| description | The invention discloses an extraction method of high-concentration keratin, which comprises the following steps: S1, waste animal hair is degreased, washed, dried and crushed into fiber powder, and the particle size of the crushed fiber powder is less than 1000 [mu] m; s2, dissolving the fiber powder obtained in the step S1 and an auxiliary agent in an ionic liquid, and dissolving in a gradient heating mode until the solution becomes a transparent and viscous spinning solution; s3, the spinning solution obtained in the step S2 is collected, the high-concentration keratin spinning solution can be obtained, and the auxiliaries are selected from one or more of cellulose nanocrystals, sodium alginate, silk fibroin and cellulose nanofibers. The spinning solution obtained by adopting the extraction method disclosed by the invention can be directly used for spinning, and the dissolution rate is high.
