The story
In 1941, polyethylene terephthalate was discovered in the research laboratories of the Calico Printers' Association. The new polymer was later developed into the synthetic textile fibre Terylene by ICI.
During the second World War the Calico Printer's Association produced cloth insignia for the armed forces of the UK and other Commonwealth countries like Canada. This was an economical measure to replace melton wool normally used in military insignia production.
The Calico Printers' Association acquired the assets of the United Turkey Red Company Ltd in 1960.
In 1968, the Calico Printers' Association merged with the English Sewing Cotton Company to form English Calico Ltd, which changed its name to Tootal Ltd in 1973.
