No. CCXXIII.This invention consists in manufacturing mixtures of the following materials, to be used in dyeing woollen fabrics, or fabrics containing a mixture of wool, viz.: — Sulphuric, nitric, boracic, acetic, arsenious, pyroligneous, oxalic, and tartaric acids—chloride of sodium or common salt—sal-ammoniac— chloride of magnesium—chloride of potassium—sulphate of potash—sulphate of magnesia—sulphate of soda—oxalate of potash—acetate of potash—acetate of soda—nitrate of soda— nitrate of potash—sulphate of zinc — and borax.
The patentee describes seven mixtures, which are those that he prefers to use; but he does not confine himself thereto, as variations in the proportions or substitutions of certain of the materials above enumerated may be made. The first mixture consists of 100 parts of chloride of sodium, 300 parts of water, 10 parts of sulphuric acid, 3 parts of nitric acid, and 1 part of arsenious acid. The second mixture consists of 100 parts of sulphate of soda or sulphate of potash, 6 parts of sulphuric acid, and 2 parts of nitric acid. The third mixture consists of 100 parts of sulphate of soda or potash, 1 part of sulphuric acid, 3 parts of nitric acid, and 6 parts of vinegar (or, instead of the latter, 2 parts of purified acetic acid may be used). The fourth mixture is composed of 100 parts of sulphate of soda or potash, 6 parts of sulphuric acid, and 3 parts of tartaric acid in a state of powder. The fifth mixture consists of 100 parts of nitrate of potash, 30, 40, 50, or 60 parts of sulphuric acid (according to the shade required), and 1000 parts of sulphate of soda or potash. The sixth mixture is composed of 100 parts of the fifth mixture, 3 parts of tartaric acid in a state of powder, and 10 parts of acetate of potash. The seventh mixture consists of 100 parts of sulphate of soda or potash, 4 parts of nitric acid, 4 parts of acetic acid, and 10 parts of tartaric acid in a state of powder.
The first and second mixtures are not to be employed for grain colors, or for any other colors in which solutions of tin are present; but the other mixtures may be employed for all colors,—including grain colors, or other colors in which solutions of tin are present. The materials of which the mixtures are composed are to be left in contact for several days. The vessels in which the above mixtures, or other analogous compounds, are prepared, must be formed of such substances as will not be liable to be acted on by the materials that are to compose the mixture; and which materials are allowed to act on each other until decomposition and admixture are thoroughly effected. The mixtures may be dried by natural or artificial means, and reduced to a state of powder in a mortar or mill.
The mixtures, above described, are to be used in dyeing woollen fabrics, or fabrics in which a mixture of wool is present, in the same manner as cream of tartar or argol is commonly employed,—the same weight of the respective mixtures being taken as would have been taken of cream of tartar or argol. The mixtures are to be employed with the aluminous or other mordants in the ordinary operations of dyeing. For dyeing dark colors, the mixtures may be used without the addition of other mordants; but, for ordinary purposes, they are employed as substitutes for cream of tartar or argol. In conclusion, the patentee says that, having described the invention and stated what he considers to be the best materials for the purposes above mentioned, he wishes it to be understood that he does not claim the use of the acids or salts above enumerated, when taken separately; but he does claim, as the improvements in dyeing and dyeing materials communicated to him, the use of such acids and salts, when combined in the manner and for the purposes above described, or when any of them are made to substitute one another in such mixtures for like purposes. — [Inrolled May, 1850.]
