A shiny, synthetic yarn made from aluminium-coated plastic, which lends it a distinctive metallic shine. It is woven or stitched with cotton, rayon, nylon, silk or wool to make garments. The name is also used for fabric woven from the yarn, which was especially popular in the 1970s. It was originally trademarked by the American Dow Badische Company in the 1940s for its synthetic fibre yarn but eventually came to be used for any metallic or gilted fabric.
