Therefore, the development of the fabric with lasting antibacterial and bacteriostatic properties has wide development prospect. At present, the antibacterial agent mainly comprises three types of inorganic antibacterial agents, organic microbial agents and natural antibacterial agents. The antibacterial effect and safety of natural antibacterial agents and organic antibacterial agents cannot be guaranteed, and the inorganic antibacterial agents are poor in binding force with textile fibers, can only be adsorbed on the surfaces of the fibers or among interweaving points of textiles when being directly used, and can easily fall off from the fibers once being washed by water to reduce or even lose antibacterial property. However, the inorganic antibacterial agent is mainly a silver ion antibacterial agent, silver ions are non-metabolizable substances of human bodies and are harmful to human bodies accumulated in the human bodies, and after the antibacterial fabric treated by the inorganic antibacterial agent is washed for many times, the antibacterial rate is obviously reduced, and the lasting and efficient antibacterial effect is difficult to maintain.
