以皮粉和浸酸皮为原料，研究了胶原蛋白与二羟基萘类（DHN）或二酚类与恶唑烷类的鞣制反应。这项研究表明，一些DHN对胶原蛋白有晒黑作用。胶原上的结合和交联的DHN的测量显示30-40%的1，6-和2，6-DHN通过共价键合固定。结果表明，未结合的DHN经脱鞣后，皮革的收缩温度变化不大，说明结合鞣皮革的高稳定性来自于DHN与胶原之间通过恶唑烷形成的共价键。
Leather tanning reactions between collagen and dihydroxynaphthalenes (DHNs) or diphenols and oxazolidine have been investigated using hide powder and sheepskin pickled pelt. This investigation showed that some DHNs have a tanning effect on collagen. The measurement of combined and cross-linked DHNs on collagen showed that 30-40% 1,6- and 2,6-DHNs were fixed through covalent bonding. Shrinkage temperature of the leather changed little after the non combined DHNs had been removed from the leather, indicating that the high stability of the combination tanned leather comes from the covalent bonding formed between DHNs and collagen through oxazolidine.
