Xie Xiaobao, director of Guangdong microbial analysis and detection center

Antiviral textiles and their detection methods are the focus of the industry. The significance of research and development of anti-virus textiles is to reduce the spread of virus and reduce the harm of sudden and epidemic virus. Textiles have the function of preventing virus and protecting human body.

Because of its structure and use characteristics, textiles are particularly easy to be attached to viruses. Therefore, the use of anti-virus textiles to make them lose infective activity is a good way to block the transmission of viruses to human body.

In 2014, the international organization for Standardization (ISO) issued the standard for testing antiviral fabrics (iso18184). The release of this standard indicates that the international standard system of functional textiles has been further improved.

In 2016, Japan formulated the standard of "JIS l1922-2016 textiles textiles anti virus performance test" according to iso18184.

In 2019, ISO changed iso18184. Subsequently, the United Kingdom also issued the BS iso18184-2019 standard.

At present, there is no relevant standard for anti-virus testing of textiles in China.

In August 2020, the standard of "anti viral functional textiles" organized by health textile branch of China Health Care Association, approved by China Health Care Association and participated by Guangdong microbial analysis and testing center and other units, is currently under development.

Jiang Yan, general manager of Changzhou henglibao nano New Material Technology Co., Ltd

The antibacterial mechanism of graphene is believed to be oxidative stress and nanoknife effect on cell membrane. However, related experiments have proved that graphene sheet can interact with cell membrane and suck out the phospholipids in the cell, leading to the death of bacteria. This interaction is also related to the lamellar size. The larger the size, the stronger the effect, the better the antibacterial property. This theory also confirmed the importance of graphene size against bacteria.

Due to its unique physicochemical properties, graphene not only has certain antibacterial activity, but also can be used as the support substrate of antibacterial nanoparticles to reduce the agglomeration of nanoparticles and improve its stability and antibacterial activity. In order to improve the antibacterial activity and stability of graphene and reduce its potential ecological toxicity, the company synthesized the modified graphene basic antibacterial PA6 composite material by modified chemical bonding and non covalent bonding methods.

At present, graphene is considered to be the most suitable antibacterial agent in contact with human skin. The results showed that graphene existed in the fiber by chemical bonding, and the antibacterial effect was not affected by washing times.

The antibacterial mechanism of graphene mainly includes: the sharp edge of graphene can be directly inserted into bacterial cell membrane for cutting; graphene with two-dimensional structure has high surface energy, which can directly extract phospholipid molecules on cell membrane, causing cell membrane damage and killing bacteria; carbon nano materials produce oxidation stress, resulting in glutathione oxidation.

Size dependent biological effects of graphene nanomaterials. There was a positive correlation between the cytotoxicity of graphene oxide and its concentration: at low concentration (20 μ g / ml), only large pieces of graphene oxide had obvious cytotoxicity. With the increase of concentration, the cytotoxicity of large-scale graphene oxide increased rapidly, and when the graphene oxide was small, only 20% cytotoxicity was found at 100 μ g / ml, which indicated that the small-sized graphene oxide had the best biocompatibility.

There is a direct relationship between the cytotoxicity of graphene and the size of graphene sheet, and the larger the size of graphene, the stronger the toxicity.

When go interacts with cells for a short time, it will cause mechanical damage to the cell membrane, so it shows toxicity. However, with the decrease of the size, the sharpness of go lamellae decreases, so the small size has little lethality to cells.

The anti-virus principle of the fabric is: graphene can catalyze oxidative stress reaction of virus, leading to virus death. As a magic fiber, single-layer graphene multifunctional composite fiber has only one aspect of anti-virus function, but also has multiple composite functions, such as antibacterial, far-infrared self heating, anti ultraviolet, anti mite, negative ion and so on.

Yiwu Yingtong Textile Technology Co., Ltd. partner Tan Hui

Under the normalization of the epidemic situation, with the continuous strengthening of consumers' health awareness, people's awareness of health knowledge, textile antibacterial principle and products has been continuously improved. The products developed by health production enterprises are more diversified, with more real and effective functions, providing a development stage. The development of textiles will become meaningless without comfort.

Coolmous? Fiber developed by the company maintains its original antibacterial properties and other functional properties by compounding other functional powders. The product has precise antibacterial properties. The addition of polyguanidine salt in the fiber can make the product have antibacterial function through physical contact antibacterial. Organic antibacterial fiber has more accurate, rapid and efficient inhibition effect against fungi and virus strains, which is different from the broad-spectrum antibacterial fiber on the market at present. With the deepening of people's understanding of antimicrobial agents, broad-spectrum antibacterial is no longer a real demand of consumers. Consumers have come to realize that the broad-spectrum antibacterial and undifferentiated sterilization can not only eliminate harmful bacteria, but also inhibit the survival of beneficial bacteria which can protect human body. It is harmful to human health more than good.

Professor Jin Lian Hu, City University of Hong Kong

At the same time, it also faces the risk of environmental pollution and long-term retention by human body. In the future, the development trend of antibacterial and antiviral textiles is highly efficient environmental protection and ecological development.
