Stab/Puncture Resistance Performance of Needle Punched Nonwoven Fabrics: Effects of Filament Reinforcement and Thermal Bonding

This paper fabricated two types stab-resistant nonwoven fabric and the stab/puncture resistance of nonwoven were studied. Nylon fibers, Kevlar fibers, and two types of low-melting point fibers-low-melting point polyester (LPET) fibers and polypropylene(PP) fibers-are made into PP/nylon/Kevlar and LPET/nylon/Kevlar nonwoven fabrics. Needle punching and thermal bonding technology are used to made stab-resistant nonwoven fabric, thereby examining the influence of low-melting point fibers content (i.e. LPET or PP fibers) and bonding mode with other fibers on the stab/puncture resistance property of nonwoven fabrics. The quasi-static stab resistance and bursting properties were compared between nonwoven fabrics and nonwoven fabric of PET filament reinforced nonwovens. The test results show that PET filament reinforcement has a positive influence on the mechanical properties of composite nonwoven fabrics, especially puncture/stab resistance performance.
