Evaluation of low-stress mechanical properties of cut protective workwear fabric made by using filament twisted core-sheath yarn

This study evaluates the low-stress mechanical properties of cut protective fabrics made from filament twisted core-sheath yarns. Using a six-end satin weave for its tight structure and reduced interlaces, hybrid woven fabrics were produced with stainless steel/glass filament cores and high-performance polyethylene (HPPE)/polyester sheaths at varying linear densities (98, 74, 59, 49 and 39 Tex). Twelve fabric samples with a uniform areal weight of 200 g/m² were woven and tested through the Kawabata evaluation system for tensile, shear, bending, compression, surface friction and roughness properties. The results showed that fabrics with lower core material content exhibited enhanced tensile strain, linearity and compression resilience, while those with higher core content demonstrated superior tensile strength, shear, bending, compression and surface characteristics. The findings highlight that both core material proportion and yarn structure critically affect the sensory comfort and low-stress mechanical performance of cut protective fabrics.
