History

Etymology

Anglicization of Spanish Rayón.

Name chosen by the National Retail Dry Goods Association of America, probably from French rayon (“a beam of light, ray”) and so called because it is shiny; however, the Oxford English Dictionary states that it is apparently a blend of ray + cotton.

From Middle French rayon [1539], from Old French rai (whence English ray), from Latin rādius (whence English radius).
