Disclosed herein is a method for manufacturing a wound dressing. The method includes the steps of: forming a alginate fiber by a wet spinning process； winding the alginate fiber around a board to form a plurality of first fibers on a surface of the board； spraying an aqueous solution containing sodium ions on the surface of the wound first fiber； rewinding the alginate fiber around the board to form a plurality of second fibers stacked on the first fibers, in which the second fibers are not parallel with the first fibers； and drying the first fibers and the second fibers.
