The sudden COVID-19 epidemic has given people a new understanding of life and health. In the “post-epidemic era”, people are paying more and more attention to new technologies such as antibacterial and antiviral, and they are also paying more attention to textiles with such functions. Since the outbreak, textile companies have also been continuously strengthening the research and development of antibacterial and antiviral functional textiles to help consumers build an effective “protective barrier.”
From fiber to terminal application
Antibacterial fiber
Xinxiang Chemical Fiber Co., Ltd. organized scientific researchers to tackle key problems and successfully developed super-strong and efficient antibacterial regenerated cellulose fiber. The inspection report provided by the National Textile Products Quality Supervision and Inspection Center shows that the antibacterial fiber’s antibacterial rate against Escherichia coli, Staphylococcus aureus and Candida albicans exceeds 99%, which is far higher than the antibacterial index of the national standard for antibacterial fibers. This fiber is made by adding green and highly efficient antibacterial materials to the spinning solution. The physical indicators of the fiber are the same as those of conventional fibers. The fabrics made with this fiber are resistant to washing and have long-lasting antibacterial effects.
Antibacterial fabric
Nanshan Zhishang Company has always been committed to high-end men’s clothing In terms of fabric research and development, not long ago, it successfully developed a fully effective antibacterial wool fabric that can isolate a variety of viruses and bacteria. Wool fiber is a natural protein fiber and a leader among textile fibers. (NASA) In a study published by NASA, wool stood out from many materials due to its natural high breathability, anti-odor resistance, flame retardancy and natural temperature regulation, and was selected as the most suitable for astronauts in space. A medium-fitting fiber. This 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, achieve AA-level protection through physical sterilization, and is safe for skin contact. Based on the concept of sustainability and green development, this fabric uses “green” bio-environmentally friendly antibacterial technology and is highly washable. Clothes made of it can still reach 70%~90% durability after being washed more than 20 times. Highly effective antibacterial ability.
High-end men’s fabrics developed by Nanshan Zhishang
Shandong Ruyi Woolen Garment Group actively conducts research in the face of the epidemic As for new products, it has launched a series of antibacterial protection products, including antibacterial and antibacterial fabrics, and antiviral suits. Among them, silver ion and graphene antibacterial and antiviral series products have achieved customer sampling and mass production.
Antibacterial children’s clothing
A well-known domestic children’s clothing brand (MarColor) Carle uses EcoCos® Antaibei antibacterial fiber to launch a series of children’s clothing with antibacterial functions. This cooperation is a new application of antibacterial fiber in the field of children’s clothing, helping children’s clothing move towards a more fashionable, environmentally friendly and safer direction. Through injection spinning technology, EcoCosy® active antibacterial substances are evenly dispersed on the surface and inside of the fiber to achieve an antibacterial effect by slowing down the survival rate of bacteria and fungi on the surface of textiles. This series of products not only ensures wearing comfort, but also has good antibacterial effect after washing. After strict professional testing, it still maintains high antibacterial effect after being washed 50 times.
Antibacterial home textile products
Affected by the epidemic, people are increasingly Paying attention to the impact of daily consumer products on health, products with antibacterial and antibacterial effects will become a long-term focus of consumers. Towels and other textiles are commonly used in daily life, and their health and safety have attracted more and more attention.
Vosges Towels
Safety and health have always been Vosges Home Textiles One of the hard product indicators that we pay attention to is that before the epidemic, many products of Vosges Home Textiles used antibacterial fabrics. Some even added nano-silver antibacterial additives to the surface of the product fabric fibers, so that they can effectively inhibit a variety of pathogens, such as large intestine. bacilli, Candida albicans and Staphylococcus aureus. After third-party professional testing, the effective antibacterial rate can reach up to 99%. LIFECO, a brand owned by Vosges, takes antibacterial as its theme and specializes in bamboo fiber antibacterial towels. Towels are mainly made of Tianzhu fiber and bamboo-cotton blended products, which have natural antibacterial effects and can effectively inhibit E. coli, etc., with an antibacterial rate of more than 90%. After the outbreak, the company strengthened its layout of healthy antibacterial product lines and launched more products such as antibacterial latex pillows, antibacterial kits and more.
Classification of antibacterial textiles
Why antibacterial textiles can be antibacterial and antibacterial ? This starts with the classification of textiles in this category. At present, antibacterial fibers can be roughly divided into two categories: natural antibacterial fibers and artificial antibacterial fibers. That is to say, some textiles have their own antibacterial functions, while other textiles are artificially endowed with antibacterial and antibacterial functions.
Natural antibacterial fiber
Some natural fibers themselves have antibacterial properties. It has strong antibacterial effect and has a linear macromolecular structure. Common ones include bamboo fiber, hemp fiber, chitin and chitosan fiber, seaweed fiber, etc.
Bamboo fiber
, loading natural mineral antibacterial elements on natural fibers and yarns to achieve antibacterial goals, which is a fiber pre-treatment technology. Natural fibers themselves have the advantages of softness, comfort, durability, breathability, purity, etc. After natural yarns such as cotton are treated with IR micro-element technology, the fibers become softer and more comfortable, and cotton products are less likely to stiffen and harden. The principle of sterilization is free sterilization. When encountering bacteria, it can effectively release sterilization, destroy the cell membrane, cell wall and nucleus of bacteria, and achieve complete killing of bacteria. Based on this technology, Huafang Co., Ltd. has developed highly washable cotton antibacterial products. IR micro-element antibacterial fabrics make the antibacterial active ingredients penetrate into the cellulose molecules through fiber modification, and then use technical methods to tightly combine the antibacterial ingredients into the cellulose molecules, giving the fabric excellent and long-lasting antibacterial properties.
Other antibacterial technologies
Nowadays, more and more research and manufacturing companies have joined in the research and development of antibacterial fibers and textiles. They have developed various new antibacterial technologies to continuously meet consumers’ needs for antibacterial and antibacterial products. The gramin fiber jointly developed by Tianan Group and the Institute of Microbiology of the Chinese Academy of Sciences is a pure bio-based antibacterial fiber based on PHBV. It uses glucose produced from corn starch as the main raw material, cultivates a large number of microorganisms, extracts PHBV, a polyester (similar to mammalian fat) in the microorganisms, and then produces the new fiber through melt spinning. The antibacterial mechanism is to destroy the cell walls of harmful bacteria after contact with bacteria and inhibit the growth of bacteria, thereby truly achieving antibacterial and deodorizing effects. The antibacterial effect of this fiber is long-lasting and will not be significantly reduced due to the increase in the number of uses. It can resist the “superbug” – methicillin-resistant Staphylococcus aureus.
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 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, both enveloped and non-enveloped viruses. “Active oxygen capsule” technology is a strong oxidant sustained-release technology that can slowly release active oxygen with high oxidizing capacity in a natural environment. This technology can embed anti-viral functions into textile fabric fibers, bringing long-lasting effects of inhibiting and killing viruses, and is resistant to washing. Since the use of this product does not require 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.
