John Rex Whinfield CBE (16 February 1901 in Sutton, Surrey, England – 6 July 1966 in Dorking, Surrey) [1] [2] was a British chemist. Together with James Tennant Dickson, Whinfield investigated polyesters and produced and patented the first polyester fibre in 1941, which they named Terylene (also known as Dacron) equal to or surpassing nylon in toughness and resilience.

In 1967, the DI & staple lines were started. In 1968, a tire yarn plant was introduced. Millhaven also invented the polyester tire in this year, which was the fusion of polyester with rubber. In 1971, the plant was bought by Chemcell & Fiber Industries. The nylon filament line was shut down. In 1972, Chemcell changed name to Celanese Canada.
E. I. DuPont de Nemours in Delaware, United States, first produced Dacron (PET fiber) in 1950 and used the trademark Mylar (boPET film) in June 1951 and received registration of it in 1952. [27] [28] It is still the best-known name used for polyester film. The current owner of the trademark is DuPont Teijin Films. [29]
DuPont has been awarded the National Medal of Technology four times: first in 1990, for its invention of "high-performance man-made polymers such as nylon, neoprene rubber, "Teflon" fluorocarbon resin, and a wide spectrum of new fibers, films, and engineering plastics"; the second in 2002 "for policy and technology leadership in the phaseout ...
The polymer is formed by free-radical polymerization in aqueous suspension. The fiber is produced by dissolving the polymer in a solvent such as N,N-dimethylformamide (DMF) or aqueous sodium thiocyanate, metering it through a multi-hole spinneret and coagulating the resultant filaments in an aqueous solution of the same solvent (wet spinning) or evaporating the solvent in a stream of heated ...
In archery, UHMWPE is widely used as a material for bowstrings because of its low creep and stretch compared to, for example, Dacron (PET). [citation needed] Besides pure UHMWPE fibers, most manufacturers use blends to further reduce the creep and stretch of the material. In these blends, the UHMWPE fibers are blended with, for example, Vectran.
Dacron is the brand name of Dupont’s Type 52 high modulus fiber made specifically for sailcloth. Allied Signal has produced a fiber called 1W70 polyester that has a 27% higher tenacity than Dacron. Other trade names include Terylene, Tetoron, Trevira and Diolen.
In 1953, Brooks Brothers manufactured wash-and-wear shirts using a blend of Dacron, polyester, and a wrinkle-free cotton that was invented by Ruth R. Benerito, which they called "Brooksweave". [citation needed]
