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.

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

An apparatus for manufacturing a wound dressing is provided. The apparatus includes a base, a slot, a tension compensator and a take-up device. The slot has two ends and is disposed on the base. The tension compensator is slidably connected to the slot and operable to connect to at least one fiber. The take-up device includes a shaft and a board. The shaft rotates upon being driven, in which the shaft is aligned with a level between the two ends of the slot. The board is secured on the shaft for winding the fiber connected to the tension compensator.

Disclosed herein are spinning solutions and methods for manufacturing a biomaterial fiber. The spinning solution includes a biologically absorbable material having a haemostatic function, a polysaccharide selected from the group consisting of hyaluronic acid (HA) and gelatin, and a solvent, wherein the polysaccharide and the haemostatic material exist in a weight ratio between about 0.1 to about 3. The method includes steps of wet spinning the spinning solution into the biomaterial fiber.

Spinning solution and method for manufacturing biomaterial fibers

A method for preparing a dispersion of conductive carbon materials is provided. The method includes dissolving a sulfonated chitosan in an aqueous solution, wherein the amount of the sulfonated chitosan of the solution is about 0.1-3 wt %. Then, a conductive carbon material is added into the solution, and the conductive carbon material in the solution is dispersed across the solution. The conductive carbon material can be carbon black or carbon nanotube.
