【 摘 要 】

The processes of accelerated artificial aging and sweat action of leather parchment manufactured in different methods from sheep's skin were investigated. By means of standard physical and mechanical methods of analysis and method of gel electrophoresis, the effect of high temperature and sweat was analysed on the behaviour of this biopolymer over time. The multidirectional of these influences on the most important physical and mechanical properties and the structure of parchment have been founds, which can be explained by the different degree of separation of the structural elements during the liming and the presence of plasticizing components that can prevent the influence of external factors.
