Teijin Aramid (Arnhem, The Netherlands) has started production of the first all-black aramid fiber, Twaron Black, in Emmen, The Netherlands. Twaron, normally golden yellow in color due to the chemical process, now is black for the first time. At the request of customers in the sailing and sporting goods industries, Teijin Aramid started to investigate other colors. Twaron Black will be seen for the first time in the sails of the world’s largest ocean sailing race, the Volvo Ocean Race. The aramid threads are not dyed in a secondary process, like cotton fibers. Instead, says the company, black dye is injected during the fiber production process. Reportedly, this technique makes it the first black aramid fiber with characteristics that are equivalent to the standard golden yellow fiber.
