Abstract:

In order to reflect the configuration and micro-geometry of yarns inside the fabric and aiming at the problem of overlooking the change of cross-section yarn shape, which was caused by relative motion between fibers, during the simulation process, this paper proposed a method for calculating the inter-fiber friction based on the digital element approach. Based on this, the micro-geometry models of five three-dimensional orthogonal woven fabrics were built at sub-yarn scale with varied cross-sectional yarn shape via weaving process simulation. Each model is composed of 4, 7, 12, 19, and 37 digital fibers per yarn respectively. The results show that when the number of digital fiber per yarn increases, the simulation time and fiber volume fraction increases, the fabric thickness, the rate of the nodal force decline, and the potential energy decreases. When the number of fiber per yarn equals to 19, the micro-geometry of the numerical model is the most consistent with the microscopic picture of the actual fabric.
