Abstract

The invention concerns a chitosan spinning method characterized in that it consists in subjecting the chitosan collodion to the coagulating action of a gas, preferably ammonia. The invention also concerns a device for implementing said method, which consists in placing the extrusion die output in a coagulating gas atmosphere. The invention further concerns the yarn obtained by said method and uses thereof in various types of industries.
