The invention discloses a method for preparing active dye for blue wool. The preparation method comprises the following steps of: performing first condensation reaction on bromamine acid which serves as a raw material and phenylene diamine, and performing acid refining, sulfonation, second condensation reaction and aftertreatment to obtain the active dye. The method is advanced and low in cost and causes light pollution to the environment. The dye prepared by the method has bromo-acrylamide groups, and under a slightly acidic condition, by being used together with Sibagol B, the active dye has a high reactivity with wool and a high fixation rate and meets the 'machine washable' high fastness requirement of International Wool Secretariat, so the active dye is quite high in market competitiveness.

The invention discloses a reactive blue dye and a preparation method thereof. The preparation method comprises the steps as follows: 1) performing primary condensation, namely dissolving 2,4-diaminobenzenesulfonic acid and trichlorine triazine by water respectively and reacting to obtain a primary condensation product; 2) performing secondary condensation, namely reacting the primary condensation product with p-(beta-ethyl sulphone sulphate) phenylamine-o-sulfonic acid to obtain a secondary condensation product; 3) diazotizing, namely diazotizing the secondary condensation product to obtain a primary diazotizing solution; 4) performing primary coupling, namely diazotizing o-methoxy para-ester, reacting with H acid to obtain a primary coupling solution; and 5) mixing the primary coupling solution with the primary diazotizing solution and reacting to obtain the reactive blue dye. The invention further discloses the reactive blue dye prepared by the method, and the dye is good in deep dyeing ...
