Combined with Laplace transform and creep stress conditions, an accurate expression of the viscoelastic Poisson’s ratio calculated from the transverse strain and relax modulus is derived. From creep and relax tests data, Prony series of the transverse strain and relax modulus of nonwovens with time were obtained, and the time-varying curve of the viscoelastic Poisson’s ratio of nonwovens was simulated by 1stOpt software. The method proposed can effectively obtain the viscoelastic Poisson’s ratio of nonwovens and provide a reference value for calculating mechanical indexes involved in its subsequent production and processing.
