Processing Technique and Property Evaluation of Stab-Resistant Composite Fabrics
In this research, the nonwoven fabrics were made of 50 % high-tenacity polyester fiber and 50 % low melting polyester fiber, after which the nonwoven fabrics were thermal-treated at 110 °C, 120 °C, 130 °C, 140 °C and 150 °C for 1 min, 2 min, 3 min, 4 min and 5 min. Next, two layers of nonwoven fabrics were laminated with a layer glass (GF) fiber plain fabric or a layer of Nylon 66 grid, forming the sandwich structure. The nonwoven/ GF composite fabrics and the nonwoven/ Nylon 66 grid composite fabrics were also reinforced by needle-punching and thermal treatment, after which the two composite fabrics were measured with tensile strength and stab-resistant strength. Meanwhile, two layers of nonwoven fabrics needle-punched served as the control group. According to the results, Nylon 66 grid and glass fibers plain fabrics were both good at strengthening, the former reinforced the tensile strength of the composite fabrics and the later heightened the stab-resistant strength of the composite fabrics.
