Abstract

Cellulosic textile materials are dyed on the foulard or printed with a dyestuff containing at least one solubilizing group and at least one labile substituent, such as a halogen atom, or a sulphuric or phosphoric acid ester group or a sulphonyloxy group, which is bound to a carbon atom of the aliphatic chain of an alkyl-sulphone residue which is present in the dyestuff molecule, and the dyestuff is fixed on the fibre by steaming in the presence of inorganic acid-binding agent, such as an alkali-metal hydroxide, carbonate, phosphate, borate, perborate, an alkaline-earth metal hydroxide, potassium cyanide or mixtures thereof. Suitable dyestuffs are of the stilbene, azine, dioxazine, anthraquinone, phthalocyanine and azo (including metal-free and metalliferous azo) series. The dyeing liquor or printing paste may contain neutral inorganic salts such as alkali metal chlorides and sulphates. The printing paste may contain urea and the usual thickeners. The acid-binding agent may be added to the dyestuff liquor or paste, or the impregnated or printed material may be subsequently treated with the acid-binding agent prior to the steaming step. As an alternative, a substance such as sodium bicarbonate, which yields an acid-binding agent on heating, may be added to the dyestuff liquor or paste. When the dyestuff contains metallizable groups, the dyeings or prints may subsequently be metallized. Numerous examples are given in which the following dyestuffs are employed:- <FORM:0867546/IV(c)/1> Specifications 733,471 and 740,553 are referred to.
