Currently, objective measurements of textile fabrics refer to mechanical and physical properties measured by testing devices such as KES (Kawabata's evaluation system) and FAST (fabric assurance by simple testing). Textile scientists and engineers can easily obtain the values of these properties, but their use for developing models of fabric behavior is rare, although this is the simplest and most correct way to do it. Here, we develop an analytical model of the tensile force dependent on strain for a fabric sample, integrating the Kawabata parameters obtained by means of this test. The empirical stress-strain curves of some fabrics are presented and compared with curves obtained analytically.
