NOVELTY - Preparing traditional Chinese medicine component anti-coronavirus and influenza virus antibacterial and degradable multifunctional fiber comprises adding inorganic functional nanoparticles to silica sol, stirring and mixing uniformly, and then adding silane coupling agent for surface gel reaction, vacuum drying and crushing at 120-200 degrees C, and obtaining porous silica and inorganic nano powder material surface-modified by silane coupling agent. The obtained porous silica and silane coupling agent surface-modified inorganic nano powder materials are added to the traditional Chinese medicine antiviral extract solution for adsorption treatment, and freeze-dried to obtain multifunctional nano particles. Multifunctional nano particles and a degradable fiber matrix are mixed and then spun to obtain a Chinese medicine compound anti-coronavirus and influenza virus antibacterial and degradable multifunctional fiber. USE - Method preparing traditional Chinese medicine compound anti-coronavirus and influenza virus antibacterial and degradable multifunctional fiber. ADVANTAGE - The method enables prepare traditional Chinese medicine compound anti-coronavirus and influenza virus antibacterial and degradable multifunctional fiber, which has certain reinforcement to fiber materials and to a certain extent improve the spinnability of the degradable fiber substrate.
