Abstract

Dyeings, e.g. on wool, cotton, silk, rayon, or leather or on mixed fibres, are fixed by treatment with an aqueous composition comprising a salt of a bi- or poly-valent metal, a second salt of a bi- or poly-valent metal and an agent binding mineral acid. Alternatively, the second salt, e.g. a basic chromium sulphate, may itself serve as the acid-binding agent. In all cases the proportions are such that the second salt counteracts change of shade produced by the first salt. Specified cations of the salts are copper, lead, cadmium, mercury, bismuth, tin (stannous and stannic), iron (ferrous and ferric), zinc, nickel, cobalt, calcium, barium, magnesium, aluminium, chromium, titanium and cerium, and specified anions are sulphate, basic sulphate, chloride, nitrate, fluoride, acetate, formate, tartrate, citrate, tungstate, chromate, dichromate, carbonate, borate and hydroxide. Specified agents binding mineral acid are soda ash, borax, sodium and calcium acetates and sodium formate. The presence of a small quantity of a citrate or tartrate, e.g. potassium bitartrate, argol or Rochelle salt improves the evenness and penetration, and the presence of common salt or Glauber's salt prevents diffusion of the dye from the fibre. Specified aqueous compositions contain: (1) aluminium sulphate and calcium acetate; (2) the same with common salt; (3) aluminium sulphate, basic chromium sulphate and common salt; (4) the same with calcium acetate; (5) and (6) aluminium sulphate, basic chromium sulphate, common salt, calcium acetate and argol; (7) aluminium sulphate, calcium acetate, basic chromium sulphate and argol; (8) and (9) aluminium sulphate, calcium acetate, tartaric or citric acid and common salt. Acetic or formic acid is advantageously added to the fixing liquor before use. The dyed material is preferably passed through a cold solution of common salt and the aqueous fixing liquor is then applied at 70-110 DEG F. for 15-20 minutes and the excess of fixing agent is washed out. The Specification as open to inspection under Sect. 91 comprises also (1) the use as fixing agents of acids and of salts of monovalent cations such as silver, sodium or potassium, (2) the use of a fixing composition containing aluminium sulphate, soda ash and common salt. This subject-matter does not appear in the Specification as accepted.
