Recently, the scientific research team of Professor Chen Yuyue from the School of Textile and Clothing Engineering of Soochow University, after years of scientific research breakthroughs, successfully developed long-acting antiviral and antibacterial textiles, and has achieved industrialized production.
Efficient and long-lasting antibacterial and antiviral properties of natural fiber textile fabrics have always been a difficult problem in the industry. Professor Chen Yuyue's team has been engaged in the research and development of antibacterial textiles for nearly 20 years, especially with in-depth research on the use of nano-silver for antibacterial textiles. After the COVID-19 epidemic in 2020, Professor Chen, inspired by the highly efficient antibacterial function of nano-silver, quickly set about applying antibacterial textile fabric technology to the development of civilian antiviral products. In March last year during the epidemic, Professor Chen and Associate Professor Zhang Desuo obtained the school's consent and entered the Modern Silk National Engineering Laboratory to conduct experimental work on antiviral and antibacterial textiles. After more than two months of research, small-scale production was completed. In May, the products were successfully trial-produced at Jiangsu Wulong Knitting Co., Ltd., and currently, efficient antiviral and antibacterial textiles have been smoothly industrialized.
According to Professor Chen Yuyue, the antibacterial finishing technology currently widely used at home and abroad, although it can effectively achieve antibacterial properties of natural fibers, is mainly limited to surface processing of fiber materials, making it difficult to achieve long-lasting functions and insufficient in wash fastness. The latest scientific research achievement uses the most advanced nano-silver assembly technology, achieving nano-silver assembly inside the fiber through directional penetration of silver ions into the fiber interior and subsequent in-situ reduction, thereby effectively solving the wash fastness problem and achieving efficient antiviral and antibacterial functions. This technology is suitable for cotton, wool, silk, synthetic fiber and other textile materials, and products can be widely used in masks, scarves, underwear and home textiles, with broad market prospects.
The newly developed antiviral and antibacterial textiles have been tested by national authoritative institutions, with an inactivation rate of over 99.7% for various viruses such as H1N1 and H3N2, and an antibacterial rate of over 99% for Candida albicans, Escherichia coli, and Staphylococcus aureus. Moreover, this newly developed cotton knitted antiviral and antibacterial textile has lasting washability. After being placed under natural conditions for 4 months and then washed 50 times according to professional standards by a third-party authoritative testing institution, the antibacterial effect remains above 99%, fully proving the significant antiviral and antibacterial effect and effectively solving the long-term efficacy problem of fabric antiviral and antibacterial properties.
