China's largest single-line capacity large-tow carbon fiber production line was put into operation on Friday in Ordos City, north China's Inner Mongolia Autonomous Region, according to China Petrochemical Corporation (Sinopec).

With a designed single-line capacity exceeding 3,000 tonnes, the products are said to reach internationally advanced performance levels, marking another key step toward high-end carbon fiber development in China.

Carbon fiber offers outstanding mechanical performance and is widely used in sectors such as aerospace, new-energy vehicles and high-end equipment. Fibers with more than 48,000 filaments per tow are classified as large-tow carbon fiber, which can achieve higher single-line output and lower production costs.
