33 mask pieces of the masks of the examples and the comparative examples are randomly selected and are randomly divided into 11 groups, 3 mask pieces of each group are tested, the mite removing rate of the masks of the examples and the comparative examples before washing, 3 times after washing and 5 times after washing is tested according to the standard of FZ/T62012-2009 mite-proof bedding article, and the national standard GB/T20944.3-2008 part 3 of evaluation of antibacterial performance of textiles is adopted: the shaking method is used for quantitatively testing the antibacterial property of staphylococcus aureus before washing, 3 times of washing and 5 times of washing the masks of the examples and the comparative examples, and the performances of the masks of the examples and the comparative examples are shown in table 1.
Table 1: performance of the example and comparative example masks
As can be seen from table 1, in the embodiment of the medical mask made of mite-killing antibacterial non-woven fabric, as the number of times of cleaning is increased, the mite killing rate and the antibacterial rate are reduced slowly, and long-term mite killing and antibiosis can be performed, which indicates that the medical mask made of mite-killing antibacterial non-woven fabric provided by the invention has better mite killing antibacterial performance.
