[0002] In recent years, down products have become more and more popular among consumers for their excellent light weight and warmth. Whether in the field of clothing or home textiles, the market for down jackets, down quilts, down pillows and other products is growing, and consumers are more and more accepting of them. However, the existing raw materials for down products do not have antibacterial function, and they are prone to cause allergies during wearing and use.
[0003] Therefore, there are many anti-allergic down products on the market. They mainly add antibacterial agents to the down to make the down have certain antibacterial properties, thereby reducing allergies.
[0004] Current antibacterial down is generally made by grafting groups with antibacterial properties onto the surface of the down, or directly adding inorganic antibacterial agents to the surface of the down, etc. The former will cause the fluffiness of the down to decrease, and the antibacterial agent in the latter will easily fall off; after being washed many times, the antibacterial effect of the down will be further lost.
[0005] Therefore, it is necessary to develop a down with excellent waterproof performance, good antibacterial performance and durability. Summary of the invention
[0006] In order to solve at least one of the above technical problems and develop a down with good antibacterial and waterproof properties, the present application provides a preparation method of antibacterial and waterproof down, antibacterial and waterproof down and applications.

[0124] The main differences between the preparation methods in Examples 1 to 8 and Comparative Examples 1 to 4 are shown in Table 1. Wherein, m is the weight of the down, m1 is the weight of the first waterproof agent, c1 is the concentration of the first waterproof agent, m2 is the weight of the antibacterial agent, m3 is the weight of the second waterproof agent, and c3 is the concentration of the second waterproof agent.
[0125] Table 1
[0126]
[0127]
[0128] The down prepared in the above Examples 1 to 8 and Comparative Examples 1 to 4 was subjected to performance testing, and the testing method was based on FZ / T 80001-2002 and GB / T20944.3-2008; the test results are shown in Table 2.
[0129] Table 2
[0130]
[0131]
[0132] It can be seen from Examples 1 to 8 and Table 1 that the fluffiness of the down prepared by the technical solution of the present application does not decrease significantly after treatment, the antibacterial rate against Staphylococcus aureus can reach more than 99.5%, the antibacterial rate against Escherichia coli can reach more than 99.7%, and after washing 30 times, the antibacterial effect against Staphylococcus aureus and Escherichia coli does not decrease significantly. Therefore, the down prepared by the technical solution of the present application has excellent antibacterial and waterproof properties.
[0133] By comparing and analyzing Example 1 with Comparative Example 1, and Example 5 with Comparative Example 3, it can be seen that in the technical solution of the present application, if the down is not subjected to a second waterproofing treatment, the antibacterial effect of the down after washing will be significantly reduced. Therefore, the technical solution of the present application requires a second waterproofing treatment to improve the waterproof performance and ensure the antibacterial effect after washing.
[0134] By comparing Example 4 with Comparative Example 2, and Example 8 with Comparative Example 4, it can be seen that in the technical solution of the present application, if the down is not subjected to the first waterproof treatment, the antibacterial effect of the down will be directly affected, and the antibacterial effect on the surface of the down may be reduced because the effective ingredients of the antibacterial agent will gradually enter the internal structure of the down during the treatment and subsequent processes. However, after the down is subjected to the first waterproof treatment, the proportion of the effective ingredients of the antibacterial agent entering the interior of the down is reduced, so that the effective ingredients of the antibacterial agent can effectively form an antibacterial layer on the surface of the down, and due to the second waterproof treatment, the water washing resistance of the down is effectively improved, and the antibacterial agent is prevented from being lost to the outside, resulting in a decrease in antibacterial performance.
[0135] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
