Metal-coated synthetic fibers are materials made by applying a thin layer of metal onto synthetic fibers, such as polyester or nylon. This process enhances the fibers' properties, making them more conductive, durable, and resistant to environmental factors. The metal coating can improve the fibers' ability to reflect heat and light, making them useful in various applications. These fibers are commonly used in textiles for smart clothing, electromagnetic shielding, and industrial applications. Their unique combination of flexibility and conductivity allows for innovative uses in electronics, safety gear, and even fashion, where they can provide both functionality and style.
