According to the announcement, the technology of preparing anti-virus and anti-bacterial functional textiles by electron beam grafting has the characteristics of broad spectrum, high efficiency, anti-virus, safety and long-term effect. Anna Nair said on the interactive platform that the company's antiviral and antibacterial fabrics can be used in clothing, home textiles, medical care and other scenes. The production line of antiviral and antibacterial fabrics is under construction and is expected to be mass-produced early next year.
Annell said in the announcement in August that the inhibition rate of electron beam grafting technology on enveloped viruses, bacteria and some fungi exceeded 99%. An article by official website, a cooperative technology company of Shui Mu Juli (Anna Nair), directly mentioned that "the electron beam grafting technology for producing antiviral and antibacterial fabrics has an antiviral rate of 99.89% for COVID-19."
Cailian reporter noted that the above two data are all from the authoritative test report of "the highest biosafety laboratory in China". A professional in the field of chemical industry told Cailian that COVID-19 is an enveloped virus.
According to the data, antivirus mainly refers to inhibiting or destroying the ability of virus to infect host cells, mainly killing enveloped viruses (including influenza, coronavirus, monkeypox virus, etc. ) through the charge adsorption and fixation of the virus and the destruction of the membrane system. The international ISO 18 184 standard is commonly used for antiviral textiles, and the test results meet the corresponding standards, which proves that it has antiviral effect.
The antiviral and antibacterial properties of textiles mainly come from new materials and antiviral and antibacterial finishing agents. The processing methods of antiviral and antibacterial finishing agents are mainly divided into fiber finishing and post-finishing. The latter accounts for about 70% of the processing of antiviral and antibacterial textiles, and usually includes electron beam grafting, surface coating, pad dyeing and microencapsulation.
Li Jie, soochow securities, and others said in the research report released on 65438+February 1 day that at present, 3 1 listed companies have laid out antivirus and antibacterial patents and products. Most of these companies only laid out antibacterial functional fabrics and obtained relevant patents. Only a few companies such as Aner, Mason Clothing, Zhongwang Fabric and Ruyi Group have antiviral patents.
In the application field: 1) children's wear: anti-virus and anti-bacterial functional fabrics used to protect infants, such as Aner and Mason clothing; 2) Adult clothing: fashionable and beautiful, with anti-virus and anti-bacterial functions, such as Blue Ocean House, Biyin Lefen, Bosideng, Taiping Bird, etc. 3) Home textile products: with anti-bacteria, anti-virus, anti-mite and anti-mildew functions, such as Luolai Life, Mercury Home Textiles, Fuanna, etc.
4) Sportswear: pay attention to antibacterial function to prevent a large number of pathogenic microorganisms from breeding after sports textiles are mixed with human metabolites, such as Li Ning, Anta Sports and Xtep International. 5) Other textile manufacturing enterprises: reserve technology, process and sell high value-added antiviral and antibacterial textiles, such as Zhongwang Fabric, Ruyi Group, Lutai A and Taihua New Materials.
It is worth noting that the difficulties of anti-virus textiles are mainly reflected in the fact that the virus has no cell structure, the evolution speed is fast, the research is difficult and the progress is slow. Up to now, there is no relevant standard for testing antiviral textiles in China, and the lag is obvious.
