A synthetic polyester fiber used to make fabrics, clothing, and other textiles that are durable and easy to care for.
Dacron is a trademark name coined in the 1950s by DuPont for their polyester fiber; it derives from 'dihydric alcohol' and 'aromatic' (dacr- + -on). The name was created as a brand name rather than coming from traditional language roots.
Dacron revolutionized fashion because it was one of the first synthetic fabrics that didn't wrinkle easily and could be machine-washed—it literally changed how people did laundry in the 1950s-60s! The fact that it's a made-up trademark name shows how companies sometimes create entirely new words for their inventions.
