Addressing the lengthy testing times, complex procedures, and high costs of current methods for evaluating fabric thermal properties, this study introduces a numerical simulation and prediction approach for determining fabric thermal conductivity and thermal effusivity. Using ANSYS/APDL finite element software, we developed a parametric model to effectively simulate and analyze temperature distribution characteristics across various woven structures, fabric densities, and materials for warp and weft yarns. The thermal conductivity and thermal effusivity of the fabrics were calculated using a unit cell structure model and validated through experimental results. Our findings demonstrate that ANSYS/APDL parametric modeling can be effectively applied to various fabrics with different woven structures, fabric tightness levels, and materials for both warp and weft yarns. The absolute error between the simulated and experimental thermal conductivity results is within 5%, and the absolute error for thermal effusivity is within 7%, indicating a strong agreement between simulation and experiment. Additionally, our results reveal that increasing fabric density leads to higher thermal conductivity and thermal effusivity.
