Description

Verfahren zur Gerbung, Imprägnierung usw. von Stoffen. Die Erfindung betrifft eine weitere Ausbildung ides Verfahrens nachdem Patent 3.52671. Nach dem Hauptpatent wird zur Gerbung, Imprägnierung usw. von Stoffen so vorgegangen, daß die zu -behandelnden Stoffe mit Hilfe der Elektroosmose vorgegerbt und hierauf im Gerbbottich oder Walkfaß in üblicher Weise ohne Anwendung von Strom fertig gegerbt wenden.Process for tanning, impregnating, etc. fabrics. The invention relates to a further development of the method according to patent 3,52671. According to the main patent, the tanning, impregnation, etc. of materials is such that the materials to be treated are pretanned with the aid of electroosmosis and then finished-tanned in the usual way in the tanning vat or fulling barrel without the use of electricity.

Nachdem vorliegenden Verfahren wird nun in der Weise gearbeitet, daß die elektroosmotisehe Einwirkung mit einer sehr dünnen Gerblösung von etwa o,1 bis o,5° B6 vorgenommen wird. Es hat sich nämlich gezeigt, daß die elektroosmotische Behandlung mit nur eine Spur von Gerbstoff enthaltenden Lösungen genügt, um die Blößen so zu beeinflussen, daß sie im Walkfaß oder Gerbbottich in kurzer Zeit mechanisch fertig gegerbt werden können. Es wird so für die mechanische Gerbung eine, Ersparnis an Gerbstoff erzielt, und auch für die elektrische Vorbehandlung ergibt sich eine Verminderung der erforderlichen Leistung und Einwirkungsdauer. Auch beim Imprägnieren läßt sich die Erfindung in vorteilhafter Weise verwenden. Ausführungsbeispiel. In einem :dreiteiligen Gerbapparat wird die Blöße in einer dünnen Gerbstofflösung von o,i bis o,5° B6 der Wirkung eines Gleichstromes von 3o- Volt 2.4 Stunden unterworfen. Die so vorbehandelte Blöße wird im Walkfaß mit etwa 6° Be starker Gerblösung während 2.4 Stunden gegerbt.After the present method is now worked in such a way that the electroosmotic action with a very thin tanning solution of about 0.1 to o.5 ° B6 is made. It has been shown that the electroosmotic Treatment with solutions containing just a trace of tannin is sufficient to remove the To influence pelts so that they mechanically in a short time in the fulling barrel or tanning vat ready to be tanned. It becomes a saving for mechanical tanning achieved in tanning agent, and also for the electrical pretreatment there is one Reduction of the required performance and duration of exposure. Even when impregnating the invention can be used in an advantageous manner. Embodiment. In a: three-part tanning apparatus is the pelt in a thin tanning solution of 0.1 to 0.5 ° B6 subjected to the action of a direct current of 30 volts for 2.4 hours. The pelt that has been pretreated in this way becomes tanning solution in the fulling barrel with about 6 ° Be Tanned for 2.4 hours.

,Als Gerbstoffe können bei der elktroosmotisahen Behandlung z. B. Fichten- und Kastanienholzextrakt,ebenso Quebracho-, Sumachurvd Gallenextrakte benutzt werden. Als Brühen für die Gerbun.g im Faß dienen zweckmäßig größtenteils Gemenge aus Brühen dieser Gerbstoffe. Das Leder wird nach der Behandlung im Walkfaß in üblicher Weise gefettet und geglättet., As tannins can be used in the elktroosmotisahen treatment z. B. Spruce and chestnut extracts, as well as quebracho and sumac bile extracts are used will. The broths for tanning in the barrel are mostly mixed from broths of these tannins. The leather becomes more usual after treatment in the fulling barrel Way greased and smoothed.
