By reacting tetrazine and triazine groups with chromophores of three different dyes (Reactive blue 4, orange 1 and red 2), monochlorotetrazinyl and dichlorotriazinyl dyes were synthesized. Coloring efficiencies were investigated by dyeing cotton fiber with these dyes at different temperatures. Exhaustion and fixation yields were determined by analysis of washing waters containing waste dye. Comparation of results showed that exhausting and fixing efficiencies of monochlorotetrazinyl dyes were lower than those of dichlorotriazinyl ones although they were generally closed to each other
By the reaction of tetrazine and triazine groups with the chromophores of three different dyes (reactive blue 4, orange 1 and red 2), monochlorotetrazinyl and dichlorotriazinyl reactive dyes were synthesized. Dyeing yield were examined by applying to cotton fibre with these dyes at different temperatures. Exhaustion and fixation rates (%) were determined by analysis of the washing waters containing waste dye. On comparing the results showed that the exhaustion and fixing efficiencies of monochlorotetrazinyl dyes were lower than those of dichlorotriazinyl dyes although they were generally close to each other.
