Method of dyeing with reactive dye

A method of dyeing with one or more reactive dyes either a single material selected between polyamide fibers and cellulose fibers or a composite material comprising a material selected among synthetic polyamide and natural polyamide fibers and a material selected among cellulose, polyacrylic, and polyester fibers, characterized in that the reactive dyes are selected based on a classification of reactive dyes by the ratio of the color density of dyed synthetic polyamide fibers to that of cellulose fibers dyed in the same bath as the synthetic polyamide fibers and on color differences for correction, and that the work is dyed with the reactive dyes or with a combination of the reactive dyes and one or more dyes selected among metal-containing acid dyes, disperse dyes, etc., all the dyes to be used being dissolved in a single bath.
