Abstract

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.

Claims9

Dependent claims

Textile finishing apparatus, comprising an enclosure in which the following are disposed:

a trough for an impregnating bath;
a system for rolling textile material in and out of the trough;
a feeder system enabling the textile material to dip into the bath;
and an electromagnetic wave applicator means suitable for applying electromagnetic waves to the textile material while it is being rolled in and out;
wherein the electromagnetic wave applicator means comprise at least one generator and at least one waveguide connected to said generator and opening out to the inside of the enclosure facing a shaft on which the textile material is to be rolled in as a roll, in such a manner as to ensure that the transmitted electromagnetic waves are directed towards the roll over the entire width thereof.
