Description

Verfahren zum Schützen von Wolle, Pelzwerk u. dgl. gegen Mottenfraß. Durch das Patent 346598 ist ein Verfahren geschützt, Wolle, Pelzwerk u, dgl. vor Mottenfraß zu schützen. Es ist durch die Verwendung der. Kieselfluorwasserstoffsäure gekennzeichnet. Die Wolle wird zu diesem Zweck nach Art des Färbeprozesses mit der Säure behandelt oder damit besprengt..Method for protecting wool, fur and the like against moth damage. Patent 346598 protects a method for protecting wool, fur and the like from being eaten by moths. It is through the use of the. Hydrofluoric acid labeled. For this purpose, the wool is treated with the acid or sprinkled with it according to the type of dyeing process.

Es wurde nun die bemerkenswerte Beobachtung gemacht, daß man an Stelle der Kieselfluorwasserstoffsäure auch andere komplexe Säuren, wie Phosphorwolframsäure, Phosphormolybdänsäure, Antimonwolframsäure, benutzen kann. Die Behandlung der Wolle usw. mit diesen Säuren kann in der Weise geschehen, daß -die Wolle z. B. mit den wässerigen Lösungen der Säuren oder mit ihren wasserlöslichen oder kolloidlöslichen Verbindungen behandelt bzvV. daß unlösliche Verbindungen dieser Säuren auf der Wolle erzeugt werden, z. B. durch aufeinanderfolgende Behandlung in verschiedenen Bädern. Beispiel r.The remarkable observation has now been made that one in place hydrofluoric acid also contains other complex acids, such as phosphotungstic acid, Phosphomolybdic Acid, Antimony Tungstic Acid. Treatment of wool etc. with these acids can be done in such a way that -the wool z. B. with the aqueous solutions of the acids or with their water-soluble or colloid-soluble Connections dealt with bzvV. that insoluble compounds of these acids on wool generated, e.g. B. by successive treatment in different baths. Example r.

ioo Gewichtsteile Wolle werden eine Stunde lang mit 3 Gewichtsteilen phosphorwolframsaurem Natron, io Gewichtsteilen Glaubersalz und 3 Gewichtsteilen Schwefelsäure unter Anwendung des üblichen Flottenverhältnisses erwärmt, gespült und getrocknet.100 parts by weight of wool are mixed with 3 parts by weight for one hour Phosphorus tungstate of soda, 10 parts by weight of Glauber's salt and 3 parts by weight Sulfuric acid heated using the usual liquor ratio, rinsed and dried.

Beispiele. ioo Gewichtsteile Wolle werden mit 5 Gewichtsteilen Natriumphosphat, io Gewichtsteilen Glaubersalz, 3 Gewichtsteilen Schwefelsäure eine Stunde lang gekocht; nach dem Erkalten imBade ausgepreßt und; ohne zu spülen, in ein kaltes oder warmes salpetersaures Bad von io Gewichtsteilen molybdänsaurem Ammoniak gebracht, wodurch sich auf der Faser die Molybdänphosphorsäure bildet. Nach einer Stunde wird gespült und getrocknet.Examples. 100 parts by weight of wool are mixed with 5 parts by weight of sodium phosphate, 10 parts by weight of Glauber's salt and 3 parts by weight of sulfuric acid boiled for one hour; squeezed out in the bath after cooling down and; without rinsing, in a cold or warm brought a nitric acid bath of 10 parts by weight of ammonia molybdenum, whereby The molybdenum phosphoric acid forms on the fiber. After an hour, it is rinsed and dried.
