1. Antistatic fabrics can be divided into two categories: civil and industrial electrostatic protective clothing. According to the end use, electrostatic protective clothing can be divided into dust-free and sterile work clothes, fire and explosion-proof work clothes, surgical clothes, safety work clothes (such as electrostatic protective clothes and conductive clothes worn by electric workers at work), etc.

2. Hydrophilizing the fiber with surfactant

The principle of action is that the hydrophobic end of the surfactant molecule is adsorbed on the surface of the fiber, and the hydrophilic polar group points to the space to form a polar surface, which absorbs water molecules in the air, reduces the surface resistivity of the fiber, and accelerates the dissipation of charges. The surfactants used include cationic, anionic and nonionic. Among them, cationic surfactants have the best antistatic effect, and high molecular weight nonionic surfactants have the best antistatic effect and durability. The advantage of this method is that it is simple and easy to implement, and it is especially suitable for eliminating electrostatic interference in the textile processing process; the disadvantage is that the antistatic effect is poor in durability, the surfactant is volatile, and it is not resistant to washing, and it does not show resistance in low humidity environments. Electrostatic performance.
