[0100] A method for preparing a fluorescent flame-retardant fabric includes the following steps:
[0101] (a) Preparation of fluorescent flame-retardant polyester fiber
[0102] Manufacture of fluorescent polyester skin layer material: After uniformly mixing 1,4-bis(2-cyanostyryl)benzene and dried part of polyethylene terephthalate, the mixture is extruded by a twin-screw machine at a temperature of 255°C. And granulation to obtain a fluorescent polyester skin material, the mass content of 1,4-bis(2-cyanostyryl)benzene in the fluorescent polyester skin material is 0.02%;
[0103] Manufacture the flame-retardant polyester core layer material: After the polyethylene terephthalate and polyphenyl phosphate bisphenol sulfone ester are uniformly mixed, they are extruded by a twin-screw machine at a temperature of 255° C. Flame-retardant polyester core material, the mass content of polyphenyl phosphate bisphenol sulfone ester in the flame-retardant polyester core material is 8%;
