The current personal protective equipment is too heavy, and therefore, in this study, mechanically strong Kevlar® fibers, nylon fibers, and Low-melting-point polyester (LMPET) fibers are needle punched to make thin, light, and comfortable nonwoven fabrics. Hot-baking and hot-pressing heat treatments are used for thermal bonding fibers, which subsequently generate a dense and rigid surface because nonwoven fabrics are subjected to damaged structure by needle punch or a slippery state due to the fibers’ properties. The results of the air permeability, tensile strength, and quasi-static stab resistance testings verify that the dense surface is correlated with hot-pressing heat treatment.

equipment also demands a light weight and breathable property. Commercially available anti-puncture protective equipment is primarily composed of nonwoven fabrics or fabrics that are combined with metal ring mesh, titanium foil, or ceramic layers coated using the thermal spraying technology. Although they have energy absorption and stab resistance, they are also inevitably heavy and inconvenient to the users [12-15]. Decker et al. found that a combination of Kevlar®/nylon fabrics and STF could strengthen the puncture resistance [13]. Rodríguez-Millánavm et al. laminated two ρ-aramid fabrics in different orders, and tested the composites of
