Long-acting antibacterial colored POY (polyester pre-oriented yarn)

The utility model discloses a long-acting antibacterial colored POY (polyester pre-oriented yarn), which comprises a first mixed twisted yarn, a second mixed twisted yarn and a third mixed twisted yarn, and the first mixed twisted yarn, the second mixed twisted yarn and the third mixed twisted yarn are mutually wound and twisted into a filament; the first mixed twisted yarn further comprises gel-state fibers, polyacrylonitrile fibers and polyester fibers, and the gel-state fibers, the polyacrylonitrile fibers and the polyester fibers are wound and twisted together. The antibacterial agent is smeared on the outer surface of the gel-state fiber. The gel-state fibers used in the silk yarn can improve the tensile property of the silk yarn, the polyacrylonitrile fibers and the polyester fibers can enable the silk yarn to be sun-resistant, acid-resistant and oxidation-resistant, and the antibacterial agent is melted in the gel-state fibers, so that the lasting antibacterial effect can be enhanced; the tencel fibers
