- United States Patent U.S. Cl. 8-46 2 Claims ABSTRACT OF THE DISCLOSURE Process for the production of water-insoluble azo dye stuffs on textile material comprising treating the textile material in an alkaline bath containing a coupling component and a compound of the formula wherein R is a radical of an aromatic or heterocyclic amine, Me is an alkali metal or alkaline earth metal and n is 1 or 2, a Wetting or dispersing agent and, optionally, an inorganic salt, and producing the dyestuff by treatment with acid agents below 40 C.
- water-insoluble azo dyestuffs can be produced on textile material comprising cellulose or protein fibers by treating the textile material in an alkaline bath containing a coupling component and a diazoamino or tetrazoamino compound of the formula in which R represents the radical of an aromatic or heterocyclic amine, Me represents an alkali metal or alkaline earth metal and It stands for one of the integers 1 and 2, a wetting or dispersing agent and, if desired, an inorganic salt, and producing the dyestuff by treatment with acid agents below 40 C.
- the process of the invention is carried out by treating the textile material in the form of yarn in hanks, wound bodies, combed or loose material in an alkaline bath which contains a coupling component having a high substantivity and a diazoamino or tetrazoamino compound of the above formula, a wetting or dispersing agent and, if desired, an inorganic salt, for example sodium chloride, sodium phosphate or sodium sulfate.
- the treatment is carried out for at least minutes so that the coupling component can be sufiiciently and uniformly fixed on the textile material. In general. the treatment is carried out at room temperature or at moderately elevated temperature, preferably below 35 C.
- an organic acid is added to the bath, for example formic acid, acetic acid, tartaric acid, citric acid, lactic acid or glycolic acid or a mixture of said acids or a mixture of an inorganic acid, for example hydrochloric acid or sulfuric acid, with an organic acid, in an amount such that the total quantity of alkali in the bath and on the textile material is neutralized and a pH value beween about 4 and 7 is attained, the temperature being below 40 C.
- the dyestuff is produced on 3,441,364 Patented Apr. 29, 1969 the textile material.
- the treated material is then Washed in a neutral or acid bath, if desired in the presence of dispersing agents and the dyeing is finished in the usual manner. Dyeings which possess an excellent fastness to rubbing are obtained.
- Piece goods can be dyed by impregnating the goods on :1 padding machine having two or more rollers with a mixture of the coupling component and an excess of diazoamino or tetrazoamino compound, rolling them together, and after 30 minutes for example, coupling is effected by passing the treated goods through an organic acid, a mixture of organic acids or a mixture of organic and inorganic acids at a temperature below 40 C.
- This process can also be performed by passing the material through a compartment of a roller vat or by several passages on a jig or on a Winch vat, in which process additions of inorganic salts and dispersing agents sometimes show an excellent effect in the impregnating and developing stage.
- compounds can be used which are distinguished by a high substantivity for the textile material, i.e. coupling components which at a goods-to-liquor ratio of 1:20, a dyeing period of 30 minutes at 30 C., a concentration of 1 gram per liter of water without the addition of salts and an excess of 4.5 grams of sodium hydroxide per liter of bath, possess such a high substantivity that at least 9 grams are absorbed by 1 kilogram of cotton.
- a high substantivity for the textile material i.e. coupling components which at a goods-to-liquor ratio of 1:20, a dyeing period of 30 minutes at 30 C., a concentration of 1 gram per liter of water without the addition of salts and an excess of 4.5 grams of sodium hydroxide per liter of bath, possess such a high substantivity that at least 9 grams are absorbed by 1 kilogram of cotton.
- Suitable compounds are, for example: 2,3-hydroxynaphthoylamino-benzenes such as 1-(2',3-hydroxynaphthoylamino)-2,5-dimethoxy-4-chlorobenzene or 1-(2',3-hydroxynaphthoylamino) 2 methoxy-4-chloro-5-methylbenzene; 6-bromoor 6-methoxy-2,3-hydroxynaphthoic acid aryl amides such as l-(6'-bromo-2',3-hydroxynaphthoylamino)-2-methoxybenzene; condensation products of 2,3-hydroxynaphthoic acid and polynuclear isocyclic or heterocyclic amines such as 2-(Z',3-hydroxynaphthoylamino)-naphthalene, 2-(2,3'-hydroxynaphthoylarnino) -carbazole, 2-(2'
- the compounds commonly used in the ice-colour technique enter into consideration, for example condensation products of high molecular weight fatty acids and protein degradation products, condensation products of high molecular weight fatty acids and aminoalkyl-sulfonic acids, condensation products of formaldehyde with naphthalene-sulfonic acids or purified sulfite cellulose waste liquor.
- the process of the present invention can be carried out on textile material of natural or regenerated cellulose, cyano-ethylated cellulose, wool, natural silk, regenerated protein fibers or on mixtures of natural or regenerated cellulose with copolymers of acrylonitrile, vinylidene chloride and N-vinylpyrrolidone.
- the process of the present invention provides an essential simplification.
- the dyebath is discharged after impregnation with the coupling component, the fabric is centrifuged, filtered with suction or subjected to an intermediate rinsing, and the dyestuff is developed in a second bath with a diazonium compound.
- the process of the present invention includes the impregnation and developing stage in one bath, and after a period necessary for fixing the coupling component coupling takes place without any intervening operation so that the duration of such a dyeing process is essentially reduced.
- German Patent 1,057,061 teaches a process for producing water-insoluble azo dyestuffs on vegetable fibers by treating the said fibers at a long goods-to-liquor ratio in a bath containing a coupling component and a diazoor tetrazoamino compound without solubilizing groups and developing the azo dyestufi by treatment in an acid bath.
- the process according to the invention which is carried out with the use of substantive coupling components and diazoaminoor tetrazoamino compounds from diazotized aromatic monoor diamines and cyanamide, is distinguished in that the dyestuffs can be developed at low temperatures and an elevation of the temperature after the addition of acid is not necessary.
- a further advantage of the present process resides in the fact that the diazoamino or tetrazoamino compounds with cyanamide are present as stabilizers in the alkaline bath in the form of dissolved alkali metal salts whereby a complete penetration of the material to be dyed is achieved resulting in a quantitative coupling, whereas with the use of water-insoluble diazoamino compounds the latter are superficially deposited on the material to be dyed, which may result in an incomplete penetration of the dyestutf.
- a re-coupling of the diazonium compound with the cyanamide cannot take place because on splitting neutral salts and urea are formed in addition to the diazonium compound. In this manner the dyestufi components used are fully utilized.
- EXAMPLE 1 A cross-wound bobbin of 500 grams of cotton yarn was treated in a dyeing machine having a content of about 6 liters for 30 minutes with a solution of 20 C, (circulation towards the outside) containing in about 5.8 liters of water 8.1 grams of the diazonium compound of diazotized l-amino-Z,S-dichlorobenzene and sodium cyanamide and 3 grams of the sodium salt of ethylene diaminetetracetic acid with dc-aeration of the core of the bobbin.
