Dacron
Description
[DuPont] A registered trademark for a Polyester fiber made of Polyethylene terephthalate. In 1951, Dacron®, along with Terylene in England, became the first commercially marketed polyester fiber. Dacron® is available as yarn, staple, and fiberfill. Polyester is durable, strong, and washes well. It has good resistance to bleaches, ketones, alcohols, soaps, detergents, and dry cleaning agents. Dacron® is also resistant to creasing, abrasion, heat aging, sunlight, and insect attack. It is used for clothing, curtains, belts, fire hoses, and filled products.
