The conductive fibers can quickly leak and disperse the generated static electricity, effectively preventing local accumulation of static electricity. The conductive fiber also has a corona discharge capability and can discharge static electricity to the atmosphere. Corona discharge is a discharge phenomenon that occurs when the radius of curvature of the electrode surface is small, the electric field in the discharge space is not uniform, and the electric field near the surface of the electrode is relatively strong under atmospheric pressure or above atmospheric pressure. There is a luminescent corona layer near the electrode, and the electric field in the layer is strong, producing strong ionization and excitation. This corona discharge is a very weak discharge phenomenon that does not pose a danger. Therefore, in the case where the conductive fiber is not grounded, the static electricity can be removed by a corona discharge method. If the conductive fiber product is in contact with the earth, the static electricity is also leaked into the earth by the conductive method while the corona discharge is being performed, and the charged amount is smaller.
The static elimination mechanism of grounded conductive fibers. When the human body wears a fabric containing conductive fibers to contact the earth, the mechanism for eliminating static electricity is to induce charge to collect around the conductive fibers and leak into the earth while corona discharge. The specific process is that when the conductive fiber is close to the charged body, an electric field is formed between the charged body and the charged fiber, and particularly, the power line is converged at the periphery of the conductive fiber to form a local ion activated region. In the air around the conductive fibers, the corona discharge generates positive and negative ions due to the breakdown of the insulation, wherein the negative ions move toward the charged body to neutralize, and the positive ions leak to the earth through the conductive fibers.
Ungrounded conductive fibers eliminate static mechanisms. When the conductive fiber is not grounded, the static electricity is eliminated by the corona discharge method, and the step of eliminating the static electricity is:
1. The charge in the fabric (charged body) is collected to the conductive fibers, and the electric charges in the conductive fibers are opposite to those of the fabric.
2. The vicinity of the conductive fiber is induced to generate a strong electric field, so that the surrounding air is ionized by the action of the electric field, which is a so-called corona discharge process.
3. Corona discharge produces positive and negative ions, and the ions opposite to the charge property of the fabric move toward the fabric and neutralize the charge of the fabric, thereby eliminating static electricity.
