▎ 摘　　要

NOVELTY - The preparation method of multifunctional cellulose fiber involves soaking cellulose fiber in 20 %mass sodium hydroxide solution and then washing using deionized water, dispersing the mixture in deionized water, adding 1-100 g/l polyamidoamine aqueous solution, 1 mol/l zinc chloride solution, 1-20 g/l graphene oxide aqueous solution, allyltrimethylammonium chloride, sodium dodecyl sulfate, zinc nitrate hexahydrate and nano-zinc oxide aqueous solution to the mixture, and drying. USE - The method is useful for preparation of multifunctional cellulose fiber, which is useful in textile industries. ADVANTAGE - The method enables preparation of multifunctional cellulose fiber with excellent antibacterial properties, UV resistance, yellowing resistance and washing resistance in safe manner. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for multifunctional cellulose fiber prepared by the method.
