Problems solved by technology

However, in recent years, research results have shown that nano-sized heavy metals and compounds and antibacterial polymer nanoparticles have more excellent antibacterial activity, which is due to the unique nano-effects of nano-sized materials, but this nano-sized antibacterial However, reports on the application of agents to textile materials are limited to inorganic metals and their metal compound nanoparticles.
There are few reports on the successful cases of antibacterial polymer nanoparticles applied to textile materials

Abstract

The invention relates to a preparation method for durable anti-bacterial fabric. The preparation method comprises the following steps of synthesis of anti-bacteria monomer, synthesis of anti-bacterialNano-hydrogel, synthesis of surface-modified anti-bacterial Nano-hydrogel, and synthesis of durable anti-bacterial fabric. By adopting the preparation method, the anti-bacterial function of the fabric is achieved by combining Nano-hydrogel particles and the fabric. The treatment process of the method is easy and convenient, is low in damage on the original performance of the fabric; the fabric treated with the method has a durable anti-bacterial effect; the prepared anti-bacterial Nano-hydrogel has a simple treatment process, high biocompatibility, remarkable anti-bacterial effect, no injuryon human bodies, no antibacterial agent, and bacterial resistance.

Description

technical field [0001] The invention belongs to the field of preparation of modified textiles, in particular to a preparation method of durable antibacterial fabrics. Background technique [0002] In recent years, with the continuous emergence of new pathogens, the impact of microbial contamination and disease spread caused by bacterial pathogens on human health and life has become more and more serious, and antibacterial research is urgent. [0003] Generally speaking, the surface of materials provides a good medium for the growth of various bacterial pathogens, and the proliferation of bacterial pathogens will have various adverse effects on human safety. Survey data show that after antibacterial treatment on the surface of materials, the probability of microbial contamination and infection will be significantly reduced. Therefore, it is very necessary for the materials used in our daily life to undergo antibacterial modification treatment, so that people's healthy life c...
