摘　　要：通过对不浸酸铬鞣剂 C- 2 0 0 0溶液的耐碱稳定性、不同电荷的铬配合物的组分随陈化时间的变化规律及鞣制过程中皮内 p H值及皮收缩温度随鞣制时间的变化规律的研究 ,对不浸酸铬鞣机理进行了初步探讨。The stability to alkli and the distribution of chromium complex of solution of chrome tanning agent without pickling were studied,which are varied with the aged time. At the same time, the change of pH value in different layer of leather and shrinking temperature of leather are measured during no-pickling chrome tannage. Based on the results, the tanning mechanism of no-pickling chrome tannage is explained.
