摘　要:固色劑是能提高染色和印花織物染色牢度的物質，隨著人們對紡織品的要求越來越高，我們急需開發(fā)和應用符合環(huán)保要求和環(huán)保指標的綠色固色劑。
以乙二醛為原料，在甲醛中與硫酸銨在85～90℃反應得產(chǎn)物，用熔點儀測產(chǎn)物的熔點，確定其產(chǎn)物為咪唑。再與環(huán)氧氯丙烷在25～30℃之間反應1～2h，溶液透明，有一定粘度后，再升溫至70～80℃，繼續(xù)反應5h，得到的產(chǎn)物中加入乙二胺，最后得淡紫色固色劑，進一步對固色劑的應用工藝性能進行了探討,經(jīng)測試固色后的織物的干摩擦牢度為4級，濕摩擦牢度為3級及耐水洗牢度效果一般,但這實驗設計合成簡單，成本便宜，適用于實際生產(chǎn)。表明這一實驗設計具有一定的研究價值，需要我們的進一步探索。

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.
