Description
aus Gerbsäure und Formaldehyd.from tannic acid and formaldehyde.
Die nachfolgende Erfindung richtet sich auf ein Verfahren zur Herstellung von Stoffen und Geweben, die sich zu Bekleidungszwecken besonders eignen, weil sie mit Kondensationsprodukten aus Gerbsäure und Formaldehyd imprägniert sind. Derartige Stoffe und Gewebe wirken desinfizierend und adstringierend auf die Epidermis; denn durch die Schweißentwicklung werden dieThe following invention is directed to a method for producing Fabrics and fabrics that are particularly suitable for clothing purposes because they contain Condensation products of tannic acid and formaldehyde are impregnated. Such Fabrics and tissues have a disinfecting and astringent effect on the epidermis; because through the development of sweat, the
ίο Kondensationsprodukte allmählich wieder in Gerbsäure und Formaldehyd zersetzt. Dagegen können die Stoffe mit Seife und Wasser ohne Bedenken gereinigt werden; denn die Kondensationsprodukte werden dadurch weder abgelöst noch gespalten.ίο Condensation products gradually back in Decomposes tannic acid and formaldehyde. On the other hand, the fabrics can be cleaned with soap and water without hesitation; because the condensation products are neither detached nor split.
Das neue Verfahren besteht darin, daß die Kondensationsprodukte auf der Faser, und zwar ohne Hilfe eines Kondensationsmittels, lediglich durch Erhitzen erzeugt werden.The new process is that the condensation products on the fiber, and can be generated without the aid of a condensing agent, merely by heating.
Die Ausführung erfolgt beispielsweise wie folgt:The execution takes place as follows, for example:
i. Imprägnierung von Halbwollstoffen. i. Impregnation of semi-wool fabrics.
Die Stoffe werden als Garn oder als Rohstoffe mit einer starken Lösung von Gerbsäure (Tannin, Sumach, Dividivi usw.) kochend behandelt und dann kalt ausgewaschen. Darauf bringt man die Ware in ein Bad aus 16 Teilen Formaldehydlösung von 40 Prozent und 120 Teilen Wasser und erhitzt ι bis 2 Stunden im Dampfbade. Man wäscht nun aus Und trocknet.The fabrics are made as yarn or as raw materials with a strong solution of tannic acid (Tannin, sumac, dividivi, etc.) treated at the boil and then washed out with cold water. The goods are then brought into a bath 16 parts of formaldehyde solution of 40 percent and 120 parts of water and heated ι up to 2 hours in the steam bath. You wash out and dry.
2. Imprägnierung von Baumwollstoffen. 2. Impregnation of cotton fabrics.

Bei vorstehender Arbeitsweise wird nur die Wolle imprägniert; soll die Baumwolle mit dem Kondensationsprodukt imprägniert werden, so arbeitet man wie folgt:In the above procedure, only the wool is impregnated; should the cotton are impregnated with the condensation product, work as follows:
Die Baumwollstoffe werden, wie bei 1., mit Tannin oder dergl. behandelt, aber nicht ausgewaschen, sondern getrocknet. Hierauf bringt man sie in eine wässerige Lösung von Brechweinstein und sodann in ein Bad aus 12 Teilen Formaldehyd von 40 Prozent und 120 Teilen Wasser, in dem man sie ι bis 2 Stunden mit Dampf kocht. Hierauf wird ausgespült und getrocknet.As in 1., the cotton fabrics are treated with tannin or the like, but not washed out but dried. They are then brought into an aqueous solution vomiting tartar and then in a bath of 12 parts formaldehyde of 40 percent and 120 parts of water, in which they are boiled for up to 2 hours with steam. On that is rinsed and dried.
Statt des Brechweinsteins kann man andere analog wirkende Beizen, z. B. basische Farbstoffe verwenden.Instead of the tartar you can use other similar pickling, z. B. basic dyes use.
3. Imprägnierung von Wollstoffen. Hierbei arbeitet man genau wie bei 1.3. Impregnation of woolen fabrics. Here you work exactly as with 1.
