Abstract: A method and system for producing an improved dressing product, useful for covering/protecting a moist wound is disclosed. The dressing product comprising fibers of a spinnable polymer forming a twisted ribbon. By virtue of this twisting, the fibers, in particular at the periphery of the ribbon, are connected to one another so as to afford better mechanical cohesion and a smoother outer appearance, without affecting the action of absorption, dilation and gel formation for extracting the biological fluid, nor the action of retention of proteins and other cellular and bacterial waste matter which would impede the phenomenon of cicatrization. The ribbon twisting equipment comprises a conical bowl (1) for driving fibers in rotation with a twisting die (3) in its narrowed downstream part (2), and a gear mechanism (4) for driving in rotation.

Abstract: The wound-treatment system is natural and is adapted to change state in a reversible manner by passing from the gel state to the solution state and vice-versa, and has polysaccharide macromolecules (10, 20, 30) and aliphatic chains (11-15, 21-24, 31-33) attached to a single polysaccharide macromolecule. The aliphatic chains (21-24) attached to a polysaccharide macromolecule (20) are, in the gel state, associated with aliphatic chains (11, 12/13, 31) attached to at least one other polysaccharide macromolecule (10, 30) by physical bonds.

Abstract: The dressing product comprises a metal alginate fibre core (1) surrounded by a supporting sheath (2) of a structure permeable to biological fluid and biocompatible with the wound. The core (1) and sheath (2) both extend into a continuous layer of alginate fibres and provide drainage slots (7, 8) between each other.
