数年間にわたって褪色しない。(Function) In the method for dyeing rushes of the present invention, as shown in Fig. 1, when a copper dye B containing a small amount of iron is added to an acidic aqueous solution A in which an organic acid is dissolved and heated, the copper and organic A chemical reaction with the acid results in foaming, and the aqueous solution A is colored green. Because the Igusa C is heated at 90℃ or higher for at least ten minutes or more, the Igusa C is evenly dyed in a clear green color, and the green color does not fade for several years due to the fixing effect of the iron contained in the dye. .

Further, if the heating time of the rush is about 10 minutes, the rush will not be dyed in a uniform color.
