摘要：
In order to study the mechanical properties and parametric influence of yarn pull-out from aramid plain woven fabrics, an analytical model was proposed to provide the theoretical bases for subsequent numerical modeling. The micro-geometry of the plain woven fabric was generated through weaving process simulation using the digital element approach. On this basis, the yarn pull-out behavior of a single yarn was simulated by ABAQUS. One solid element is used through the thickness of the yarn and the yarn material properties were defined. The effect of transverse pre-loading and yarn-to-yarn friction on pull-out behavior and energy transfer mechanism were obtained. The simulation results show that the differences between the simulated peak pull-out force and the peak transverse force compared to the experimental ones are 5.96% and -8.51%, respectively. The external energy is mainly dissipated in the form of frictional energy. When the transverse pre-loading and yarn-to-yarn friction coefficient increases, the growth rate of the yarn peak pull-out force gradually decreases. The proposed model is capable of predicting the yarn pull-out performance with reasonable accuracy. © 2022, Periodical Agency of Journal of Textile Research. All right reserved.
