Document Type and Number:
Japanese Patent JP7346551
Kind Code:
B2
Abstract:
A high-strength hyaluronate fiber, suitable for use in a surgical suture, a lifting thread, a tissue-engineering scaffold, etc., and a manufacturing method thereof are proposed. The method includes (a) controlling a water content of a hyaluronate having a weight average molecular weight of 100 - 3,000 kDa to 50 - 95 wt% to prepare a hyaluronate paste, (b) melting the hyaluronate paste having a controlled water content at a temperature ranging from room temperature to 100°C, and then extruding the hyaluronate paste through a nozzle, and (c) drying the extruded spinning fluid to form a fiber. The hyaluronate fiber has the water content of 5-25 wt%, the tensile strength of 3 to 15 kg/mm2, and a smooth surface with small cracks, so that the hyaluronate fiber can be used for a surgical suture, a lifting thread, a filler for cosmetic surgery, a tissue-engineering scaffold, etc.
