It was discovered in the beginning of the 20 th century that FSS consisting of a periodic pattern can shield electromagnetic waves of a certain frequency. FSS structures have since been used in radar and stealth applications. The periodic pattern may be composed of a metal patch or a metal substrate with holes, and the size of the periodic pattern determines the size of the intrinsic resonance, thereby causing a change in the electromagnetic shielding effectiveness. Conventional FSS fabrication methods include metal deposition, coating, embedding conductive sheets, and photolithography. For example, CN 1236839a forms a layer of specific conductive metal film on the surface of polyester fabric by electroless copper and nickel plating, thereby giving the fabric electromagnetic shielding performance; chinese patent CN 101532248A forms a layer of copper on the surface of the polyester fabric by using a chemical copper plating method, thereby endowing the fabric with electromagnetic shielding performance; chinese patent CN 101613931A forms a continuous silver layer on the surface of the polyester fabric by using a chemical silvering method, so that the fabric has electromagnetic shielding performance. Most configurations thus result in FSS structures that are non-soft or non-flexible and therefore uncomfortable and not comfortable to wear. Can constitute the part through cutting flower tissue and be that conductive yarn all the other is ordinary yarn, and then form the frequency selection fabric, cut flower fabric simultaneously and be a woven fabric, when reaching selective electromagnetic shield, still have wearable and produce efficient characteristics. At present, electromagnetic interference (EMI) generated by electronic products can cause electrical interference to the operation of equipment and can also affect the health of human bodies. Modern people are also concerned more and more about the aspect of preventing electromagnetic radiation. Therefore, the conductive yarns are interwoven with the common yarns by using the clipping and weaving technology, and when electromagnetic radiation under a certain wave band irradiates the surface of a fabric, the conductive yarns form a periodic structure to form a resonance phenomenon, so that the effect of preventing the electromagnetic radiation is achieved.
At present, visual or visible camouflage is mostly realized by adopting composite forms such as lamination, coating, electroplating and the like, the process flow is relatively complex, the comprehensive performance of the fabric is influenced (the durability, single function and cost are worried), the visual camouflage is partially considered, the infrared camouflage is not involved, and the capability of blending and fusing with background infrared is greatly reduced.
