阳离子明胶蛋白助剂对双氧水分解率的影响

摘要

For the purpose of improving the control of the hydrogen peroxide decomposition rate, the prediction of the bleaching results, and the optimization of cotton fabric bleaching process, a self-made cationic gelatin protein agent was used in cotton hydrogen peroxide bleaching and hydrogen peroxide decomposition rate was calculated. The influence of self-made cationic gelatin protein agent, stabilizing agent sodium silicate and activator TAED on the hydrogen peroxide decomposition rate was compared. The results showed that cationic gelatin protein could promote the decomposition of hydrogen peroxide effectively and the decomposition rate was closed to TAED under low temperature and low alkali. The cationic gelatin protein acted as an activator in bleaching process. It provided a theoretical basis for the cationic gelatin protein agent application in hydrogen peroxide bleaching with low temperature and low alkali.%为提高对棉织物漂白过程中双氧水分解速率的控制、漂白效果的预测及漂白工艺优化的理论指导作用，将自制的阳离子明胶蛋白助剂应用于棉织物双氧水漂白工艺中，计算双氧水分解速率，并与传统稳定剂硅酸钠及活化剂TAED对双氧水分解速率的影响对比。结果表明，在低温低碱条件下，阳离子明胶蛋白能有效促进双氧水的分解，分解率与TAED相近，说明阳离子明胶蛋白助剂在双氧水漂白过程中起到活化剂的作用，从而为阳离子明胶蛋白助剂在双氧水低温低碱漂白中的应用提供理论依据。
