Description
Technical Field
The invention belongs to the technical field of medical disinfectants, and particularly relates to a wet tissue for wiping an object surface.
Background
In recent years, people are becoming more aware of the hazards of "multiple pathogens". "multiple pathogens" represent a major challenge in the public health field. The world health organization has proposed a series of pathogenic bacteria to facilitate research and development in the field of antibiotics. The excessive and inappropriate use of antibiotics is the main cause of bacterial resistance. Nowadays, 890 multiple pathogens have been found, the number of which far exceeds the number of antibiotics used to combat them. This is mainly because the rate of resistance development by bacteria is much higher than the rate of development of new and effective drugs. Although selective use of antibiotics can solve this problem to some extent, prevention of bacterial infection is the most effective way. Once a single bacterium has propagated to form a biofilm, the extracellular matrix can instead play a protective role, which is beyond the normal immune range of the human body, and it is difficult for antibiotics to inhibit its growth. Studies have shown that antibiotics in excess of 1000 times the normal dose kill bacteria entrapped within the biofilm. Therefore, the antibacterial material has a good application prospect in the fields of public health, medical treatment, food packaging and the like, can effectively prevent bacteria from adhering and breeding, and reduces harm to human health.
Wet wipes are essential fast-moving products for modern people, and are almost involved every day. With the reduction of the resistance of infants and children, the microbial safety of the external environment becomes a great threat to the physical health of infants and children, and therefore, the consumption demands of the anti-bacteria wet tissue are increasing. The common non-woven fabrics are generally adopted in the anti-bacterial and bacteriostatic wet tissues on the market, the common non-woven fabrics generally adopt viscose components with formaldehyde slow release, and formaldehyde is easy to detect. Secondly, in order to achieve the anti-corrosion effect, a preservative is generally added into the wet tissue solution. Thirdly, in order to achieve the anti-bacterial and bacteriostatic effects, bacteriostatic components capable of causing the denaturation of microbial proteins or destroying the reverse permeability of cell membranes are added into the wet tissue liquid. The obtained anti-bacteria and bacteriostatic wet tissue is easy to consume anti-bacteria and bacteriostatic components, has difficult maintenance of performance, is allergic due to addition of more bacteriostatic agents or preservatives, and can cause drug resistance of microorganisms.
