When Wallace Carothers and his team discovered polyester in 1930, they were working for DuPont. They were on the verge of discovering nylon and DuPont wanted them to continue on that track so they set aside the discovery of polyester and continued on the more promising nylon research.

Then in 1939, a group of British scientists working for Imperial Chemical Industries "ICI" using the writings of Carothers continued to experiment with his findings on polyester till they developed Terylene Polyester and had it patented. At that time, ICI and DuPont had an agreement that was signed in 1929 to share information about patents and all research developments. DuPont and ICI were competitors since the late 1920's and in 1952 the agreement was dissolved. After the development of nylon DuPont purchased the U.S. rights for further development of polyester in 1945. In 1950 a pilot plant at the Seaford, Delaware facility to produce Dacron Fiber was established. This plant would produce DuPont's version of polyester. Visit here http://www.chinafiltercloth.com/

DuPont's research into polyester led to a full range of trademarked products such as fibers, films and plastics. These products are derived mainly from petroleum.

Polyester in its material form was considered a miracle fiber. You could wash it and crumble it and it did not wrinkle. The term wash and wear was born. Polyester marketers went on to claim that you could wear a piece of polyester clothing for as many as 68 days in a row and it would still look good.

Polyester was very inexpensive and very easy to produce. A large number of companies started to produce inexpensive polyester clothing and other items. Fabrics that are made from polyester thread or yarn are used in apparel and home furnishings. Those products range from shirts, pants, underwear, jackets, hats, bed sheets, blankets, upholstered furniture and computer mouse pads. Polyester fibers are used as insulating and cushioning material in pillows and comforters. They are also used for padding for upholstery.

Industrial polyester fibers, yarns and ropes are used as reinforcements for conveyor belts, safety belts, coated fabrics and plastic reinforcements with high-energy absorption.
