Abstract
The 3D geometry of woven fabric plays a critical role in a variety of applications, including composite forming, filtering behavior, and the permeability of medical textiles, protective clothing, and geotextiles. It is also crucial to consider this geometry in fabric processes such as dyeing, drying, and finishing. It is well known that the porosity geometry of a fabric significantly influences its permeability. Therefore, to model and simulate the fluid permeability of woven fabric accurately, a precise representation of fabric pores and unit cells is necessary. In this study, the pore geometry and unit cell of a woven fabric were analyzed using software simulation. The relationship between changes in fabric and yarn specifications on the 3D pore geometry of basic unit cells was systematically visualized for different yarn cross-sections, namely circle, lens, and racetrack. By comparing the results of the model with Becker's method and calculating the volume of pores and fabric in the composite samples to ensure the correctness and accuracy of the model, the impact of fabric changes and yarn characteristics on the volume of pores was investigated. Fabric volume variations are not substantial under various conditions of the unit cell. The pore volume increases linearly with increasing yarn amplitude. The shape of the cross-section influences the yarn amplitude. The airflow rate in the vertical direction decreases from unit cell type 3 to 4, 2, and 1
