and step S6, performing electret process treatment, namely performing the electret process treatment on the cotton fiber net subjected to water repellency and electret finishing.
The water repellent and electret finishing treatment is padding, dipping or spraying. The water repellent treatment can reduce the influence on the adhesion of cotton fibers when meeting water, so that the adsorption friction force between the cotton fibers is reduced, the adhesion and hardening of the fibers are reduced, the fibers are kept separated, the charge conduction is reduced, the charge stability is increased, and the attenuation speed is reduced.
