摘　　要：用栲胶、铝鞣剂、钛鞣剂对浸酸猪皮进行结合鞣制,在最佳工艺的基础上,选取与铝鞣剂和钛鞣剂搭配最佳的栲胶,考察栲胶用量和改变结合鞣不同鞣制阶段pH值对Ts的影响。结果表明:使用水解类栲胶的效果一般情况下比用缩合类栲胶好,且用栗木栲胶的效果更好。在植铝钛结合鞣中,栗木栲胶用量15%,当植鞣pH值为4.8、铝鞣pH值为3.0、钛鞣pH值为1.5时,结合鞣制革的Ts达到93℃。The pickling pigskins were tanned with vegetable tannin, aluminium tanning agent and titanium tanning agent （ self - made）. On the basis of the optimum, the best collocation of tannin extracts was selected with aluminium tanning agent and tita- nium tanning agent. The effect of tannin extract dosage and different pH value in combination tanning process on Ts were investi- gated. The results show the tanning properties of the pelts by hydrolysable tannin are better than that by the condensed tannin on general circumstances, and chestnut extract tannin has a better tanning effect than other tannins. In the vegetable - alumium - ti- tanium combination tanning process, the amount of chestnut extract is 15%, when the pH value of vegetable tannage is 4. 8, the pH value of the aluminum tannage is 3.0, the pH value of the titanium taimage is 1.5, the maximum Ts value of the combination tanned leather can be up to 93 ℃.
