The vessel where polyethylene terephthalate oligomer is stored is kept to 260 degree C, while the slurry, in which terephthalic acid and ethylene glycol are compounded is fed into the vessel for 6 hours to obtain an oligomer, then is delivered to another polymer vessel. Correspondingly, the compound of formula(1) and (2) are reacted at 80-100 degree C in the vessel, therein the additive and the catalyst are added in small amount, and is processed with the polymerization at 280 degree C to obtain a polyester polymer, and spun, drawn in such method that the polyester fiber is produced.
