polyethylene terephthalate used as a textile fabric, 1951, proprietary name coined by E.I. du Pont de Nemours & Co.; an invented word of no etymology, on the model of nylon, etc.
late 14c. as a noun, "inhabitant of Syria," from Latin Damascenum; 1540s as an adjective, "of or pertaining to Damascus; of or resembling damask fabric," from Latin Damascenus "of Damascus," from Damascus (see Damascus).
type of corded fabric having a silk warp and a weft of wool heavier than the silk, 1710, from French papeline "cloth of fine silk and worsted" (1660s), probably from Provençal papalino, fem. of papalin "of or belonging to the pope," from Medieval Latin papalis "papal" (see papal). The reference is to Avignon, papal residence during the schism 1309-1408 (and regarded as a papal town until 1791), which also was a center of silk manufacture. Influenced in English by Poperinghe, town in Flanders where the fabric was made (but from 18c. the primary source was Ireland).
