The invention relates to a dual-color cool-feeling antibacterial cotton-like PA6 filament and a preparation method thereof, comprising the following steps: S1: Uniformly blend carrier PA6 chips, colorant and dispersant, and uniformly blend carrier PA6 chips, cool-feeling antibacterial composite material and dispersant; respectively perform melt plasticization via a twin-screw extruder and water-cooled pelletizing to prepare color masterbatch for PA6 fiber and cool-feeling antibacterial masterbatch for PA6 fiber; melt-spin the obtained color masterbatch with PA6 chips to obtain colored PA6 FDY; melt-spin the cool-feeling antibacterial masterbatch with PA6 chips to obtain cool-feeling antibacterial PA6 FDY; use the colored PA6 FDY as core yarn and the cool-feeling antibacterial PA6 FDY as sheath yarn to form a dual-color cool-feeling antibacterial cotton-like PA6 filament with loops or arc structures. The PA6 filament provided by the invention can directly obtain colored PA6 fiber with high color fastness and uniform color without post-dyeing. After jet-texturing and doubling with cool-feeling antibacterial PA6 fiber, it presents a subtle dual-color effect.
