Abstract
A method is proposed for analyzing the change in the relaxation parameters of polymers during deformation by the method of repeated drawing with holding at each step until relaxation occurs. It is shown that the stress relaxation curves for polypropylene fibre can be described by two Maxwellian components with variable parameters. The characteristics of the change in the relaxation parameters of polypropylene fibre during deformation are determined.
