| abstract | Animal or vegetable fibres are dyed by oxidizing phenols, amines or their salts by means of persulphate together with a metallic salt or oxide. The medium may be acid, neutral, alkaline, ammoniacal or pyridine may be added. In the case of an alkaline medium a substance, such as Seignette salt, sugar, or glycerine, is added to prevent precipitation. Suitable phenols and amines are phenol, diaminophenol, p-aminophenol, hydroquinone, catechol, resorcin, diamino-and dinitroresorcin, pyrogallol, tannins, and extracts containing them such as oak, chestnut, willow, sumae, birch, quebracho and catechu, aniline for example as aniline oil, p-toluidine, m-phenylenediamine, a - and b -naphthylamines and benzidine. Examples are given using the above reagents to give yellows, reds, browns, greens, blacks, violets and grays in conjunction with salts, such as sulphates, of copper, nickel, cobalt, iron (as ferrous or ferric), vanadium, zinc, and magnesium. Two or more salts may be employed together, as well as two or more tannins or an amine and a phenol, for example m-phenylenediamine and tannin, to give different shades or the metals may be employed in their various stages of oxidation. The oxidation may be carried out either in the cold or with application of heat. Polychromatic effects may be obtained by printing a ground colour, produced as described above, with a thickened metal powder, salt or oxide. Specification 11451/03 is referred to. |
