First Commercial Metallic Fiber Production: 1946, Dobeckmun Company. (Metallized yarn is not produced in the United States.)
Federal Trade Commission Definition for Metallic Fiber: A manufactured fiber composed of metal, plastic-coated metal, metal-coated plastic, or a core completely covered by metal. (Complete FTC Fiber Rules here.)
Basic Principles of Metallic Fiber Production In the more common process for production, aluminum foil is coated on one or both sides with adhesive to which the desired coloring matter has been added. A sheet of transparent plastic film is applied to each side of the adhesive-coated foil. The assembly is then slit into narrow widths.
Metallic Fiber Characteristics and Uses Coated metallic filaments do not tarnish. When suitable adhesives and films are used, they are not affected by salt water, chlorinated water in swimming pools or climatic conditions. Metallic filaments are used for decorative purposes in apparel, braids, draperies, laces, military uniform decorations, ribbons, table linens, and upholstery.
