Antibacterial textile
Apr 30, 2019
The use of antibacterial textiles is mainly for medical, household and industrial use. It can be used in the medical field to reduce bacterial growth, such as surgical sutures, masks, gloves, etc.; home textiles are prone to aphids and bacteria, and antibacterial textiles have good prospects; antibacterial textiles such as filter cloths and automotive interiors are also beginning to use antibacterials. Technology, such as the use of antibacterial seats and interiors in cars, reduces bacterial growth.
Europe, the United States, Japan and China to evaluate whether textiles are antibacterial, will choose Gram-negative bacteria (such as E. coli) and Gram-positive bacteria (such as Staphylococcus aureus, referred to as Staphylococcus aureus). They are representative and often in contact with life.
In the classification of antibacterial fibers, it can be divided into two major categories, natural and artificial. There are four common types of natural antibacterial fibers:
1. Kapok fiber. It has a large hollow structure closed at both ends, which is not conducive to the survival of anaerobic bacteria. The outer wall contains a natural, bitter substance that will fall off during wear and reduce the antibacterial effect. The test showed that the kapok fiber had obvious antibacterial effect on Escherichia coli, and the effect of dredging was obvious, reaching 87.54%, but it had no obvious effect on Staphylococcus aureus. These fibers are widely used in towels, underwear, sweaters, and bed sheets. It should be noted that the kapok blend fabric does not have an antibacterial effect.
2. Chitosan fiber. This is a fiber made of chitin treated with concentrated alkali. It has good affinity and no toxicity to protein. It has good antibacterial effect on various bacteria and fungi. It is often used in medical dressings, such as hemostatic cotton and gauze. Wait.
3. Hemp fiber. Hemp fibers with antibacterial effects include hemp, flax and apocynum. Hemp fiber contains cannabinoids and is antibacterial; and hemp is a hollow fiber rich in oxygen, making anaerobic bacteria difficult to survive, similar to kapok. Flax fiber has a significant antibacterial effect, and the inhibition rate against Pseudomonas aeruginosa and Candida albicans can reach more than 65%, and the inhibition rate against Escherichia coli and Staphylococcus aureus exceeds 90%. Apocynum venetum has a bacteriostatic rate of 40% to 60% against Staphylococcus aureus and Candida albicans, and has good antibacterial activity. Hemp fiber is widely used, such as clothing, bedding, curtains, sofa cloth, various mats, etc.
4. Bamboo fiber. This is a fiber extracted from naturally grown bamboo. It has a long-lasting and effective natural antibacterial effect. Light and thin products such as mats and sheets can be used.
Artificial antibacterial fiber is an antibacterial agent added to the inside or the surface of the fiber to act as a sterilizing agent during the release process. Mainly divided into three categories: 1 nanometer silver antibacterial fiber. Its antibacterial property relies on the continuous release of nano-silver particles. The fabric using the additive method is resistant to washing and has long-lasting antibacterial effect; the post-processing method is not washable, and the antibacterial property is gradually weakened as the number of washings and the use time increase. It can be applied to daily necessities, including uniforms, casual wear, shirts, underwear, pajamas, bedding and handkerchiefs; for bedding, shirts, socks, underwear, etc. for patients with neurodermatitis; Nano silver antibacterial masks, wet wipes, sanitary napkins, sanitary pads, baby diapers, adult incontinence products, medical sheets, medical dressings, bandages, burns and burns, etc.; in addition, car compartment filter media, garment lining, antibacterial shoulder Pads, bras, antibacterial insoles, shoe materials, blankets, etc.
2 organic antibacterial agent antibacterial fiber. This is an antibacterial fiber obtained by adding a trace amount of an organic antibacterial agent without changing the basic properties of the fiber. It is represented by quaternary ammonium salts and organometallics, and has the advantages of quick and strong sterilization and low price. Such fibers are commonly used in hospital textiles such as clothing, bed sheets, drapes, curtains, pantyhose, socks and bandages.
3 new open fiber. The fiber does not lint, and has better water absorption and softness than conventional cotton fiber, and has excellent antibacterial ability, and is first applied to bath towel products.
