NOVELTY - Preparing composite yarn comprises coating the antistatic nano fibers spun from the antistatic spinning solution on the core filaments spun by the melt spinning method and not completely cooled, partially or fully adhering antistatic nano fibers to the core wire to form an intermediate yarn, mixing polymer raw materials and auxiliary agents into twin-screw spinning machine for spinning during melt spinning process, coating the natural antibacterial yarn or multi-component yarn natural antibacterial yarn on the intermediate yarn, adding an organic solvent to the yarn obtained after coating, and drying to form the composite yarn. USE - The composite yarn is useful for outdoor clothes. ADVANTAGE - The yarn has excellent antibacterial and antistatic function and excellent durability.
