Both kevlar and twaron are within the aramid family of human-made fibers. DuPont is the producer of Kevlar while Teijin is the current manufacturer of Twaron (initially produced by Akzo). Both kevlar and twaron are five times more impregnable than steel yet very flexible. These fabrics are heat resistant, cut resistant, chemical resistant, and can handle high impacts. The common uses of Kevlar and Twaron are in protective gear, body armors, tires, and drumheads.
Twaron can be twisted or braided, which is essential for rope constructions. It is chemical resistant and cut resistant. Twaron was first commercially introduced in 1986. Akzo first developed it in the 1970s. In 1965, DuPont created by Kelvar, a high strength material which belongs to the aramid family of synthetic fibers. Upon development, it was first commercially used during the 1970s.
