Dr.W.ZERWICK Frankfurt a/M Fechenheim, den 10.Februar 1949Dr W. ZERWICK Frankfurt a / M Fechenheim, February 10, 1949
Es wurde gefunden, dass man Wolle durch Behandlung mit Glyoxalsulfat in saurem wässerigem Medium, gegebenenfalls bei erhöhe ter Temperatur, und durch nachfolgende Trocknung krumpffest machen kann.It has been found that wool can be increased by treatment with glyoxal sulfate in an acidic aqueous medium, if necessary with ter temperature, and can make it shrink-proof by subsequent drying.
Für das Verfahren kann auch gefärbte oder anderweitig veredelte Wolle verwendet werden. Die erfindungsgemäss behandelt© Wolle kann ferner danach den üblichen Faserveredelungsbehandlungen, wie Färben, Bleichen, Mottenfestmachen usw., unterworfen werden.©ie*« se Faserveredelungsverfahren lassen sieh aber auch gleichzeitig mit den Verfahren zum Krumpffestmachen gesiäss vorliegender Erfindung aus®Dyed or otherwise refined wool can also be used for the process. The treated according to the invention © Wool can then be subjected to the usual fiber finishing treatments, such as dyeing, bleaching, moth-proofing, etc. © ie * « However, these fiber refinement processes also omit the process for shrink-proofing according to the present invention
üben. Gegenüber der bekannten krumpfffestmachenden Behandlung mit Chlor bietet das vorliegende Verfahren den Vorteil, dass ©s keinen Gewichtsverlust an Wolle verursacht, keine Vergilbung sondern ei«» η© Aufhellung der Wolle bewirkt, die FarbstoffaufnahmefEiligkeit der Wolle nicht und die Filzfähigkeit der Wolle nur wenig verändert. Ge« gesüber der bekannten krumpffestmachenden Behandlung mit Harzen zeiel·.^ net sich das vorliegende Verfahren 'dadurch aus, dass es die Lieht* eehtheit nieht verschlechtert, die Aufnahmefähigkeit der Wolle für Farbstoffe nicht verändert und keiner hohen Reifetemperatur bedarf. Beispiel sto practice. Compared to the known anti-shrink treatment with chlorine, the present process offers the advantage that there is no Loss of weight in wool causes, no yellowing but rather a lightening of the wool, which causes the dye to take up Not wool and only slightly changes the wool's ability to felt. Compared to the well-known anti-shrinkage treatment with resins, see The present method is characterized by the fact that it does not worsen the looseness, the absorption capacity of the wool for Dyes not changed and does not require a high ripening temperature. Example s
2,5 gi» Glyoxalsulfat und 2,5 gr Glaubersalz werden in 5 44T. Wasser gelöst] die Lösung wird mittels Schwefelsäure auf einen pH-Wert von 1,9 eingestellt. In diesem Bad werden 100 gr Wolle etwa 20 Minuten bei ungefähr 40°-G behandelt. Dann wird die Wolle ohne zu spülen geschleudert und bei etwa 50° getrocknet. Das durch die beim Schleudern ablaufende Flüssigkeit ergänzte und mit Schwefelsäure wieder auf einen pH Wert 1,9 eingestellte Bad kann für mehrere Par» tien verwendet werden.2.5 g of glyoxal sulfate and 2.5 g of Glauber's salt are in 5 44T. Dissolved water] the solution is adjusted to a pH of 1.9 using sulfuric acid. In this bath 100 grams of wool are treated for about 20 minutes at about 40 ° -G. Then, the wool is thrown without rinsing and dried at about 50 °. The bath, which is supplemented by the liquid running off during the spinning and adjusted to a pH value of 1.9 with sulfuric acid, can be used for several parties.
Die so erhaltene Wolle ist krumpffest und zeigt ausserdem eiae um etwa 15% erhöhte Reissfestigkeit.The wool obtained in this way is resistant to shrinkage and also shows an approximately 15% increase in tensile strength.
