| Abstract: | The human hair keratin was extracted using β-mercaptoethanol as reducing agent,urea as keratin denaturant and sodium dodecyl sulfate as stabilizer for the keratin solution.The optimal processing conditions are β-mercaptoethanol mass fraction 3%,SDS mass fraction 2%,urea concentration 7 mol/L,swelling time 2 h before reduction,reaction temperature 45 ℃ and reaction time 12 h.The solubility ratio of human hair is in the range of 58%~60% with a good repetition. |
