Abstract
333,236. Wilson, J. S., Beckett, E. G., Thomas, J., and Scottish Dyes, Ltd. Feb. 2, 1929. Dye preparations. - Dry powders of anthraquinone acetyl silk dyestuffs are prepared by mixing the dyes in the form of aqueous paste with alkali soaps of higher fatty acids and subsequently drying at temperatures not higher than 50‹. Other dispersing or solubilizing agents may be admixed either during or after the above process. According to examples, (1) a paste of Duranol Blue CB is mixed with a neutral soap and dried at a low temperature, (2) a paste of Duranol Orange G is mixed with an alkaline soap, dried in vacuo at 50‹ C., powdered and ground, and (3) a paste of Duranol Red 2B is mixed with dry soap and soda ash, and dried, either in vacuo or in a stream of air, at 50‹ C. Both ordinary and dispersed pastes, containing saponin, sulphite cellulose waste liquor, formaldehyde-naphthalenesulphonic acid condensation products, or naphthalene sulphonic acids may be used. Specifications 211,720, [Class 15 (ii), Dyeing, Processes &c. for], 219,349 and 224,925 are referred to.
