In this study, the effect of microscopic structure on mechanical characteristics of stretch fabric was evaluated to design fabric easier and more reasonable. Stretch fabric has anisotropic and hyperelasticity because of its microstructural effect. In order to obtain the macroscopic mechanical characteristics of the fabric, uniaxial tensile test was conducted. Also, the deformation of the yarn was recorded by the microscope to reveal the effect of microscopic structure on the macroscopic mechanical characteristics. The recorded video was analyzed with motion image analysis software TEMA (Photron Ltd.). From the analysis result, microscopic strain and the angle between warp and weft yarn were obtained. Comparing microscopic strain with macroscopic strain, the microscopic behavior of stretch fabric was clarified.
