PREPARATION METHOD OF SILK COMPOSITION FOR ELECTROSPINNING WITH IMPROVED PRODUCTION RATE

摘要

PURPOSE: A producing method of a silk composition for electrospinning is provided to add sericin in a silk spinning solution for improving the cutting intensity of a silk fiber aggregate. CONSTITUTION: A producing method of a silk composition for electrospinning for improving the electrospinning speed comprises a step of degumming sink to make the degumming Index(DI) in the formula 1: DI= (W_1-W_2)/(W_1xS_1)x100, into 0.375-0.988. The degumming Index is the degumming rate unit value per 1% of sericin contained in the silk. W_1 is the dried weight(g) of the silk before degumming, and W_2 is the sericin content of the silk before degumming.
