Abstract: A method of manufacturing anti-bacteria polyamide fiber via high speed spinning disclosed a kind of method, which can make manufacturing anti-bacteria polyamide fiber via high-speed spinning realized, including the preparation of anti-bacteria particles and process of high-speed spinning. The preparation of anti-bacteria particles includes surface treatment of anti-bacteria agent and its process of preparation. Choose nano zeolite carrying silver ion as anti-bacteria agent, mix the anti-bacteria particles and polymer chips, after melting, produce anti-bacteria yarns via high speed spinning. The surface treatment to the anti-bacteria agent the invention can improve the spinnability of raw material and place foundation for realizing high speed spinning.
