Conductive fiber is a functional fiber that eliminates static electricity through electron conduction and corona discharge, typically referring to fibers with a resistivity below 10^7 Ω·cm under standard conditions (20°C, 65% relative humidity). Conductive fibers mainly include metal conductive fibers, carbon conductive fibers, organic conductive fibers, and composite conductive fibers.

Conductive fiber is an important variety of functional fibers, which has a wide range of applications in daily life, industrial production, and national defense, mainly used for electronic signal transmission, prevention of static electricity generation, and electromagnetic wave interference.

Conductive fibers, as an important type of material, have shown great application prospects in various fields such as smart wearables, aerospace, medical, and electronic communication, and are becoming increasingly important in the materials field.

In 2022, the market size of China's conductive fiber industry was 19.98 billion yuan, of which organic conductive fibers accounted for approximately 47.1%, metal fibers for about 34.8%, carbon fibers for around 9.8%, and composite conductive fibers for about 8.4%.

Due to the wide variety of conductive fiber products and the continuous emergence of new products with ongoing research and development, there are numerous participants in China's conductive fiber industry.
