摘要
采用DMT-ⅡB无铬多金属配合鞣剂分别对1#有机鞣剂和2#有机鞣剂所鞣得的水牛二层坯革进行复鞣,即进行无机/有机无铬结合鞣,并进行湿态染整操作。试验工艺获得的水牛二层沙发革检测后发现,DMT-ⅡB配合鞣剂复鞣1#有机鞣剂鞣坯革制得的革收缩温度达到89.1℃,复鞣2#有机鞣剂鞣坯革制得的革收缩温度达到86.3℃,再经过湿态整理和干整理后收缩温度分别达到92.5℃和86.4℃,革身丰满柔软,撕裂强度和抗张强度较好。综合比较分析表明,DMT-ⅡB配合鞣剂与1#有机鞣剂结合鞣制得的成革综合性能较优。
The DMT-ⅡB chrome-free polymetallic tanning agent was applied in the buffalo hide split crust which was tanned by 1# organic tanning agent or 2# organic tanning agent. Post-tanning operations were also carried out. The properties of the buffalo hide split sofa leather after these processes were tested.The results showed that the shrinkage temperature of the leather followed by DMT-ⅡB retanning after 1#organic tanning was 89.1 ℃, while the other was 86.3℃. The shrinkage temperatures of the two kinds of leather can reach 92.5 ℃ and 86.4 ℃ after wet and dry finishing, respectively. The resultant leathers are full and soft, and have better tearing resistance and tensile resistance. Comprehensive°properties of leather that was combination-tanned using DMT-ⅡB tanning agent and 1# organic tanning agent were superior to that of the other.
