Artificial feathers are primarily manufactured from polyester, nylon, or high-grade silk fibers. For premium applications, look for 'memory' synthetic fibers that retain their shape after compression. Key quality indicators include fiber density (Dtex), which determines the 'fluffiness,' and the tensile strength of the central quill (stem), which should be flexible yet resistant to snapping. Ensure the fibers are UV-stabilized to prevent color fading if used for window displays or outdoor events.
