[0033] The preparation method of the pig hair keratin solution in the present invention is as follows: the pig hair is cleaned, impurity-removed and dried, then pulverized, and then mixed evenly with 0.5 mol / L tributyl phosphine solution, and the temperature is raised to 60-70°C , stirred and reacted for 2-3h, then dropped into NaOH solution to adjust the pH value to 7.5-8.5, and then centrifuged to remove solid impurities to obtain a pure pig hair protein solution. Select a protein with a molecular weight cut-off of 5000-10000 in a dialysis bag to make The protein content in the pig hair protein solution reaches 8-12%, and the required pig hair keratin solution is obtained. Wherein, the solute mass of the tributyl phosphine solution is 5-8% of the dry weight of pig hair after pulverization.
[0034] The preparation method of the wool keratin solution in the present invention is as follows: wash, remove impurities, and dry the wool, then pulverize it, add 0.5mol / L tributyl pho...
