How are Mixed Conductive Fiber designed to ensure that they can effectively conduct static electricity and thus prevent explosions?

Mixed Conductive Fiber are made by incorporating conductive substances such as metal ions, carbon black, graphite, metal oxides (such as TiO2, SnO2, ZnO, etc.) or other conductive particles into the fiber structure, so that the fiber itself has the ability to transmit current. These conductive substances form conductive channels inside the fiber. When the fiber is exposed to static electricity, the static charge can be quickly transferred or dissipated through these channels, thereby avoiding the accumulation of static electricity to dangerous levels.
This method uses a special spinning process to wrap the conductive substance in the fiber core or evenly disperse it in the fiber, which does not affect the original physical properties of the fiber and makes the fiber conductive. The conductive fiber produced by the skin-core composite spinning method has stable and long-lasting conductive properties.
A coating containing a conductive substance is applied to the surface of ordinary fibers to make the fiber surface conductive. However, this method may have problems such as easy detachment of the coating and uneven surface distribution, so special attention should be paid in practical applications. For some fibers, such as polyacrylonitrile fibers and cellulose fibers, after carbonization treatment, the main chain of the fibers is mainly carbon atoms, which makes the fibers conductive. The conductive properties of the conductive fibers obtained by this method are related to the degree of carbonization.
In order to ensure that the Mixed Conductive Fiber can effectively conduct static electricity, their conductive properties need to be strictly controlled. The content of the conductive substance directly affects the conductive properties of the fiber. If the content is too low, the conductive properties are insufficient; if the content is too high, it may affect the physical properties and processing costs of the fiber. The degree of dispersion of the conductive substance in the fiber will also affect its conductive properties. Even dispersion means stable conductive properties; uneven dispersion may lead to a decrease in local conductive properties. The type of polymer matrix will also affect the performance of the conductive fiber. Selecting a polymer matrix with good compatibility and processing properties will help improve the overall performance of the conductive fiber.
In practical applications, the conductive properties of the hybrid conductive fiber need to be rigorously tested and verified. This includes measuring the static decay time, resistivity and other indicators of the fiber to ensure that it meets specific anti-static requirements. At the same time, simulation tests are also required in the actual working environment to verify its explosion prevention effect.
