1924, chosen by National Retail Dry Goods Association of America, probably from French rayon “beam of light, ray,” from rai (see ray (n.1)), which also was used in Middle English as a name for a type of cloth. So called because it is shiny. A more marketable alternative than the original patented name, artificial silk (1884), or the intervening attempt, Glos, which was “killed by ridicule” [“Draper’s Record,” June 14, 1924].
