Abstract

See full text

The present disclosure discloses a high-whiteness polyimide microfiber and a preparation method thereof and use. The polyimide fiber includes polyimide obtained from the reaction of wholly alicyclic dianhydride HTDA and an aromatic diamine monomer containing methyl or trifluoromethyl by chemical imidization. In the present disclosure, the polyimide microfiber has both excellent heat-resistant stability and spinning film-forming property, and the fabric has ultra-high whiteness. The microfiber fabric prepared from the polyimide fiber may be used as a component with high-temperature resistant and high-whiteness in personal protective equipment such as mask and protective clothing, and also may be used as an electronic component in the high-tech field such as aerospace, optoelectronic, microelectronic and automobile.
