Abstract

The invention relates to the field of antibacterial fabric materials, and discloses a preparation method of a composite antibacterial agent and application of the composite antibacterial agent to a polyester fabric. The preparation method of the composite antibacterial agent comprises the following steps that (1) amino modified nano zinc oxide is mixed with a halogen compound for a reaction to obtain halogen modified amino nano zinc oxide; and (2) the halogen modified amino nano zinc oxide and the antibacterial agent are mixed in an organic solvent, a catalyst is added, and a polymerization reaction is carried out under the action of the catalyst to obtain a nano zinc oxide halamine composite antibacterial agent. The antibacterial fabric prepared from the antibacterial agent has efficient antibacterial and deodorizing capacity.

Description

technical field [0001] The invention relates to the field of antibacterial fabric materials, in particular to a preparation method of a composite antibacterial agent and its application on polyester fabrics. Background technique [0002] In the face of various global public health events with more and more far-reaching impacts, the concept of health has gradually penetrated into the hearts of consumers, and subsequently, they have become more focused on "health and safety" in all aspects of "basic clothing, food, housing and transportation". As we all know, the body's metabolism needs perspiration very much, and there will be certain metabolic waste in our sweat, so to a certain extent, "sweating" has the effect of "detoxification". However, the accumulation of a large number of inorganic substances in sweat will change the pH value of the skin and cause certain damage to the skin. And under suitable temperature and humidity conditions, the organic components in sweat accum...
