采用因子分析法的服用织物电磁屏蔽性能影响因素分析

为探究服用织物电磁屏蔽性能的主要影响因素和影响规律,以常见服用织物作为研究对象,根据电磁屏蔽理论,分析服用织物的电磁屏蔽机制,得出织物基本参数、织物组织和纤维种类是重要影响因素。采用因子分析法对织物基本参数影响规律进行分析,提取出厚度因子和紧度因子2个主因子。研究结果表明:服用织物电磁屏蔽性能随厚度因子增大而提升,随紧度因子增大先提高后下降。在此基础上分析了织物组织和纤维种类对其电磁屏蔽性能的影响规律,结果表明相同条件下,斜纹织物屏蔽性能优于平纹织物;棉织物屏蔽性能最好,锦纶织物其次,涤纶织物最弱。

Analysis of influencing factors of clothing fabric on electromagnetic shielding performance based on factor analysis

To explore the main influencing factors and the influence rules of clothing fabric on electromagnetic shielding performance, common clothing fabrics are taken as research objects. Based on electromagnetic shielding theory, the electromagnetic shielding mechanism of clothing fabric is analyzed. The results show that the basic parameters of fabric, fabric weave and fiber species are the main influencing factors. Factor analysis is used to analyze the influence rule of basic parameters of fabric. Two principle factors of thickness factor and tightness factor are extracted. The results show that the electromagnetic shielding performance of clothing fabric increases with thickness factor increasing and increases firstly then decreases with tightness factor increasing. Based on this research, the influence rules of fabric weave and fiber species are analyzed. Under the same conditions, the electromagnetic shielding performance of the twill fabric is superior to that of plain fabric, the electromagnetic shielding performance of the cotton fabric is the best, that of the nylon fabric is the next and that of the polyester fabric is the weakest.
