The invention discloses a preparation method of an antibacterial barrier polyamide fiber, and belongs to the technical field of polyamide fiber preparation. The preparation method is used for solving the technical problems that in the prior art, a carbon dioxide sleeve is doped with polyamide fibers, macromolecular chains in polyamide are prone to breakage, aging and yellowing, the mechanical property is reduced, and nano-silver for modifying the surfaces of the fibers is prone to losing efficacy after being washed or used, and the preparation method of the antibacterial barrier polyamide fibers is used for solving the technical problems that in the prior art, the carbon dioxide sleeve is doped with the polyamide fibers. Comprising the following steps: adding caprolactam into a heating kettle, raising the temperature of the heating kettle to 80-90 DEG C, after caprolactam is dissolved, adding a modified titanium-silicon additive and purified water into the heating kettle, introducing nitrogen into the heating
