Background

The textile is easy to breed bacteria, mould and other microorganisms in the using process, and the antibacterial textile not only can effectively prevent the textile from being damaged by the harmful bacteria, but also can well protect the health of a user, such as preventing underwear from generating peculiar smell, preventing fungi on socks from growing and breeding, preventing infants from generating erythema due to contacting diapers and the like. Along with the improvement of living standard of people, the consciousness of preventing diseases and resisting diseases of people is generally enhanced, and the textiles with the antibacterial function are more and more favored by people. The preparation of the antibacterial functional textile usually comprises the step of processing the antibacterial agent on the textile by means of blended spinning or functional finishing and the like.

Antibacterial agents for textiles are mainly: organic antibacterial agent, inorganic antibacterial agent, and natural antibacterial agent. These antibacterial agents are characterized by, for example: most of the organic antibacterial agents are quaternary ammonium salts, guanidines, fatty acids, metal compounds and the like, and most of the organic antibacterial agents are toxic and not environment-friendly; inorganic antibacterial agents, particularly silver-based antibacterial agents, are preferred because of their excellent heat resistance and broad-spectrum antibacterial properties, but they have a certain cytotoxicity and are likely to cause skin problems with long-term use. The existing organic antibacterial agent, inorganic antibacterial agent and natural antibacterial agent are difficult to simultaneously meet the basic conditions of broad spectrum, high efficiency, safety, washability, environmental protection and the like.
