Description
Verfahren zum Färben von Pelzen, Haaren, Federn u. dgl. Zusatz zum Patent 461752 Nach dem Verfahren des Hauptpatents 461 752 lassen sich Pelze. Haare. Federn und ähnliche Stoffe in einfacher und gefahrloser Weise färben, indem man sie bei gewöhnlicher Temperatur in einem Bade behandelt. das diazotierbare Aminoverbindungen, kupphmgsfähige Verbindungen und Nitrit, gegebenenfalls auch Seife, Türkischrotöl u. dgl. enthält, und dann das Bad durch Zusatz von Säuren oder sauren Verbindungen ansäuert oder die zweckmäßig abgequetschte oder abgeschleuderte Ware in eine saure Lösung bringt, der man vorteilhaft einen Zusatz von etwas Nitrit gibt. Hierbei war Voraussetzung, daß das Färbegut einer Vorbehandlung, z. R. mit: Alkalien, dem sogenannten Tötungsprnzeß, unterworfen wurde. um es zu entfetten, zu reinigen und auch für den Farbstoff aufnahmefähiger zu machen.Method for dyeing furs, hair, feathers and the like. Addendum to Patent 461 752 Furs can be prepared according to the method of main patent 461 752. Hair. To dye feathers and similar fabrics in a simple and safe manner by treating them in a bath at ordinary temperature. which contains diazotizable amino compounds, compounds capable of coupling and nitrite, possibly also soap, Turkish red oil and the like, and then acidifies the bath by adding acids or acidic compounds or brings the appropriately squeezed or spun off product into an acidic solution, which is advantageously an additive of some nitrite there. It was a prerequisite that the material to be dyed a pretreatment, e.g. Usually with: alkalis, the so-called killing process, was subjected. to degrease it, to clean it and also to make it more receptive to the dye.
Es wurde nun gefunden, daß sich diese Vorbehandlung des Tötens ohne Schwierigkeit mit dem obenerwähnten neuen Färbeerfahren zu einem einzigen Prozeß vereinigen läßt, wodurch eine weitere Vereinfachung dieses Zweiges der Färberei erzielt wird. Dem Bade können ferner auch Faserschutzmittel zugesetzt werden. Die erzielten Färbungen zeigen die gleichen Echtheitseigenschaften wie die nach dem Verfahren des Hauptpatents. Beispiel: In einem Bade, das im Liter 3,6 g 1-Aminonaphthalin, 50 ccm Monopolseifenlösung 1 ::20, 5,2 g 2-oxynaphthalin-3-carbonsaures Natrium und Zoo ccm Natriumnitritlösung 1 :'0, 5 ccm Ammoniak 25prozentig und 30 g Kochsalz enthält, wird das Fell etwa 2 Stunden bei gewöhnlicher Temperatux behandelt. Nach Zusatz von 1o ccm Ameisensäure 85prozentig wird etwa 3o Minuten weiterbehandelt. Nach dem Färben wird gut gespült. Man erhält eine schwarze Färbung.It has now been found that this pre-treatment of killing can be combined without difficulty with the above-mentioned new dyeing process into a single process, whereby a further simplification of this branch of dyeing is achieved. Fiber protection agents can also be added to the bath. The dyeings obtained show the same fastness properties as those according to the process of the main patent. Example: In a bath containing 3.6 g 1-aminonaphthalene, 50 cc monopole soap solution 1: 20, 5.2 g 2-oxynaphthalene-3-carboxylic acid sodium and zoo cc sodium nitrite solution 1: 0.5 cc ammonia 25 percent per liter and contains 30 g of table salt, the fur is treated for about 2 hours at normal temperature. After adding 10 cc of formic acid (85 percent), treatment is continued for about 30 minutes. Rinse well after dyeing. A black color is obtained.
