Further, to verify the advancement of the examples of the present application, the following performance tests were performed for each example and comparative example:
antibacterial test: the method in GB/T21866-2008 antibacterial paint (paint film) antibacterial assay and antibacterial effect is adopted; the antibacterial test results are shown in table 1 below:
TABLE 1
As can be seen from the test results in Table 1, the easily identifiable sterilized wet tissues prepared in examples 1 to 8 of the present application produced an excellent antibacterial effect against E.coli and Staphylococcus aureus as compared with the conventional sterilized products in comparative examples 1 to 4; wherein, the antibacterial rate of the film layers of the examples 2-4 and the examples 6-8 reaches more than 99 percent; comparative examples 1 to 4 found that the antibacterial film layer increased in antibacterial rate with the increase of the content of the silver nanowire antibacterial agent, and the optimal antibacterial effect was achieved at the content of the silver nanowire antibacterial agent of 5 parts, whereas the antibacterial effect remained almost unchanged with the increase of the content of the silver nanowire antibacterial agent. Comparative examples 5 to 8 show that the antibacterial rate of the antibacterial film layer increases with an increase in the content of chlorhexidine acetate, and that the optimal antibacterial effect is achieved at a content of chlorhexidine acetate of 1 part, and then the antibacterial effect remains almost unchanged with an increase in the content of chlorhexidine acetate. As can be seen from comparative examples 2 and 6, the antibacterial film layers have extremely high antibacterial effect, and the antibacterial rate reaches 99.99%; in example 6, chlorhexidine acetate is added, and compared with example 2, the content of the nano silver wire antibacterial agent added in example 6 is less, but the antibacterial effect is almost consistent, which means that the nano silver wire antibacterial agent with higher content in the film layer, or the nano silver wire antibacterial agent and the chlorhexidine acetate are simultaneously contained, and the antibacterial effect of the film layer can be obviously improved through the synergistic effect of the two antibacterial components.
Antiviral test: ISO 21702 was used: 2019; the antiviral test results are shown in table 2 below:
TABLE 2
As can be seen from the test results in Table 2, the easily identifiable sterilized wet tissues prepared in examples 1 to 8 of the present application produced an antibacterial film layer having excellent antiviral effects against H1N1 and novel coronaviruses as compared with the conventional sterilized products in comparative examples 1 to 4; wherein, the antiviral activity rate of the film layers of the examples 2-4 and the examples 6-8 reaches more than 99 percent; comparative examples 1 to 4 found that the antiviral activity rate of the antibacterial film layer increased with the increase of the content of the silver nanowire antibacterial agent, and an optimal antiviral effect was achieved at 5 parts of the content of the silver nanowire antibacterial agent, whereas the antiviral effect remained almost unchanged with the increase of the content of the silver nanowire antibacterial agent. Comparative examples 5 to 8 show that the antiviral activity rate of the antibacterial film layer increases with an increase in the content of chlorhexidine acetate, and that the optimum antiviral effect is achieved at 1 part of the content of chlorhexidine acetate, and then the antiviral effect remains almost unchanged with an increase in the content of chlorhexidine acetate. As can be seen from comparative examples 2 and 6, the antibacterial film layer has extremely high antiviral effect, and the antiviral activity rate reaches 99.99%; compared with example 2, the example 6 has less nano silver wire antibacterial agent, but the antiviral effect is almost consistent, which means that the nano silver wire antibacterial agent with higher content in the film layer or the nano silver wire antibacterial agent and the chlorhexidine acetate are contained at the same time, and the antiviral effect of the film layer can be obviously improved through the synergistic effect of the nano silver wire antibacterial agent and the chlorhexidine acetate.
Antibacterial rapidity test: based on the method in GB/T21866-2008 antibacterial paint (paint film) antibacterial assay and antibacterial effect, the test time is changed to 15min, 30min, 1h, 6h and 24h; the results of the antibacterial rapidity test are shown in table 3 below:
TABLE 3 Table 3
As can be seen from the test results in Table 3, the easily identifiable sterilized wet tissues prepared in examples 1 to 8 of the present application have excellent antibacterial effects on E.coli and Staphylococcus aureus, and have a rapid onset of action compared with the conventional sterilized products in comparative examples 1 to 4; wherein, examples 2-4 and examples 6-8 all achieve the best antibacterial effect at 30 min; comparative examples 1 to 4 found that the time for the antibacterial film layer to reach the optimal antibacterial effect was shortened with the addition of the silver nanowire antibacterial agent, and the shortest time was reached for 30min at 5 parts of the silver nanowire antibacterial agent content, and then the time for reaching the optimal antibacterial effect was almost maintained as the silver nanowire antibacterial agent content was increased. Comparative examples 5 to 8 show that the time for achieving the optimal antibacterial effect of the antibacterial film layer is shortened with the addition of chlorhexidine acetate, and the shortest time is 30 minutes at 1 part of chlorhexidine acetate, and then the time for achieving the optimal antibacterial effect is almost unchanged with the increase of the chlorhexidine acetate content. Comparative examples 2 and 6 show that the antibacterial film layers have extremely high antibacterial effect, the antibacterial rate reaches 99.99%, and the optimal antibacterial effect is achieved in 30 min; in example 6, chlorhexidine acetate is added, and compared with example 2, the content of the nano silver wire antibacterial agent added in example 6 is less, but the antibacterial effect and the acting time are almost consistent, which indicates that the nano silver wire antibacterial agent with higher content in the film layer, or the nano silver wire antibacterial agent and the chlorhexidine acetate are simultaneously contained, and the antibacterial effect and the acting time of the film layer can be obviously improved through the synergistic effect of the nano silver wire antibacterial agent and the chlorhexidine acetate.
Antiviral rapidity test: based on ISO 21702:2019, changing the test time to 15min, 30min, 1h, 6h and 24h; the results of the antiviral rapidity test are shown in table 4 below:

Comparative examples 5 to 8 show that the time for the antibacterial film layer to achieve the optimal antiviral effect is shortened as the content of chlorhexidine acetate is increased, and the shortest time is 30 minutes at 1 part of chlorhexidine acetate, and then the time for achieving the optimal antiviral effect is almost unchanged as the content of chlorhexidine acetate is increased. As can be seen from comparative examples 2 and 6, the antibacterial film layers have extremely high antiviral effects, the antiviral activity rates reach 99.99%, and the optimal antiviral effects are achieved in 30 min; compared with example 2, the example 6 has less nano silver wire antibacterial agent, but the antiviral effect and the acting time are almost consistent, which indicates that the nano silver wire antibacterial agent with higher content in the film layer or the nano silver wire antibacterial agent and the chlorhexidine acetate are contained simultaneously, and the antiviral effect and the acting time of the film layer can be obviously improved through the synergistic effect of the nano silver wire antibacterial agent and the chlorhexidine acetate.
