too, the acetate is particularly suitable; but also the salts of others weak acids such as B. the carbonates or bicarbonates are well applicable.

Die Mengen der Salze richten sich nach deren Art sowie nach der Menge und der Art des Vorkondensates, liegen aber in den gleichen Bereichen wie bei der Benutzung der Ammoniumsalze. Änderungen in der Menge wie auch im Mischungsver-The amounts of the salts depend on their type as well as on the amount and type of precondensate, but are in the same range as when using ammonium salts. Changes in the amount as well as in the mixing ratio

liältnis der Salze beeinflussen weiterhin die erzielbaren Effekte. So wird beispielsweise durch Anwendung einer kleineren Menge des Salzgemisdh.es eine geringere Knitter- und Quellfestigkeit bewirkt. Dies kann bei der Ausrüstung von pflanzlichen Fasern von Vorteil sein, welche einerseits eine stärkere Säureempfindliohkeit als Reyon und Zellwolle haben, deren geringeres Quellvermögen andererseits aber auc'h keine so starke Verminderung erfordert. Auch kann es bei der Behandlung von Textilien, welche mit säureempfindlichen Farbstoffen gefärbt sind, erwünscht sein, daß das pH besonders langsam absinkt bzw. bei. einem bestimmten Wert praktisch stehenbleibt. Dies kann durch die Verwendung von Natrium- und Kaliumsalzen schwacher Säuren gemeinsam mit Ammoniumsalzen der starken Säuren beispielsweise in einem Mengenverhältnis von ι: ι erreicht werden.The ratio of the salts continues to influence the achievable effects. For example, the use of a smaller amount of the salt mixture results in a lower crease and swell resistance. This can be of advantage when finishing vegetable fibers, which on the one hand have a stronger acid sensitivity than rayon and rayon, but on the other hand their lower swelling capacity does not require such a strong reduction. When treating textiles which have been dyed with acid-sensitive dyes, it may also be desirable for the pH to drop particularly slowly or at. practically stops at a certain value. This can be achieved by using sodium and potassium salts of weak acids together with ammonium salts of strong acids, for example in an amount ratio of ι: ι.

Es gelingt, durch Variation des- erfindungsgemäß beschriebenen Katalysatorengemisches optimale Ausrüstungseffekte je nach den Bedingungen der Praxis zu erzielen.It is possible to achieve optimal results by varying the catalyst mixture described according to the invention Achieve equipment effects depending on the conditions of the practice.
