Abstract: 　　　In order to study the effect of various knitting structures on the stabbing-resistance performance, the plain, rib and cardigan stitch are knitted using aramid fibre and the parameters such as impact time, displacement and puncture depth are tested with the roller-recording fabric stab-resistant performance tester designed by Tianjin Polytechnic University. The results show that the rib fabric has better stabbing-resistance performance and the laying order of samples affects its stab-resistant performance also when testing multi-layer fabric; rib fabrics of more than two layers or other multi-layer fabrics of different structures can satisfy the requirement of the corresponding puncture-proof standard; the slope of straight line in stabbing-resistance testing curve can reflect the stabbing-resistance performance.
