Abstract:

To explore the main influencing factors and the influence rules of clothing fabric on electromagnetic shielding performance, common clothing fabrics were taken as research objects. Based on electromagnetic shielding theory, the electromagnetic shielding mechanism of clothing fabric was analyzed. The results show that the basic parameters of fabric,fabric weave and fiber species are the main influencing factors. Factor analysis was used to analyze the influence rule of basic parameters of fabric. There are two principle factors extracted—thickness factor and tightness factor. 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 were analyzed. The electromagnetic shielding performance of twill fabric is batter than plain fabrics` under the same conditions. Under the same conditions, cotton fabric has the best electromagnetic shielding performance, nylon fabric is the next and the polyester fabric is the weakest.

Key words: clothing fabric, basic parameter, factor analysis, fabric wave, fiber species, electromagnetic shielding performance
