This invention discloses a biodegradable bio-based composite wound dressing and its preparation process, relating to the field of chitosan dressing processing technology. Chitosan powder is added to purified water and stirred for 60 minutes in a constant temperature water bath to fully dissolve and form a chitosan solution. Sodium carboxymethyl cellulose is added, and stirring continues until completely dissolved. After pH adjustment, glycerin and povidone-iodine solution are added sequentially, and stirring is continued for 20 minutes to ensure the system is homogeneous and free of sediment. The mixed solution is filtered through an 80-mesh filter to remove undissolved impurities, yielding a clear dressing precursor solution. This solution is then poured into a custom mold, pre-frozen in a low-temperature freezer, and then transferred to a vacuum freeze dryer for drying. After drying, a porous sponge-like preform is obtained. The dried porous sponge preform is flattened and fed into a slitting machine for cutting. After cutting, individual dressing pieces are collected, packed into medical polyethylene composite film bags, and sealed using a packaging machine. The packaging is sealed through a processing procedure, and then sterilized and ventilated to complete the process.
