After the outbreak of the epidemic, the company strengthened the layout of the healthy antibacterial product line, such as antibacterial latex pillow, antibacterial kits and more products.

Classification of Antibacterial Textiles

Why can antibacterial textiles fight bacteria and inhibit bacteria?

This should start from the classification of this category of textiles.

At present, antimicrobial fibers can be roughly divided into two categories: natural antimicrobial fibers and artificial antimicrobial fibers. That is to say, some textiles have antimicrobial functions, while others are artificially endowed with antimicrobial and bacteriostal functions.

● Natural antibacterial fiber

Some natural fibers themselves have antibacterial function, its antibacterial effect is strong, with linear macromolecular structure, common bamboo fiber, hemp fiber, chitin and chitosan fiber, seaweed fiber, etc.

Artificial antibacterial fiber

Artificial antimicrobial fibers can be added to the fibers by means of blending spinning, composite spinning, grafting modification, ion exchange, wet spinning and post-finishing, so as to obtain antimicrobial function.

These include natural antimicrobial ingredients extracted from plants, such as natural minerals, metal ions, graphene, etc.

Add natural antibacterial ingredients

In recent years, some plants containing antibacterial ingredients, such as aloe vera, isatidis root, tea, wormwood, mint, etc., have been gradually used to make antibacterial fibers.

Yibin Huimei Fiber New Materials Co., Ltd. extracts a variety of tea polyphenols such as theaflavin, thearubicin and theofubicin from natural tea, and dispersions these substances evenly into the textile fiber to prepare tea fiber.

Because the active components of tea polyphenols have natural antibacterial and deodorant functions, the fiber and its manufactured products have good antibacterial effect.

Weiqiao Textile has developed Avi antibacterial yarns and fabrics, among which the antibacterial function is provided by wormwood antibacterial bamboo fiber.

The antimicrobial fiber is a new kind of antimicrobial fiber made by adding the antimicrobial extract of Artemisia argyi into bamboo pulp fiber.

Germany Zimmer Company based on Lyocell fiber processing technology, in the spinning solution to add very fine seaweed, developed a kind of Seacell active fiber.

The addition of these algal substances makes the fiber have a good adsorption ability to metal ions, so that the fiber has a good antibacterial function.

Graphene, stripped from carbon materials, is a two-dimensional crystal composed of carbon atoms that is only one or multiple atoms thick. It has very excellent and unique physical and chemical properties.

The graphene (biomass) composite polyester fiber launched by Jinan Shengquan Group Co., Ltd. is made of biomass graphene and polymer blended spinning yarn. It not only has antibacterial function, but also has anti-static, far-infrared, anti-ultraviolet and other characteristics. It can be used in underwear, home textile, medical care and other fields.

During the epidemic, Shengquan Group used biomass-graphene-SS composite non-woven fabric as the skin-friendly layer of the mask, which can improve the antibacterial and adsorption capacity of the non-woven fabric and make the protective effect better.

After the inspection by the authority, the disposable bio-graphene mask independently developed and produced by Shengquan Group has passed the FDA certification and obtained the qualification for export to the United States.

Changzhou Henglibao Nano New Materials Co., Ltd. uses natural graphite as raw material to prepare functional graphene by special process, and then prepares graphene-modified nylon slices by in-situ polymerization, and then prepares graphene-modified polyamide 6 fibers by melt spinning.

The fiber also has antibacterial properties and can be used in sportswear, underwear, socks, etc.

Not long ago, Changzhou Henglibao and Fujian Yongrong Jinjiang Co., Ltd reached a comprehensive strategic cooperation on graphene polyamide 6, to help science and technology into huge productivity, the new graphene materials will be more applied to the field of clothing and apparel.

Bamboo charcoal can also be used as antibacterial material in the development of antibacterial products. Quanzhou Haitian Material Technology Co., Ltd. calcines white bamboo charcoal from natural bamboo at a high temperature above 800℃, and then grinds it into ultra-fine nano powder, which is integrated into polyester to produce white bamboo charcoal yarn with antibacterial effect.

And then according to a certain proportion of synthetic cotton and spandex blend woven into white bamboo charcoal fabric, with antibacterial deodorant, negative ion emission and ultraviolet resistance, heat storage and heat preservation, low carbon environmental protection and other functions and characteristics, can be used in underwear, shirts, T-shirts, socks, sports casual wear, towels, bedding and other fields.

It was detected that the fabric inhibited the growth of Staphylococcus aureus by 99.1% (antibacterial grade A) before washing.

The growth of Candida albicans (64%) and Escherichia coli (97%) could still be inhibited by washing 50 times.

Triporous™, a porous carbon material with a unique microstructure, has been made from rice husks.

With three different pore sizes, Triporous™ can easily adsorb macromolecular materials, such as high molecular weight organic compounds that are difficult to adsorb with conventional activated carbon, as well as low molecular weight compounds at high speeds.

Sony has begun licensing Triporous™ to the FIBER and apparel industries and will develop products using the Triporous Fiber ™ trademark.

Not only does the deodorant function last longer, but it also restores deodorant by desorbing particles from the laundry process, and has antimicrobial and bacteriostatic properties, such as inhibiting bacteria such as Mora bacteria, which are the source of unpleasant odors in semi-dry clothing.

IR microelement technology is a compound inorganic antimicrobial technology. Natural fiber and yarn are loaded with natural mineral antimicrobial elements to achieve antimicrobial targets, which belongs to fiber pretreatment technology.

Natural fiber itself has the advantages of softness, comfort, durability, air permeability, purity, etc., cotton and other natural yarn processed by IR microelement technology, the fiber is more soft and comfortable, cotton products are not easy to stiffen.

The principle of sterilization is free sterilization. When encountered with bacteria, it can effectively release sterilization, destroy the cell membrane, cell wall and nucleus of bacteria, and completely kill bacteria.

Based on this technology, Huafang Co., Ltd. developed a cotton antibacterial product with high water resistance.

Antimicrobial fabrics with IR microelements permeate antibacterial active components into cellulose molecules through fiber modification, and then combine antibacterial components closely into cellulose molecules through technical methods, so that fabrics have excellent and lasting antibacterial properties.

Other Antibacterial Techniques

Nowadays, more and more research and production enterprises join in the research and development of antibacterial fibers and textiles, they develop a variety of new antibacterial technologies, and continue to meet the needs of consumers for antibacterial and bacteriostatic.

Crop fiber, jointly developed by Tianan Group and Institute of Microbiology, Chinese Academy of Sciences, is a pure bio-based antibacterial fiber based on PHBV.

It is made of corn starch glucose as the main raw material, through a large number of microbe culture, and the extraction of microbe in the body of a polyester (similar to mammalian fat) - PHBV, and then through the melt spinning system of the new fiber.

The antibacterial mechanism is that after contact with bacteria, the cell wall of harmful bacteria is destroyed to inhibit bacterial breeding, so as to truly achieve the effect of antibacterial and deodorant.

The antibacterial effect of the fiber is long-lasting, does not decrease significantly with the increase of use, and can resist the "superbacterium" - methicillin-resistant Staphylococcus aureus.

Tangshan Sanyou Group Xingda Chemical Fiber Co., Ltd. developed Sanyou Kangli antimicrobial viscose fiber, Sanyou Kangli adopts the physical antimicrobial mode, the active ingredients can contact with the bacterial outer membrane molecules, causing bacterial cell membrane damage, so that the bacterial cytoplasm outflow "disintegration", so as to kill bacteria.

No metal ions, effectively reduce the accumulation of metal ions in the body, antibacterial active ingredients after TD, SDS/MSDS, TDS test, safe and harmless to human body.

The inhibition rate of fiber to Nilococcus albicans reached 96%, Escherichia coli 98% and Staphylococcus aureus 99%.

Products to meet the ring spinning, vortex spinning and other different spinning requirements.

Since the outbreak, the proprietary technology of "reactive oxygen capsules" developed by New River Holdings in Hong Kong has been used in face masks and textiles to effectively prevent the spread of bacteria and viruses.

This capability will open up some new application areas for the product, in particular the market for antiviral textiles, antiviral masks and medical textiles.

According to the new river holding market director introduction, many experimental tests show that the use of "reactive oxygen capsule" technology processing textile has obvious killing effect on a variety of viruses, whether it is to the virus or not enveloped virus.

"Reactive Oxygen Capsules" technology is a slow release technology of strong oxidants, which can slowly release reactive oxygen with high oxidation capacity in the natural environment.

The technology can implant the antiviral function into the textile fabric fiber, bringing the lasting effect of inhibiting and killing the virus, and has the characteristics of washing resistance.

Because the use of this product does not need any adhesive, so basically does not affect the comfort and softness of the fabric, not only suitable for medical protection field, but also suitable for fashion and leisure field.
