This work presents a brief results comparison of two different attempts at the nonlinear characteristics of the same textile "Panama", manufactured by Sattler Company (Germany). On the basis of uniaxial tension and creep-recovery laboratory tests the rheological properties of technical fabric were identified. To describe material's nonlinear behaviour in its inelastic range constitutive relations of viscoplasticity and viscoelasticity were applied. The same procedure of the parameters identification, using the least squares method in the Levenberg-Marquardt variant, was conducted in each theory. Calculations were carried out for warp and weft threads individually, that is in two perpendicular directions of the material's weaving. Identification results were verified and compared to the experiments. Both nonlinear model representations advantageously approximate the tests' data of the examined technical fabric.
