Tensile Properties of Bristle Fibers Made from α- and β-Casein

Abstract

The tensile properties of fibers made from α- and β-casein and unfractionated casein have been compared. β-Casein fiber, oriented by stretching, was considerably better than the other casein fibers, and values for its wet and dry tenacity compared favorably with corresponding values for wool. The better fiber properties of β-casein are ascribed to its molecular structure.
