Processing Technique and Property Assessment of Stab-Resistant Composite Fabrics

Abstract: 70% Nylon 6 fiber and 30% low melting polyester fiber were manufactured into nonwoven fabrics, after which the nonwoven fabrics and Nylon 66 grids were needle-punched and heat-treated, forming the Nonwoven/ Nylon 66 grid composite fabrics. The optimum parameter for heat treatment was 150°C for 5 minutes, improving the mechanical property of the composite fabrics. Subsequently, with a fixed pick-up ratio of 200%, two waterborne PU resin (SE-5030 and SE-5070) with 0, 5, 10, 15, 20, and 25 wt% of cross-linking agent were used, offering the impregnation for Nonwoven/ Nylon 66 composite fabrics. After impregnation, the Nonwoven/ Nylon 66 grid composite fabrics were measured with drop tower stab testing, quasistatic stab testing and tensile strength testing. SE-5030 contributed greater tensile strength to the composite fabrics (1129.5 N in cross machine direction (CD) and of 816.4 N in machine direction(MD)); however, SE-5070 offered the composite fabrics the optimum stab-resistance strength of 69.9 N.
