摘要/Abstract

摘要： 以绵羊酸皮为实验对象,使用新型有机鞣剂艾力特AT分别在常规浸酸和不浸酸两种工艺体系下进行鞣制,通过坯革的收缩温度、纤维形貌及其热力学性能等分析测试,主要考察艾力特AT鞣剂在浸酸与不浸酸工艺体系下鞣制性能的差异性。实验结果表明:在两种工艺体系中,鞣制工艺条件的变化对鞣制效果产生了相似的影响;在艾力特AT鞣剂用量6%时,两种不同工艺体系下鞣制的坯革收缩温度都可以达到89 ℃。此外,鞣制坯革粒面饱满,毛孔清晰,热稳定性和力学性能基本接近。因此,艾力特AT鞣剂在浸酸与不浸酸工艺条件下,基本鞣制效应差异性不明显,这对于推广和应用基于艾力特AT鞣剂的无铬鞣制技术具有一定的理论指导意义。

Abstract: This study aimed to investigate the tanning performance of a newly organic chromium-free tanning agent, EIT AT. The pickled sheepskins were used in the experiment. By using two different tanning systems: conventional pickling and non-pickling, the shrinkage temperature, fiber morphology, and thermodynamic properties of tanned leather were analyzed. The results showed that the change of variations in tanning process has a similar impact on the tanning effect in two different tanning systems. At the 6% amount of EIT AT, the shrinkage temperature of the crust leather can reach above 89 ℃; The crust leather exhibited full grain and clear pores, as well as similar thermal stability and mechanical properties in two different tanning systems. Therefore, the tanning effect of EIT AT tanning agent shows less differences with pickling or non-pickling conditions. The results provide a certain theoretical guidance for the popularization and application of chromium-free tanning technology with EIT AT tanning agent.

Key words: EIT AT, chromium-free tanning agent, chrome-free tanning, leather manufacture
