Antistatic conductive fiber and preparation method thereof

The invention relates to the technical field of textile materials, and discloses an antistatic conductive fiber and a preparation method thereof. The preparation method comprises the following steps: (1) carrying out plasma treatment on polyester fibers to obtain surface-modified polyester fibers; (2) putting the surface-modified polyester fibers into a doped solution of aniline and 5-sulfosalicylic acid-hydrochloric acid mixed acid, mixing with an ammonium persulfate hydrochloric acid aqueous solution, and reacting to obtain doped polyester fibers; (3) the doped polyester fibers are placed in ammonia water to be subjected to dipping treatment, and counter-doped polyester fibers are obtained; and (4) repeating the treatment in the step (2) on the counter-doped polyester fiber to obtain the antistatic conductive fiber. The process is simple, an antistatic synergist does not need to be additionally added, and the prepared antistatic conductive fiber is excellent and stable in performance. 本发明涉及纺织材料技术领域，公开了一种抗静电
