1. A method for manufacturing a wound dressing, comprising:

  • forming at least one alginate fiber by a wet spinning process;

    winding the alginate fiber around a board thereby forming a plurality of first fibers on a surface of the board, wherein the first fibers extend in parallel along a first direction;

    spraying an aqueous solution containing sodium ions on the surface of the wound first alginate fibers;

    rewinding the alginate fiber around the board thereby forming a plurality of second fibers that are stacked on the first fibers, wherein the second fibers extend in parallel along a second direction that is not parallel to the first direction so that an included angle between the first direction and the second direction is in a range between about 0°

    to 180°

    ; and

    drying the first fibers and the second fibers so that the first fibers and the second fibers are respectively bound with one another.
