In response to the need for Coronavirus (COVID-19) pandemic prevention and control, focusing on fiber materials for emergency protection and public safety, China's national advanced functional fiber technology company: XJXW released a batch of latest research and development results, and innovatively developed new products such as anti-virus masks. The material overcomes the problems of electrostatic adsorption and degradation of traditional masks, and provides new scientific and technological ideas for the prevention and control of Coronavirus (COVID-19) pandemic.
Antiviral masks were developed by loading the nanofibers and outer non-woven fabrics in the mask with antiviral drugs. The product reaches 99% of level 2 protection, has 99% inhibitory rates against Escherichia coli, Staphylococcus aureus, and Candida albicans, and has an antiviral activity of more than 99.9% against H1N1 and H3N2.
Developed a soft support nanofiber membrane, which uses the principle of physical interception and filtration to block viruses, avoids the effect of the elimination of static electricity caused by high-humidity environments and affects the filtration efficiency, and can be reused.
Developed a nanofiber material that can make the virus "lost". The polylactic acid micro-nano fiber gradient structure forms an intricate microporous channel. When the virus passes through, it will be intercepted like a "maze". Its raw material, polylactic acid, can be completely degraded into carbon dioxide and water under certain conditions. There is no solvent in the production process. It has the advantages of renewable and pollution-free, and realizes the high-efficiency and low-resistance performance of the mask.
Develop a new type of bio-based activated carbon fiber composite material. The protective mask prepared based on this material has the characteristics of high adsorption efficiency, strong barrier function, good air permeability, and good bacteriostasis.
Developed graphene-enhanced far-infrared thermal sterilization technology to realize the reusability of nanofiber filter membrane masks.
XJXW actively plays the role of the industry's common technology research and development platform, and continuously integrates innovative resources. In 2020, a total of 31 advanced fiber research and development projects have been carried out. Up to now, 6 key technologies have been broken through and 11 innovative production processes have been formed; 5 achievements have reached batch size The production conditions have been optimized, and one result has been profitable and income-generating. In order to continue to support the research and development of fiber materials and products for emergency protection and public safety, the company will focus on high-barrier, antibacterial and antibacterial fiber materials such as epidemic protection, medical and health protection, and smart fiber materials and their protective materials, which are highly flame-retardant. , Anti-melt dripping, anti-static, anti-ultraviolet and other functional personal protective fiber materials and products, and the detection and evaluation of protective fibers and products.
