Abstract

The invention discloses a multifunctional nano-inorganic composite antibacterial agent for fabric finishing, a preparation method and an application thereof, and relates to the technical field of fabric antibacterial. The multifunctional nano-inorganic composite antibacterial agent for fabric finishing provided by the invention uses g-C 3 N 4 Coating nano-zinc oxide can improve the antibacterial ability of ZnO under visible light conditions and expand its application range; 3 N 4 The coated nano-zinc oxide is carboxylated to obtain an antibacterial agent. This antibacterial agent can directly react with the hydroxyl groups on the fabric through finishing, so that the nano-zinc oxide antibacterial particles can be combined on the fabric to the greatest extent. At the same time, the nano-particles and the fabric It is chemically bonded to give the fabric durable antibacterial properties. The fabric antibacterial finishing method provided by the invention uses the multifunctional nano-inorganic composite antibacterial agent for fabric finishing to finish the fabric, the method is simple, and the water resistance and antibacterial durability of the fabric are greatly improved.

Description

technical field [0001] The invention relates to the field of fabric antibacterial technology, in particular to a multifunctional nano-inorganic composite antibacterial agent for fabric finishing, a preparation method and an application thereof. Background technique [0002] With the improvement of living standards, people pay more and more attention to the quality of life, hoping to obtain comfortable and safe clothing, as well as a hygienic and healthy living environment. People's requirements for clothing are not only cold and warm, but also fashionable and beautiful. Functional, safe and healthy textiles have gradually been favored by people. Cotton, fiber, etc. have the advantages of good air permeability, soft hand feeling, excellent hygroscopicity, renewable and biodegradability, etc., so they become the most consumed natural fibers. Natural fibers are easy to absorb moisture, and under suitable temperature and humidity, they can provide a large amount of nutrients fo...
