摘　　要：本文涉及了稀土－植物鞣剂的化学研究．鞣法研究及革的物理机械性能。单独稀土鞣革的收缩温度为62℃．植鞣的收缩温度为83℃，而两者结合鞣为102℃，并且这种结合鞣革有良好的手感及强度。研究表明这种结合鞣在制革工业中有重要的现实意义。This paper involves the studies of chemisty and technology on combination tanning of rare earth - vegetable tanning extract and physical - mechanical properties of the combination tanning leather. The leather tanned with rare earth has a shrinkage temp, 62℃ and 83℃ with vegetable tanning extract and then 102℃ with rare earth - vegetable tannin extract.The combination tanning leather has also good handle and strength. The results show that this kind of combination tanningmethod has practical value in leather industry.
