摘要： A dyeing process has been found which enables to dye uniformly polyacrylonitrile fiber materials, by using as dyestuffs basic azo dyestuffs being non-quarternized and containing neither cationic quaternary ammonium groups nor cationic N-substituted or N-unsubstituted iminium groups, said azo dyestuffs containing on the other hand at least one unsubstituted or substituted amino group, hydrazino group, amidino group or guanidino group capable of forming salts. The very dyeing process as such is carried out according to usual processing data for dyeing polyacrylonitriles in a slightly acid medium. Especially with the use of several of these dyestuffs for polychromic dyeing, such as trichromic dyeing, special advantages are obtained, insofar that even at cut-rate dyeing periods and for preparing light color shades, there are obtained even dyes with constant color shades, when using these dyestuffs having good migrating properties.

摘要： Fiber material composed of acid-modified homopolymers or copolymers of acrylonitrile (PAC fibers) which has been obtained by a wet spinning process, has not been dried and is still in a swollen condition (gel form), can be dyed advantageously and in fast colors by means of soluble dyes, the molecule of which contains several groups, namely more than one quaternary grouping and/or a strongly basic grouping carrying no charge, which exert a basic action towards the acid groups of the fiber substance. The chromophore of this colorant can belong to the category of monoazo or diazo dyes, methine, azamethine or diazamethine dyes or naphthalactam dyes.In accordance with the invention, after substantially removing the non-aqueous spinning solvent by washing, the spun material, as a moist gel, is dyed continuously or discontinuously from an aqueous dyebath; the fibers can be stretched before the dye is applied, during the dyeing process itself or immediately afterwards.By virtue of their special nature, the dyes of the type designated above, which have a strong fixing action, produce optimum fixing rates when dyeing PAC gels and, in the subsequent production stages, do not cause any noticeable soiling, as a result of dye which has bled out, on components of machines and operating baths, such as stretching or after-treatment baths. Investigations of penetration of the fiber by the dye, of the fixing rate and of the resulting fastness properties, such as fastness to wet processing, have shown no disadvantages compared with conventional dyes.

摘要： Improvement of a process for spin-dyeing acid-modified polymers or copolymers of acrylonitrile in which cationic quaternary dyestuffs are added to the spinning mass and spun according to the wet-spinning procedure. The improvement is characterized by using dyestuffs characterized by a migration factor M of 20 or less than 20, by a combination index K of less than 2.5 and a cation weight of more than 310. Migration factor M and combination index K are known values in the dyestuff field or can be determined. The dyestuff to be used according to the invention can belong to the most different classes of dyestuffs; they fix rapidly on the polymer, and thus they do not color, or color only to a minor extent, the coagulation, stretching and washing baths although they are soluble in water and aqueous solutions of these baths. The fibers and filaments obtained by the process of the invention have outstanding fastnesses to wet processing and, owing to the absence of dyestuff aggregates at the surface of the fiber such as occur when spin-dyeing with pigments, very good fastnesses to dry and wet rubbing. The fibers are intense, absolutely transparent and free from specks.

摘要： A process for the direct preparation of pure thiazolazo compounds had been found with the use of a 2-aminothiazole as diazo or azo component in a coupling process wherein the 2-aminothiazole used therein is subjected to the usual coupling reaction, if used as diazocomponent after diazotation, without intermediate isolation after its preparation in known manner. This process avoids the preparation of the 2-aminothiazoles as starting compounds in its solid form and the expensive purification of these instable compounds and yields now very pure azo products.

摘要： Chlorozincate salts of thiazolium azo compounds are prepared by reacting thiazolium azo compounds with an dialkylsulfate having from 1 to 4 carbon atoms in the alkyl radicals, which process comprises carrying out the reaction in an aqueous medium at a temperature of from about 10.degree. to 50.degree. C. in the presence of a zinc compound capable of binding acid, and with the use of from 1.8 to 2.5 mols of the dialkylsulfate, calculated on the starting azo dyestuff, at a pH not exceeding 8, preferably at 3-7. The prepared thiazolium azo compound is precipitated as chlorozincate salt, especially by means of an alkali metal chloride. According to this process, the chlorozincate salts are obtained in higher purity. A perceptible decomposition of the thiazolium azo compound does not occur. Chemicals, for example the alkylation agent and acid-binding agents need be used in a small quantity. In addition to this economy and to the less pollution of the waste water, the process has the advantage that it can be carried out with the use of a small reaction volume.
