John Rex Whinfield
John Rex Whinfield (born February 16, 1902 in Sutton , † July 6, 1966 in Dorking (Surrey) ) was a British chemist , inventor of the synthetic textile fiber Terylene , the first polyester fiber.
After the completion of the chemistry studies at the University of Cambridge in 1922, he was employed by Charles Frederick Cross and in the laboratory of the Society for calico Calico Printers Assoc. in Accrington . He found that polyester (already discovered as a possible textile fiber by Wallace Hume Carothers but given up as insufficiently heat-resistant in favor of polyamides ) can be stabilized with a benzene ring (built in via terephthalic acid ). With his assistant Dickson he applied for a patent on July 29, 1941, but this remained secret during World War II when Whinfield worked for the Ministry of Supply. In 1947 he became an employee of Imperial Chemical Industries (ICI) and developed the synthetic fiber Terylene on the basis of his patent . In Germany it was marketed as Diolen (glossy material works). Whinfield was most recently head of the Synthetic Fibers section at ICI and retired in 1963.
