Abstract [eng] The change of tanning parameters reflects on leather chemical and physical properties. The standardized determination methods of more important for customers leather indexes do not allow absolutely clear to conclude about suitability of developed tanning method for leather processing. Due to this DSC analysis and IR spectroscopy were employed as additionally analyses methods for the clarification of tanning process influence on leather qualitative properties. During research established structural characteristics of variously tanned leather show how differently tanning materials join to derma collagen and prove that content of linked tanning materials is not most important factor, which ordains the thermo stability of collagen, in the case of chrome-free tanning. The results of DSC and IR-spectroscopy clarify the data obtained by other investigation methods and allow more exactly estimation of the tanning method suitability for leather processing. It was established that variation of vegetable tannins in tanning recipe influences on leather properties and best results are obtained using mimosa tannins.
