Metallised fibre is commonly classified based on its metallic content and the type of fibre that serves as the base. One of the most common types of metallised fibre is made by coating polyester, nylon, or polypropylene fibres with a layer of metal, usually aluminium. This method allows for the creation of fibres that are not only visually striking but also maintain the strength and durability of the underlying synthetic material. The combination of the base fibre and the metal coating gives metallised fibre a unique set of characteristics that can be tailored to a variety of uses.
