Method for sericin removal

Abstract

The present disclosure provides a method for sericin removal. Since sodium borohydride has a high hydrogen storage performance, a convenient hydrogen release, and relatively-stable chemical properties, the sodium borohydride in a sodium borohydride aqueous solution reacts with water slowly to release hydrogen. A large number of accumulated hydrogen bubbles pass through silk fibers, and produce an upward pulling force to the sericin on a fiber surface along the silk fibers under the action of inertial force and surface tension, thereby achieving the sericin removal at room temperature. Moreover, the method for sericin removal has a simple process, a complete sericin removal effect, and no damage to the structure of silk fibroin fibers, and can prepare the silk fibroin fibers with high flexibility and bright color.
