摘　　要：为开发出低成本柔软且防刺性能良好的包装材料,选用芳纶、尼龙6(PA6)和聚丙烯(PP)短纤维通过层间增强方式构建由表层为PP/PA6/芳纶、中间层为PA6和底层为PP/PA6非织布组成的非织造三明治防刺叠层材料。探讨了改变表层芳纶纤维含量对三明治非织造叠层包装复合材料的拉伸性能、防刀刺和防锥刺性能的影响。结果表明:非织造包装复合材料的拉伸性能、防刀刺及防锥刺性能随表层芳纶含量的增加而呈线性增加;当芳纶含量为15%(质量分数)时,非织布基布具有最大拉伸载荷、防刀刺和防锥刺载荷,分别为209.24、83.52和126.85N。刀刺与锥刺的防刺机理不同,刀刺为纤维排挤和断裂,锥刺为纤维排挤。To investigate flexible,low-cost and well stab-resisting packaging material,the aramid fiber and nylon （PA6） and polypropylene （PP） staple fiber were employed to design nonwoven sandwich laminated anti-stabbing material which was composed of PP/PA6/aramid non-woven as surface layer, PA6 as middle layer, and PP/PA6 as bottom layer by interlayer reinforcing method.The tensile property and stab resistance of composite were investigated by changing the content of surface aramid fibers. The results showed that the tensile property and stab resistance increased linearly with the increase of surface aramid content.When the aramid content was 15%, the nonwoven fabric had the highest tensile load, knife-resistant and spike-resistant load, 209.24N, 83.52N and 126.85N respectively. The tensile and stab resistance increased linearly with the increasing of layer number, and the material achieved the best mechanical and stab protection when the layer number was three. Knife and spike resistance had different mechanism. Fiber fracture and fiber pushing were the mechanism for knife resistance and fiber pushing was for the spike resistance.
