Description

Verfahren züm SchÜtzen von Wolle, Pelzwerk, Haaren u. dgl. gegen Nottenfraß. Durch das Patent 347721 ist die gegen Mottenfraß sichernde Wirkung von anorga-,nischen fixen Säuren, wie Wolframsäure usw., geschützt.Process for protecting wool, fur, hair and the like against emergency damage. Through the patent 347721 the anti-moth-preventive effect is inorganic, organic fixed acids such as tungstic acid, etc., protected.

Es wurde nun #die bemerkenswerte Beobachtung gemacht, daß auch Flußsäure, eine flüchtige anorganische Säure, und ihre Salze, wie Zinkfluorid, Alum-iniumfluorid, Titanfluorid usw., eine in hohem Grade mottensichernde Wirkung besitzen. Die Salze wer-,den zweckmäßig in Form ihrer wasserlösliehen Hydrate bzw. iin kollodiallöslicher Form verwendet.The remarkable observation has now been made that hydrofluoric acid, a volatile inorganic acid, and its salts, such as zinc fluoride, aluminum fluoride, Titanium fluoride, etc., have a highly mothproof effect. The salts are expediently in the form of their water-soluble hydrates or colloidal acids Shape used.

Be i s p i e 1.For example 1.

ioo Gewichtsieile Wolle werden mit einer Lösung von 3 Gewichts-teilen Aluminiumfluorid. etwa i Stunde unter den in der Färberei üblichen Flottenverhältnissen mit Glaubersalz und Schwefelsäure oder Ameisensäure erhitzt, gut gespült und getrocknet.100 parts by weight of wool are mixed with a solution of 3 parts by weight of aluminum fluoride.
