Regenerated keratin fiber tow and processing method thereof

The invention discloses a regenerated keratin fiber tow and a processing method thereof, and the processing method comprises the following steps: step S1, the regenerated keratin fiber tow is washed in bath foam, and the bath foam comprises a small molecule cross-linking agent; s2, drying and densifying the regenerated keratin fiber bundles washed in the step S1; s3, the dried regenerated keratin fiber tows are subjected to steam drafting; s4, the regenerated keratin fiber tows subjected to steam drafting are subjected to oiling treatment, a used oiling agent is a deionized water diluent of a compound oiling agent, and the oiling mode is an impregnation method; and S5, drying and shaping the oiled regenerated keratin fiber tows. The regenerated keratin fiber tow obtained by the treatment method has good storage stability and light-resistant stability, and has good wet treatment firmness, and the mechanical property of the fiber is not reduced along with the prolonging of the placement time. 本发明公开了一种再生角蛋白纤维丝束及
