Background
The problem of body odor always troubles many people, and the reason is that secretion of apocrine sweat glands is discharged out of the body along with sweat, and is decomposed under the action of bacteria to generate unsaturated fatty acid, so that special odor is generated, great psychological pressure is brought to patients, psychological diseases of different degrees can be caused, and depression of different degrees can be caused seriously.
There are many coats on the market today for removing body odor, but none of them completely eliminates the odor, most of them are antibacterial coats or add perfume to mask the odor, and the problem cannot be solved from the source. In order to solve the problem of body odor from the source, the sweat needs to be properly prevented from being discharged in the process of human body movement, so that the phenomenon that the released gas is not absorbed and eliminated due to excessive decomposition of the secretion of the apocrine gland by bacteria can be prevented, and the effect of completely eliminating the odor is achieved. The antiperspirant is taken as a daily product in developed countries, has no side effect after long-term use, and has no clear evidence to indicate that the use of the antiperspirant is directly related to cancer by the national cancer research institute, so that the antiperspirant has certain safety and feasibility when being applied to the surface of textiles. The textile for removing the bromhidrosis prepared from the silver fibers can promote blood circulation of a human body and provide strong antibacterial elements, and the textile can effectively reduce the formation of bromhidrosis spots after being used for a long time.

Comparative example 1
This comparative example was selected from the chinese patent (201810888082.6) which provides an elastic breathable perspiration matrix, which was knitted with an elastic breathable perspiration-deodorizing material under the armpit. Meanwhile, compared with the traditional Chinese medicine, the traditional Chinese medicine is used as an elastic antiperspirant and deodorant material, solves the problem of bromhidrosis from the source, has more obvious and durable bromhidrosis-removing effect, is harmless to human bodies and the environment, and has lower production cost.
The results of the antibacterial property performance test and the deodorization effect test of the bromhidrosis-removing upper garments prepared in examples 1 to 6 of the invention and the upper garments prepared in comparative example 1 are shown in table 1, and it can be seen that the antibacterial property of examples 1 to 6 reaches the standard (GB/T20944.1-2007), the antibacterial rate before washing is more than 99%, the antibacterial rate after washing for 200 times is kept more than 99%, and the deodorization effect is good. In the comparative example, the antibacterial effect was not satisfactory and the deodorizing effect was lost after 200 washes. In conclusion, the deodorant upper garment has antibacterial property and excellent bromhidrosis elimination.
