The bottom of the cylinder (502) is provided with a first suction tube (509) and a second suction tube (510). The first suction tube (509) and the first delivery tube (511) are connected to the first spraying area (503), and the second suction tube (510) and the second delivery tube (512) are connected to the second spraying area (504). One-way valves are provided on the first suction tube (509), the second suction tube (510), the first delivery tube (511), and the second delivery tube (512).

8. The antistatic pretreatment device for recycled satin polyester fibers according to claim 6, characterized in that, Two lower spray pipes (513) and two upper spray pipes (515) are provided. A connecting pipe (517) is connected between the two lower spray pipes (513) and between the two upper spray pipes (515). A water inlet (501) is provided above the box body (5).

9. The antistatic pretreatment device for recycled satin polyester fibers according to claim 1, characterized in that, A support plate (6) is also fixedly connected to the top outer wall of the base (1), and a drying box (601) is provided on the support plate (6), and the fiber filament (204) passes through the bottom of the drying box (601).

10. A method for antistatic pretreatment of recycled satin polyester fibers, comprising the antistatic pretreatment apparatus for recycled satin polyester fibers as described in any one of claims 1-9, characterized in that, Follow these steps: Step 1: Place the unwinding frame (203) containing recycled satin polyester fibers onto the unwinding shaft (202) and limit its position; place the take-up frame (302) onto the take-up shaft (301) and limit its position accordingly. Step 2: Connect the other end of the fiber filament (204) to the take-up frame (302), and simultaneously control the rotation of the take-up shaft (301) and the unwind shaft (202) to realize the conveying of the fiber filament (204); Step 3: When the fiber filament (204) moves, it will pass through the coating (405) on the auxiliary roller (404), and the antistatic agent on the coating (405) will adhere to the outer surface of the fiber filament (204); Step 4: The fiber filament (204) is located between the upper spray tube (515) and the lower spray tube (513). The antistatic agent can be sprayed onto the fiber filament (204) through the lower spray head (514) and the upper spray head (516). Step 5: The pre-treated fiber filaments (204) will be wound up on the winding frame (302).
