Bevorzugt wird unter Zugabe eines Kältemittels gemahlen, beispielsweise Trockeneis oder flüssigem Stickstoff.
- 2. Die erfindungsgemäßen Präparationen können aber auch in besonderer Weise unter Verzicht auf ein Mahlaggregat so hergestellt werden, daß die erfindungsgemäßen Komponenten A, B und C in Form ihrer wäßrigen Lösungen, Suspensionen oder Anschlämmungen in einem Rührwerkskessel zusammengegeben werden und nach guter Durchmischung einem Trockenprozeß unterworfen werden, z.B. in einem Schaufeltrockner, Band- oder Siebtrockner, vorzugsweise aber einen Zerstäubertrockner, wenn die Präparationen nicht in flüssiger Form in den Handel gebracht werden sollen.

Mills suitable for dry grinding are, in addition to the ball mill or the disintegrator, but preferably those rotor-stator sieve mills which achieve a ⌀ grain size of less than 20 μm, preferably less than 5 μm, or so-called jet mills or impact chamber mills. It is preferred to add a refrigerant, for example dry ice or liquid nitrogen.
- 2. However, the preparations according to the invention can also be produced in a special way, without a grinding unit, in such a way that components A, B and C according to the invention are combined in the form of their aqueous solutions, suspensions or slurries in a stirred tank and, after thorough mixing, are subjected to a drying process are, for example in a paddle dryer, belt or screen dryer, but preferably an atomizer dryer, if the preparations are not to be marketed in liquid form.
Das Verhältnis von A:B in der Präparation beträgt 0,8 bis 2,4 Mol Komponente A zu 1 Mol Komponente B.The ratio of A: B in the preparation is 0.8 to 2.4 moles of component A to 1 mole of component B.

10 - 80 Gew.-% A + B,
78 - 18 Gew.-% C und gegebenenfalls
12 - 2 Gew.-% übrige Hilfsmittel,
wobei die Summe selbstverständlich 100 % ergeben muß.The finished preparations generally consist of
10 - 80% by weight A + B,
78-18% by weight of C and optionally
12-2% by weight of other auxiliaries,
the sum of course must be 100%.

Geeignete Fasermaterialien sind solche aus synthetischen Polymeren, wie Polyurethanen und synthetischen Polyamiden.Suitable fiber materials are those made of synthetic polymers, such as polyurethanes and synthetic polyamides.
Die Färbungen auf diesen Fasern können in herkömmlicher Weise sowohl mit Metallkomplexfarbstoffen als auch mit Säurefarbstoffen erzeugt werden. Bevorzugt sind die Metallkomplexfarbstoffe, insbesondere die 1:2 Chrom- oder 1:2 Kobalt-Komplexe von Mono- oder Diazoverbindungen, die in der Literatur in großer Zahl beschrieben und im Handel erhältlich sind. Diese Farbstoffe können auch 1 - 2 Sulfogruppen enthalten.The dyeings on these fibers can be produced in a conventional manner using both metal complex dyes and acid dyes. The metal complex dyes, in particular the 1: 2 chromium or 1: 2 cobalt complexes of mono- or diazo compounds, which are described in large numbers in the literature and are commercially available, are preferred. These dyes can also contain 1-2 sulfo groups.
Geeignete Säurefarbstoffe sind insbesondere solche Typen, die üblicherweise in Kombination mit den Metallkomplexfarbstoffen eingesetzt werden.Suitable acid dyes are, in particular, those types which are usually used in combination with the metal complex dyes.
Die Behandlung der Polyamidmaterialien mit den erfindungsgemäß zu verwendenden Kupferverbindungen kann vor, während oder nach, bevorzugt während der Färbung, erfolgen.The treatment of the polyamide materials with the copper compounds to be used according to the invention can take place before, during or after, preferably during the dyeing.
Die Färbungen werden nach üblichen Verfahren hergestellt, dh. im Ausziehverfahren auf dem Jet-Färbeapparat, dem Jigger, der Haspelkufe oder einem Spulfärbeapparat oder aufeiner Kontinue-Anlage nach den bekannten Klotz- oder Imprägierverfahren.The dyeings are produced by conventional methods, ie. in the pull-out process on the jet dyeing machine, the jigger, the reel runner or a reel dyeing machine or on a continuous machine according to the known block or impregnation processes.
Der wesentliche Vorteil der neuen Präparationen im Vergleich zu den vorgefertigten Kupfer-Komplexen (vergl. z.B. EP-A 51 188, 245 204, 252 386, 255 481 und DE-A 32 47 051) besteht darin, daß sie ohne großen mechanischen und verfahrenstechnischen Aufwand herstellbar sind.The main advantage of the new preparations compared to the prefabricated copper complexes (cf., for example, EP-A 51 188, 245 204, 252 386, 255 481 and DE-A 32 47 051) is that they have no great mechanical and procedural requirements Effort can be produced.
Dabei ist es als überraschend anzusehen, daß die neuen Präparationen praktisch die gleiche Wirksamkeit wie die separat hergestellten Kupfer-Komplexe aufweisen.It is surprising that the new preparations have practically the same effectiveness as the separately prepared copper complexes.
