Stabbing-resistance performance of aramid fabric

The influence of knitting structure on stabbing-resistance performance of aramid fabrics were studied with aramid fibers as material. The knitting structures include plain fabrics,rib structures and cardigan. The testing on fabric stab-resistant performance was done by a self-designed and manufactured tester called ″ Roller-recording fabric stab-resistant performance tester″,and the parameters including impacting time,displacement,and depth were obtained. The results show that rib structure has better stabbing-resistance performance. For multi-layers fabric,the stacked order influence the performance of stabbing-resistance,and more than two layers of rib structures or other multi-layers structures stacked up can satisfy the requirement of the corresponding standards of stabbing-resistance. In the test of antistabbing curves,the slope of straight line can reflect the pros and cons of the stabbing-resistance performance. From this paper,we can expand the scope of the stab-resistance fabrics by combining the flexibility of knitting fabric and the stab-resistance of different aramid fabrics.
