And (3) detection results: the results of the tests of examples 1 to 19 and comparative examples 1 to 3 are shown in Table 4.
TABLE 4 TABLE of test results of examples 1 to 19 and comparative examples 1 to 3

As can be seen by combining example 1 and comparative examples 1-3, and by combining Table 4, the total number of colonies of comparative examples 1-3 was significantly increased relative to example 1, with the greatest increase in the total number of colonies of comparative example 1. From this, it was demonstrated that both the nano silver powder (particle size of 50nm) and benzyl benzoate had the antibacterial effect, and the antibacterial effect of the nano silver powder (particle size of 50nm) was the best.
As can be seen from examples 1 to 5 and table 4, the total number of colonies in examples 2 to 5 is slightly increased compared to example 1, which shows that the nano silver powder (particle size 50nm) and benzyl benzoate can be more stably mixed with 100kg of polyethylene terephthalate at a specific gravity of 2:5, thereby indirectly improving the antibacterial performance of the polyester-cotton fabric.
It can be seen from the combination of example 1 and examples 6-9 and table 4 that the total number of colonies in examples 6-7 is slightly increased compared to example 1, while the total number of colonies in examples 8-9 is not changed much, which shows that the nano silver powder (particle size 50nm) and benzyl benzoate can be mixed with 100kg of polyethylene terephthalate at a specific gravity of 2:5, and even if polyethylene terephthalate is added, the antibacterial performance of the polyester-cotton fabric is difficult to improve.
As can be seen from the combination of example 1, examples 10 to 11 and table 4 and fig. 1, the total number of colonies in example 10 is slightly reduced, and the total number of colonies in example 11 is significantly increased, compared to example 1, thereby showing that the particle size of the nano silver powder and the antibacterial property of the polyester-cotton fabric have a significant effect, and the smaller the particle size of the nano silver powder, the better the antibacterial property of the polyester-cotton fabric. However, when the particle size of the nano silver powder is 50nm, the antibacterial performance of the polyester cotton fabric is not greatly improved even if the particle size of the nano silver powder is reduced, and the example 1 is still the best for cost.
As can be seen by combining example 1 with examples 12-14 and Table 4, the total number of colonies of examples 12-14 was increased compared to example 1, with the maximum number of colonies of example 12. Thus, silica gel has only a loading function, salicylate has a plasticizing function in addition to the loading function, benzyl benzoate has loading, plasticizing and antibacterial functions, and benzyl benzoate has the best effect when used alone.
As can be seen by combining example 1 with examples 15-17 and by combining Table 4, the total number of colonies of examples 15-17 decreased relative to example 1, with example 15 decreasing the greatest. Therefore, after the modified polyester fiber is prepared, the antibacterial performance of the polyester-cotton fabric can be effectively improved by performing weak acid soaking operation on the modified polyester fiber.
In addition, in combination with example 1, example 15 and examples 18 to 19 and in combination with table 4, it can be seen that the total number of colonies was decreased in example 15 and examples 18 to 19, compared to example 1, wherein the decrease degree of example 15 was the largest. Therefore, when the modified polyester fiber is soaked, the antibacterial performance of the polyester-cotton fabric can be effectively improved by the soaking time of 40min and the temperature of a soaked object at 100 ℃.
The present embodiment is only for explaining the present application, and it is not limited to the present application, and those skilled in the art can make modifications of the present embodiment without inventive contribution as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present application.
