Therefore, with the development of technology and the demand of people, various antibacterial underclothes appear on the market, and the product can effectively inhibit the reproduction of bacteria and prevent peculiar smell and infection caused by the bacteria.
The antibacterial underwear is made of antibacterial fabric. The existing antibacterial fabric product can completely kill staphylococcus aureus, escherichia coli, gonococcus, streptococcus, candida albicans, pseudomonas aeruginosa and other bacteria, fungi and mould. However, since the frequency of changing and washing the underwear is high, there is a risk that the antibacterial effect is reduced after many times of high-intensity washing.

Antibacterial test method
The bacteriostatic effects of examples 1-3 and commercially available antibacterial fabrics (comparative example 1: Antarctic N6N5T85202N pure cotton maternity underpants and comparative example 2: ancient and modern EXJSJ65-2 Men's antibacterial crotch cotton boxer) on Staphylococcus aureus, Gardner vaginalis, Neisseria gonorrhoeae and Candida albicans were tested using AATCC100-2004 standard as shown in Table 1. Washing fastness of antibacterial finishing: washing with standard synthetic detergent 4g/L at 80 deg.C for 30min at bath ratio of 1: 50; the fabric was taken out, washed with cold water, and dried in the air for 1 wash. The above method was repeated n times to test the antibacterial properties of the washed fabrics.
TABLE 1 bacteriostatic Properties of the samples
As can be seen from the data in Table 1, the cotton fabric finished by the method has good bacteriostatic performance on staphylococcus aureus, gardnerella vaginalis, neisseria gonorrhoeae and candida albicans compared with the comparative sample. However, in the finishing method, the tung oil and the TPU are mixed to form a coating, and the physical structure of the TPU is strengthened through the tung oil oxidation crosslinking catalyzed by the photocatalyst initiated by ultraviolet light, so that a cross polymer film is formed, and the washing fastness of the antibacterial performance is improved. After 10 times and 20 times of high-intensity washing, the bacteriostasis rate of various pathogenic bacteria can still be maintained to be more than 90 percent. And the comparative sample is washed with high strength, so that the bacteriostatic rate effect is greatly weakened.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention. All the components not specified in the present embodiment can be realized by the prior art.
