Mathematical Model of the Final Stage of Orientation of Polypropylene Fibre

  • Published:
Fibre Chemistry Aims and scope

Abstract

A mathematical model of the final stage of orientation of polypropylene fibre is constructed. The stress of the polymer in the hyperelastic state is used as an indirect estimation of the orientation index. A relaxation model with variable parameters is used for indirect evaluation of the change in the structure of the polymer during deformation. The curve of the parameters of the relaxation model as a function of the deformation and temperature is described by nonlinear regressive equations. The mathematical model is intended for evaluating the state of a polymer, imitation modeling, and selection of optimum orientation regimes.
