摘　　要：黑色人发的漂白过程中,采用亚铁离子对人发中的黑色素进行络合,进而达到催化双氧水分解是实现人发漂白的重要环节。文章对该络合催化过程中的催化剂和络合剂用量,催化反应温度及时间对毛发漂白后的白度及强力性能的影响进行了分析和研究。结果表明,络合催化过程的最佳条件为浴比1∶10、草酸25 g/L、FeSO414g/L、NaCl 30 g/L,保温温度90℃,保温时间180 min。在此条件下,毛发的白度值达到31.5,强力性能为110 cN,能够很好地满足发制品企业对漂白工艺的实际生产要求。In the hleaching process of black human hair, the using of ferrous ion to complex of melanin, then achieves the catalytic decomposition of hydrogen peroxide is the important link to realize human hair＇s bleaching. This paper analyzed and studied the effect of the dosage of catalyst and complexing agent, temperature and time in the process of catalyst on the bleaching hair＇s whiteness and strength. The results showed that the best condition of complexing catalytic process was ： bath ratio 1 ： 10, oxalate 25 g/L, FeSO4 14g/L, NaCl 30 g/L, heat preservation temperature 90 ℃, holding time 180 min. Under this condition, the whiteness of hair can reach 31.5, the breaking strength can reach 110cN, which can well satisfy the enterprises to bleaching process of practical production requirements.
