In the jig type textile finishing method and apparatus of the invention, the textile material (19) passes through a heated treatment bath (20) and is rolled alternately in one direction and in the opposite direction with high frequency or microwave electromagnetic waves (24) being applied to said textile material (19) while it is being rolled in and/or out. The power of the waves is determined, as a function of the optimum temperature for the reaction that is to be implemented, in such a manner as to maintain the temperature of the assembly (5, 6) constituted by the rolled-in textile material and the bath in which it is impregnated substantially equal to or greater than said optimum temperature.

A resonant high-frequency or micro-wave applicator for the thermal treatment of a flat material is disclosed. This applicator comprises a flat capacitor between the plates of which the material moves and an inductor which is constituted by a metal band extending transversely the plate acting as hot electrode. The inner face of the plate acting as ground electrode is divided into elementary sections by an assembly of longitudinal grooves. Preferably, the same applies to the inner faces of the plate acting as hot electrode and the inductor.
