Abstract: Fixing agent is able to improve the fastness of dyed and printed fabrics material, as people increasingly high demand for textile products, we need development and application of environmental compliance and environmental indicators of the green fixing agent. With glyoxal as raw material, formaldehyde and ammonium sulfate at 85 ~ 90 ℃ by the reaction product of the product by melting point melting point measuring instrument to determine their product is imidazole. Then with the reaction between epichlorohydrin in the 25～30℃ 1～2h, the solution transparent, have a certain viscosity, then heating to 70～80℃, continued to be 5h, the product obtained by adding ethylene diamine, and finally get lavender fixing agent, fixing agent for further application of the process performance is discussed, tested fabric after fixing the dry rubbing fastness is 4, the wet rubbing fastness and washing fastness of 3, the general effect, but this experiment Design and Synthesis of simple, low cost, suitable for actual production. Suggest that this experimental design has some research value, we need further exploration.
