This invention relates to a method for preparing modified cellulose fiber nonwoven materials for ice crystal films. A porous membrane, consisting of a cellulose fiber spunlace nonwoven fabric with a three-dimensional texture, is tightly sandwiched between a soluble metal anode and an inert cathode to construct an electrolytic cell. The electrolytic cell is immersed in an electrophoretic modification solution containing negatively charged biocompatible macromolecules. A DC voltage is applied between the two electrodes, driving the macromolecules to actively penetrate into the spunlace nonwoven fabric via an electric field. An electrochemical oxidation reaction causes the soluble metal anode to release crosslinking ions in situ. These crosslinking ions then react with the migrated macromolecules in situ, forming a gel network within the fiber network. Finally, the product is obtained after rinsing and drying. This invention makes the preparation process more efficient, achieving deep and uniform penetration and efficient in-situ fixation of the modifier in the fiber substrate. It also protects and even strengthens the original physical texture during the modification process, resulting in high-performance gel mask materials.
