Graphene multifunctional antiviral and antibacterial soft chip and preparation method thereof

The invention belongs to the technical field of functional fiber materials, and discloses a graphene multifunctional antiviral and antibacterial soft chip and a preparation method thereof. Graphene and an inorganic functional powder material are added into silica sol for a surface gel reaction, porous silicon dioxide and a surface-modified inorganic nano powder material are obtained, then the porous silicon dioxide and the surface-modified inorganic nano powder material are added into a traditional Chinese medicine antiviral extracting solution containing calcium acetate for adsorption treatment, and multifunctional nano particles are obtained; adding the obtained multifunctional nanoparticles into a fiber spinning solution, carrying out solution spinning to obtain nascent fibers, then carrying out 160-190 DEG C steam heat treatment and vacuum drying to obtain porous fibers, carrying out weaving forming, and then carrying out soft finishing to obtain the graphene multifunctional antiviral and antibacterial so
