Description

In dem Patent 857 943 ist ein Verfahren zum Erhöhen der Knitterfestigkeit von Fasern und Geweben, insbesondere aus regenerierter Cellulose, beschrieben, bei welchem als Katalysator für die aus einer wäßrigen Lösung mehrwertiger, gegebenenfalls substituierter Aldehyde bestehenden Behandlungsflotte eine Säure verwendet wird, die mit der Fasersubstanz zu kondensieren vermag. Insbesondere kommen hierfür solche organischen Säuren in Betracht, die noch eine Carbonyl- oder Oxygruppe tragen.In patent 857,943 is a method of increasing the wrinkle resistance of fibers and Woven fabrics, in particular made of regenerated cellulose, described in which as a catalyst for the treatment liquor consisting of an aqueous solution of polyvalent, optionally substituted aldehydes an acid is used which is able to condense with the fiber substance. In particular, organic ones are used for this purpose Acids into consideration that still carry a carbonyl or oxy group.

Es wurde nun gefunden, daß unter den Oxysäuren diejenigen, die beim Erhitzen unter Wasserabspaltung ringförmige, esterartige Produkte zu bilden in der Lage sind, eine Sonderstellung einnehmen. Zu diesen Säuren zählen in erster Linie die aliphatischen α-Oxysäuren, wie Milchsäure oder Glycolsäure, welche beim Erhitzen in Lactid bzw. Glycolid übergehen. Infolge dieser Umwandlung sind bei Verwendung dieser Säuren als Katalysatoren für die Glyoxalierung oder anderweitige Knitterfreiausrüstung mittels mehrwertiger Aldehyde nach dem Trocknen des Textilgutes in diesem keine oder nur geringe Mengen freier Säuregruppen feststellbar. Diese Säuren werden also mit besonderem Vorteil dann benutzt, wenn die Fasern selbst säureempfindlich sind oder wenn die Stoffe mit einer säureempfindlichen Farbe gefärbt sind.It has now been found that, among the oxyacids, those which form with elimination of water on heating to form ring-shaped, ester-like products are able to occupy a special position. These acids include primarily the aliphatic α-oxyacids, such as lactic acid or Glycolic acid, which transforms into lactide or glycolide when heated. As a result of this transformation are when using these acids as catalysts for glyoxalation or otherwise Wrinkle-free treatment using polyvalent aldehydes after drying the textile in This no or only small amounts of free acid groups can be determined. These acids will so used with particular advantage when the fibers themselves are acid-sensitive or when the fabrics are dyed with an acid-sensitive color.

Beispielexample

Zu 95 1 Wasser gibt man 5 kg 300/oige Glyoxallösung, ι kg 35°/oige Glycolsäurelösung und 1 °/o eines handelsüblichen Weichmachers mit kation-To 95 1 of water, are 5 kg 30 0 / o glyoxal, ι kg 35 ° / o glycolic acid and 1 ° / o of a commercially available plasticizer with cationic

aktiver Wirkung, der vorher in H2O geschmolzen wurde. Die Temperatur dieser Flotte wird auf 350 gehalten, um ein Ausflocken des Weichmachers zu vermeiden. Durch die in das Chassis des Foulard gefüllte Flotte wird ein Zellwollmusseline von 180 g/m2 Gewicht so durchgezogen und abgequetscht, daß eine gleichmäßige Flüssigkeitsaufnahme von 100% entsteht. Die Ware wird dann langsam, etwa im Verlauf von 10 Minuten, bei 95° to getrocknet und in bekannter Weise fertiggestellt. Der behandelte Stoff zeigt einen Knitterwinkel von I2O°, während ein unbehandelter Stoff nur 6o° zeigt. Die Reaktion der Ware ist praktisch neutral oder liegt bei einem solchen pH-Wert, daß eine Schädigung der Cellulose bzw. der Färbung nicht mehr zu befürchten ist.active effect previously melted in H 2 O. The temperature of this liquor is kept at 35 0 in order to avoid flocculation of the plasticizer. A cellular wool muslin weighing 180 g / m 2 is pulled through the liquor filled into the chassis of the padder and squeezed off in such a way that 100% of the liquid is evenly absorbed. The goods are then slowly, in the course of 10 minutes, dried at 95 ° to and finished in a known manner. The treated fabric shows a crease angle of I20 °, while an untreated fabric shows only 60 °. The reaction of the product is practically neutral or is at such a pH value that damage of the cellulose or of the stain is no longer to be feared.
