Method of mordant dyeing of wool is described, including treatment in dye bath on the basis of complexing agent and dye for 40-60 min, besides dye used is aqueous extract of marsh-beet in amount of 5-50 % from wool mass. It is reasonable to perform the process first at ambient temperature for 12-24 hours, and then at 40-90°C for 40-60 min.
