Teijin Aramid launches black Twaron fibre

Teijin Aramid has started the production of the first all black aramid fibre Twaron Black in Emmen, Netherlands. Twaron, normally golden yellow in colour due to the chemical process, now is available in black in the same quality. At the request of customers in the sailing and sports industries, the company started to investigate other colours for the fibre. Twaron Black will soon be seen for the first time in the sails of the world’s largest ocean sailing race, the Volvo Ocean Race.

According to the company, black aramid fibres have already been produced in the world, but they do not have the same characteristics (modulus) as the standard Twaron aramid fibre. For the threads to become completely black, they are not dyed afterwards, like cotton fibres. The production process has been adjusted to inject the fibre with the black dye during the process. This makes it the first black aramid fibre with characteristics that are equivalent to the standard golden yellow fibre.
With its three production sites in the Netherlands, the company says it manufactures more than half of the world’s production of aramid. The fibre is five times stronger than steel at the same weight and is often used in bullet-proof vests, ropes and cables, sails, and fire-fighter suits.
