In order to improve the solubility of this dyestuff in alkali liquor, the right dispersants will be needed. A series of condensates are synthesized by changing the synthesis conditions such as the ratio of naphthalenesulfonic (N) to formaldehyde (F), acidity, and their compositions are confirmed by MS spectrum. It is found that in acidity scope of 20%-24% and the ratio of N to F 1∶0.33, the synthesized condensates can efficiently improve the solubility of C.I. reactive blue 19 in alkali liquor. In addition, the influences of the condensates on the exhaust dyeing and the cold pad-batch dyeing are tested.展开更多
