The present invention discloses a polyamide fiber masterbatch for purifying space environment and a production process thereof, belonging to the technical field of chemical fiber manufacturing. 1–3 parts of pulverized tourmaline is mixed with 15–20 parts of polyamide resin which has been subjected to cryogenic treatment, pulverization and sieving, followed by melt extrusion to obtain tourmaline masterbatch; 4–8 parts of the tourmaline masterbatch is mixed with 70–80 parts of polyamide resin, 0.3–0.6 parts of dispersant, 0.3–0.6 parts of antibacterial agent, 0.3–0.6 parts of antioxidant and 0.3–0.6 parts of light stabilizer, then fed into a twin-screw extruder for melt extrusion and pelletization to obtain the polyamide fiber masterbatch. The masterbatch contains tourmaline masterbatch with negative ion release function and long-carbon-chain antibacterial agent, and the antibacterial agent and tourmaline masterbatch are combined through chemical interaction, so that the antibacterial agent and tourmaline masterbatch are not easy to leach out. Therefore, the polyamide fiber masterbatch of the present invention has long-lasting and high-efficiency functions of negative ion release, space environment purification and antibacterial activity.
