A dye-fixing process which follows the treatment of lengths of materials containing synthetic fibers, such as polyester and polyamide fibers, with dyes, including dispersion dyes, said process comprising the steps of heating a dried dye-carrying length of material with pure steam or a steam-air mixture containing over 75 percent steam by volume by condensation of steam to a saturation temperature of substantially 90 DEG to 100 DEG C., then heating said length of material with media having heat-transmission values of at least 50 k. cal./m2/ DEG C. /h. by a heating curve which is a continuously increasing temperature of the fabric and which approaches asymptotically and then reaches a fixing and treating temperature of at least 150 DEG C., the heat flux being determined by measuring temperatures, duration, length surfaces as well as average flow amounts and speeds, and then subjecting the material to a continuous thermostorage treatment at said treating temperature for a time period ranging between 10 and 100 seconds.
