Description

Verfahren zum Walken von Wolle und Haaren In der Patentschrift 676 637 ist ein Walkverfahren beschrieben, das darin besteht, daß man Walkflüssigkeiten verwendet, die wasserlösliche Salze der Meta-, Pyro- oder Polyphosphorsäuren oder Gemische aus diesen Salzen enthalten.Method of fulling wool and hair In patent 676 637 a fulling process is described which consists in the fact that one fulling liquids used the water-soluble salts of meta-, pyro- or polyphosphoric acids or Contain mixtures of these salts.

In weiterer Ausbildung dieses Verfahrens wurde gefunden, daß man an Stelle der wasserlöslichen Alkalisalze der wasserarmen Phosphorsäuren die in der Patentschrift 715 5q.o beschriebenen Einwirkungsprodukte von Phosphorsäuren auf Säureamide oder deren Derivate, wie Harnstoffe, Urethane, Carbaminsäurederivate oder solche Stickstoffverbindungen, wie Nitrile, welche sich durch Wasseranlagerung in Säureamide umlagern können, zum Walken verwendet. Gleichartige Verbindungen entstehen auch durch Einwirkung von gasförmigem Ammoniak und Phosphorpentoxyd. Man erzielt mit diesen Produkten nicht nur einen gesteigerten Walkeffekt, sondern auch eine Abkürzung der Walkzeit sowie eine um etwa 2o% stärkere Schrumpfung als mit den entsprechenden phosphorsauren Salzen. Ein weiterer Vorteil der verbesserten Ausführungsform gegenüber dem Verfahren gemäß Patent 676 637 besteht noch darin, daß diese Produkte sich besonders zur Durchführung der Walke beim isoelektrischen Punkt der Wolle, also bei einem PH-Wert von etwa 5 eignen und daß sie ferner infolge ihrer Pufferungseigenschaften ein starkes Anwachsen der Alkalinität der Flotte verhindern, und zwar auch dann, wenn durch vorhergehende Waschvorgänge oder sonstige Zusätze sowie durch Umsetzung mit Calcium- und Magnesiumverbindungen ein höherer pH-Wert zwangläufig eintreten würde.In a further development of this process it was found that one can Place the water-soluble alkali salts of the phosphoric acids low in water in the Patent 715 5q.o described action products of phosphoric acids Acid amides or their derivatives, such as ureas, urethanes, carbamic acid derivatives or nitrogen compounds such as nitriles, which are formed by water attachment can rearrange in acid amides, used for fulling. Similar connections arise also through the action of gaseous ammonia and phosphorus pentoxide. One achieves with these products not only an increased flexing effect, but also a Shortening of the flexing time and about 20% more shrinkage than with the corresponding ones phosphoric acid salts. Another advantage over the improved embodiment the method according to patent 676 637 is that these products are particularly for performing the fulling at the isoelectric point of the wool, i.e. at one PH values of about 5 are suitable and that they are also due to their buffering properties prevent a strong increase in the alkalinity of the fleet, even if if through previous washing processes or other additives as well as a higher pH value inevitably due to the reaction with calcium and magnesium compounds would occur.

Beispiel i Wollstückware im Gewicht von 5o kg wird auf dem Walkzylinder behandelt mit einer Walkfiüssigkeit, die 0,4 kg einer gemäß Beispiel i des Patents 715 54o erhaltenen Stickstoff-Phosphorsäure-Verbindung und 0,4 kg getrocknete Sulfitablauge enthält.Example i Piece goods weighing 50 kg are treated on the fulling cylinder with a fulling liquid which contains 0.4 kg of a nitrogen-phosphoric acid compound obtained according to example i of patent 715 54o and 0.4 kg of dried sulphite waste liquor.

Beispiel a In einer ioo-l-Flotte werden 5 kg der gleichen Stickstoff-Phosphorsäure-Verbindung wie im Beispiel i, 500 g Calciumoxyd und ioog eines Natrönsalzes eines oleinsauren Schwefelsäureesters gelöst und in der etwa 5o° warmen Lösung 15 kg angebeizte Haare 5 Stunden lang behandelt. Nach dem Abschleudern werden die Haare in ein 2o° warmes Bad gegeben, das auf iao 1 Flotte 2,41 konzentrierte Salpetersäure enthält, 25 Minuten behandelt, geschleudert und getrocknet. EXAMPLE a 5 kg of the same nitrogen-phosphoric acid compound as in Example 1, 500 g of calcium oxide and a sodium salt of an oleic acid sulfuric acid ester are dissolved in a 100 l liquor and 15 kg of stained hair are dissolved in the approximately 50 ° warm solution for 5 hours treated. After spinning, the hair is placed in a 20 ° warm bath which contains nitric acid concentrated to 1 liquor 2.41, treated for 25 minutes, spun and dried.
