THE USE OF THE NONLINEAR THEORY OF VISCOELASTICITY FOR DESCRIBING THE RHEOLOGICAL PROPERTIES OF TEXTILE THREADS AND MATERIALS

This work provides the mechanical properties of textile materials, describing their properties. It is presented data on the rheological models used for the description of process of dissipation of energy in material at var- ious dynamic influences. The possibility of use of the hereditary theory of viscoelasticity of Boltzmann - Voltaire with A.R. Rzhanitsyn's kernel for the description of rheological properties of threads is proved. Parameters of a ker nel of a relaxation of various threads and fabric are determined by M.A. Koltunov's technique from experimental curves of creep.
