The invention relates to a graphene/polyvinyl alcohol modified nonwoven fabric production method, and belongs to the technical field of textile chemistry. The method comprises the following steps: dipping a nonwoven fabric in a graphene oxide/polyvinyl alcohol composite modification solution, drying the nonwoven fabric, and reducing graphene oxide to make the surface of the nonwoven fabric covered with a layer of reduced graphene oxide in order to obtain a nonwoven fabric product with excellent hydrophilic, antibiotic, antistatic and adsorptive functions. The method is suitable for modifying polypropylene fibers, terylene, polyamide, acrylic fibers, polyethylene fibers, polyvinyl chloride fibers, polytetrafluoroethylene, polyphenylene sulfide and other nonwoven fibers, and the nonwoven fabric product obtained in the invention can be used in fields of clothes, home textiles, medical health care, air purification, sewage treatment and military matters. The preparation method has the advantages of simplicity, low cost, wide application range and high application values.
