Polyester textile fabrics are widely used in the fields of clothing, home textiles, industrial fabrics and the like due to excellent mechanical properties, wear resistance and wrinkle resistance. However, the insulating properties of polyester fibers make them susceptible to static charge build-up during rubbing. The static electricity not only can cause the adsorption of dust and particles to influence the beauty and cleanness of the fabrics, but also can cause adhesion between the fabrics to influence the wearing comfort. In addition, when static electricity accumulation is serious, electric shock or spark can be caused, so that potential safety hazards are brought, and textiles used in flammable and explosive environments are particularly formed. Therefore, developing effective antistatic technology has important significance for improving the usability and safety of the terylene textile fabric.
The existing antistatic technology has the advantage that the antistatic coating is coated on the surface of the polyester fiber, so that the generation of static electricity can be effectively reduced. Common coating materials include conductive polymers, carbon nanotubes, and the like. These materials are capable of forming a conductive network on the surface of the fiber, thereby achieving an antistatic function. The following technical problems exist in applying an antistatic coating:

Antistatic property retention (%) = (initial surface resistance of surface resistance after abrasion test) ×100% antistatic property retention (%) = (surface resistance of initial surface resistance after abrasion test) ×100%
The retention of antistatic properties after each abrasion test was recorded and analyzed.
Evaluation of results
Coating integrity:
And (3) completing: the coating does not wear or fall off obviously.
Slight abrasion: the surface of the coating is slightly worn, but the function is not affected.
Obvious abrasion: the surface of the coating is obviously worn, and the function is reduced.
Severe wear: the surface of the coating is severely worn or falls off, and the function is obviously reduced.
Antistatic property retention:
Excellent: the retention rate is >90%, and the antistatic performance is basically unchanged.
Good: the retention rate is between 70% and 90%, the antistatic performance is reduced, and the antistatic performance is still effective.
Generally: the retention rate is between 50% and 70%, and the antistatic performance is obviously reduced.
Poor: the retention rate is less than 50%, the antistatic performance is greatly reduced, and the antistatic performance is almost ineffective.
