A method of preparing an antibacterial anti-yellowing ZnO antimony-free polyester fiber is provided. In direct spinning of antimony-free polyester melt, an anti-yellowing nano antibacterial agent is introduced into a polymerization process of antimony-free polyester to obtain the antibacterial anti-yellowing ZnO antimony-free polyester fiber; the anti-yellowing nano antibacterial agent is a surface-deposited or coated nano ZnO of a phosphate ester small molecule having a function of resisting thermal oxidative degradation, the phosphate ester small molecule is bound to the nano ZnO by van der Waals force, hydrogen bonding or covalent bonding, and the phosphate ester small molecule is a phosphate ester molecule with a molecular weight of less than 500 Da; the content of the nano ZnO in the antibacterial anti-yellowing ZnO antimony-free polyester fiber is not lower than 1.2 wt %, and the yellowing index Yi value of the antibacterial anti-yellowing ZnO antimony-free polyester fiber is not higher than 16.1.
