　　 The outbreak of new coronavirus in just over a year has brought a heavy blow to people all over the world. As the factory of the world, China has played a key role in the global anti epidemic. China takes human life and health safety as its own responsibility, vigorously promotes the research and development and production of vaccines and various antibacterial and antiviral materials, and has made outstanding contributions to the world's fight against the epidemic.

　　 At present, there are basically two kinds of antibacterial textiles: natural fiber and man-made fiber. There are two kinds of anti-bacterial treatment methods: auxiliary treatment and nano chip integration. From the perspective of preparation technology, the source and adhesion process of auxiliaries are the core of additive treatment, and the core of nano particle blending is the preparation process, adding proportion and method of nano particles; No matter which way, the core materials of antibacterial effect are natural extraction and artificial synthesis, and the general effect of natural extraction antibacterial additives is difficult to guarantee; Artificial synthesis is mainly in the form of silver, copper, zinc, titanium and other metal elements and their various compounds, and some of them are heavy metals. Each company presents different product performance according to its own technology. The evaluation of antibacterial products is mainly based on the durability, broad spectrum, safety, antibacterial factor shedding degree, and spinnability of materials, Due to the physical combination of the two mainstream materials and antibacterial treatment methods mentioned above, the adhesion fastness, attachment position, adhesion density and uniformity of antibacterial materials on fibers will be greatly different. Therefore, there will be performance defects in different evaluation dimensions. In addition, most textiles based on natural fibers can only be treated with auxiliaries, The development and changes of antibacterial materials in the past few decades are more reflected in the extraction of additives, processing technology and various nano materials used in slicing. Recently, with the development of science and technology and the investment in research and development, some new materials have emerged,

　　 At present, there is a third kind of antibacterial material. Shanghai Lanbang Industrial Fiber Co., Ltd. has successfully developed a kind of high-performance natural fiber modified by special chemical reaction using cotton as the base material. Due to the co bonding of antibacterial factors and specific molecular chains in cotton fiber, directional modification of the molecular structure, this is a new type of antibacterial textile industry. From the perspective of preparation principle, Some breakthroughs have been made in the problems of antibacterial factors shedding, durability and safety. The experimental results have super antibacterial function, and the antibacterial rate of fungi can reach 99.95%.

　　 At present, Europe, America, Japan and other countries and regions, some categories of clothing (such as socks) antibacterial function demand has been close to 80%. With the development of the epidemic situation and the arrival of the post epidemic era, people pay more attention to and demand for antibacterial products. Antibacterial textiles will continue to penetrate into our daily life, the quality of antibacterial products, the reliability, safety and safety of performance Efficiency is waiting to establish and improve the new functional standards and applicable standards. The survival space of enterprises driven by concept and following the trend of market demand will be compressed. Enterprises with real scientific and technological strength and reliable products will have a bright future.
