Definitions

  • the object of the invention was to find a way to avoid this nuisance.
  • 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 Mg 2 ⁇ : BF4 ⁇ of 1: 0.2 to 1: 2.
  • 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.
  • the catalyst is used in high finishing, 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.
  • a BW fabric (100 g / m2) is impregnated with the following solutions using a padder.
  • Catalyst solution 1 8.7 parts MgSO4 calz. 2.0 parts NaBF4 29.3 H2O
  • Catalyst solution 2 8.7 parts MgSO4 calz. 2.5 parts of Zn (BF4) 2 29.5 H2O
  • Catalyst solution 3 4.0 parts MgSO4 calz. 5.0 parts of Mg (NO3) 2 ⁇ 6 H2O 0.5 parts NaBF4 20.5 H2O
  • the finished goods were packed airtight in a polyethylene film, stored for 24 hours and then subjected to an odor test.

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, vgl. EP-A-0359039.
  • 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.
  • Aufgabe der Erfindung war es, eine Möglichkeit zur Vermeidung dieser Geruchsbelästigung zu finden.
  • Die Erfindung betrifft nun einen chloridfreien Katalysator, bei dessen Verwendung keine Geruchsbelästigung mehr auftritt und der Magnesium- und Fluoborationen im molaren Gewichtsverhältnis Mg2⊕ : BF₄⊖ von 1:0,2 bis 1:2 enthält.
  • 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.
  • 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.
    • Experimentelles:
  • Ein BW-gewebe (100 g/m²) wird mit folgenden Lösungen mittels eines Foulards imprägniert. Flottenaufnahme ca. 80 %.
    Katalysator-Lösung 1: 8,7 Teile MgSO₄ calz.
    2,0 Teile NaBF₄
    29,3 H₂O
    Katalysator-Lösung 2: 8,7 Teile MgSO₄ calz.
    2,5 Teile Zn(BF₄)₂
    29,5 H₂O
    Katalysator-Lösung 3: 4,0 Teile MgSO₄ calz.
    5,0 Teile Mg(NO₃)₂ · 6 H₂O
    0,5 Teile NaBF₄
    20,5 H₂O
    Figure imgb0002
  • Die ausgerüstete Ware wurde luftdicht in einer Polyethylenfolie verpackt, 24 Stunden gelagert und danach einer Geruchsprüfung unterworfen.
  • Die gemäß den Beispielen 1 bis 3 behandelten Muster waren geruchlos, die gemäß den Beispielen 6 und 7 wiesen einen leichten Geruch auf und die gemäß den Beispielen 4 und 5 rochen äußerst unangenehm.
