Natural protein fiber has been widely used in the textile area due to its excellent dyeing property

high moisture regain

air permeability

and good compatibility with human skin. However

it is very important to find some new applications for those versatile natural fibers according to their special properties. These years

some materials are developed into small size such as Nanometer or micrometer particle

their specific surface area and chemical activity are greatly increased. In this paper

the study of the natural protein fiber powder will be reported including the study on the performance of the natural protein fiber powder

and its application in new fiber developing

new membrane developing

and biomaterials developing

etc.
