• ABSTRACT Process for the single-bath dyeing of cellulose fibers and their mixtures with synthetic fibers with waterinsoluble azo dyestuffs produced on the fiber according to the exhaustion method, wherein an aqueous dyebath is allowed to act on the textile material, at room temperature or moderately elevated temperature, which liquor contains, in addition to alkaline substances, sodium nitrite and an anionic dispersing system, the solution or dispersion of at least one component capable of .entering into azo coupling and at least one non-diazotized primary aromatic amine in a medium on the basis of a water-miscible organic solvent or solubilizer, and after absorption of the coupling component, the diazotization of the amine and the dyestuff formation by coupling is caused in that acid or acid salts are added to the dyeing bath at room temperature.
• the present invention concerns a process for the single-bath dyeing of cellulose fibers or mixtures thereof with synthetic fibers with water-insoluble azo dyestuffs produced on the fiber by the exhaustion method.
• German Pat. No. 729,846 describes a process wherein, within the scope of the calico printing of cellulose fihers, both the coupling component and the diazotable primary aromatic amine in one printing paste is printed on the goods together with the sodium nitrite and the az'o dyestuff is then developed by a passage through an acid; A further process is known from German Pat. No.
• 1,262,957 according to which coupling components are applied on the textile material according to the exhaustion method in a single bath with stabilized dior tet razoamino compounds of primary amines which are resistant to alkalies and the dyestuff is developed on the fiberby adding an acid to the bath.
• the present invention is based on the observation that cellulose fibers and their mixtures with synthetic fibers, preferably polyester fibers, can be dyed according to the exhaustion method in a single bath with water-insoluble azo dyestuffs produced on the fiber if an aqueous liquor is allowed to act on the textile material, at room temperature or moderatelyelevated temperature, which liquor contains, in addition to alkaline substances, sodium nitrite and an anionic dispersing system, the solution or dispersion of at least one component capable of entering into azo coupling and at least one non-diazotized primary aromatic amine in a medium on the basis of water-miscible organic solvent or solubilizer and after absorption of the coupling component, the diazotization of the amine and the formation of the dyestuff by coupling on the fiber are then effected by adding acid or acid salts to the dyeing bath at room temperature.
• the primary aromatic amines which are water-insoluble in an alkaline medium are made clearly soluble or prefectly dispersible by means of suitable means in order to keep the dyebaths stable without any precipitations both in the impregnating phase within the alkaline range and in the developing phase within the acid range.
• suitable solvents and a dispersing system which is effective in both process steps.
