In countries with severe gun regulations, soldiers and police officers are commonly attacked by sharp weapons. 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.

在枪支法规严格的国家，士兵和警察经常受到锋利武器的攻击。当前的个人防护设备太重，因此在本研究中，将机械强度高的Kevlar®纤维，尼龙纤维和低熔点聚酯（LMPET）纤维针刺制成薄，轻且舒适的无纺布。热粘合和热压热处理用于热粘合纤维，其随后产生致密且刚性的表面，这是因为非织造织物由于纤维的特性而受到针刺或光滑状态的破坏而导致结构受损。透气性，抗张强度和准静态防刺性能测试结果证明，致密表面与热压热处理有关。
