摘　　要：铬鞣革分别采用8类共19种典型复鞣剂复鞣，并用两亲聚台物复鞣加脂剂处理，对所得革的吸水度进行了对比研究。结果表明，用植物鞣剂、代替型合成鞣剂和乙烯基单体聚台物复鞣的革，其吸水度无明显变化；用甲醛和戊二醛复鞣，革的防水性有所提高；用辅助型合成鞣剂和矿物鞣剂复鞣，革的防水性明显降低；含铬钼改性栲胶和含铬合成鞣剂则使复鞣革的防水性显著降低。Chrome leather retanned with ig kinds of typical retanning agents, which were classified into 8 groupsaccording to chemical constitution, and processed with amphiphilic copolymers for retanning andfatliquoring. The water absorption of the resultant leather retanned with vegetable tanning agents, alterable syntans and vinyl copolymers did not change obviously. The waterproofness of that those retanned with formaldehyde and glutaraldehyde increased, that those retanned with auxiliary syntans andmineral tanning agents decreased greatly, and that retanned with modified vegetable tannin extracts containing chromium decreased.
