Advanced mesh knitted curtain fabric for electromagnetic interference shielding

In modern society, a wide variety of electronic devices, such as those linked to Wi-Fi routers and power outlets, emit significant electromagnetic radiation. This radiation poses risks not only to human and animal health but also to data security, potentially serving as a source of sensitive information leakage. While short-term exposure to low-frequency radiation typically does not result in adverse effects, prolonged exposure has been associated with various health issues, including depression, nausea, anxiety, headaches, and, in some cases, miscarriages in women. The best solution to protect human from radiation is to cover human body with electromagnetic shielded textile fabrics. Author developed five different mesh-knitted structures and compared their properties with a plain single jersey structure. The purpose of developing mesh knitted fabric is to create curtains that can block or lessen electromagnetic radiation while still allowing light and air to pass through. Composite yarn containing stainless steel wire and carbon fiber was used. Fabric construction was carried out using a fully automatic flat knitting machine. The MH3 and MH5 mesh knitted structures were newly invented. The results showed that the MH3 mesh knitted structure exhibited the highest EMI SE among all the mesh knitted fabrics. The plain single jersey fabric (PJ0) included for the comparison with mesh knitted structures and it exhibited the highest value of electromagnetic interference shielding and UPF rating.
