Vectran is a manufactured fiber, spun from a liquid-crystal polymer (LCP) created by Celanese Corporation and now manufactured by Kuraray. Chemically it is an aromatic polyester produced by the polycondensation of 4-hydroxybenzoic acid and 6-hydroxynaphthalene-2-carboxylic acid.
Carbon fiber mainsail, showing grey-scale hues typical of the material. Vectran is a polyester-based high performance LCP (liquid crystal polymer) produced by Ticona. It is naturally gold in color and has a modulus similar to Kevlar 29, but has less strength loss with flex.
Nike Flywire is a thread, composed of vectran or nylon, developed by Nike to minimize weight and maximize support, and used in the upper part of a sneaker. Shoes containing Flywire became available for consumer purchase in 2008. [1]
Molecular structure of Kevlar Molecular structure of the LCP Vectran [5]. Liquid crystallinity in polymers may occur either by dissolving a polymer in a solvent (lyotropic liquid-crystal polymers) or by heating a polymer above its glass or melting transition point (thermotropic liquid-crystal polymers).

Vectran, a manufactured fiber from liquid-crystal polymer, is used in producing medical devices, for example, implants and certain surgical devices. [40] Intelligent textiles can be used for disease management as well as remote monitoring.
[4] [5] As of June 2007, Kuraray was the sole worldwide producer of Vectran liquid crystal polymer (LCP) fibre. [6] The company is listed in the first section of Tokyo Stock Exchange and is a member of the Nikkei 225 [7] stock market index. Kuraray is a member of the Mizuho keiretsu.
