1. A flame retardant and antistatic regenerated polyester wig fiber, which is made of following components in parts by weight: 40-50 parts of regenerated polyester, 20-30 parts of modified flame retardant regenerated polyester masterbatch, 15-25 parts of modified antistatic regenerated polyester masterbatch, 1-2 parts of colorant, 3-5 parts of additive, 1.5-3 parts of dispersant, and 1-1.5 parts of plasticizer, wherein
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 the modified flame retardant regenerated polyester masterbatch and the modified antistatic regenerated polyester masterbatch;
the modified flame retardant regenerated polyester masterbatch includes the composite flame retardant composed of PSPPP, DOPO-FT, and DOPO-TPN with a mass ratio of (2-4):(0.5-2):(3-5); and
the modified antistatic regenerated polyester masterbatch includes the biomass-derived graphene.
