NOVELTY - Preparing high-strength antibacterial nonwoven fabric involves carrying out partial ring oxidation treatment to the bamboo fiber to obtain portion of the epoxidized bamboo fiber, taking graphene oxide and lutetium nitrate as raw material to prepare graphene-lutetium oxide nano powder, and using N- beta - (aminoethyl)- gamma -aminopropyl methyl dimethoxy silane for modifying treatment to obtain the modified nano powder, and reacting the partially epoxidized bamboo fiber with modified nano-powder to obtain the modified bamboo fiber. USE - Method for preparing high-strength antibacterial nonwoven fabric used for disposable mask, protective clothing, scrubs and manufacture of clothing, isolation clothing or medical sheet. ADVANTAGE - The method enables preparation of high-strength antibacterial nonwoven fabric with excellent mechanical property and antibacterial property.
