However Courtaulds's big advantage as manufacturer of the " Courtelle " precursor now became a weakness.
The synthetic fibre Tricell was first used in 1957 and lasted until the 1970s and another synthetic fibre called Courtelle was first launched nationally by Marks & Spencer during 1960 and also lasted well into the 1970s.
Courtelle's low cost and ready availability were potential advantages, but the water-based inorganic process used to produce it made the product susceptible to impurities that did not affect the organic process used by other carbon-fiber manufacturers.
