The invention belongs to the technical field of energy recycle, particularly relates to a full-heat-exchange heat recycle membrane and a manufacturing process thereof, overcomes the defects such as high cost, low heat exchange efficiency and poor strength in prior heat recycle membranes, and develops a full-heat-exchange heat recycle membrane using novel materials and a novel technology, this membrane being high in heat recycle efficiency, good in strength, flame-retardant and capable of degrading molds. The full-heat-exchange heat recycle membrane comprises a cellulose matrix and an absorbent layer; the absorbent layer is positioned on the cellulose matrix and is made by mixing the following materials according to a ratio of 1:5-100: a water molecular absorbent and a solvent. The membrane of the invention is obtained by applying the absorbent layer to the cellulose matrix and drying; the membrane is high heat recycle efficiency, good in strength, flame-retardant and antibacterial ad is suitable for popularization and application.
