Antibacterial sanitary finish
On an autumn day in August, it was still horribly hot. Often sweating, sweat secreted contains a small amount of protein, easy to adhere to the skin and clothing to breed bacteria, many people will choose anti-bacteria products. Speaking of antimicrobial, what is antimicrobial? What do antibacterial finishing agents mean?
Antimicrobial: is a general term, including bactericide, bactericide, disinfectant, bacteriostasis, mildew, preservative, etc. The process of killing or impeding the growth, reproduction and activity of microflora by chemical or physical means. It is a general term of bactericide and bacteriostasis.
Development and application of antimicrobial agents
In the 1960s, textiles were mostly made with organic antimicrobials; With the successful development of inorganic antibacterial agents in 1984, the rapid development of antibacterial finishing makes antibacterial agents not only used in fibers and textiles, but also used in plastics, building materials and other products.
Entering the 21st century, with the arrival of the aging society, the number of bedridden old people and home recuperation gradually increases, and the demand for elderly care products to prevent bedsores also shows an increasing trend. Due to the change of concept from a production-oriented society to a living-oriented society, the development and research of products that are beneficial to human health and the earth's environment will be an important topic in the future. Therefore, people are paying more and more attention to antibacterial finishing
Mechanism of action of antimicrobial agents
At present, there are three main antibacterial mechanisms: controlled release, regeneration mechanism and barrier or blocking effect.
The specific antibacterial mechanism is as follows:
At present, we should choose suitable antimicrobial agents around the safety and comfort of application and the durability of performance. As people's environmental protection consciousness enhancement, natural more and more of the agent that fight bacterium to cause the attention of people, such as chitosan, bacteria resistant mechanism for molecular amino adsorption of bacteria, and cell wall surface anion binding, prevent cell wall biosynthesis, antibacterial effect, so as to achieve the natural is still in its infancy stage of the agent that fight bacterium, most of the market is given priority to with series of inorganic antibacterial agent and organic system, technology is relatively mature.
