Abstract

The main objective of this research is to validate the application of a recently developed isometric method for determining the resistance to denaturation of leather tanned with different vegetable extracts. The results obtained for shrinkage temperature and denaturation temperature are similar to those obtained by methods based on ISO 3380 (traditional) and Differential Scanning Calorimetry (DSC). The isometric method also allows evaluating the evolution of hydrothermal breakdown of the different types of collagen (leather) – tannin (vegetable tanning extract) bonds as a function of the thermal increase to which the leather is subjected. It is concluded that, with the isometric method, and for leathers tanned with vegetable extracts, much more comprehensive information is obtained about the denaturation process of vegetable-tanned leather than with the traditional method, without requiring significant investments as in the case of the DSC method.

用等距法研究用植物提取物鞣制的皮革的水热稳定性

这项研究的主要目的是验证最近开发的等距法在测定用不同植物提取物鞣制的皮革的抗变性能力方面的应用。所获得的收缩温度和变性温度结果与基于 ISO 3380（传统）和差示扫描量热法（DSC）的方法所获得的结果相似。等压法还可以评估不同类型的胶原蛋白（皮革）-单宁（植物鞣制提取物）键的水热分解演变情况，并将其作为皮革所受热量增加的函数。结论是，对于使用植物提取物鞣制的皮革，使用等压法可以获得比传统方法更全面的有关植物鞣革变性过程的信息，而无需像使用 DSC 方法那样进行大量投资。

期刊介绍： Thermochimica Acta publishes original research contributions covering all aspects of thermoanalytical and calorimetric methods and their application to experimental chemistry, physics, biology and engineering. The journal aims to span the whole range from fundamental research to practical application. The journal focuses on the research that advances physical and analytical science of thermal phenomena. Therefore, the manuscripts are expected to provide important insights into the thermal phenomena studied or to propose significant improvements of analytical or computational techniques employed in thermal studies. Manuscripts that report the results of routine thermal measurements are not suitable for publication in Thermochimica Acta. The journal particularly welcomes papers from newly emerging areas as well as from the traditional strength areas: - New and improved instrumentation and methods - Thermal properties and behavior of materials - Kinetics of thermally stimulated processes
