In order to solve the problems, researchers develop a series of novel substitute alkalis to replace traditional alkaline agents such as sodium carbonate and the like to be applied to reactive dye fixation. For example, chinese patent application No. 200610034187.2, "liquid dyeing alkali for reactive dye dyeing", discloses a liquid dyeing alkali SN composed of alkali metal hydroxide, alkali metal carbonate, alkali metal borate, organic carboxylate and water, which can be used for reactive dye dyeing with the amount of sodium carbonate 1/9, and has no dust pollution, the dyeing effect and various color fastnesses also reach the effect of sodium carbonate, but the preparation process is cumbersome, and the high temperature of 130 ℃ is kept, there is a production safety hazard; for example, the chinese patent with application number 201710151284.8, "a new substitute alkali and its preparation method", describes a new substitute alkali prepared from organic alkali, potassium carbonate, buffering agent and additive, the preparation process is simple, the fabric dyed and fixed by using it instead of soda has good color fastness, but the fabric leveling problem is not solved yet, which makes its application greatly limited.
