Alginate-containing wound dressing, method and apparatus for making the same

摘要

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.

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.
