This paper investigates a textile material of low surface mass for its protection against electromagnetic radiation (EMR), which is suitable for composite structures of garments, and for technical and interior applications. The shielding effectiveness against EMR of fabric knitted from polyamide threads coated with silver, measured in the frequency range of 0.9 GHz to 2.4 GHz, indicated a high degree of protection. The key contribution of the paper is the evaluation of the stability of the shielding properties against EM radiation after applying apolar and polar solvents, in synergy with the cyclic process parameters of wet and dry cleaning. The results of the study confirmed the decline in the shielding effectiveness after successive cycles of material treatment with dry and wet cleaning. The effect of wet cleaning in relation to dry cleaning is more apparent, which is due to the damage of the silver coating on the polyamide threads in the knitted fabric.
本文研究了一种低表面质量的纺织材料对电磁辐射（EMR）的防护性能，该材料适用于服装的复合结构以及技术和室内应用。在0.9 GHz至2.4 GHz频率范围内测量的由涂银聚酰胺线编织而成的织物对EMR的屏蔽效能表明其具有高度防护性。本文的关键贡献在于评估了在使用非极性和极性溶剂后，与干湿清洗的循环工艺参数协同作用下，屏蔽性能对电磁辐射的稳定性。研究结果证实了经过连续的干湿清洗材料处理循环后屏蔽效能的下降。与干洗相比，湿洗的影响更为明显，这是由于针织织物中聚酰胺线上的银涂层受损所致。
