Gorbachov A. Scientific fundamentals of technological processes of leather manufacture and derivatives of collagen as concerning thermodynamics.

As a result of complex researches of physical-chemical influences of various substances on collagen as concerning thermodynamics the scientific fundamentals of technological processes leather manufacture and derivatives of collagen have been worked out that allowed to find the new technical decisions of converting derma into leather. The functional dependence in leather area yield on physical-chemical indices and dzeta-potential has been theoretically deduced and proved. The phenomenon of solubilization of hydrocarbon in leather as a factor defining the volume of disordered zone structure of collagen derma and the package density of triple spirals in ordered zone has been examined. The concepts and the characteristics of boundary surfaces between ordered and disordered zones of collagen structure. The methodology of creating leather technology and derivatives of collagen has been worked out. The thermodynamic fundamentals allow to develop resources saving technologies properties of the finished products.
