  • Patent number: 9567406
    Abstract: A method for obtaining an elongate polysaccharide element, in particular a chitosan thread, includes extruding a hydroalcoholic extrusible solution containing a polyalcohol of said polysaccharide through an extrusion die, coagulating the extruded solution by neutralization, and at least one operation of removing the polyalcohol. The ratio of water to polyalcohol in the extrusible solution is determined such as to obtain in the elongate element a polysaccharide with the crystalline structure thereof mainly in the form of an anhydrous allomorph. Since the polysaccharide used to prepare the extrusible solution has a weight-average molar mass Mw0, the polysaccharide in the elongate element obtained preferably has a weight-average molar mass Mw1 comprised between Mw0 and 0.7 Mw0. Since the purpose is to obtain a chitosan thread, the latter has properties of mechanical strength and flexibility that allow the thread to be tied into overhand knots and to be woven without breaking.

  • Patent number: 9238880
    Abstract: The invention relates to a method for producing an elongate polysaccharide element, in particular a chitosan thread, comprising an operation of extruding an extrusible solution of said polysaccharide through an extrusion die and an operation of coagulating the extruded solution. The extrusible solution is a hydroalcoholic solution containing an alcohol that does not form an azeotrope with water and which has a boiling point of more than 150° C. at atmospheric pressure. The coagulation operation includes a step of evaporating the water, preferably over the alcohol, producing a gelled extruded elongate element in the form of a mainly alcoholic gel, in particular by subjecting the extruded solution to a hot air flow. At least one operation of eliminating the alcohol contained in said gel makes it possible to obtain the elongate polysaccharide element.
