Word Origin & History

rayon 
1924, chosen by National Retail Dry Goods Association of America, probably from Fr. rayon "beam of light, ray," from rai (see ray (1)), which was also used in M.E. 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)
