| Outline of Final Research Achievements |
We investigated the regenerated fibers of keratin protein and the addition of functional pigments to the regenerated fibers using wool or human white hair by electrospinning. First, we examined the extraction of keratin protein from wool and white hair using a solution of guanidinium chloride and tris(3-hydroxypropyl)phosphine. Then, we investigated the appropriate conditions of the keratin solution concentration, applied voltage and the distance between the nozzle and plate electrodes for making regenerated keratin fibers by electrospinning. We also succeeded in producing regenerated keratin fibers containing Prussian blue of functional pigment and methylene blue of basic dye. We analyzed the regenerated keratin fibers by electron microscopy and confirmed the addition of the pigment and single fibers 0.2 to 0.4 μm in diameter. These results give insights into the basic knowledge on the regenerated fiber of the keratin protein and the addition of the colorant.
