Description

Manufacturing method of UV-blocking fabric and fabric manufactured thereby

The present invention relates to a method of manufacturing a UV-blocking fabric and a fabric manufactured thereby, and more particularly, by manufacturing a fabric including a UV-blocking material, the UV-blocking effect is excellent, and the physical properties of the textile fabric itself are maintained and excellent at the same time. It relates to a method for manufacturing a UV-blocking fabric exhibiting antibacterial and anti-odor activity, and to a fabric manufactured by the same.

Solar rays are composed of gamma rays, X-rays, ultraviolet rays, visible rays, infrared rays, and radio waves of different wavelengths. Among them, ultraviolet rays are electromagnetic waves with a wavelength in the range of 100 to 400 nm. Most of these short wavelength ultraviolet rays are absorbed by the ozone layer in the atmosphere. However, as the ozone layer has recently been seriously destroyed, the amount of UV radiation has increased, and thus, damage to the skin caused by UV rays is becoming a problem.

UV-rays are divided into UV-A (320-400 nm), UV-B (280-320 nm), and UV-C (100-290 nm) depending on the length of the wavelength, and UV-A is again UV-A I (340 nm). ~400nm) and UV-A Ⅱ(320~340nm), of which UV-C is absorbed and scattered by ozone layer, water vapor, dust, etc. UV-A and UV-B are usually blocked.

Erythema, which turns the skin red several hours after exposure to UV rays, occurs, and if exposed to a large amount of UV light, it may progress further and cause burns such as blisters. These phenomena are mainly caused by UV-B UV rays. .

Unlike UV-B, which burns directly on the skin as described above and can be felt immediately, UV-A penetrates deep into the skin and gradually creates spots and freckles to damage the skin, damage the immune system, premature aging of skin cells, and skin cancer. It is also deeply related, and countermeasures are required to be prepared.

Recently, due to the destruction of the ozone layer due to air pollution and the increase in leisure activities, the human body is more exposed to the danger of ultraviolet rays, and accordingly, a method to protect the human body from ultraviolet rays is required. Materials have been developed and applied to materials such as clothing.

The hwangchil leaf extract is prepared by extracting from the leaves of the hwangchil tree, and the hwangchil tree (Dendropanax morbifera Lev) is an evergreen broad-leaved arboreous tree of the genus Araliaceae and native to Korea that grows up to 15 m or more in height. Young twigs are green and glossy, flowers bloom in June, and 7-19mm long fruits ripen in black. It is a temperate plant that grows in areas where the minimum temperature is -2℃ or higher and the annual average temperature is 12~15℃ or higher.

Hwangchil tree secretes hwangchil, which is generally composed of 66.7% of non-volatile components, 10.8% of aromatic components, 8.1% of moisture, and 14.4% of solids, which are paint components that form a golden coating film. It is known that the quiterpenes are composed of β-cubebene, γ-selinene, δ-cadinene, and the like. The aromatic ingredients contained in Hwangchil have various pharmacological effects as well as their value as a benzoic incense that makes the mind and body clear and comfortable.

As the hwangchil tree leaf extract, the hwangchil tree leaf extract prepared by the following preparation method may be used.

First, in order to prepare a hwangchil tree leaf extract, it can be washed after preparing the hwangchil tree leaves.

Next, the washed hwangchil leaves can be pulverized to a certain particle size.

In the above step, by pulverizing the hwangchil tree leaves to a certain particle size, the active ingredient of the hwangchil tree leaves can be sufficiently extracted. . When the particle diameter of the hwangchil leaves is pulverized to less than 500 μm in the above step, it takes a long time to pulverize, and the particles are too small to cause agglomeration between the particles in a later process, and when pulverized in excess of 2500 μm There may be a problem that it is difficult to effectively extract useful ingredients from the leaves of the hwangchil tree.

Next, by removing the solid content after applying ultrasonic waves to the pulverized hwangchil tree leaves in an atmosphere of low temperature and reduced pressure, it is possible to obtain a hwangchil tree leaf extract.

In the above step, after preparing a mixture by mixing the pulverized hwangchil leaves with a solvent, it is put into an ultrasonic extractor to apply ultrasonic waves to the mixture, and the solids contained in the mixture are sieved through a known sieve such as a sieve. It is possible to prepare a hwangchil tree leaf extract by removing using Any one or more solvents selected from (C1 to C4) alcohols may be used.

In addition, in the step, the ultrasonic waves applied to the mixed solution at a temperature of 20 to 25° C. and ^{a pressure of 0.1 to 0.5 kgf/cm 2} are 100 to 200 watts (watt) output at a vibration frequency of 30 to 50 KHz for 30 to 60 minutes By extracting using a hwangchil tree leaf extract can be obtained.

The solvent may be used to improve workability and adhesion by controlling the viscosity and fluidity when applying the antimicrobial coating solution to the fiber yarn, and the solvent includes an ether solvent, an acetate solvent, an alcohol solvent, or a mixture thereof. Solvents may be used.

For example, as the ether solvent, propylene glycol monopropyl ether, propylene glycol monomethyl ether, ethylene glycol monoethyl ether, ethylene glycol monopropyl ether, ethylene glycol monobutyl ether, diethylene glycol monomethyl ether, diethyl Glycol monoethyl ether, diethyl glycol monopropyl ether, diethyl glycol monobutyl ether, diethylene glycol-2-ethylhexyl ether, etc. can be used alone or in combination.

As the acetate-based solvent, butyl acetate, ethyl acetate, etc. may be used alone or in combination.

As the alcohol-based solvent, diacetone alcohol (DAA), n-butanol, methanol, ethanol, isopropyl alcohol, and the like may be used alone or in combination.
