摘要： The present disclosure discloses a method for preparing a pure chitosan fiber, and relates to the technical field of preparation of chitosan. The method includes the following steps: S1, preparing an acetic acid solution; S2, preparing a chitosan stock solution; S3, treating a chitosan spinning solution; and S4, preparing a chitosan fiber. In step S3, a pretreatment machine includes a body; an driving mechanism is arranged in the body; a stirring mechanism is arranged in the driving mechanism; a scraping mechanism is arranged below the driving mechanism; a preliminary treatment mechanism is arranged at an inner upper side of the body; the driving mechanism penetrates through the preliminary treatment mechanism and is arranged in the body; a separation mechanism is arranged on a bottom of the body.
