摘　　要：为了研究不锈钢纤维纱的结构对织物电磁屏蔽性能及力学性能的影响,采用新型Sirospun、Sirofil-spun和全聚纺,分别纺制相同线密度的涤纶/不锈钢长丝包芯纱、涤纶/不锈钢长丝包缠纱及T/S 80/20全聚混纺纱,并采用上述纱线织制了3种平纹机织物和一上三下斜纹织物。测试织物在0~1 500 MHz低频段上的电磁屏蔽效能,并对其拉伸、断裂、顶破性能进行测试,同时在测试的基础上,分析四种织物对纱线的利用率。结果表明:在低频时,织物对电磁波的屏蔽以反射为主,吸收为辅;赛络菲尔纱织物和赛络包芯纱织物屏蔽效能相当,全聚混纺纱织物屏蔽效能较差;综合织物的屏蔽效能和力学性能,赛络菲尔纱织物性能最佳。In order to study the influence of stainless steel fiber yarn structure on the electromagnetic shielding performance and mechanical properties of the fabric,polyester/stainless steel filament core-spun yarns,polyester/stainless steel filament spun yarns and T/S 80/20 blended yarns of the same yarn linear density were spun by using Sirospun,Sirofil spun and complete condensing spinning. Electromagnetic shielding effect of the fabrics under 0 ~1 500 MHz low frequency band was tested. Besides,the tensile strength,breaking and bursting properties of the fabrics were tested. At the same time,the utilization rate of the four kinds of fabrics on the yarns was analyzed based on the test. The results show that the shielding of electromagnetic wave is mainly reflection and absorption little by the fabrics at low frequency. The shielding effectiveness of the Sirofil spun yarns fabric and the Siros core-spun yarns fabric is equivalent,and the shielding effectiveness of the complete condensing spinning fabric is poor. Considering the shielding effectiveness and mechanical properties of fabrics,the Sirofil spun yarns fabric performance is the best.
