Description

Verfahren zum Krumpffestmachen von wollehaltigem Material Es wurde gefunden, daß man wollehaltiges Material durch Behandlung mit Kondensationsprodukten aus Dicyandiamid oder Dicyandiamidin und Formaldehyd in saurem wäßrigem Medium, gegebenenfalls bei erhöhter Temperatur, krumpffest machen kann.Method of making woolen-containing material shrink-proof found that wool-containing material can be obtained by treatment with condensation products from dicyandiamide or dicyandiamidine and formaldehyde in an acidic aqueous medium, if necessary, at elevated temperature, can make it resistant to shrinkage.

Für das Verfahren kann insbesondere gefärbte oder anderweitig veredelte Wolle verwendet werden. Die erfindungsgemäß behandelte Wolle kann ferner danach bei Anwendung geeigneter Mittel den üblichen Faserveredelungsbehandlungen, wie Bleichen, Mottenfestmachen usw., unterworfen werden. Diese F aserveredelungsverfahren lassen sich aber auch gleichzeitig mit dem Verfahren zum Krumpffestmachen gemäß vorliegender Erfindung ausüben. Gegenüber der bekannten krumpffestmachenden Behandlung mit Chlor bietet das Verfahren den Vorteil, da:ß es keinen Gewichtsverlust an Wolle verursacht, keine Vergilbung noch Faserschädigung der Wolle bewirkt und die Färbung der Wolle kaum verändert. Gegenüber der bekannten krumpffestmachenden Behandlung mit Harzen zeichnet sich das vorliegende Verfahren dadurch aus, daß es keiner hohen Reifetemperatur bedarf.For the process, in particular, colored or otherwise refined Wool can be used. The wool treated according to the invention can also thereafter if suitable agents are used, the usual fiber finishing treatments, such as bleaching, Moth mooring, etc., are subjected. Let this fiber finishing process but also at the same time with the method of shrinking according to the present Practice invention. Compared to the well-known anti-shrink treatment with chlorine the process has the advantage that: it does not cause any weight loss in wool, No yellowing or fiber damage to the wool and the coloring of the wool barely changed. Compared to the well-known anti-shrink treatment with resins The present process is characterized by the fact that it does not require a high ripening temperature requirement.

Das Verfahren vorliegender Erfindung zeigt bei seiner Anwendung auf Halbwolle noch den besonderen Vorteil, daß gleichzeitig mit dem Krumpffesteffekt auch die für die erwähnten Kondensationsprodukte bekannte Verbesserung der Naßechtheit des gefärbten Baumwollanteils der Halbwolle erzielt wird. Beispiel io g eines Kondensationsproduktes, hergestellt durch mehrstündiges Erwärmen von 84 Teilen Dicyandiamid in Zoo Teilen 3oo/oigem Formaldehyd und 3ö Teilen 85°/äiger Ameisensäure auf 95 bis 98° und nachfolgendes Eindampfen im Vakuum, werden in 25oo bis 5000 ccm Wasser gelöst; die Lösung wird mit Essigsäure auf einen pH-Wert von 3 bis q. eingestellt. In dieser Lösung werden ioo g Wolle etwa 1/2 Stunde bei etwa 5o° behandelt. Dann wird die Wolle geschleudert und getrocknet. Die so erhaltene Wolle ist krumpffest.The method of the present invention, when applied to half-wool, also has the particular advantage that, at the same time as the anti-shrink effect, the improvement in the wet fastness of the dyed cotton portion of the half-wool, known for the condensation products mentioned, is achieved. Example 10 g of a condensation product, prepared by heating 84 parts of dicyandiamide in zoo parts of 300% formaldehyde and 30 parts of 85% formic acid to 95 to 98 ° and subsequent evaporation in vacuo, are dissolved in 250 to 5000 cc of water for several hours; the solution is brought to a pH of 3 to q with acetic acid. set. 100 g of wool are treated in this solution for about 1/2 hour at about 50 °. Then the wool is spun and dried. The wool obtained in this way is resistant to shrinkage.

Ersetzt man das obengenännte Kondensationsprodukt durch Kondensationsprodukte, die nach Patentschrift 671 log. aus Dicyandiamid, Formaldehyd und Ammoniumsalzen hergestellt werden, so erhält man ähnliche Effekte. Das gleiche ist der Fall, wenn man statt D@icyandiami@d #Dicyandiamidin verwendet.If the above-mentioned condensation product is replaced by condensation products, the log according to patent specification 671. from dicyandiamide, formaldehyde and ammonium salts produced, similar effects are obtained. The same is the case though instead of D @ icyandiami @ d #Dicyandiamidine is used.
