Terylene is the trade name for polyethylene terephthalate, a polyester made from ethylene and terephthalic acid. Terylene was first produced by J R Whinfield and J T Dickson in the laboratory of the Calico Printers' Asociation Ltd, and patented on 29th July 1941. ICI bought the world manufacturing rights in 1947 and full-scale commercial production of Terylene began in January 1955. The material was found to be stronger than cotton, with better resistance to moisture, and therefore became a popular fibre for use in manufacturing shirts. Produced at the Shirley Institute, Manchester.
