Antistatic agent is a class of chemical additives added to various fibers or coated on the surface of various fibers to prevent the electrostatic hazard of polymer materials. The function of the antistatic agent is to reduce the resistivity of the surface layer of the polymer material with high volume resistivity to below 10Ω, thereby reducing the accumulation of static electricity during the processing and use of the polymer material.
In the textile industry, antistatic agents can be divided into fiber external use and internal use according to their application methods, external use is further divided into temporary and durable, and internal use is permanent.
The antistatic agent added during the synthesis of polymer materials or in the process of manufacturing and fiber forming is an internal antistatic agent. Internal antistatic agents are widely used in plastic products, and there are also successful examples in synthetic fibers. Synthetic fibers are made into conductive fibers instead of using surfactant-based antistatic agents but other conductive materials. The weaving of these fibers is usually done by adding some conductive substances in the fiber manufacturing process, which are obtained by the following two methods respectively.
