Abstract

This study aims to enhance the electromagnetic barrier performance of conductive cut-protective fabrics by incorporating stainless steel filament fiber into the fabric. This was accomplished by combining high-performance polyethylene, polyester and stainless-steel filament fibers to produce cut-protective woven samples with different areal densities. The shielding efficiency values and the correlation between input factors, such as frequency (100-1500 MHz), stainless steel (30-50 µm) and areal density (150-250 g/m²), were computed empirically using surface response curves. Several noteworthy results and a strong correlation coefficient (R² = 0.97) were observed, indicating the model's validity. Three-dimensional surface response curves were constructed to investigate how the independent factors affected the electromagnetic shielding efficacy. Furthermore, the optimal electromagnetic shielding effectiveness value of fabric made with distinct stainless-steel filament fiber diameters is apparent at varying measured frequencies. The diameter of metallic filament fibers strongly influences the fabric shielding effectiveness.
