NOVELTY - Preparing non-woven fabric with strong anion releasing function comprises e.g. crushing tourmaline powder, sieving by 325 mesh sieve to obtain sieved micron grade tourmaline powder, adding tourmaline powder into the graphene oxide, carrying out high speed milling, concentrating, spray-drying to obtain nano-grade tourmaline powder, mixing nano-grade tourmaline powder with isopropanol, de-ionized water, polyethylene-vinyl alcohol, modified terylene fiber, and cerium oxide to obtain static spinning solution, and adopting high pressure electrostatic spinning to obtain non-woven fabric. USE - The method is useful for preparing non-woven fabric with strong anion releasing function. ADVANTAGE - The fabric has strong anion releasing capacity up to 8000-12000 piece/cm3.
