Definitions

• the present invention relates to a process oiimproving dyeings on textile fibers and similar material.
• dyeings' of organic dyestuffs can be improved by causing the said dyestuffs to interact on the dyed material with organic bases like amines, quaternary ammonium compounds or 10 soluble salts thereof.
• organic bases like amines, quaternary ammonium compounds or 10 soluble salts thereof.
• the metal complex compounds to be used according to our invention are derived from or- 40 ganic bases which may belong to the aliphatic or cyclic series.
• the metal complex compounds of guanidino guanidine, oi thiourea, of c-phenanthroline, of phenylene diamines, or -2.2'-dipyridyl, of 8- amino-quinoline, oi 8-amino-quinaldine and the like.
• the metals suitable for preparing the compounds to be used according to our invention are of the type which easily forms complex compounds with organic bases, for instance, chromium, iron and especially copper.
• the process oi our invention may be carried out by ai'tertreating the dyed fibers withan aqueous solution oi one of the said complex metal compounds; if desired, the solution may '55 be weakly acid or alkaline.
• the dyeing is per- The aqueous solution 01 the copper vcomplex oi the compound of the following constitution:
• the above mentioned compound is obtainable by reacting upon 1 mol of cyanuric chloride with 1 mol of m-amino-phenyl-trimethyl am- 'moniumchloride and 1 mol of 5-amino-8-hydroxy-quinoline.
• Example 2 A 2% dyeing on cotton with the dyestufi which is obtained by coupling in an alkaline medium diazobenzene and diazotized 2-naphthylamine-6- sulionic acid with the urea of I-acid, is treated, after washing, for half an hour at 30 C. with an aqueous solution of the complex compound pre.. pared from cupric sulfate and. B-amino-quinaldine (obtainable by stirring an alcoholic solution or B-amino-quinaldine into an aqueous cupric sulfate solution). By this treatment the scarlet red dyeing becomes dark brown and acquires a good fastness to washing.
• Example 3 A 2% dyeing oi Diamine Pure Blue FF is dull and faster to washing.
• Example 4 Cotton which has been dyed with 7% of Sirius Black L (comp. Schultz, Farbstofltabellen, Erganzungsband, 1934, page 132) is treated in an aqueous. solution at 30 C.- prepared from o-phenanthroline-cupric-chloride (obtainable from ophenanthroline and cupric chloride). The dyeing becomes more greenish and is improved as regards its iastness to washing.
• Example 5 The fastness to water and washing of cotton dyeings prepared with Diamine Green B are improved on aftertreating the same with solutions of the complex salts prepared from cupric chloride with 1 or 2 mols of a.u-dipyridyl.
• the fastness to washing of the dyeings is also improved by using the corresponding complex iron salts.
• Example 6 Cotton dyed with Direct Deep Black EW extra is aftertreated with the solution of the cupric complex salt of NN-tetramethyl-o-phenylene-diamine.
• Such solutions may, for instance, be obtained by adding'l mol of base and 1 mol of copper acetate in alcohol and dilution with water of this alcoholic solution which, if desired, may have been filtered.
• the Iastness to water of the aftertreated dyeings is improved.
• the modification which comprises causing the dyed fibers to interact with a complex metal compoundof a cyclic base containingv at least two basic nitrogen atoms which metal compound is capable 01' forming salts with acids.
• the modification which comprises treating the dyed fibers with an aqueous solution of a complex copper compound of a N-heterocyclic base containing at least two basic nitrogen atoms which'copper compound is capable of forming salts with acids.
• the modification which comprises treating the dyed fibers with an aqueous solution of a complex-copper compound of 8-amino-quinoline which copper compound is capable of forming salts with acids.
