Abstract
After the launch of Kevlar®, a new para-aramid fiber was researched on its molecular design concept in Teijin Ltd. As a result, Technora®, which is a para-aramid copolymer, was developed. Typically Technora® yarn has tenacity of 24.5 cN/dtex, tensile modulus of 530 cN/dtex, and 2 % equilibrium moisture regain under the standard condition. The super fiber was generated from the isotropic solution unlike Kevlar®. An overview of Technora® is given with emphasis on its molecular design, process, and its physical and chemical properties, comparing to PPTA.
