Abstract: Analyzes the stab feasibility of warp knitted fabric from the point of stab-resistant mechanism, meanwhile conductes the anti-puncture performance testing of warp knitted and woven fabrics and from the analysis of experimental results obtains the relationship between the structure parameters of warp knitted fabric such as the length of extension wire, fabric density, piercing piercing angle and tool face and stab performance, on this base, the anti-resistant performance of the warp knitted fabric and woven fabric have been compared, the results show that whether both on puncture force or on the utilization of the yarn and fabric strength compared to woven fabric warp knitted fabric has a distinct advantage, to provide a reference and lay the theoretical foundation for the development of the warp stab-resietant fabric.
