Polypropylene staple fiber is a post-processed product of polypropylene. Since there is no hydrophilic group in the molecular structure of the polypropylene short fiber, the moisture regaining rate is low and the electrical conductivity is poor.

In the production process of polypropylene staple fiber, the short-fiber polypropylene fibers and the polypropylene short fibers and the drafting roller are prone to electrostatic effects, which cause problems such as filaments, broken filaments, and difficulty in winding the rolls, which causes difficulties in production. .

The method of adding an oil agent is often used in the industry to improve the electrostatic effect of polypropylene staple fibers. Specific resistance is an important indicator for measuring the electrostatic properties of polypropylene staple fibers in scientific research and actual production.
