摘要
借助差热分析法（ＤＳＣ），研究了未鞣制的浸酸生皮及经聚合物鞣剂鞣制后的皮革所显示的皮胶原热变行为的变化；指出了助鞣与自鞣性鞣剂对胶原作用的本质区别；讨论了鞣剂对胶原的相互作用及其影响，利用胶原结构的“核壳”理论及“结晶”理论讨论了在鞣制过程中胶原纤维结构与分布状态的变化。
In this article the veriation of thermol denaturation behaviour of collagen by means of DSC spectra,which include the pickling skin and the pickling skin tanned by verious acrylic polymer tanning agents,have been investigated.The essential distinations on reacting with collagen molecules between self-tanning agent and auxilloury tanning agent have been indicated.Furthermore the tanning agents above on collagen structure,have been discussed.With help of the 'shell-core' theory'and 'crystal theory' of colagen structure ,the veriation of structure and distribution state of collagen fiber by the process of tanning have been discussed.
