The present invention discloses a preparation method of a cotton bast fiber and chitosan composite non-woven fabric for filtration and belongs to the technical field of fiber materials. The preparation method adopts steam flash explosion for pretreatment to separate cotton bast first, then a papermaking method is used for forming, finally chitosan is added to enhance the mechanical performance and improve the filtration efficiency, and a technological process is simple, environmentally friendly and suitable for industrial production. The non-woven fabric adopts lignin-rich cotton bast fibers and chitosan as raw materials, so that the non-woven fabric has good antibacterial performance. The cotton bast and chitosan used in the preparation method are both bio-based materials which can be degraded in the natural environment after use, so that burdens caused to the environment are reduced. At the same time, the problem that electrospinning methods are difficult to use in industrialized and mass production is avoided.
