Whinfield attended Merchant Taylors" School and Gonville and Caius College, Cambridge where he read natural sciences (1921) and chemistry (1922).
He worked initially as an assistant to Charles Frederick Cross and Edward John Bevan who had done earlier work on viscose rayon in 1892. In 1924 he was employed as a research chemist by the Calico Printers" Association based in Manchester. Whinfield and his assistant James Tennant Dickson investigated other types of polymers with textile fibre potential.
Whinfield and Dickson discovered how to condense terephthalic acid and ethylene glycol to yield a new polymer which could be drawn into a fibre.
Whinfield and Dickson patented their invention in July 1941, but due to wartime secrecy restrictions it was not made public until 1946. Imperial Chemical Industries (Terylene) and DuPont (Dacron) went on to produce their own versions of the fibre.
Whinfield served as an assistant director of chemical research in the Ministry of Supply during World World War World War II In 1947 he joined Imperial Chemical Industries.
