    Abstract: Textile materials, i.e. fibres, flocks, yarns, threads, woven and non-woven fabrics and films, comprising polymers of acrylonitrile or cellulose acetate are optically brightened by incorporating into the polymers or into the cellulose acetate, before or during the spinning of the textile materials, an azamonomethine cyanine compound of the formula in which Y and Y1 are identical or different and each represents a hydrogenation, a methyl group of a methoxy group and X is an anion, e.g. an inorganic anion such as a chloride, bromide, iodide, perchlorate or sulphate anion or an organic anion such as an alkylsulphate or arylsulphonate anion. From 0,01 to 5% of brightening agent, with reference to the weight of the material to be brightened, may be used. Cellulose acetate, the acetyl content of which lies between 2 1/2 and 3 groups per anhydro-glycose unit, and polymers of acrylonitrile and copolymers thereof with vinyl chloride, vinyl acetate or methyl methacrylate containing more than 50% by weight of acrylonitrile, may be treated. Specifications 447,038, 461,668 and 461,688 are referred to.ALSO:Fibres, flocks, yarns, threads, woven and nonwoven fabrics and films comprising polymers of acrylonitrile or cellulose acetate are optically brightened by treating them with an azamonomethine cyanine compound of the formula in which Y and Y1 are identical or different and each represents a hydrogen atom, a methyl group or a methoxy group and X is an anion, e.g. an inorganic anion such as a chloride, bromide, iodide, perchlorate or sulphate anion or an organic anion such as an alkylsulphate or arylsulphonate anion. The brightening agents are preferably applied from aqueous solutions in amounts such that 0.01%-5% of the brightening agent, with reference to the weight of the material to be brightened, is applied. The brightening process may be carried out before or simultaneously with an alkali metal chlorite bleach.

    Abstract: Keratinous fibrous material is simultaneously dyed and bleached at elevated temperatures using nonalkaline dye liquors containing wool dyes which are stable to peroxy compounds and any dye-bath assistants required, the dye liquor also containing hydrogen peroxide and/or performic acid in amounts equivalent to 0.7 to 10g/litre of active oxygen and 2 to 30 times the weight of active oxygen, of a polyphosphate. The term "polyphosphates" is defined as being salts of phosphorous acids containing two or more phosphorous atoms arranged linearly or in a network, and includes disodium dihydrogen pyrophosphate, tetraalkali metal pyrophosphates, alkali metal tripolyphosphates, tetrapolyphosphates and heptapolyphosphates. The Examples describe the application of the above dye liquors to wool. The Specification also refers to the simultaneous brightening or antifelting of the fabric during the dyeing process.
