A method is disclosed for the production of microfibres or nanofibres based on hyaluronic acid and/or a water-soluble metal or non-metal salt thereof or a mixture of salts and/or a derivative of hyaluronic acid by the method of dry spinning and/or solution blow spinning. Two-dimensional or three-dimensional fibrous materials may be formed from said microfibres and nanofibers, for example in the form of a layer or cotton wool. A device for carrying out the method is also disclosed. The device contains an extrusion piece containing a pass-through channel having an inlet opening for feeding the spinning solution and a dispensing opening for dispensing the spinning solution. The device further contains an air nozzle, the air outlet opening of which is arranged to direct the exiting air into the area surrounding the dispensing opening of the extrusion piece parallel to the axis of the dispensing opening of the extrusion piece.
A method of production of fibers based on a polymer selected from hyaluronic acid, a water-soluble metal compound thereof, a derivative thereof, or combinations thereof by dry spinning and/or solution blow spinning, the method comprising the steps of:
