▎ 摘　　要

NOVELTY - Preparing structural color fiber comprises mixing silicon dioxide nano-microsphere, water, polyvinyl alcohol and graphene water dispersion liquid to obtain spinning solution, performing wet spinning to the spinning solution to obtain the structural color fiber. USE - The method is useful for preparing structural color fiber. ADVANTAGE - The fiber: avoids microsphere dropping; is not easy to fade; and has long service life. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for structure color fiber comprises fiber base body and silicon dioxide nano microsphere and graphene coated in the fiber base body.
