Deformation properties of modern man-made leathers on base cloth

The article presents research on deformational properties of modern man-made leathers on the base cloth that are used for the shoe upper molding. The analysis of curves of dependence of load on the relative prolongation of materials under uniaxial tension is carried out. The parameters of breach work are obtained as well as ratios of tension and indices of a power function which describes the process of uniaxial deformation of man-made leathers.
