In foreign countries, the use of metal ion antibacterial agents such as silver and other harmful antibacterial agents has been prohibited by the European and American markets for a long time. Therefore, the development of non-toxic, harmless and antibacterial textiles with zero addition of antibacterial agents becomes a focus of attention of the market.
In order to solve the problems, the scheme is developed accordingly.
