第51卷第8期2023年8月CottonTextileTechnology包覆纱织物的制备及防刺性能研究金礼月1钟林1曹海建1孙茂军2黄晓梅1(1.南通大学,江苏南通,226019;2.南通腾龙复合材料有限公司,江苏南通,226019)摘要:研究捻度、纬密对包覆纱织物切割性能的影响规律,并探究包覆纱织物混杂结构的动态防刺性能。分别以芳纶1414长丝、超高分子量聚乙烯(UHMWPE)长丝为原料,制备芳纶1414/UHMWPE(K/P)、芳纶1414/芳纶1414(K/K)包覆纱平纹和三维深角联织物,重点研究了捻度、纬密对包覆纱织物静态切割性能,以及混杂结构对包覆纱织物动态防刺性能的影响规律。结果表明:纤维体积相同的条件下,同一外包捻度的K/K包覆纱织物的静态切割性能优于K/P包覆纱;包覆纱平纹织物的静态切割力都随着纬密的增加而增加;K/P包覆纱织物的防刺性能均优于K/K包覆纱;混杂结构中,三维深角联织物的质量分数为50%左右时,防刺性能较优。关键词:芳纶1414长丝;超高分子量聚乙烯长丝;包覆纱;静态切割;动态穿刺;混杂结构中图分类号:TS101.92文献标志码:A文章编号:1000-7415(2023)08-0049-06Preparationandanti-stabbingpropertystudyofwrappedyarnfabricJINLiyue1ZHONGLin1CAOHaijian1SUNMaojun2HUANGXiaomei1(1.NantongUniversity,Nantong,226019,China;2.NantongTenglongCompositeMaterialCo.,Ltd.,Nantong,226019,China)AbstractTheinfluencelawoftwistandweftdensityoncuttingpropertyofthewrappedyarnfabricwasstudied,andthedynamicanti-stabbingpropertyofthewrappedyarnfabricwithhybridstructurewasexplored.Aramid1414filamentandultrahighmolecularweightpolyethylenefilament(UHMWPE)weretakenasrawmaterials.Aramid1414/UHMWPE(K/P),aramid1414/aramid1414(K/K)wrappedyarnplainweavefabricsandthree-dimensionaldeepanglejointfabricswereprepared.Theeffectoftwistandweftdensityonstaticcuttingpropertyofwrappedyarnfabric,theeffectlawofhybridstructureonthedynamicanti-stabbingpropertyofwrappedyarnfabricwerediscussedemphatically.Theresultsshowedthatundertheconditionofthesamefibervolume,thestaticcuttingpropertyofK/KwrappedyarnfabricwiththesametwistwasbetterthanK/Pwrappedyarn.Thestaticcuttingforceofwrappedyarnplainfabricwasincreasedwiththeincreaseofweftdensity.Theanti-stabbingpropertyofK/Pwrappedya...
