Abstract

The invention relates to a chloride-free catalyst for the finishing of textiles with formaldehyde-free crosslinking agents containing magnesium and fluoborate ions in the ratio 1:0.1 to 4. <??>The catalyst permits odour-free finishing.

Description

Wegen der anhaltenden Diskussion um den Einsatz von formaldehydhaltigen Hilfsmitteln in der Textilindustrie werden z.B. in der Hochveredlung von Textilien vermehrt formaldehydfreie Vernetzer verwendet, z.B. solche der Formel I

Figure imgb0001

in der
R¹, R²=H oder C₁- bis C₃-Alkyl mit der Maßgabe bedeuten, daß mindestens einer der Reste R¹ und R² eine C₁- bis C₃-Alkylgruppe ist, und R³, R⁴ für H oder C₁- bis C₄-Alkyl stehen.Because of the ongoing discussion about the use of formaldehyde-containing auxiliaries in the textile industry, formaldehyde-free crosslinking agents, for example those of the formula I, are increasingly used, for example, in the finishing of textiles
Figure imgb0001
in the
R¹, R² = H or C₁- to C₃-alkyl with the proviso that at least one of the radicals R¹ and R² is a C₁- to C₃-alkyl group, and R³, R⁴ are H or C₁- to C₄-alkyl.

Bei der Großproduktion in den Textilbetrieben wird jedoch gelegentlich eine äußerst unangenehme Geruchsbildung auf der ausgerüsteten Ware festgestellt, die in der Markteinführungsphase dieser Vernetzer nicht bemerkt wurde. Diese Geruchsbildung ist anscheinend die Folge einer katalytischen Zersetzung des Vernetzers bei höheren (Kondensations-)Temperaturen. Es entstehen leicht flüchtige Verbindungen, die zur Geruchsbelästigung bei der ausgerüsteten Ware führen - vor allem bei bereits konfektionierter und luftdicht verpackter Ware.In large-scale production in the textile factories, however, an extremely unpleasant odor is sometimes noticed on the finished goods, which was not noticed during the market launch phase of these crosslinkers. This odor formation is apparently the result of a catalytic decomposition of the crosslinker at higher (condensation) temperatures. Easily volatile compounds are formed, which lead to unpleasant smells in the finished goods - especially in the case of goods that have already been assembled and packed airtight.

Aufgabe der Erfindung war es, eine Möglichkeit zur Vermeidung dieser Geruchsbelästigung zu finden.The object of the invention was to find a way of avoiding this odor nuisance.

Die Erfindung betrifft nun einen chloridfreien Katalysator, bei dessen Verwendung keine Geruchsbelästigung mehr auftritt und der Magnesium- und Fluoborationen im molaren Gewichtsverhältnis Mg²⊕ : BF₄⊖ wie 1:0,1 bis 4, vorzugsweise 1:0,2 bis 2 enthält.The invention now relates to a chloride-free catalyst, in the use of which there is no more odor nuisance and which contains magnesium and fluoborate ions in a molar weight ratio of Mg² ⊕ : BF₄ ⊖ such as 1: 0.1 to 4, preferably 1: 0.2 to 2.

Vorzugsweise wird der Katalysator als wäßrige Lösung verwendet, die 15 bis 40 Gew.-%, vorzugsweise 20 bis 35 %, Salz enthält. Die Magnesium- und Fluoborationen können dabei in Salzform, z.B. als Magnesiumsulfat, -phosphat, -nitrat, -acetat, -glykolat, -citrat oder -adipat oder Natrium-, Lithium-, Kalium- oder Zinkfluoborat eingebracht werden. Besonders bevorzugt ist die Verwendung von Magnesiumsulfat, Magnesiumnitrat und Natriumfluoborat.The catalyst is preferably used as an aqueous solution which contains 15 to 40% by weight, preferably 20 to 35%, of salt. The magnesium and fluoborate ions can be in salt form, for example as magnesium sulfate, -phosphate, -nitrate, -acetate, -glycolate, -citrate or -adipate or sodium, lithium, potassium or zinc fluoroborate. The use of magnesium sulfate, magnesium nitrate and sodium fluoroborate is particularly preferred.

Die Anwendung des Katalysators bei der Hochveredlung erfolgt wie z.B. bei Magnesiumchlorid üblich, Anwendungsmengen liegen im Bereich von ungefähr 30 bis 50 Teilen einer beispielsweise 20 %igen Lösung, bezogen auf 100 Teile des Vernetzers (45 %ige Lösung). Gegenüber den bekannten Methoden ergeben sich bei dem neuen Katalysator keine Abweichungen.The catalyst is used in the finishing process, e.g. usual for magnesium chloride, application amounts are in the range of approximately 30 to 50 parts of a 20% solution, for example, based on 100 parts of the crosslinking agent (45% solution). There are no deviations from the known methods in the new catalyst.
