NOVELTY - Preparing nano antibacterial stone needle fiber material comprises (1) adding zinc salt and stone needle to oleylamine in mass ratio of 1:4-6, magnetically stirring, introducing the inert gas argon into it for 20-30 minutes, gradually heating the solution to 120-150degreesC, and fully mixing solution to obtain the first liquid; (2) injecting ethanol into above-mentioned first liquid at flow rate of 1-2 ml/min, magnetically stirring for 30-60 minutes under this temperature condition, heating it to 280-300degreesC, keeping the reaction mixture at this temperature for 20-30 minutes, naturally cooling to room temperature to obtain the second liquid; and (3) dropwise adding the second liquid to liquid heptane, centrifuging and separating the precipitate, and drying obtained product in vacuum oven at 60-80degreesC, to obtain the stone needle@zinc oxide nano-sheets. USE - The fiber material is useful for cotton pad in cosmetics and daily chemicals (claimed). ADVANTAGE - The fiber material: has good antibacterial effect, antibacterial rate is greater than 98%; and is simple and easy to prepare. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for the nano antibacterial stone needle fiber material is prepared by above mentioned method.
