The invention provides a preparation of an oxygen-adding antibacterial mask and a special material, which is characterized in that the method comprises the following steps: adopting cotton cloth or spunlace non-woven fabric, adding a functional raw material and an additive, post finishing textile, and dipping and binding into a material with oxygen-adding antibacterial functions. The material is clamped in the middle layer of a known mask, and the oxygen-adding antibacterial mask is obtained after processing. When in use, the mask can let people breathe more freely and increase the amount of oxygen inhalation, and can produce more than 1,000 negative ions / square centimeter to give people a sense of breathing in forest environment. The negative ion mask provides enough oxygen and has the advantages of disinfection, sterilization, bad breath removing, air cleaning and heavy metal and carcinogen absorbing. The oxygen-adding antibacterial mask is used by outdoor-acting people, hospital doctors, nurses, patients and healthy people and has the characteristics of simple process, mechanized production, low-cost material, and the like. The method can produce disposable masks and multiple-use masks.
