The antiviral and antibacterial rate of textile fabrics reached above 99%, and the washing effect was still significant. Recently, Professor chenyuyue, Professor of textile and Clothing Engineering College of Suzhou University, has successfully developed long-term antiviral and antibacterial textiles through years of scientific research and research, and has realized industrial production.

The high efficiency and long-term antibacterial and antiviral of natural fiber textile fabric has been a difficult problem in the industry. Professor Chen Yuyue team has been engaged in the research and development of antibacterial textiles in recent 20 years, especially the in-depth research on nano silver used in textile antibacterial. After the 2020 covid-19 outbreak, Professor Chen Yuyue inspired the antibacterial fabric technology to apply to the development of the civilian antiviral products according to the inspiration of nano silver with high antibacterial function. During the March epidemic, Professor Chen Yuyue and vice professor Zhang delock, with the consent of the school, entered the modern silk National Engineering Laboratory for the test of antiviral and antibacterial textiles, and completed the production of small samples after more than two months of tackling key issues. In May, the products were successfully tested in Jiangsu Wulong Knitting Co., Ltd. and the industrial production of high efficiency antiviral and antibacterial textiles has been realized.

According to Professor chenyuyue, although the antibacterial finishing technology widely used at home and abroad can effectively realize the antibacterial of natural fiber, its main technology is mainly limited to the surface processing of fiber materials, which is difficult to achieve long-term function and lack of washing fastness. The latest research results adopt advanced nano silver assembly technology, through the directional penetration of silver ions into the fiber, and then in-situ reduction, the nano silver assembly in the fiber is realized, thus effectively solving the problem of washing fastness and realizing the high-efficiency anti-virus and antibacterial function. This technology is suitable for cotton, wool, silk, chemical fiber and other fabrics. The products can be widely used in masks, scarves, underwear and home textile products, and have a broad market prospect.

The anti-virus and antibacterial textiles developed in this research and development have been tested by the state authority, and the inactivation rate of the products to H1N1, H3N2 and other viruses is over 99.7%, and the antibacterial rate of the products to Candida albicans, E.coli, Staphylococcus aureus and other bacteria has reached more than 99%, and the newly developed and produced all cotton knitted anti-virus anti-bacterial textiles have long-lasting washability, After being washed for 4 months under natural conditions and washed again by professional standards of the third-party authoritative testing institution 50 times, the antibacterial effect is still over 99%, which fully proves the remarkable effect of antiviral and antibacterial, and effectively solves the long-term problem of antiviral and antibacterial of fabrics.

It is understood that Professor chenyuyue's research team has been engaged in the research of antibacterial textiles for many years, and has obtained more than 20 patent licenses for invention in the field of nanomaterials research, and has been supported by the national major scientific research plan (863 plan) and National Natural Science Foundation Project in 2012 respectively. The results have been applied in the field of medical materials for many years, The relevant achievements were awarded the first prize of science and technology progress of China Textile Industry Federation and the third prize of Jiangsu Province Science and technology progress in 2019 in 2013. In the first half of this year, its related technologies were supported by the national advanced functional fiber innovation center.
