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.

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.
