摘　　要：采用4种商品砜类合成鞣剂进行鞣革试验,以坯革收缩温度、鞣剂吸收率为评价指标,分别对鞣剂用量、鞣制终点p H、鞣制时间进行考察,确定了这几种鞣剂单独使用的最佳工艺条件;进一步对比了各鞣剂鞣制坯革的收缩温度、撕裂强度、断裂伸长率、耐光性等性能,并得出了用BC砜类合成鞣剂,可获得较好的综合鞣制效果。研究结果表明:用砜类合成鞣剂单独鞣革,对皮胶原收缩温度的提高有限,还需改性或与其它鞣制材料结合用于皮革鞣制。Four kinds of commercial sulfone synthetic tanning agents were used for tanning experiments. The shrinkage temper- ature （Ts） of crust leathers and the uptake of tanning agents were examined to determine the optimum tanning conditions, such as the effects of dosage, final pH in tanning float and tanning time. By analyzing the Ts, tearing strength, elongation at break and light -fastness of the crust leathers tanned at optimum tanning conditions, it shows that sulfone syntan BC has better tanning properties. However, solo - sulfone synthetic tanning seems insufficient for the improvement of Ts. Therefore, it needs further modi- fication or combination with other tanning agents.
