Abstract

Reactive dyestuffs present on textile materials are fixed thereon by exposing the said materials to the action of a high-frequency electric field in such a way that its surface area is small in relation to its volume. The textile material is preferably at least 10 cm.thick in such forms as rolled up or zig-zag folded fabrics, wound packages or compact piles or yarns or sliver possibly wrapped in aluminium foil. The electric field may be generated in known ways and may be a capacitive field or one produced by introducing high-frequency oscillations into an electrically sealed chamber which, advantageously, has metal walls of good conductivity and thus reflecting properties. The high-frequency oscillations may be generated by a magnetron and introduced into the chamber by means of rectangular or cylindrical hollow conductors or a coaxial conductor. In the examples the latter method is used, the chamber being a metal oven and the magnetron providing high-frequency energy of frequency 2400 mc. (wavelength = 12.5 cm.). The reactive dyestuffs suitable for the present process are preferably water-soluble and contain at least one reactive group (many specified) and may be from the oxazine, triphenylmethane, xanthene, nitro, acridone, azo, anthraquinone and phthalocyanine series; reactive disperse and vat dyes may also be used especially vat dyes containing water-solubilising groups in which case the presence of a reducing agent is normally of advantage. The dyestuffs are applied in the usual way, e.g. by p padding or printing, and, when the textile materials are of cellulose, together with an acid-binding agent. Agents which assist the fixation, e.g. 1 : 4-diazo-bicyclo-(2 : 2 : 2)-octane and hydrazines that contain at least one 3 degrees nitrogen, may also be included. The dye-impregnated materials may be treated with the high-frequency electric field in either the wet or the dry state and the time of treatment in the Examples is 2-5 minutes. Fabrics of cotton, linen and viscose staple and sliver of viscose staple are dyed in the examples.
