The excellent properties of silicone products have led to rapid development as a polymer material. At present, the development direction of silicone is high performance, multi-functionality and compounding. The synthesis of silicone products is mainly achieved by the following methods: First, by selecting different organic groups and silicon atoms to combine to improve the performance of a certain aspect. The second is secondary processing through various chemical or physical means to obtain silicone products of different uses and forms. For example, various copolymerization techniques such as graft polymerization, block polymerization, interpenetrating network polymerization, etc. are used to change the molecular size and shape of the polysiloxane, and different curing methods such as peroxide curing, dehydrogenation reaction, dehydration reaction, and desorption are employed. Alcohol reaction, ultraviolet curing, electron beam curing, etc. change their application conditions, and their morphology is changed by using techniques such as emulsification, filling, and kneading [46] .
In modern life, microorganisms, such as bacteria, mold , and yeast, are almost everywhere. With the improvement of human living standards, human beings are increasingly aware of their own health and environmental protection. Microorganisms are highly prone to reproduction on textiles. They are close to the human body and are a warm and humid environment. The microenvironment composed of sweat and other secretions, fats and dander provides ideal conditions for the reproduction of microorganisms. In order to maintain hygiene, maintain Good health has important practical significance for the study of antibacterial products [47] .
During the Second World War, soldiers wearing uniforms containing quaternary ammonium antibacterial agents reduced the secondary infection rate after injury, which was the first large-scale use of modern antibacterial materials. After the 1960s , antibacterial fibers began to appear, and the antibacterial agents used were chemical substances with strong antibacterial properties. A new generation of sanitary finishing agent DC-5700 , which was launched by Dow Corning in 1975 and its Bioguard TM trademarked textile developed in collaboration with Burlington , opened a new page in the field of sanitary finishing agents, marking the hygiene finishing agent. Development has entered the beginning of a new phase characterized by low toxicity and durability. One after another after entering the antimicrobial agent market are Ciba - Geigy Irgasan DP-300 (Triclosan), ICI's Reput t er20 (PHMA) and Japan's Miki in the research development of HPDE and a number of dissolution sanitary finishing agent. 20 Since the late 1980s, for security reasons, multi-use silicone quaternary ammonium salt play fiber coupling agent, in order to achieve the purpose of anti-bacterial. With the continuous efforts of people, especially the introduction of preparation methods for innovative antibacterial new materials, such as organic - inorganic composite materials, nanotechnology, etc., antibacterial technology will be continuously improved and improved [48-49] .
The origin of antibacterial materials in China can be traced back to ancient people using silver or copper containers to store water to inhibit water deterioration. In the early 1980s, China began to pay attention to the application of antibacterial finishing agents. Some domestic research institutes and universities have carried out many fruitful scientific research work, and have developed a wide variety of silicone sanitary finishing agents. Shanghai Resin Factory first developed the silicone anti-mold finishing agent SAQ-1 , the anti-mite anti-bacterial agent AM-500 developed by Xingzhou International Group Co., Ltd. , STU-AM101 developed by Shandong University, developed by Ningbo Chemical Research and Design Institute. Silicone Sanitary Finishing Agent NBMSI-4 , KGS-999 developed by Chongchuan Keguang New Materials Research Institute of Nantong City , and antibacterial finishing agent developed by Cai Xiang, Zhou Yupeng, etc., the development space of antibacterial materials in China It is very big . China's accession to the WTO also provides a good opportunity for the development of antibacterial technology. In the near future, the application technology of antibacterial agents in fabrics and plastics will be more mature. Antibacterial materials will also be used in home appliances, kitchen supplies, daily necessities, and chemical building materials. , public facilities and other fields have been widely used. As a new type of functional material, it is of great significance to improve the living environment of human beings and improve the quality of life [50] .
