Problems solved by technology

[0006] The technical problem mainly solved by the present invention is: for the conductive fiber prepared by compounding traditional polyaniline and artificial fiber such as polyester, in the process of product preparation, it is difficult for polyaniline to be uniformly and tightly combined with artificial fiber, resulting in that the electrical conductivity cannot be further improved, and polyaniline After aniline is acid-doped, the electrical conductivity drops significantly due to the impact of washing times, which causes the disadvantage of poor electrical conductivity and durability of the product. A preparation method for polyaniline composite long-lasting conductive polyester fiber is provided.
