摘　　要：为开发低成本的柔性可穿戴防刺材料,选用线密度为48.2tex的高性能芳纶1414短纤纱线和直径为0.06 mm的304不锈钢长丝,采用包芯纱工艺纺制芳纶/不锈钢长丝包芯、纱,优化纺纱工艺参数,得出最佳纱线包绕数,并用该纱线制备出具有防刺性能的织物。对纱线的力学性能和织物防刺性能进行测试,改变织物叠层数,探讨叠层数对织物防刺性能的影响。研究结果表明:当纱线的包缠捻度为200捻/m左右时,纱线的断裂强度为77.99 c N/tex,有害毛羽指数为90.42,可满足后续织物的织造;平纹织物的刀刺和锥刺性能与织物叠层数呈正相关线性关系。锥刺和刀刺的刺入原理不同,锥刺的破环机制是纱线滑移,刀刺的破坏机制是纱线切割断裂。To investigate flexible,wearable and low-cost stab-resistant materials,high-performance1414-aramid fiber（ 48. 2 tex） and 0. 06 mm 304 stainless-steel wires were employed to produce stabresistant fabric by adopting core-spun yarn preparation process,and optimizing the spinning process parameters to obtain optimum yarn twisting number. The mechanical properties of yarns and the stab resistance of fabrics were tested. And the influence of number of laminated layers on stab-resistance performance was investigated by changing the number of laminated layers. The results show that when yarn is wrapped at 200 twists/m,its fracture strength is 77. 99 c N/tex,and harmful hairiness index is90. 42,which are suitable for subsequent weaving of fabrics. The knife-stab and spike-stab performance of plain fabrics has positive correlation linear relationship with the laminated layer number of the fabrics.The damage mechanisms between knife-stab and spike-stab are different; and spike stab is caused by yarns slip,and knife-stab results from yarn cutting and fracture.
