| description | The invention discloses a preparation method of antioxidant polyphenylene sulfide fibers, relates to the technical field of filter material production, and aims to solve the problem that the performance of a fiber product is reduced due to nonuniform distribution and agglomeration of nano particles in the conventional PPS fiber preparation method. The preparation method of the bi-component fiber is adopted, the bi-component fiber is prepared from PPS resin and polyacrylonitrile resin through a melt spinning process, the bi-component fiber is prepared from a skin layer component of polyacrylonitrile and a core layer component of PPS, and the antioxidant polyphenylene sulfide fiber is prepared through a post-treatment process. The pre-oxidized fiber is produced by utilizing performance mutation of the polyacrylonitrile of the skin layer at high temperature, namely the pre-oxidized fiber outer layer is formed, so that the core layer PPS can be effectively prevented from being oxidized, and the flame retardant pr |
