Abstract: The present disclosure provides a flame retardant and antistatic regenerated polyester wig fiber and a preparation method thereof, and relates to the field of simulated wig technology. A composite flame retardant composed of poly(sulfonyldiphenylene phenylphosphonate) (PSPPP), a derivative of 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide (DOPO-FT), and 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide triphosphonitrile (DOPO-TPN), and biomass-derived graphene are subjected to a re-polymerization reaction with an alcoholysis product BHET of a waste PET bottle flake, respectively to obtain an in-situ modified flame retardant regenerated masterbatch and an antistatic regenerated polyester masterbatch. The masterbatches are blended and melt-spun with regenerated polyester, so that the obtained wig fiber has good flame retardant property, better flame retardant coefficient and antistatic property, and a significant antibacterial effect, thereby increasing the safety of the wig.
