Description
Verfahren zum Krumpffestmachen von Wolle Es wurde gefunden, daß man Wolle durch Behandlung mit Glyoxalsulfat in saurem wässerigem Medium, gegebenenfalls bei erhöhter Temperatur, und durch nachfolgende Trocknung krumpffestmachen kann.Method of shrink-proofing wool. It has been found that one can Wool by treatment with glyoxal sulfate in an acidic aqueous medium, optionally at elevated temperature, and by subsequent drying can make it shrink-proof.
Für das Verfahren kann auch gefärbte oder anderweitig veredelte Wolle verwendet Werden. Die erfindungsgemäß behandelte Wolle kann ferner danach den üblichen Faserveredelungsbehandlungen, wie Färben, Bleichen, Mottenfestmachen u. dgl., unterworfen werden. Diese Faserveredelungsverfahren lassen sich aber auch gleichzeitig mit dem Verfahren zum Krumpffestmachen gemäß vorliegender Erfindung ausüben.Dyed or otherwise refined wool can also be used for the process be used. The wool treated according to the invention can then also use the usual Subjected to fiber finishing treatments such as dyeing, bleaching, moth-proofing and the like will. These fiber refinement processes can also be carried out simultaneously with the Practice shrink-proofing methods of the present invention.
Gegenüber der bekannten krumpffestmachenden Behandlung mit Chlor bietet das vorliegende Verfahren den Vorteil, daß es keinen Gewichtsverlust an Wolle verursacht, keine Vergilbung, sondern eine Aufhellung der Wolle bewirkt, die Farbstoffaufnahmefähigkeit der Wolle nicht und die Filzfähigkeit der Wolle nur wenig verändert. Gegenüber der bekannten krumpffestmachenden Behandlung mit Harzen zeichnet sich das vorliegende Verfahren dadurch aus, daß es die Lichtechtheit nicht verschlechtert, die Aufnahmefähigkeit der Wolle für Farbstoffe nicht verändert und keiner hohen Reifetemperatur bedarf.Compared to the well-known anti-shrink treatment with chlorine the present process has the advantage that it does not cause any weight loss in wool, no yellowing, but a lightening of the wool causes the dye absorption capacity of the wool and the felting ability of the wool only slightly changed. Compared to the Known anti-wrinkle treatment with resins, the present one stands out Process in that it does not impair the light fastness, the absorption capacity the wool for dyes does not change and does not require a high ripening temperature.
Beispiel 2,5 g Glyoxalsulfat und 2,5 g Glaubersalz werden in 5 1 Wasser gelöst; die Lösung wird mittels Schwefelsäure auf einen pH-Wert von 1,9 eingestellt. In diesem Bad werden ioo g Wolle etwa 2o Minuten bei ungefähr 40° behandelt. Dann wird die Wolle, ohne zu spülen, geschleudert und bei etwa 5o° getrocknet. Das durch die beim Schleudern ablaufende Flüssigkeit ergänzte und mit Schwefelsäure wieder auf einen pH-Wert-i,9 eingestellte Bad kann für mehrere Partien verwendet werden.Example 2.5 g of glyoxal sulfate and 2.5 g of Glauber's salt are dissolved in 5 l of water; the solution is adjusted to a pH of 1.9 using sulfuric acid. In this bath 100 g of wool are treated for about 20 minutes at about 40 °. Then the wool is spun without rinsing and dried at about 50 °. The bath, which is supplemented by the liquid that runs off during the spinning and adjusted to a pH value of 1.9 with sulfuric acid, can be used for several batches.
Die so erhaltene Wolle ist krumpffest und zeigt außerdem eine 'um etwa 15% erhöhte Reißfestigkeit.The wool obtained in this way is resistant to shrinkage and also shows a 'um about 15% increased tear strength.
