Description

Verfahren zur Veredlung von Textilien Die Verwendung der Kondensationsprodukte aus Aminotriazinen und Formaldehyd für die verschiedensten Z«-ecke der Textilveredlung ist bekannt. So werden im Schrifttum (vgl. beispielsweise die Patentschrift 702449 und die französischen Patentschriften 81 1 8o4, 823 25 0 , 82d.530 und- 826631) mannigfache Effekte, z. B. Knitterfestmachen, Steifappretur, Hydrophobierung, -Mattierung, Fixierung von löslichen oder unlöslichen Farbstoffen, Erhöhung der Schiebefestigkeit, Verhinderung des Schrumpfens, 1?rhöhung der Reißfestigkeit, ferner Erhöliuttg der Echtheitseigenschaften von Färbungen bei deti verschiedensten Textilfasern mit Hilfe von .lttiinotriazinformaldehydkondensationsprodukten beschrieben. Diese Verfahren haben unter Verwendung des Melamins eine große technische Bedeutung erlangt, obwohl ihnen noch mancherlei Mängel anhaften. So ist vielfach eine Beeinträchtigung der Lichtechtheit von Färbungen mit dieser Behandlungsweise verbunden.Process for the finishing of textiles The use of the condensation products of aminotriazines and formaldehyde for the most varied purposes of textile finishing is known. Thus, in the literature (see. For example, the patent specification 702449 and the French patents 81 1 8o4, 823 25 0 , 82d.530 and 82663 1 ) manifold effects, z. B. crease-proofing, stiff finishing, waterproofing, matting, fixing of soluble or insoluble dyes, increasing the slip resistance, preventing shrinkage, increasing the tear resistance, further increasing the fastness properties of dyeings in the most varied of textile fibers with the aid of .lttiinotriazinformaldehyde condensation products. These processes have achieved great technical importance using melamine, although they still have various shortcomings. This type of treatment is often associated with an impairment of the lightfastness of dyeings.

Es wurde nun gefunden, daß man mit besonderem Vorteil für die verschiedensten Zwecke der Textilveredlung Formaldehydkondensationsverbindungen von solchen 2, 6-Diaminotriazinen-r, 3, 5 verwendet, die in 4-Stellung eine durch eine Alkoxygruppe substituierte Alkylgruppe enthalten, wobei sich gegebenenfalls eine Überführung in den unlöslichen Zustand anschließt. Bei dieser Behandlungsweise wird insbesondere der obenerwähnte Nachteil der Beeinträchtigung der Lichtechtheit von Färbungen, die mit Hilfe von substantiven Farbstoffen auf celluloselialtigen Fasern hergestellt sind, in weitgehendem Maße vermieden. Das vorliegende Verfahren stellt daher eine wertvolle' Bereicherung der Technik dar. Beispiel Man verwendet eine 33o/oige wässerige Lösung der Tetramethylolverbindung des 2, 6-Diamino-4-(a-ät'hoxy)-äthyl-i, 3, 5-triazins.It has now been found that one with particular advantage for the most diverse Purposes of textile finishing formaldehyde condensation compounds of such 2,6-diaminotriazines-r, 3, 5 used, the alkyl group substituted by an alkoxy group in the 4-position contained, where appropriate a conversion in the insoluble state connects. With this mode of treatment, the above-mentioned disadvantage becomes particularly apparent the impairment of the light fastness of dyeings, which with the help of substantive Dyes on cellulosic fibers are produced to a large extent Dimensions avoided. The present procedure therefore represents a valuable enrichment of the Technique. Example A 330% aqueous solution of the tetramethylol compound is used des 2,6-diamino-4- (a-ethoxy) -ethyl-1,3,5-triazines.

Gut vorgereinigtes und entschlichtetes Zellwollegewebe wird auf einem geeigneten Apparat in einem Bad behandelt, das im Liter 5o bis 130 g der obigen Stammlösung und 2 bis 5,5 g einer 7o°/oigen Glykolsäure oder einen anderen geeigneten sauren Katalysator, wie Ameisensäure, Zinknitrat usw., enthält, und mit einem Abquetscheffekt von etwa iooo/o abgequetscht. Darauf wird zunächst bei Temperaturen zwischen 70 bis ioo° vorgetrocknet und anschließend einige Minuten auf etwa 13o bis i5o° erhitzt.Well pre-cleaned and desized staple viscose tissue is treated in a suitable apparatus in a bath containing 5o to 130 g of the above stock solution and 2 to 5.5 g of a 70% glycolic acid or another suitable acidic catalyst such as formic acid, zinc nitrate, etc. . Contains, and squeezed off with a squeeze effect of about iooo / o. This is followed by pre-drying at temperatures between 70 to 100 ° and then heated to around 130 to 150 ° for a few minutes.

Die Ware kann schließlich in üblicher Weise einer leichten Nachwäsche unterworfen werden. Man erhält auf diese Weise eine Ware von besonderer Trocken- und Naßreißfestigkeit und Quellwertsverminderung, die auch bei wiederholter Wäsche im wesentlichen erhalten bleiben.Finally, the goods can be lightly rewashed in the usual way be subjected. In this way, a product with a particularly dry and wet tensile strength and reduction in swelling value, even with repeated laundering are essentially preserved.

Verwendet man ein Zellwollgut, das vorher mit einem substantiven Farbstoff gefärbt wurde, so wird die Lichtechtheit der Färbung bemerkenswerterweise nicht herabgesetzt.One uses a Zellwollgut, which before with a substantive dye has been dyed, remarkably, the lightfastness of the dyeing does not become degraded.
