The clothes we wear are exposed to viruses and bacteria every day, and can become the medium of infection if we are not careful. Journalists learned from Soochow University on the 24th that a textile fabric with antiviral and antibacterial rates of more than 99% and still maintain remarkable effect after repeated washing has been successfully developed and industrialized.
The efficient and long-term antibacterial and antiviral effect of natural fiber textile fabrics has always been a difficult problem in the industry. According to Professor Chen Yuyue of College of Textile and Clothing Engineering of Soochow University, the antibacterial finishing technology commonly used at home and abroad is mainly realized through the surface processing of fiber materials, which is difficult to achieve long-term antibacterial function, and there are also deficiencies in the fastness to washing. And he used the most advanced nano-silver assembly technology, through the directional penetration of silver ions into the fiber, and then in-situ reduction, realized the nano-silver assembly in the fiber, thus effectively solving the problem of fastness to washing, and realizing the high-efficiency antiviral and antibacterial functions. This technology is suitable for cotton, wool, silk, chemical fiber and other textiles, and the products can be widely used in masks, scarves, underwear and home textile products, with broad market prospects.
Tests by national authorities show that the inactivation rate of this antiviral and antibacterial textile product against various viruses such as H1N1 and H3N2 is above 99.7%, and the antibacterial rate against bacteria such as Candida albicans, Escherichia coli and Staphylococcus aureus is above 99%. Moreover, this newly developed and produced pure cotton knitted antiviral and antibacterial textile has lasting washability. After being placed under natural conditions for 4 months and washed for 50 times by the professional standard of a third-party authoritative testing organization, the antibacterial effect of this textile is still above 99%, which fully proves the remarkable antiviral and antibacterial effect and effectively solves the long-term problem of antiviral and antibacterial of fabric.
Professor Chen Yuyue's team has been engaged in the research and development of antibacterial textiles in the past 20 years, especially in the application of nano-silver in textile antibacterial research. After the COVID-19, Chen Yuyue quickly applied nano-silver antibacterial textile fabric technology to the development of civil antiviral products. In May this year, the product was successfully put into trial production in Jiangsu Wulong Knitting Co., Ltd. At present, the industrialization of high-efficiency antiviral and antibacterial textiles has been successfully realized. (Correspondent: Ding Shan, Journalist: Zhang Ye)
