Jerusalem, Nov. 17 (Xinhua News Agency) - a team from the University of balilan, Israel, used ultrasound to "embed" zinc oxide nanoparticles with antibacterial functions into fabric fibers to form an antibacterial coating. Through this simple treatment, almost any kind of ordinary fabric can be turned into antibacterial fabric, and related technologies are expected to be widely used in the field of antibacterial treatment of medical textiles.
In the laboratory of akhalon gedanken, a professor of Chemistry Department of balilan University, Xinhua News Agency reporter saw the equipment and working principle of antibacterial coating processing technology: an antibacterial material was placed in the groove of a reactor, and with the small "squeak" sound, the white color textiles several meters long kept shuttling back and forth in the reactor.
According to gaidanken, the key to successful antibacterial is the small ZnO nanoparticles. The process of antibacterial coating is mainly a physical process. Without any chemical adhesive, zinc oxide nanoparticles can be firmly bonded together to achieve the goal of highly uniform coating and stable antibacterial performance.
After antibacterial coating processing, medical textiles such as hospital bed sheets, quilts and hospital clothes can become bacterial "insulators", which is expected to greatly improve the health conditions of the hospital and reduce cross infection. In addition, the textile with antibacterial coating can withstand multiple cleaning, and can maintain antibacterial function after being washed 65 times in 92 ℃ water.
According to reports, the antibacterial coating technology has been applied and tested and entered the commercial stage. In 2013, a Bulgarian hospital tested the coated bed sheets, pillowcases and sick clothes, which showed significant antibacterial effect. At present, the small reactor of Professor gedanken's laboratory has been developed into a large-scale production equipment by Brukner textile machinery company of Germany, which is used in the industrial production of textile industry. Sonovia, an Israeli textile technology company, has obtained the right to commercialize the coating technology of antibacterial fabric from the University of balilan. In the future, they will provide the technology, while Brukner Textile Machinery Co., Ltd. will be responsible for the expansion of equipment sales.
Next, gaidanken and his team hope to extend the technology to the research and development of food packaging materials, and "embed" edible antibacterial particles into food packaging bags, so as to extend the shelf life of fruits and vegetables and reduce food waste.
