Systems analysis of the viscoelasticity of polyester fibres

Abstract

A comprehensive study of the mechanical properties of polyester fibres and other polymeric materials and prediction of deformation processes are only possible with systems analysis of the viscoelasticity of polymers. In determining the mechanical characteristics of polymeric materials and predicting the deformation processes that take place in them, selection of the mathematical model plays a role of no little importance. Although the deformation processes of one group of materials are more accurately predicted with one mathematical model, another mathematical model can be better for another group of materials. The broader the set of mathematical models and corresponding methods, the more accurately the mechanical characteristics of polymers can be determined and the more accurate the prediction of deformation processes will be. Both in selecting the mathematical model and in predicting the mechanical properties of polymeric materials, computerization of the calculations, which ensures reaching a higher level of investigation of the properties of the materials, plays a role of no little importance.
