Description

technical field [0001] The invention relates to a preparation method of conductive polyester fiber, which belongs to the technical field of conductive fiber preparation. Background technique [0002] Conductive fiber is a new fiber variety that appeared in the 1960s. This type of fiber has good electrical conductivity and durability, especially in low humidity and still has good durable antistatic properties. Therefore, it is used in industrial and civil fields. Has a great use. The antistatic mechanism of conductive fibers is to generate corona discharge between conductive fibers. Corona discharge is a very gentle form of discharge. When the static voltage reaches a certain value, a sparkless corona discharge is generated to eliminate static electricity. This phenomenon is generally considered to be that the conductive fibers in the fabric, under the action of the electrostatic field, ionize the surrounding air to form positive and negative ions. One of the positive and n...
