The invention discloses a method for preparing a hydrophobic and highly-breathable fiber film by a mechanical technology, and belongs to the fields of green biomass fiber materials and environmental protection materials. A cellulose raw material is sequentially subjected to enzymatic pretreatment, mechanical grinding and molding drying to finally obtain the hydrophobic and highly-breathable fiberfilm. The fiber film prepared by the method has the advantages of compact structure, excellent mechanical properties, high transparency and strong hydrophobicity, and has an average water contact angle of 106 DEG and a breathability reaching 75.77s/(in .100 cc. 1.22 KPa); no chemicals are used in the preparation process of the cellulose film, so a complicated chemical reaction process is not needed, and a complicated process and high equipment input are not needed; and the water contact angle of the obtained fiber film reaches 106 DEG C, so the fiber film has good water resistance, and can be used in high humidity env
