Description

Composition for coating fibers with excellent antibacterial properties and fibers coated therewith

The present invention relates to a composition for coating fibers having excellent antibacterial properties and fibers coated therewith. More specifically, by using a natural extract exhibiting an antibacterial effect, to provide a composition for coating fibers that is harmless to the human body and exhibits excellent antibacterial and antifungal activity, using the composition for coating fibers, the flexibility of the fiber itself It is to provide a fiber that can implement excellent antibacterial and antifungal activity while imparting.

In general, fibers are fabrics that are raw materials for all clothes, mats, and sofas, and clothes worn in spring, summer, fall, and winter, mat covers, and sofa covers are made using the fibers. However, since most of the fibers are commercialized through simple processing processes and sewing processes to which no functionality is imparted, there is a problem in creating favorable conditions for the growth of various harmful bacteria or molds.

Odors caused by the propagation of harmful bacteria and fungi not only cause discomfort to people around them, but also cause bacteria or fungi to proliferate on the skin, causing disease.

In addition, conventionally manufactured fibers are produced by mixing synthetic resins with organic solvents and the like to produce fabrics. Even after fabrication, the organic solvents remain in the fabrics and cause skin trouble. In addition, conventionally, a printing composition in which acrylic, solvent, and pigment are mixed is used to print various logos in the process of forming fabric into covers such as clothing, mats, and sofas. The solvent used in the printing composition is a die. Methylformamide, toluene, methyl ethyl ketone, and ethyl acetate are mainly used. These solvents not only release endocrine disruptors, but also cause skin troubles, and are released under high temperature conditions to adversely affect the human body. .

In particular, since the fiber is in direct contact with human sweat, it may cause an unpleasant odor problem due to the generation of a large amount of ammonia, and microorganisms harmful to the human body may be attached to the fiber product and cause various diseases. In this way, in order to prevent textile products from being discolored and brittle from harmful microorganisms or being contaminated from various odors, antibacterial and antifungal deodorization processing is performed to inhibit microorganisms such as bacteria and fungi from inhabiting or propagating in textile products. .

On the other hand, antibacterial fibers are variously applied in the medical field, such as surgical clothes, patient clothes, masks, and bandages, and function as an element of personal protective equipment that protects the wearer from infection. Such antimicrobial fibers refer to fibers treated with an antimicrobial agent to prevent cross-contamination, such as patient-to-patient, patient-to-surface and surface-to-surface.

At this time, the antibacterial property refers to the property of inhibiting the growth of bacteria and sterilization, and the antifungal property refers to the property of suppressing the growth of mold and killing the mold to eliminate the generation of odor, that is, deodorization and deodorization.

In addition, methods of applying inorganic compounds such as silver, copper, zinc, silver oxide and zinc oxide or applying organic compounds such as benzyl chloride are known as antibacterial and deodorizing processing methods. However, sanitary processing agents made of such antibacterial compounds have problems in organic adhesion to fibers and durability in washing.

In addition, in the known technology, in addition to zirconium phosphate used to impart antibacterial properties, organic silicon quaternary ammonium salts, activated alumina, activated carbon, etc. have been widely used until recently, but these antibacterial agents are still irregular in particle shape. There is a disadvantage in washing durability, especially yellowing when using a chlorine-based detergent.

However, cationic surfactants in the form of quaternary ammonium salts are used to impart flexibility to textiles simultaneously with washing or rinsing. As the activator accumulates on clothing, a yellowing phenomenon occurs in which white clothing or fabrics turn yellow. In addition, when an optical brightener having an anionic charge is used in laundry detergent, the cationic surfactant binds to the optical brightener to reduce whiteness.

In addition, when conventional cationic surfactants are used, hydrophobic alkyl groups are present on the surface of fibers to reduce absorbency, thereby impairing sweat absorption. In addition, since the base of the softener is a cation, anions and adducts of detergent components remaining in the washing step are used. A problem of reducing the softening effect by forming a was also found. In addition, since the substrate of the fabric softener is insoluble in water, a dispersant has been blended to form a fine dispersion of 4 to 6%.

Therefore, due to concerns about the risk of chemical components and demand for natural materials, fabric softeners replacing cationic surfactants, which are the main components of fabric softeners, with organic acids and vinegar are gaining popularity in the market.

Therefore, there is a need for continuous research and development to solve this problem.

There is no skin irritation due to use, and excellent antibacterial and antifungal effects can be exhibited.

The composition is a bacteria selected from the group consisting of Escherichia coli, Proteus vulgaris, Staphylococcus aureus, Staphylococcus epidermidis, Klebsiella pneumoniae and a mixture thereof It shows antibacterial activity against.

Escherichia coli is an enteric bacillus belonging to bacillus and belongs to gram-negative bacteria. Most E. coli are resident bacteria and are not pathogenic, but E. coli O157:H7 or enterotoxigenic E. coli (ETEC) are pathogenic. As Escherichia coli, it causes food poisoning in humans and diarrhea in various animals such as cows, pigs, and goats. Pathogenic Escherichia coli can produce heat-labile enterotoxin (LT), which loses activity when heated at 60°C for 10 minutes, or heat-stable enterotoxin (ST), which exhibits resistance even when heated at 100°C for 30 minutes. . Among the pathogenic Escherichia coli, enterotoxin-type Escherichia coli causes serious problems in animals, and diarrhea in newborn piglets or weaned piglets is a major problem in the livestock industry. Among them, K88-type E. coli, K99-type E. coli, 987P-type E. coli, and F41-type E. coli are known as major enterotoxin-type pathogenic E. coli.

Among Gram-negative bacteria, Proteus vulgaris, known as food poisoning bacteria, lives in the intestines of humans and animals, and Staphylococcus aureus is a Gram-positive bacteria that is carried on the skin or nasal surface of healthy individuals and causes food poisoning by producing exotoxins. causes In addition, it secretes toxins (leucocidin) that kill phagocytes, hemolysin, coagulation enzymes, etc., thereby escaping the resistance of infected host cells and causing pyogenic infections.

Staphylococci are commonly found on the skin and nasal cavities of more than 50% of healthy humans and animals, and can cause a variety of diseases ranging from mild skin infections such as acne and impetigo to life-threatening diseases such as pneumonia, meningitis and sepsis. It is also one of the five most common causes of nosocomial infections, often leading to postoperative wound infections. Staphylococcus aureus can secrete various toxins depending on the strain, which are classified into three types: pyrogenic toxin superantigens, exfoliative toxins, and other toxins.

The strains that produce the 7 enterotoxins that cause food poisoning belong to superantigens of febrile toxins. Enterotoxin produced by Staphylococcus aureus causes gastroenteritis, which causes symptoms of nausea, vomiting, diarrhea, and abdominal pain, and the symptoms are relieved and healed naturally within 8 to 24 hours. Food poisoning symptoms are caused by enterotoxins, not by the bacteria themselves, and because they are heat resistant, they are not destroyed even when heated or cooked, so it is best not to consume foods contaminated with Staphylococcus aureus.

In particular, interest and concern about diseases and skin infections caused by microorganisms such as Staphylococcus aureus and Klebsiella pneumoniae, which can rapidly proliferate in clothing and other fabrics that are used and encountered every day, are increasing day by day. It is rising.

Tea tree (Melaleuca alternifolia) is an evergreen tree belonging to the myrtle family and grows in swampy areas. Tea tree is often distilled and used in the form of oil, and it has been proven to have antibacterial and antifungal properties. Due to its antibacterial and antifungal properties, it is also used in various forms of drugs or cosmetics, such as wound disinfectants, acne sedatives, athlete's foot treatments, and respiratory disease treatments. However, there is a problem that it is difficult to use the undiluted solution due to its strong stimulation.

Palm oil is a vegetable oil obtained by steaming and pressing the flesh of an oil palm fruit, and is the world's most productive oil resource, and about 55 million tons are produced and consumed annually. Palm oil is a vegetable oil, but since it is composed of saturated fatty acids and unsaturated fatty acids in a ratio of about 1:1, it maintains a semi-solid form at room temperature. There are research results that reduce serum triglycerides and increase HDL cholesterol.

Coconut oil (coconut oil) is oil squeezed from the flesh or seeds of coconut, and the medium-chain fatty acid 'lauric acid' in coconut oil has antibacterial properties that protect against harmful harmful bacteria.

Olive oil is vegetable oil obtained from olive fruits, and is mainly used in cooking in regions facing the Mediterranean Sea. In addition to its use, it is also used as a raw material for cosmetics, medicines, and soaps, and has not only a unique scent but also a stimulating aroma.

Soybean oil is the oil extracted from soybeans, also called soybean oil or tallow. Conventionally, it has been recognized as one of the groups of cooking oils used only for cooking, but recently it is also widely used as a fuel for transportation. So, the fundamental reason why soybean oil is needed for transportation is to reduce the problem of the vast spread of air pollutants, environmental factors, and harmful environments. It has the advantage of being able to replace diesel. In particular, it is widely used in soaps and body oils for its effect of relieving skin irritation and preventing skin from drying out, and it contains a lot of vitamin E and many amino acids next to upper point oil, so it can show an anti-aging effect.
