Description

Abänderung des Verfahrens zum Schutze der tierischen Faser bei der Behandlung mit alkalischen Flüssigkeiten.Modification of the procedure for the protection of animal fibers in the Treatment with alkaline liquids.

Zusatz zum Patent 373929. In dem Hauptpatent wurde ein Zerfahren zum Schutze der tierischen Faser bei der Behandlung mit alkalischen Flüssigkeiten beschrieben, welches darin besteht, daß man diesen alkalischen Flüssigkeiten Aldehyd- oder Ketonbisulfitverbindungen zusetzt.Addition to patent 373929. In the main patent, a disintegration was made to Protection of animal fibers when treated with alkaline liquids is described, which consists in adding aldehyde or ketone bisulfite compounds to these alkaline liquids clogs.

Es wurde nun gefunden, daß so wie Formaldehydbisulfit sich auch: die Bisulfitverbindung des Hexamethylentetramins, des Kondensationsproduktes von Formaldehyd und Ammoniak (vgl. H a r t u n g , Journ. f. prakt. Chemie, N. F. Bd.46, S. io) verhält.It has now been found that, like formaldehyde bisulfite, also: the Bisulfite compound of hexamethylenetetramine, the condensation product of formaldehyde and ammonia (cf. H a r t u n g, Journ. f. Practical Chemistry, N. F. Vol. 46, p. io) behaves.

Beispiel i.Example i.

Man wäscht unentschweißte Wolle eine halbe Stunde lang bei 5o° mit einer Lösung von 2o g wasserfreiem Natriumkarbonat und das Wasser klar abläuft. Die gereinigte Wolle besitzt ihren natürlichen, Glanz und Elastizität. Beispiele.The unwelded wool is washed for half an hour at 5o ° with a solution of 2o g of anhydrous sodium carbonate and the water runs off clear. The cleaned wool has its natural shine and elasticity. Examples.

Rohseide wird eine Stunde lang bei 5o° mit einer Lösung- von 6 bis c) - Natriumh vdroxyd und i bis 2 g Hexatnethylentetraminbisulfit im Liter behandelt. Die Seide wird dann gespült, leicht ab gesäuert und nochmals gespült. Die so entbastete Seide hat von ihrem Glanz und ihrer Festigkeit nichts eingebüßt.Raw silk is for one hour at 5o ° with a solution from 6 to c) - treated sodium hydroxide and 1 to 2 g Hexatnethylenentetraminbisulfit per liter. The silk is then rinsed, slightly acidified and rinsed again. The so deboned Silk has lost none of its shine and strength.

Beispiel 3. Example 3.

Man beschickt das Färbebad mit i Teil Schwefelfarbstoff, 1,5 bis 2 Teilen Schwefelnatrium, o,5 bis i Teil Hexamethylentetraminbisulfit und der üblichen Menge Natriumsulfat und behandelt damit halbwollenes Gewebe eine Stunde lang bei 30 bis 35°. Die Baumwolle wird gedeckt, die Wolle bleibt fast ungefärbt und behält ihre Festigkeit, Elastizität und ihren weichen Griff.The dyebath is charged with 1 part of sulfur dye, 1.5 to 2 parts of sodium sulfur, 0.5 to 1 part of hexamethylenetetramine bisulfite and the usual amount of sodium sulfate, and half-woolen fabric is treated with it for one hour at 30 to 35 °. The cotton is covered, the wool remains almost undyed and retains its strength, elasticity and its soft feel.
