Description
Verfahren zur Herstellung von in Dispersionen überführbaren Präparaten au$ wasserunlöslichen oder schwerlöslichenFarbstoffen oder Farbstoffzwischenprodukten Um wasserunlösliche oder schwerlösliche Stoffe in wäßrige Dispersionen überzuführen, hat man sie bisher in gelöstem, geschmolzenem oder fein suspendiertem Zustand - mit wäßrigen Lösungen geeigneter Dispergierungsmittel behandelt. Dadurch erzielte man fertige Dispersionen, welche in dieser Form in den Handel kamen. Die vollkommenste Handelsform im Gegensatz zur Paste ist jedoch das Pulver. Solche trockenen, pulverförmigen Präparate aus organischen Farbstoffen und deren Zwischenprodukten waren bisher auf einfache Weise nicht herzustellen.Process for the production of preparations which can be converted into dispersions from water-insoluble or sparingly soluble dyes or dye intermediates To convert water-insoluble or sparingly soluble substances into aqueous dispersions, if you have so far in a dissolved, molten or finely suspended state - treated with aqueous solutions of suitable dispersants. This scored one finished dispersions, which came in this form on the market. The most perfect In contrast to paste, however, the commercial form is powder. Such dry, powdery Preparations made from organic dyes and their intermediates were previously available easy way not to manufacture.
Nach Veröffentlichungen von P 1 a u s o n und von v. W e i m a r n ist es bekannt, durch mechanische Zerkleinerung unlöslicher fester Stoffe bis zu kolloiden Dimensionen zu gelangen.According to publications by P 1 a u s o n and by v. W e i m a r n it is known by mechanical comminution of insoluble solids up to to reach colloidal dimensions.
Die Anwendung dieses Prinzips zur Herstellung von dispersen Präparaten für die Acetatseidenfärberei hat gezeigt, daß mit der in der Farbentechnik üblichen gewöhnlichen Mahlapparatur durch Trockenmahlung geeignete Färbepräparate erhalten werden können, die zwar an sich noch- nicht kolloid zerteilt sind, beim Auflösen in Wasser jedoch durch die Wirkung des mifvermählenen Dispergierungsmittels ohne weiteres hochdisperse Lösungen von kolloiden Dimensionen :ergeben. Gegenstand vorliegender Erfindung sind nun Präparate für die Verwendung in, der Acetatseidenfärberei in trockener Pulverform, die wasserunlösliche oder schwerlösliche organische Farbstoffe oder Zwischenprodukte, Dispergierungsmittel und gegebenenfalls Schutzkolloide enthalten und die befähigt sind, beim übergießen mit heißem Wasser eine Dispersion zu liefern. Diese Präparate sind an sich nicht von kolloidaler Feinheit. Sie stellen eine innige Mischung dar von zu dispergierendem Stoff mit Dispergierungsmittel und haben die Eigenschaft, beim Auflösen in heißem Wasser unter der chemisch-physikalischen Wirkung des Dispergierungsmittels Dispersionen zu bilden. Außer ihrer ausgezeichneten gewerblichen Verwertbarkeit weisen die mit Seifenpulver durch gewöhnliches Vermahlen direkt hergestellten Farbstoffpräparate vor allen anderen die fortschrittliche Wirkung auf, daß sie ohne weiteren sonst gebräuchlichen Seifenzusatz zum Färben verwendet werden können und daß reibechte Färbungen auf Acetatseide damit erzielt werden, bei denen -ein nachträgliches Abseifen des Färbegutes, das die anderen Verfahren erfordern, hier unnötig wird.The application of this principle for the production of disperse preparations for acetate silk dyeing has shown that with the usual in dye technology ordinary grinding apparatus obtained by dry grinding suitable dyeing preparations which in themselves are not yet colloidly divided when dissolving in water, however, due to the action of the mifahlenen dispersant without further highly dispersed solutions of colloidal dimensions: result. Subject of the present Invention are now preparations for use in, acetate silk dyeing in dry powder form, the water-insoluble or sparingly soluble organic dyes or contain intermediates, dispersants and optionally protective colloids and which are capable of providing a dispersion when poured over with hot water. These preparations are not in themselves of colloidal delicacy. You represent an intimate Mixture of the substance to be dispersed with dispersant and have the Property, when dissolved in hot water, under the chemical-physical effect of the dispersing agent to form dispersions. Except for their excellent commercial ones Those produced directly with soap powder by ordinary grinding show usability Dye preparations above all others have the advanced effect that they are without other otherwise common soap additives can be used for dyeing and that rubbing-fast dyeings on acetate silk can thus be achieved, in which -a subsequent Soap off the dyed material, which the other processes require, is unnecessary here.
Zur praktischen Ausführung des neuen Verfahrens werden entweder die vorgemischten pulverförmigen Stoffe durch eine wirksame Schlagmühle zerkleinert und zur Erzielung einer guten Durchmischung nochmals in einer 1Vlischmaschine behandelt, oder die-trockenen Stoffe werden auf einem Kollergang gemahlen, nochmals zerkleinert und gemischt.For the practical implementation of the new method, either the premixed powdery substances are crushed by an effective hammer mill and treated again in a blender to achieve good mixing, or the-dry Substances are ground on a pan mill, crushed and mixed again.
Auf diese Weise werden homogen aussehende Präparate erzielt, die sich in Wasser unter dem Einfluß der zugesetzten Dispergierungsmittel leicht zu Dispersionen (Suspensionen, Emulsionen bis Lösungen) verteilen und in dieser Form den verschiedensten Verwendungszwecken, beispielsweise der Herstellung von Farblösungen in der Färberei und Druckerei, ganz besonders auf dem Gebiete der Acetatseidenfärberei; zugeführt werden können.In this way, homogeneous looking preparations are achieved that are easy to form dispersions in water under the influence of the added dispersing agent (Suspensions, emulsions to solutions) and in this form the most varied Uses, for example the production of dye solutions in dyeing and printing, especially in the field of acetate silk dyeing; fed can be.
Als Dispergierungsmittel lassen sich bei dem beschriebenen Verfahren die in der Praxis bekannten verwenden, sofern sie trocken, fest und mahlbar sind. Ambesten hat sich jedoch trockenes Seifenpulver bewährt. Als Schutzkolloide können dienen: Stärke, Dextrin, British Gum oder andere Abbauprodukte der Stärke; Leim, arabischer Gummi und andere Gummiarten. Beispiel i q.o Teile Arninoazobenzöl werden mit 6o Teilen Seife auf einem Kollergang so lange gemahlen, bis eine Probe des Pulvers durch Lösen in heißem Wasser m eine Dispersion über-g eht. Beispiel z 18 Teile I # q.-Diaminoanthrachinon, 45 Teile Seifenpulver und 37 Teile British Gum, zu inniger Mischung in einer Perplexmühle vermahlen, ergeben ein dunkles Pulver, das von heißem Wasser leicht aufgenommen wird.The dispersants which can be used in the process described are those known in practice, provided they are dry, solid and grindable. However, dry soap powder has proven itself best. The following can serve as protective colloids: starch, dextrin, British gum or other starch breakdown products; Glue, arabic gum and other types of gum. Example i qo Arninoazobenzöl parts are ground with 6o parts soap on a pan mill until a sample of the powder by dissolution in hot water m a dispersion exceeded g eht. Example z 1 8 parts of I # q.-diaminoanthraquinone, 45 parts of soap powder and 37 parts of British gum, ground to an intimate mixture in a perplex mill, give a dark powder which is easily absorbed by hot water.
Beispiel 3 i a Teile Dianisidin mit 6o Teilen Seife und 28 Teilen Stärke werden in einem Kollergang und nachher in einer Perplexmühle gut gemahlen. Sie liefern beim Übergießen mit heißem Wasser eine Dispersion.Example 3 ia parts of dianisidine with 60 parts of soap and 28 parts of starch are ground well in a pan mill and then in a perplex mill. When hot water is poured over them, they produce a dispersion.
