Abstract

The present invention relates to an antistatic polypropylene fiber and a preparation method thereof. The antistatic polypropylene fiber of the present invention can be prepared by the following method: first, a spinning solution is prepared; second, a gas pressure-assisted electrostatic spinning process is used to spin the fiber; finally, the fiber is subjected to an oxidation doping treatment with a camphorsulfonic acid aqueous solution containing FeCl3, and then washed and dried to obtain the antistatic polypropylene fiber. The point-to-point resistance of the antistatic polypropylene fiber prepared by the present invention reaches 8.2×10 7 ~8.6×10 7 Ω, and the charged amount reaches 0.42-0.46 μC / piece; after 20 washes, the point-to-point resistance and the charged amount do not change significantly, indicating that the polypropylene fiber prepared by the present invention has a stable antistatic function.
