Abstract
A modified polyacrylonitrile fiber and its preparation process and use are disclosed. An animal hair micro powder is used as a modifier for polyacrylonitrile polymer. The weight percent of a monomer composition is as follows: acrylonitrile monomer 50.0-98.8%, initiator 0.1-0.4%, animal hair micro powder 1.0-50.0%. The preparation process of the modified polyacrylonitrile fiber comprises the following steps: 1. preparing the animal hair micro powder suspension, 2. preparing spinning dope of the modified polyacrylonitrile fiber, 3. preparing the modified polyacrylonitrile fiber. The fiber is suitable for making artificial synthetic hair product such as hairpieces, and resembles well natural human hair.
