(2) comparing examples 4 to 9 with examples 1 to 3The antibacterial and antiviral schoolbag prepared in the embodiment 1-3 has better capability of resisting pathogenic microorganisms and can treat staphylococcus aureus, escherichia coli, candida albicans and H1N1And H3N2The inhibition rate is 99.9%, the mildew-proof grade is 0 grade, and the effect is obvious; example 4 when preparing the antibacterial plant fiber, the addition amount of the inorganic antibacterial agent in the textile solution of the antibacterial fiber is small; example 5 when preparing the antibacterial polyester fiber, the amount of the inorganic antibacterial agent added in the textile solution of the antibacterial fiber is small, which indicates that a good antibacterial effect can be produced only when the mass percentage of the inorganic antibacterial agent in the antibacterial textile solution is 0.5-3%; the amount of nano oxide added in the after-treatment liquid in example 6 was small; in example 7, the after-finishing liquid is not added with nano-oxide, and the antibacterial effects are slightly poor, which indicates that the after-finishing liquid can affect the capability of the schoolbag against pathogenic microorganisms, and a better antibacterial effect can be generated only when the nano-oxide with antibacterial capability is added into the after-finishing liquid and the addition amount is within the range of 1-3%;
