In order to study the movement mechanisms of plain weave fabric yarns, the numerical simulation of behavior of yarn pull-out and movement under various loading conditions was carried out on a typical plain-woven fabric. The effects of friction coefficients, model size, and pre-stress levels on yarn movement responses were analyzed in detail, and the coupling relation among pull-out length, pull-out fractured strength, and model parameter conditions, including friction coefficients and pre-stress levels were shown. The results indicate that positive correlations exist between peak pull-out loads and those main model parameters of plain weave fabrics, including the friction coefficients, model size, and pre-stress levels. As the pre-stress level rises from 200 MPa to 700 MPa, the peak pull-out load increases by 34.49%, and the existence of yarn crimps could lead to improvement of the pull-out loads. The pull-out fractured strength of yarns gradually increases with the growths of pre-stress levels and friction coefficients in the plain weave fabrics. Specifically, the pull-out fractured strength of yarns increases by 16.48% as the friction coefficient grow from 0.1 to 0.2. In addition, the pull-out fractured length of yarns of the plain-woven fabrics is highly dependent on the actual stress state, and the homogenization of the stress state is an important factor that influences the pull-out fractured length.
