Abstract
531,470. Dyeing cellulosic materials. SOC. OF CHEMICAL INDUSTRY IN BASLE. May 17, 1939, No. 14721. Convention date, May 18, 1938. [Class 15 (ii)] Substantive and mordant dyes, dyeing with.- In the production of dyeings on cellulosic materials with direct dyes capable of forming complex metal compounds which are soluble in water or in dilute 'alkali, the dyestuffs are treated during or after the dyeing process in a neutral or weakly alkaline medium not alkaline with caustic alkali, with an agent yielding metal, which agent contains the metal e.g. chromium, cobalt, nickel or copper, in complex union with an aliphatic aminocarboxylic or hydroxycarboxylic acid, e.g. aminoacetic, citric, malic or tartaric acid. Specified cellulosic materials are cotton, linen, ramie, hemp, jute and fibres, films or ribbons of regenerated cellulose, e.g. viscose and copper artificial silks. When the treatment is effected in the dyebath the agent yielding metal may be present from the beginning of the dyeing operation. In examples, (1) wetted-out cotton is entered into an aqueous dyebath at 40‹C. containing sodium sulphate and the dyestuff, anthranilic acid # 5:5<SP>1</SP>-dihydroxy-2:2<SP>1</SP>-dinaphthylamine - 7:7<SP>1</SP> - disulphonic acid - 5 - chloro- 2-aminobenzoic acid, the temperature is raised in 30 minutes to 90-95‹C. and so maintained for 15 minutes, whereupon a neutral solution of a tartrate containing copper in complex union is added and the temperature is maintained for a further 20-30 minutes and the goods are rinsed and dried to obtain a bluish red dyeing, fast to light ; (2) wetted-out viscose artificial silk is entered into an aqueous dyebath at 40‹C. containing sodium sulphate and the dyestuff, 5 - nitro - 2 - aminophenol # (alkaline) 2- phenylamino - 5 - naphthol - 7 - sulphonic acid, and the temperature is raised in 30 minutes to 80‹C., whereupon a glycocollate containing copper in complex union is added and the temperature is maintained for a further 15-20 minutes and the goods are washed and dried to obtain a blue-violet dyeing, fast to light; (3) wetted-out cotton is dyed as in (1) with replacement of the dyestuff therein by anthranilic acid (2 mols)<SP>#</SP> # 5:5'-dihydroxy-2:2'-dinaphthylurea - 7:7<SP>1</SP> - disulphonic acid (1 mol.) and with an addition of sodium carbonate to the dyebath to obtain a brownish red dyeing ; (4) wetted-out cotton is dyed as in (3) with replacement of the dyestuff therein by 2-aminophenol-4-sulphonamide (2 mols.) <SP>#</SP> # 5:5<SP>1</SP>-dihydroxy - 2:2<SP>1</SP> - dinaphthylamine - 7:7<SP>1</SP>- disulacid. They also yield lakes with complex phosphotungstic and/or phosphomolybdic acids. In examples, the following pairs of components are condensed together ; (1) phonic acid (1 mol.) to obtain a blue-violet dyeing fast to light ; the tartrate complex may be replaced by a diethanolaminoacetate, dimethylglycinate or α-alaninate containing copper in complex union ; (5) wetted-out cotton is entered into an aqueous dyebath at 40‹C. containing sodium carbonate and the dyestuff, 4-aminophenol-2-carboxylic acid # 1:7-aminonaphthalenesulphonic acid - 1:7-aminonaphthalenesulphonic acid - (alkaline) 2:5:7- aminonaphtholsulphonic acid, the temperature is raised in 30 minutes to boiling, sodium sulphate is added and boiling continued for ¢ hour, whereupon the dyeing is rinsed and treated for 30 minutes in a fresh bath of an aqueous solution at 50-60‹C. of a glycocollate, diethanolaminoacetate or diethylaminoacetate containing copper in complex union and rinsed to obtain a blue dyeing, fast to light; the fastness to washing may be improved by soaping in a fresh bath at 50‹C ; (6) wetted-out viscose artificial silk is dyed as in (2) except that the coppering is effected in a fresh bath with a tartrate containing copper in complex union; (7) wetted-out cotton is entered into an aqueous bath at 40-45‹C. containing sodium sulphate and the dyestuff, 4:4<SP>1</SP>-diaminodiphenyl-3:3<SP>1</SP>-dicarboxylic acid (1 mol.) <SP>#</SP> # (alkaline) 1-phenylamino-8-naphthol-4-sulphonic acid (2 mols.), the temperature is raised in 30 minutes to 90-95‹C. and so maintained for a further 30 minutes, whereupon the dyeing is rinsed and treated for 30 minutes in a fresh bath of an aqueous solution at 50-60<SP>o</SP>C. of a tartrate containing copper in complex union and the goods are rinsed, soaped, again rinsed and dried to obtain a green-blue dyeing, fast to light and washing. The processes claimed in Specifications 515,066, 515,099 and 516,076 are disclaimed. The Specification as open to inspection under Sect. 91 comprises also the use of metallizing agents containing the metal in complex union with amines, such as mono-di- and tri-methylamines and ethanolamine. This subject-matter does not appear in the Specification as accepted.
