The product is immersed in the dyeing bath (13), where one thousandth part of coloring material is dispersed in twice the quantity of water; both calculated with respect to the quantity of product. With respect to the quantity of dye, a one-hundredth part of dispersant is included. The dyed product is irradiated by microwaves (10). The water is extracted, such that about 80 wt.% of dye remains in solution. The temperature is increased to about 130 deg C, followed by drying at about 100 deg C. An Independent claim is included for the corresponding plant. Preferred features: The product is immersed for about 10 minutes. Drying in microwaves takes about 5 minutes. In a continuous process, the solution is poured into the bath in quantities which are fully expended. The cloth is continuously supplied and immersed, using rollers (1-5). Further rollers (7, 7') squeeze out the liquid, leaving about 80-100% with respect to the dyed product. The product is continuously extracted over synchronized rollers, for drying.
