In this paper, fiber-tourmaline was for the first time used in preparation of fiber tourmaline nano powder. The preparation process of fiber tourmaline/PVA spinning solution based on the vinyl acetate, fiber tourmaline nano powder and EDTA was described through the use of micro-polymer chemistry laboratory equipment. The utilization of micro-polymer processing equipment-electrostatic spinning machine for the first time successfully prepared the fiber tourmaline/PVA composite nanofibers. The samples were characterized and the performance of its anion was tested, after which the impact of the addition of fiber tourmaline upon the electrospun fiber was analyzed and the best quality scores of tourmaline that need were also discussed.
