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 antimicrobial properties and fibers coated therewith. More specifically, to provide a composition for coating fibers that is harmless to the human body and exhibits excellent antibacterial and antifungal activity by using a natural extract exhibiting an antibacterial effect. It is to provide a fiber capable of providing excellent antibacterial and antifungal activity at the same time.

In general, fibers are fabrics that are raw materials for all clothes, mats, sofas, and the like, and by using the fibers, clothes to be worn in spring, summer, autumn, and winter, mat covers, sofa covers, and the like are made. However, since most fibers are commercialized through a process such as a simple processing process and sewing that is not provided with functionality, there is a problem in that good conditions are created for the growth of various harmful bacteria and fungi.

Bad odors caused by the propagation of harmful bacteria and fungi not only cause discomfort to the people around them, but also bacteria or molds can multiply on the skin and cause diseases.

In addition, conventionally manufactured fibers are manufactured by mixing a synthetic resin with an organic solvent and the like. Even after being manufactured as a fabric, the organic solvent remains in the fabric and causes skin problems. 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 a fabric into a cover such as clothing, a mat, and a sofa, and the solvent used in the printing composition is a die Methylformamide, toluene, methyl ethyl ketone and ethyl acetate are mainly used, but the solvent not only releases environmental hormones, but can also cause skin problems, and has a problem in that it is released under high temperature conditions and adversely affects the human body. .

In particular, since the fiber is in direct contact with the sweat of the human body, 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 attach to the textile product and cause various diseases. In order to prevent the textile products from being discolored and embrittled by harmful microorganisms or being contaminated from various odors, antibacterial and antifungal deodorization processing is performed to suppress the inhabitation or propagation of microorganisms such as bacteria or mold 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. These antimicrobial fibers refer to those 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 sterilizing, and the antifungal property refers to the property of suppressing the growth of the fungus and eliminating the occurrence of odor by killing the fungus, that is, deodorizing and deodorizing properties.

In addition, as an antibacterial and deodorizing method, a method of applying an inorganic compound such as silver, copper, zinc, silver oxide and zinc oxide or applying an organic compound such as benzyl chloride is commonly known. However, sanitary processing agents made of such an antibacterial compound have a problem in that they cannot be organically adhered to the fibers and durability due to washing.

In addition, in the prior art, 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 still have poor dispersibility due to irregular particle shapes. There is a disadvantage of yellowing when washing durability, in particular, a chlorine-based detergent is used.

However, cationic surfactants in the form of quaternary ammonium salts are used to provide flexibility at the same time as washing or rinsing fibers. As the active agent accumulates on the clothing, a yellowing phenomenon occurs in which the white clothing or fabric turns yellow. In addition, when a fluorescent whitening agent having an anionic charge is used in laundry detergent, the cationic surfactant binds to the optical brightener and reduces the whiteness.

In addition, in the case of using a conventional cationic surfactant, hydrophobic alkyl groups exist on the surface of the fiber to reduce water absorption and impair moisture absorption, and since the base material of the softener is a cation, an anion and an adduct of the detergent component remaining in the washing step It was also found that the problem of lowering the softening effect by forming In addition, since the base material of the fabric softener is insoluble in water, it has been prepared as a fine dispersion of 4 to 6% by mixing a dispersant.

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

Therefore, continuous R&D is required to solve this problem.

Pathogenic E. coli can produce heat-labile enterotoxin (LT), which loses activity when heated at 60 °C for 10 minutes, or heat-stable enterotoxin (ST), which is resistant to heating at 100 °C for 30 minutes. . Among pathogenic E. coli, enterotoxin-type E. coli causes serious problems in animals, and diarrhea in newborn piglets or weaned pigs is a big 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 types.

Among Gram-negative bacteria, Proteus vulgaris, known as food poisoning bacteria, inhabits the intestines of humans and animals, and Staphylococcus aureus is a Gram-positive bacteria that is stored on the skin or nasal surfaces of healthy individuals and produces exotoxins to produce food poisoning. causes In addition, it secretes a toxin that kills phagocytes (leukosidine), hemolysin, and coagulase to break free from the resistance of the infected host cells and cause purulent infection.

Staphylococcus aureus is commonly found on the skin and nasal passages of more than 50% of healthy people and animals, and can cause a variety of diseases, 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 resulting in postoperative wound infections. Staphylococcus aureus can secrete various toxins depending on the strain, which is classified into three categories: pyrogenic toxin superantigens, exfoliative toxins, and other toxins.

The strains that produce seven enterotoxins that cause food poisoning belong to the pyrogenic toxin superantigens. Enterotoxin produced by Staphylococcus aureus causes gastroenteritis, and causes nausea, vomiting, diarrhea, and abdominal pain, and the symptoms are relieved within 8 to 24 hours and heal naturally. Food poisoning symptoms are not caused by bacteria themselves, but by enterotoxin, and since it has strong heat resistance and is not destroyed even by heating and cooking, it is best not to consume food contaminated with Staphylococcus aureus.
