Etymology

The word "polyester" combines the Greek prefix poly- (meaning "many") with ester, a term derived from German Essigäther ("vinegar ether"). The name reflects the polymer's chemical structure, where multiple ester units link together. Developed in the 20th century, polyester became a staple in synthetic textiles due to its durability and versatility.
