Description

technical field [0001] The invention belongs to the field of preparation of antibacterial agents and antibacterial fibers, in particular to a preparation method of mesoporous zirconium phosphate-loaded nano copper oxide antibacterial polyester fibers. Background technique [0002] In today's society, the extreme environment, environmental pollution and other ecological environments have seriously deteriorated, and special living microenvironments such as confined spaces have led to an urgent need for functional protective textiles. At present, the fibers used to prepare textiles do not have antibacterial ability, and under certain conditions, they will provide an environment for bacteria to survive and reproduce, threatening human health. The main method to solve the antibacterial problem of fibers is to use antibacterial nanoparticles and polymer matrix for composite modification to prepare modified fibers with antibacterial effects. The fiber will gradually release antiba...
