3 kinds of antibacterial fibers for textile industry

What are the antibacterial fibers??Antibacterial fiber characteristics, antibacterial fiber performance; antibacterial fiber (silver fiber, copper fiber, photocatalyst fiber, etc.) can be widely used in clothing, home textile products, underwear, sweatshirts, clothing for the elderly, pregnant women and infants. Used in hospital textiles such as clothes, sheets, drapes, curtains and bandages. Textiles made of this fiber have good antibacterial properties and can resist the adhesion of bacteria on clothing, thereby keeping people away from the invasion of germs. At present, the antibacterial fibers that are quite popular in the world are silver-based antibacterial fibers and copper-based antibacterial fibers.

Silver?antibacterial?fiber

It is a high-tech product obtained by permanently combining a layer of silver on the surface of the fiber through special technology. This structure makes the silver fiber maintain the original textile properties and has functions: anti-electromagnetic radiation, antibacterial and deodorizing, eliminating static electricity, etc.

Silver has the effect of regulating body temperature, sterilizing and deodorizing. It is warm in winter and cool in summer. It can be worn next to the skin, directly washed with water, sterilizing and deodorizing, light and soft, breathable, washable, and has excellent shielding properties. It can be used in a wide range of fields. Widely used in: maternity clothing, health clothing, sportswear, medical surgical clothing, shielding clothing silver fiber special fabrics, equipment for special forces, etc.

Strong antibacterial: The mechanism of metal silver sterilization is to block the physiological process of bacteria. In a warm and humid environment, silver ions have very high biological activity - which means that silver ions are easily combined with other substances, causing the proteins inside and outside the bacterial cell membrane to coagulate, thereby blocking the respiration and reproduction of bacterial cells. The warmer and more humid the environment, the stronger the activity of silver ions.

All natural: Silver fiber is made of "pure silver", which is a natural element formed in nature, and has no toxic side effects of general chemical products.

?

Antistatic: Due to the high conductivity of silver, anti-static electricity of 5000v, and electromagnetic shielding function, as long as a small amount of silver fiber exists on the clothing, it will quickly eliminate the static electricity generated by friction, making the product comfortable without static electricity, so silver fiber It can conduct electricity very quickly and efficiently.

?

Extended information: Development of silver fiber: The initial silver fiber production technology is based on nylon 6, and the chemical silver plating technology is used to form a layer of silver coating on the surface of nylon fiber. With the development of science and technology, silver fiber has developed from the initial chemical silver plating method to nanotechnology as the underlying technology, and the silver fiber production technology combining chemical and physical methods is used to produce fabrics that are nano-silver fiber fabrics.

Copper?antibacterial?fiber

Also known as copper ion fiber, it is an antibacterial fiber made by grafting organic copper chains and highly hydrophilic groups on the macromolecular side chains using graft copolymerization technology in the stage of puree polymerization, and then wet spinning technology. Copper ion fiber not only has strong and long-lasting antibacterial, deodorizing, and self-cleaning functions, but also has good hydrophilicity and fabric comfort (fiber moisture regain > 8%). In the testing of professional institutions, the sterilizing rate of copper ion fiber to Staphylococcus aureus, Candida albicans and Escherichia coli is about 99%, reaching the AAA high standard of the national textile industry; in practical applications, only 5% of copper ions are contained After 50 times of repeated washing, the antibacterial rate of the fiber blended yarn still reaches the AAA level with the highest antibacterial rate; the deodorization rate of the fabric containing 5% copper ion fibers to ammonia, acetic acid, isovaleric acid, etc. is over 95%.

Copper ion fibers are widely used in underwear, socks, towels, sportswear, bedding, etc., and have certain potential in the medical field.

The above three inorganic antibacterial and bactericides have the advantages of persistent antibacterial, broad-spectrum, and high safety, so their application fields continue to expand. Metal ion antibacterial agents are an important class of inorganic antibacterial agents. The antibacterial ability of silver ions is far stronger than that of other antibacterial metal ions. Therefore, silver-based inorganic antibacterial agents are more and more widely used in antibacterial textiles.

Graphene antibacterial?Fiber

Graphene is a two-dimensional crystal that is exfoliated from graphite material and composed of carbon atoms with only one layer of atomic thickness. Graphene is currently the thinnest and strongest material in nature, 200 times stronger than steel; at the same time, it has good elasticity, and its stretching range can reach 20% of its own size. As a new type of nanomaterial with the thinnest, highest strength, and strongest electrical and thermal conductivity found so far.

?

Graphene antibacterial fiber is made by attaching graphene to other fibers physically and chemically, or adding graphene to man-made fiber solution to weave. Graphene is a new material in which carbon atoms connected by sp2 hybridization are closely packed into a single-layer two-dimensional honeycomb lattice structure, just like a two-dimensional sheet, a small inorganic blade composed of tiny C elements, the main The antibacterial mechanism has

Graphene inner heating fiber is a new intelligent multi-functional fiber material composed of biomass graphene and various fibers. It has low-temperature and far-infrared functions that exceed the international advanced level. It integrates antibacterial and antibacterial, anti-ultraviolet, anti-static, etc. Acting on one body, it is known as "epoch-making revolutionary fiber". Graphene inner heating fiber filaments and staple fibers have complete specifications. The staple fibers can be blended with natural fibers such as cotton, wool, silk and linen, and other fibers such as polyester and acrylic. The filaments can be interwoven with various fibers to prepare yarns with different functional requirements. fabric. In the textile field, it can be made into underwear, underwear, hosiery, baby clothing, home fabrics, outdoor clothing, etc. The use of graphene inner heating fibers is not limited to the field of clothing, but can also be applied to vehicle interiors, beauty and medical health materials, friction materials, filter materials, etc.

The functionality of graphene fabrics

Low-temperature far-infrared performance: The inner heating fiber compounded with biomass graphene strengthens the inherent hygroscopicity and air permeability of viscose fiber, and the fabric is smooth and soft, smooth to the touch, and not easy to fade; at the same time, it embodies the performance of The most obvious effect of biomass graphene is to enhance the far-infrared effect of body temperature, that is, at a low temperature of 20-35°C, the absorption rate of (6-14) μm wavelength far-infrared light reaches more than 88%. The powerful body temperature far-infrared function of the inner warming fiber fabric helps to accelerate the surface temperature of the skin, expand the capillaries, improve the microcirculation of the body, strengthen the metabolism between various tissues, dredge the meridians, improve immunity, and achieve the health care effect on the human body.

Antibacterial and antibacterial properties: All kinds of bacteria adhere to graphene cotton silk fabrics, graphene cuts cell membranes through sharp boundaries, and then superoxide ions mediate oxidative stress, eventually leading to bacterial death. At the same time, graphene not only destroys the bacterial cell membrane through contact cutting, but also directly extracts the phospholipid molecules on the cell membrane on a large scale to destroy the cell membrane and kill bacteria. Graphene exhibits excellent antibacterial properties when interacting with bacteria, but only weak cytotoxicity when interacting with cells or organisms, indicating that graphene is a nanomaterial with both antibacterial properties and good biocompatibility. It has good application potential in biomedical textiles.

?

Anti-static and anti-electromagnetic properties: The conductivity of graphene is 1×10? S/m, which is a good conductive material. Graphene has a high electron mobility, and the electron mobility in the graphene plane can reach 1.5×10? cm/ (V s), which is 100 times higher than the electron mobility of the current best silicon material. Therefore, adding graphene to the inside of the fiber will improve the antistatic performance of the fiber material. The addition of graphene can reduce the surface resistivity of the fiber, quickly leak the generated static charge, and at the same time endow the material with a certain degree of lubricity and reduce the friction factor, thereby inhibiting and reducing the generation of static charge.

Anti-washing, moisture absorption and moisture conduction properties: Graphene is a two-dimensional periodic honeycomb lattice structure composed of carbon six-membered rings, which can be warped into zero-dimensional fullerenes, rolled into one-dimensional carbon nanotubes or stacked into Three-dimensional graphite. Because of its two-dimensional space, it has a particularly strong water absorption capacity. At the same time, the strong effect is achieved by adding biomass graphene to the masterbatch, so it can be worn for a long time and washed many times, and the performance will not attenuate.

Difference between these 3 antibacterial fiber

Copper fiber is a polyester fiber with special antibacterial and sterilizing functions developed by using natural antibacterial copper materials through high-tech processing and unique production technology. Copper fiber raw materials are mixed with other raw materials, and its hairiness is less , The fabric feels very good, and its flat surface has obvious antibacterial and antibacterial effects, which is more suitable for underwear and medical materials.
