Abstract
A process for producing a wound dressing was provided having steps of: spinning an aqueous stock containing natural polymeric materials into a spin formation solution to form a wet polymeric spin; immersing the wet polymeric fiber into a softening reagent to obtain a softened wet polymeric spin; immersing the softened wet polymeric spin into a volatile reagent to expelling moisture in the softened wet polymeric fiber to form a polymeric fiber; forming a non-woven fabric of the polymeric fiber; and treating the non-woven fabric of the polymeric fiber with a coating solution to form a porous coating on the polymeric fiber to obtain a wound dressing. A process for manufacturing a polymeric fiber is also provided. A wound dressing produced by the process is also provided.
