Description

Verfahren zur Veredlung von Textilien In der Textilveredlungsindustrie spielen bekanntlich die Kondensationsprodukte aus Melamin (= Cyanursäure-triamVd) und Formaldehyd eine wichtige Rolle. Sie werden z. B. in großem Maßstab verwendet zur Knitterfestausrüstung von Kunstseide sowie zum Quellfestmachen von Zellwolle.Process for the finishing of textiles In the textile finishing industry is known to play the condensation products from melamine (= cyanuric acid triamVd) and formaldehyde play an important role. You will e.g. B. used on a large scale for the crease-proof finishing of rayon as well as for the swell-proofing of rayon.

Es wurde nun gefunden, .daß man für die Veredlung von Textilien vielfach an Stelle der Melamin-Formaldehyd-Kondensationsprodukte mit Vorteil solche aus Cyanursäure und Formaldehyd verwenden kann. Man erhält diese Kondensationsprodukte, wenn, man Cyanürsäure in bekannter Weise mit Formaldehyd, zweckmäßig in Form einer wäßrigen Lösung, erwärmt, bis Auflösung eingetreten ist, und dann gegebenenfalls noch einige Zeit offen weitererhitzt, so daß ein Teil des Wassers abdestillieren kann.It has now been found that one is often used for the finishing of textiles Instead of the melamine-formaldehyde condensation products, those made from cyanuric acid are advantageous and formaldehyde. These condensation products are obtained if, one Cyanuric acid in a known manner with formaldehyde, expediently in the form of an aqueous one Solution, heated until dissolution has occurred, and then some more if necessary Time to continue heating, so that some of the water can distill off.

Die erfindungsgemäß verwendeten Cyanursäure-Formaldehyd-Kondensationsprodukte eignen sich insbesondere hervorragend zum Naßknitterfestmachen von Baumwolle, wobei sich die so veredelte Ware gegenüber einer mit Melamnharz ausgerüsteten, durch wesentlich bessere Waschechtheiten auszeichnet. Ein weiterer Vorteil des Verfahrens der Erfindung besteht darin, daß die mit Cyanursäure-Formaldehyd-Kondensationsprodukten behandelten Textilien nur eine geringe Einbuße an Reißfestigkeit erleiden.The cyanuric acid-formaldehyde condensation products used according to the invention are particularly suitable for making cotton wet crease-proof, whereby The goods refined in this way are significantly different from those made with melamine resin characterized by better wash fastness. Another advantage of the method of the invention is that those treated with cyanuric acid-formaldehyde condensation products Textiles suffer only a slight loss of tear resistance.

Beispiel Ein mercerisiertes Baumwollgewebe wird mit 300 g/1 der 25%igen wäßrigen Lösung eines Cyanursäure-Formaldehyd-Kondensationspro.duktes, dessen Herstellung unten beschrieben ist, und 25 g/1 Magnesiumchlorid auf dem Foulard imprägniert, wobei die Flottenaufnahme des Gewebes, bezogen auf die lufttrockene Ware, 70 bis 80% beträgt. Nach der Imprägnierung wird das Gewebe bei 60 bis 80° C getrocknet und anschließend während 5 Minuten bei 150° C nacherhitzt.Example A mercerized cotton fabric is made with 300 g / 1 of the 25% aqueous solution of a cyanuric acid-formaldehyde condensation product, its production is described below, and 25 g / 1 magnesium chloride impregnated on the padder, the liquor pick-up of the fabric, based on the air-dry goods, 70 to 80%. After impregnation, the fabric is dried at 60 to 80 ° C and then post-heated at 150 ° C. for 5 minutes.

Die so behandelte Ware besitzt eine sehr gute Naßknitterfestigkeit und weist nur eine geringe Abnahme an Reißfestigkeit gegenüber dem unbehandelten Gewebe auf. Zur Herstellung des in obigem Beispiel verwendeten Kondensationsproduktes werden 390 g Cyanursäure mit 1180 g einer 36,51/oigen Formaldehydlösung unter Rühren im kochenden Wasserbad auf 95° C erhitzt, wobei nach kurzer Zeit eine klare Lösung entsteht. Diese wird sodann noch 3 Stunden im Wasserbad nachgerührt und hierauf im offenen Gefäß auf etwa 900 g eingedampft. Man erhält eine klare viskose Flüssigkeit, die sich in jedem Verhältnis mit Wasser verdünnen läßt; sie besitzt einen Feststoffgehalt von etwa 650g. Durch Zusatz der nötigen Menge Wasser kann sie z. B. auf einen Festgehalt von 25 % eingestellt werden.The goods treated in this way have very good wet crease resistance and shows only a small decrease in tear strength compared to the untreated Tissue on. For the preparation of the condensation product used in the above example 390 g of cyanuric acid are mixed with 1180 g of a 36.51% formaldehyde solution with stirring heated in a boiling water bath to 95 ° C, after a short time a clear solution arises. This is then stirred for a further 3 hours in the water bath and then evaporated to about 900 g in an open vessel. A clear viscous liquid is obtained, which can be diluted with water in any proportion; it has a solids content of about 650g. By adding the necessary amount of water, you can z. B. on a fixed salary of 25%.
