The invention relates to a nanofiber with the high adsorptive property and a production technology thereof. The nanofiber is prepared from, by mass, 5 parts of a macromolecular nanometer spinning solution and 2 parts of a polymer solution, wherein the macromolecular nanometer spinning solution is prepared from polyoxytertramethylene ether glycol, ethylene glycol dimethacrylate, gamma-aminopropyltriethoxysilane, nano-silver, nano-zinc oxide and an antistatic agent, and the polymer solution is prepared from polyanionic cellulose, isopropanol, polyvinyl alcohol and an inflame retardant; electrospinning yarn passes through a delivery mechanism and is coated with the polymer solution through a coating mechanism, and the finished nanofiber is obtained. Accordingly, the adsorptive property of the nanofiber is improved, the technological process and the production cycle are shortened, and the processing efficiency is improved.
