摘　　要：提出了针对鞣制及鞣后处理工艺合理化的研究。试验中合理利用软化后裸皮pH值高的特点,直接采用氨基树脂鞣剂预鞣,省去了浸酸和提碱。预鞣后削匀,然后采用一体化工艺,将传统工艺中的多个工序进行了有机整合,实现了铬鞣、复鞣、染色和加脂同浴操作。试验结果表明:试验工艺与对比工艺的成革性能相当。而前者的总化料和水的消耗量分别减少了40%和45.2%,总废水、悬浮物、COD负荷、BOD5负荷和色度,分别减少了53.84%、39.42%、58.04%、55.04%和90%。The rationalization of tanning and post - tanning processes in leather - making was studied. Based on the high pH value in bated hides, melamine resin was directly used for pretanning. That is, the conventional pickling and basifying processes were avoided. Then, by use of integrative technique, several processes in post - tanning processes were integrated effectively. As a result, chrome tanning, retanning, dyeing and fatliquoring processes were integrated in the same bath. The results indicate that the strength and functional properties of experimental leather have no significant difference with conventional leather. But the former has a obvious reduction in wastewater discharge, total suspension solids, COD load, BOD5 load. Chemical and water usage decrease by 53.84% ,39.42% ,58.04% ,55.04% ,40% and 45.2%, respectively.
