In recent days, with the effective control of the new coronavirus pneumonia epidemic in our country and the sufficient supply of epidemic prevention materials, people’s lives and work have gradually returned to the previous rhythm. This epidemic has given people a new understanding of anti-epidemic materials. After the epidemic, people have paid more attention to textiles with antibacterial functions, and new technologies such as antiviral have also entered the public’s field of vision. In dealing with the challenges of bacteria and viruses, these antibacterial textiles are building another layer of “protective barrier” for us.
High-end textile fabrics & household towel products
Introduction to antibacterial textiles Public view
Nanshan Zhishang Company is committed to the research and development of high-end men’s clothing fabrics. Not long ago, Nanshan Zhishang successfully developed a fully antibacterial wool fabric that can isolate a variety of viruses and bacteria.
As we all know, wool fiber is a natural protein fiber and a leader among textile fibers. In a study published by NASA (National Aeronautics and Space Administration), wool stands out from many materials due to its natural advantages such as high breathability, anti-odor, flame retardant and natural temperature regulation. Selected as the most suitable fiber for astronauts to wear next to their skin in space.
Nanshan Wool Fabric uses Australian Merino wool. This product named “Nanshan Healthcare Antibacterial Wool Fabric” is woven using high-tech wool yarn processing technology. In addition to ensuring the unique advantages of wool fabric products, this fabric product can block a variety of bacteria and has a protection level of AA. The protective effect is achieved through physical sterilization, and it is safe to touch the skin.
Based on the concept of sustainability and green development, the fabric uses “green” bio-environmentally friendly antibacterial technology and has high wash resistance. The finished clothes can still achieve 70% to 90% sustained and efficient antibacterial ability after being washed more than 20 times.
Judging from the current situation, people think most about health issues in their daily consumption. Products with antibacterial and antibacterial effects will become a long-term focus of consumers in the future. Affected by the epidemic, towels are a commonly used textile in daily life, and people will pay more attention to their safety.
Safety and health have always been one of the rigid product indicators that Vosges Home Textiles brand pays attention to. Before the epidemic, many of Vosges Home Textiles’ main accessories products (such as Jiaqi, Xinshang, Such as Maple series) uses high-quality antibacterial fabrics, and evenly adds nano-silver antibacterial additives to the surface of the product fabric fibers, so that it can effectively inhibit a variety of bacteria, such as Escherichia coli, Candida albicans and Staphylococcus aureus. Professional testing from three parties shows that the effective antibacterial rate can reach up to 99%. It has achieved good sales and reputation in the market.
Take a bamboo pulp fiber antibacterial towel from Vosges as an example. Bamboo pulp fiber is a regenerated cellulose fiber produced using bamboo as raw material. It has The antibacterial effect, coupled with Japan’s new generation antibacterial technology, makes the product have excellent antibacterial effect, which can effectively inhibit Escherichia coli and Staphylococcus aureus, with an antibacterial rate of more than 90%.
After resuming work and production, Vosges has continued to strengthen its product line layout focusing on health and antibacterial aspects, such as Vosges cotton soft towels, antibacterial latex pillows, antibacterial kits, etc. In addition, in response to the current situation of the epidemic, the Jieyu brand is also focusing on promoting the “antibacterial” series of products. Focusing on the concept of protecting safety, consumers are educated on the good towel usage habits of using towels in pairs, using them for different purposes, and changing them regularly.
Textile technology that can resist viruses
Traditional industries play with ” “Black Technology”
In addition to giving new “antibacterial” functions to original products, some companies have also improved the antiviral properties of textiles by developing new technologies. These “black technologies” “Technology” has given new vitality to traditional industries.
Since the outbreak, the patented “active oxygen capsule” technology developed by Hong Kong New River Holdings has been used in masks and textiles, which can effectively prevent the spread of bacteria and viruses. This feature will expand some new application areas for the product, especially the anti-viral textiles, anti-viral masks and medical textile markets.
According to Robin, the marketing director of Xinhe Holdings, multiple experimental tests have shown that textiles treated with “active oxygen capsule” technology have obvious killing effects on a variety of viruses, regardless of whether Is it for enveloped viruses or non-enveloped viruses?
The “active oxygen capsule” technology is a slow-release technology for strong oxidants, which can slowly release active oxygen with high oxidizing capacity in the natural environment.
Reactive oxygen species is a strong oxidant that can kill a wide range of microorganisms, including bacteria, spores, viruses, fungi, etc., and its killing speed is faster than that of chlorine 600~3000 times faster. As we all know, Class 84 disinfectants have a very good killing effect on the new coronavirus. The mechanism of action isThe hypochlorous acid produced by 84 disinfectant has strong oxidizing properties and can oxidize the nucleic acid material of the virus, thereby killing the virus. However, Class 84 disinfectants are not suitable for anti-viral finishing of textiles and clothing. One of the reasons is that the action time is very short, and the disinfection effect disappears quickly when added to textiles. Another reason is that 84 disinfectant contains hypochlorous acid, which is allergenic, corrosive and oxidizing. If you are exposed to 84 disinfectant for a long time, it will harm human health.
The “active oxygen capsule” technology can implant anti-viral functions into the fibers of textile fabrics, bringing long-lasting effects of inhibiting and killing viruses, and is resistant to washing. Since the use of this product does not require the use of any adhesive, it will basically not affect the comfort and softness of the fabric. It is not only suitable for the medical protection field, but also for the fashion and leisure field.
Swiss HeiQ Innovative Textile Technology Company (HeiQ), which has repeatedly won the Swiss Technology Award and the Swiss Environmental Protection Award, successfully developed antiviral and antibacterial textile treatment technology HeiQ Viroblock NPJ03 during the epidemic. (referred to as “Viroblock”), has a significant effect against coronavirus.
Masks treated with this technology greatly reduce the risk of human coronavirus (229E), influenza viruses H1N1, H5N1, H7N9 and respiratory syncytial virus (RSV) ) contagiousness. Among them, in tests against human coronaviruses, masks treated with Viroblock reduced viral infectivity by more than 99.99%.
According to reports, Viroblock combines vesicle and silver technologies to inhibit the growth and retention of bacteria and viruses. Viroblock vesicle technology targets lipid-developed viruses such as coronaviruses and can quickly kill viruses, while Viroblock silver technology can inhibit the replication of bacteria and viruses. Viroblock can be used on a variety of textile surfaces, including masks, air filters, medical gowns, curtains, and more.
It is understood that American tights and socks manufacturer Kayser-Roth plans to add this technology to its new products. Many international textile manufacturers such as China Lufeng Textile and Dyeing Co., Ltd. are evaluating the use of Viroblock in other types of fabrics for clothing.
Knowledge Popularization
Why antibacterial textiles are antibacterial (antibacterial) ?
The first is to use some natural fibers and metal fibers (silver, copper, nickel-chromium alloy and other metal fiber bundles) Has its own antibacterial properties, such as kapok fiber, hemp fiber, bamboo fiber, etc., such as hemp fiber, which contains cannabinoids and has antibacterial properties; and hemp is a hollow fiber and rich in oxygen, making it difficult for anaerobic bacteria to survive, similar to In kapok. Flax fiber has a significant antibacterial effect. The antibacterial rate against Pseudomonas aeruginosa and Candida albicans can reach more than 65%, and the antibacterial rate against Escherichia coli and Staphylococcus aureus exceeds 90%. Apocynum fiber has an inhibitory rate of 40% to 60% against Staphylococcus aureus, Candida albicans, etc., and has good antibacterial properties.
The second is to use padding, dipping, coating or spraying methods to prepare antibacterial additives. The antibacterial effect of this method is not durable, and the antibacterial effect is easily weakened or disappeared during wearing (such as washing, sun exposure, friction), but it is convenient, simple and easy to operate, and has a wide range of applications, including chemical fibers and natural fibers.
The third method is to modify the interior or exterior of the fiber, such as adding antibacterial finishing to chemical fiber spinning. Agents or grafting antibacterial groups onto the fiber surface. This method requires high technology, complex operations, advanced equipment, long-lasting antibacterial properties, and high costs.
The above three organizing methods have their own advantages and disadvantages. The first one is the most environmentally friendly and healthy, and is more popular among consumers at this stage. Acceptable, but the antibacterial effect is relatively weak and restricted by the wearing properties of the fiber itself; the latter two mainly exert antibacterial (bacterial) effects on the fabric itself through the action of antibacterial finishing agents, and are the most widely used, and their antibacterial (bacterial) effects It has a lot to do with the selection, measurement and arrangement of antibacterial agents. Common antibacterial agents such as silver ions and chitosan on the market fall into the latter two categories.
