Teijinconex Aramid

Following the technological breakthroughs which led to the discovery of (1) the liquid crystalline behavior ofpara-oriented aramids26 and (2) a novel method for spinning anisotropic liquid crystalline polymer solutions,27 Kevlar aramid fiber was produced and commercialized by the DuPont company in 1972. Other fibers based on aromatic polyamide compositions, which were produced and commercialized by other companies, were Technora (Teijin, Japan), Teijinconex (Teijin, Japan), andTwaron (Akzo, The Netherlands). Additionally, SVM is a fiber produced in the Former Soviet Union and it was announced in 1990 that a new aramid fiber had been introduced by Hoechst, in Germany.

The basic development and the first commercial introduction of aramid materials were done by DuPont, which continues to be the largest producer. MPDI fiber products (staple, continuous filament, yarn, and floe) under the trademark Nomex are produced by DuPont in the United States and Spain. The only other major MPDI producer is Teijin, with its fiber product Teijinconex produced in Japan. The situation is very similar with the PPTA manufacturers. The first and largest manufacturer, DuPont, produces essentially all product forms except films. DuPont s PPTA fibers are known under the trademark Kevlar , p-Aramid fiber is also produced in Ireland and Japan. The other producer of PPTA is Teijin Co., which produces two basic fibers Twaron based on PPTA, and Technora based on the ODA-PPTA copolymer. A small amount of p-aramid fibers (Armos and Rusar ) are produced in Russia, both being based on SVM copolymer [6].
