Abstract
The present invention relates to the production of descaled animal fiber. The scale is effectively removed by oxidation of a surface of the animal fiber with an oxidizing reagent, following by treatment with a proteolytic enzyme in the presence of salt. The resulting animal fiber has excellent shrink-proof properties.
