Description

Appreturmittel Die Erfindung betrifft die Herstellung von Appreturen mittels Superpolyamiden, d. h. linearen hochpolymeren Kondensationsprodukten, die durch die im Molekül befindlichen NHCO-Gruppen charakterisiert sind und z. B. aus ww'-Diaminen und ww'-Dicarbonsäuren oder aus Aminocarbonsäuren bzw. deren Lactamen entstehen.Finishing Agents The invention relates to the manufacture of finishes by means of super polyamides, d. H. linear high polymer condensation products that are characterized by the NHCO groups in the molecule and z. B. off ww'-diamines and ww'-dicarboxylic acids or from aminocarboxylic acids or their lactams develop.

Die Verarbeitung von Superpolyamiden auf Appreturen stößt im allgemeinen auf Schwierigkeiten, weil sich die Superpolyamide in der Regel in den praktisch in Frage kommenden Lösungsmitteln nicht lösen. Eine Ausnahme in dieser Hinsicht bilden aber diejenigen Superpolyamide, welche aus zwei Ausgangsstoffen, die je für sich zur Superpolyamidbildung befähigt sind und von denen min-Bestens einer eine Aminocarbonsäure oder ein funktionelles Derivat einer solchen ist, hergestellt sind. Derartige Superpolyamide erhält man beispielsweise, indem man einerseits Gemische von Hexamethylendiamin und Adipinsäure oder Salzen aus diesen Verbindungen, andererseits e-Aminocarbonsäure oder deren Lactam zusammenkondensiert. An Stelle der Adipinsäure kann beispielsweise auch ein funktionelles Derivat dieser Säure; z. B. ein Ester, Amid oder das Anhydrid, Verwendung gefunden haben. Auch kann statt der Adipinsäure eine andere Dicarbonsäure sowie statt des Hexamethylendiamins ein anderes Diamin verwendet worden sein. Derartige Mischsuperpolyamide lassen sich auch durch Erhitzen mit gegebenenfalls wasserhaltigen aliphatischen Alkoholen in Lösung bringen, wodurch eine wichtige Vorbedingung für ihre Verwendung als Appreturmittel erfüllt ist.The processing of super polyamides on finishes is generally encountered on difficulties because the super polyamides are usually in the practical Do not dissolve the solvents in question. An exception in this regard but form those superpolyamides, which are made from two starting materials, each for are capable of superpolyamide formation and of which min-best one is one Aminocarboxylic acid or a functional derivative thereof. Superpolyamides of this type are obtained, for example, by using mixtures on the one hand of hexamethylenediamine and adipic acid or salts from these compounds, on the other hand e-aminocarboxylic acid or its lactam condensed together. Instead of adipic acid can, for example, also be a functional derivative of this acid; z. B. an ester, Amide or the anhydride, have found use. Also can instead of adipic acid another dicarboxylic acid and another diamine instead of hexamethylene diamine have been used. Such mixed superpolyamides can also be obtained by heating with possibly water-containing aliphatic alcohols in solution bring about an important prerequisite for their use as a finishing agent is satisfied.

Die vorstehend erwähnten Mischsuperpolyamide sind nun aber nicht sämtlich in gleicher Weise für die Herstellung von Appreturmitteln geeignet. Es ist gefunden worden, daß man Appreturen von besonders guten Eigenschaften erhält, wenn man von der in Rede stehenden Gruppe von Mischsuperpolyamiden solche verwendet, die nur in Gemischen von Alkoholen mit Wasser gut löslich, in reinen alphatischen Alkoholen dagegen nicht oder nur wenig löslich sind. Unter wenig löslichen Produkten sind dabei solche zu verstehen, die sich zu weniger als I5% lösen. Unter einer guten Löslichkeit ist eine solche von mehr als 15 0/o, beispielsweise 2o bis 25 0/o, zu verstehen.The above-mentioned mixed superpolyamides are not all equally suitable for the production of finishing agents. It is found that one obtains finishes with particularly good properties if one of of the group in question of mixed superpolyamides used only Easily soluble in mixtures of alcohols with water, in pure alphatic alcohols however, are not or only slightly soluble. Among the poorly soluble products are to understand those that resolve less than 15%. Under a good one Solubility is more than 15%, for example 20 to 25% to understand.

Mischsuperpolyamide von dem angegebenen speziellen Löslichkeitsverhalten führen zu Appreturen, welche heißwasserbeständig sind. Die aus Mischsuperpolyamiden von anderem Löslichkeitsverhalten hergestellten Appreturen sind gegenüber der Einwirkung von heißem Wasser nicht beständig. Daß gerade die Mischsuperpolyamide, die sich überhaupt erst unter Mitverwendung von Wasser in größerer Menge in Lösung bringen lassen, heißwasserbeständige Appreturen ergeben, war naturgemäß sehr überraschend: Solche Mischsuperpolyamide, die in reinen alphatischen Alkoholen nicht oder nur in geringem Maße, dagegen in Gemischen dieser Alkohole mit Wasser gut löslich sind, erhält man beispielsweise bei Verwendung- von adipinsaurem Hexamethylendiamin und Caprolactam als Ausgangsstoffe dann, wenn eine der beiden Komponenten in merklich höherer Menge als die andere angewendet wird, z. B. bei Verwendung von mindestens etwa 6o Teilen von adipinsaurem Hexamethylendiamin auf 4o Teile Caprolactam. Die Appreturmittel gemäß der Erfindung zeichnen sich dadurch aus, daß die mit ihnen hergestellten Appreturen eine hohe Abrieb- bzw. Kratzfestigkeit aufweisen. Neben der guten Wasserbeständigkeit der Appreturen ist im übrigen noch ihre Anfärbbarkeit mit den verschiedensten Farbstoffen hervorzuheben.Mixed superpolyamides with the specified special solubility behavior lead to finishes that are resistant to hot water. The ones made from mixed super polyamides Finishes produced with different solubility behavior are opposed to the action not resistant to hot water. That just the mixed super polyamides that only bring it into solution using larger quantities of water leave, result in hot water-resistant finishes, was naturally very surprising: Such mixed superpolyamides, which are not or only in pure alpha alcohols to a small extent, but are readily soluble in mixtures of these alcohols with water, is obtained, for example, when using adipic acid and hexamethylenediamine Caprolactam as starting materials when one of the two components is noticeable higher amount than the other is applied, e.g. B. when using at least about 60 parts of hexamethylenediamine adipate to 40 parts of caprolactam. the Finishing agents according to the invention are characterized in that with them The finishes produced have a high abrasion and scratch resistance. Next to The good water resistance of the finishes is also their ability to be dyed to be highlighted with a wide variety of dyes.

Die Herstellung von Lösungen von Mischsuperpolyamiden durch Erhitzen derselben mit Gemischen aus aliphatischen Alkoholen und Wasser ist bereits Gegenstand des Patents 718 33o. Die dort aufgeführten Mischsuperpolyamide lassen sich aber auch durch Erhitzen mit reinem Alkohol in Lösung bringen: Beispiel Zum Appretieren eines Gewebes aus Zellwolle oder Baumwolle wird eine Lösung von Io Teilen eines Mischsuperpolyamids, das durch Kondensation von 6o Teilen adipinsaurem Hexamethylendiamin und 4o Teilen Caprolactam erhalten worden ist, in 9o Teilen eines 7o%igen wasserhaltigen Methylalkohols benutzt. Das Gewebe wird in die etwa 6o° warme Lösung eingetaucht, anschließend zwischen Gummiquetschwalzen abgepreßt und danach getrocknet und gebügelt. Die erzielte Appretur bleibt in kochendem Wasser erhalten.The preparation of solutions of mixed superpolyamides by heating them with mixtures of aliphatic alcohols and water is already the subject of patent 718 33o. The mixed superpolyamides listed there can also be brought into solution by heating with pure alcohol: For example, a solution of 10 parts of a mixed superpolyamide obtained by condensation of 60 parts of adipic acid hexamethylenediamine and 40 parts of caprolactam is used to finish a fabric made of rayon or cotton , used in 90 parts of a 7o% aqueous methyl alcohol. The fabric is dipped into the approximately 60 ° warm solution, then pressed between rubber squeeze rollers and then dried and ironed. The finish obtained is preserved in boiling water.
