Abstract (en)
[origin: EP3369859A1] A high performance natural silk fiber and a preparation method thereof, wherein silk, raw silk, twisted silk or braided silk thread is used as the raw material, which then becomes a high performance silk fiber after being shrunk or stretched; more specifically, a silk swelling solution is prepared by mixing an inorganic salt, an acid and water according to a certain ratio, the silk fiber is then immersed in the swelling solution in order to be stretched/shrunk; and finally the high performance silk fiber is obtained following rinsing with clean water, neutralizing and drying. The preparation method is simple and effective, and has a short process. The breaking strength of the silk fiber prepared by means of this method is comparable to that of spider silk. Therefore, it is well suited for application in high-tech fields, such as artificial ligaments, ophthalmic sutures, protective clothing, etc.
