American chemist Wallace Carothers first began the road towards polyethylene terehthalate (PET) at the French chemicals company DuPont’s laboratories in 1928, alongside close colleague Julian Hill. But it wasn’t until 1941 when the plastic was fully patented by English chemists John Rex Whinfield and James Tennant Dickson, who were employees at Manchester textiles firm Calico Printers’ Association. Though it’s now more commonly used for plastic water bottles, the material was first used as fibres for clothing in textiles.
