Electromagnetic Shielding Fabric
This product utilizes conductive yarn as its core raw material to construct an electromagnetic shielding barrier through a weaving process. Its structural composition differs fundamentally from that of traditional composite fabrics:
Conductive Yarn: Spun from a composite blend of metal fibers (such as copper, nickel, or stainless steel) and polyester fibers, this serves as the primary medium for achieving the shielding function. The metallic components form a continuous conductive network capable of efficiently reflecting and absorbing electromagnetic waves, thereby blocking the penetration of RFID signals (covering frequency bands such as 13.56 MHz) and electromagnetic radiation (EMF). This design effectively resolves the issues typically associated with pure metal fabrics-namely, their susceptibility to breakage and unstable conductivity.
Base Fibers: Incorporated alongside conventional textile materials-such as polyester fibers-these components enhance the fabric's fundamental performance characteristics. They ensure the material's flexibility, abrasion resistance, and processability, thereby preventing common defects associated with fabrics composed solely of conductive elements, such as excessive stiffness or fragility.
With a weight of 100 g/m² (±10 g), the fabric strikes an optimal balance between shielding efficacy and lightweight thinness. Produced with a standard width of 53/54 inches, the woven structure ensures a dense, tight-knit texture that resists unraveling, resulting in superior overall stability.
Key features of electromagnetic radiation shielding fabric include:
1. EMF Protection: Electromagnetic radiation shielding fabric provides effective protection against various forms of electromagnetic radiation, including radiofrequency (RF) radiation, microwave radiation, and low-frequency electromagnetic fields (EMF).
2. Conductive Materials: The fabric incorporates conductive materials such as silver, copper, nickel, or stainless steel fibers, which help to block or attenuate electromagnetic waves by creating a barrier that disrupts their transmission.
3. Shielding Effectiveness: The shielding effectiveness of the fabric is measured in decibels (dB) or as a percentage of electromagnetic radiation blocked. High-quality shielding fabrics can provide significant attenuation of EMR, reducing exposure levels to safe levels.
4. Durability: Electromagnetic radiation shielding fabric is durable and long-lasting, capable of withstanding repeated use and washing without losing its shielding properties.
5. Flexibility: Despite its shielding properties, the fabric remains flexible and lightweight, allowing for easy fabrication into clothing, curtains, blankets, and other products for personal or environmental protection.
6. Breathability: Many electromagnetic radiation shielding fabrics are designed to be breathable, allowing air to pass through while still providing effective EMF protection. This enhances comfort when used in clothing or bedding.
7. Versatility: Electromagnetic radiation shielding fabric can be used in various applications, including clothing, bedding, curtains, pouches for electronic devices, and protective enclosures for sensitive equipment.

Applications：
Personal Protection: RFID-shielding wallets, cardholders, and passport covers designed to prevent the unauthorized scanning of RFID chips embedded in bank cards and passports, thereby safeguarding personal information.
Portable Storage: Shielding pouches for electronic devices (such as mobile phones, USB drives, and hard drives) that prevent electromagnetic interference from compromising device performance or protect against the wireless theft of device data.
Specialized Applications: A limited range of applications in protective apparel (e.g., pocket linings) and office organization (e.g., document folders and device bags), tailored to suit daily or professional environments where electromagnetic shielding is required.
