ABSTRACT:
A novel wound dressing material is produced by a chemical treatment of animal fibers, particularly, wool, to strip off the keratin layers of the surfaces of the fibers so as to expose the non-keratin protein in the underlayers, which is hydrophilic. The wound dressing material provides healing and regenerating effects on the wounds, and can be produced at a low cost.
