The invention discloses a copper modified antibacterial polyester fiber and a preparation method thereof. The polyester fiber contains 1 ~ 30wt% of copper particles, and its preparation method includes the following steps: (1) crushing metallic copper, soaking it in benzotriazole solution for 20 ~ 90 minutes, and then drying the soaked copper particles to obtain modified copper particles with surface oxidation resistance. (2) adding the modified copper particles into the high-viscosity polyester chips, and melting and granulating to obtain the copper modified polyester master batch. (3) mixing the copper modified polyester master batch with polyester chips, adding dispersant and lubricant, uniformly mixing, and vacuum drying to obtain mixed spinning raw materials. (4) melt spinning the mixed spinning raw materials at the melting temperature of 270-295 DEG C to prepare the copper modified antibacterial polyester fiber. Compared with the prior art, the invention is not only easier to popularize and apply, but also lower in production cost and simple in production process.
