Description

technical field [0001] The invention relates to a method for manufacturing high-conductivity polyester composite short fibers, which belongs to the technology for manufacturing functional polyester fibers. Background technique [0002] Conductive fibers usually refer to fibers with a specific resistance below 107Ω·cm under standard conditions (20°C, 65% relative humidity). This type of fiber has good electrical conductivity and durability, especially at low humidity. Excellent durable conductivity, so it has great uses in industrial, civil and other fields. The antistatic mechanism of conductive fibers is to generate corona discharge between conductive fibers. When the static voltage reaches a certain value, it will generate corona discharge without spark to eliminate static electricity. Polymer materials are usually considered as insulators. At present, organic conductive fibers are mostly used to develop antistatic fabrics. Organic conductive fibers are conductive fibers ...
