Twaron (a brand name of Teijin Aramid) is a para-aramid, high-performance yarn.[1] It is a heat-resistant fibre, helps in ballistic protection and cut protection.[2] Twaron was developed in the early 1970s by the Dutch company Akzo Nobel's division Enka BV, later Akzo Industrial Fibers. The research name of the para-aramid fibre was originally Fiber X, but it was soon called Arenka. Although the Dutch para-aramid fiber was developed only a little later than DuPont's Kevlar, the introduction of Twaron as a commercial product came much later than Kevlar due to financial problems at the Akzo company in the 1970s. As of 2000, Twaron had become a global material and had been integrated into the global markets.[3] Twaron has been around for over 30 years.[4]
