Preparation and Characters of Wool Keratin Aqueous Solution
Wool fiber was dissolved with compound solvent(urea, β-mercapitoethanol and sodium dodecyl sulfate(SDS)) and stable keratin aqueous solution was prepared through filtration and dialysis. Dissolution rate under different conditions was disscused. The results showed that dissolution rate increased with the increase of dissolving temperature, reduction β-mercaptoethanol and assistant agent urea concentration and the addition of SDS. SDS PAGE showed the major molecular weight of the aqueous keratin solution was about 44.3KDa.
