Description

Multi-Functional Fiber Containing Natural Magma-Stone Powder and A Manufacturing Process for the Same}

The present invention relates to a multifunctional fiber containing a natural mineral ore powder, in detail, multi-functional including natural ore and synthetic fiber resins having an effect such as anion and far-infrared emission, water quality improvement, waste decomposition, odor removal, etc. It relates to a fiber and a manufacturing method thereof.

Ore is a kind of igneous rock found only in a specific area that has been the center of the earth's crustal change. It is composed of silicon oxide and aluminum oxide, and various other minerals as shown in Table 1 below.

Chemical composition Content (wt%) SiO ₂ 82.25 Al ₂ O ₃ 8.59 Fe ₂ O ₃ 1.06 TiO ₂ 0.33 CaO 1.55 MgO 0.37 K ₂ O 2.96 Na ₂ O 2.26 MnO 0.02 loss 0.61 Total 100.00

As shown in FIG. 3, the natural light analysis contains fine minerals as a structurally porous material. The porous light absorbs and decomposes harmful substances as well as promotes deodorization. In addition, the minerals contained are eluted by water, which is effective in the growth of plants and organisms. In addition, the mineral ore can emit a large amount of anions at various temperature conditions compared to natural stone or other artificial ceramics, and has a high peak of far-infrared radiation, and there is almost no change in far-infrared radiation at room temperature. Anion emissivity is also high. In particular, it is easy to be absorbed by living organisms and water, and has a high far-infrared emissivity of 4-14 μm, which promotes physiological activity and growth of humans, and thus can be used for various purposes such as activation of water, animal and plant cells, and decomposition of odors. In addition, it has excellent antibacterial effect, deodorizing effect on various odors such as ammonia, and chemical resistance against strong acid and strong alkali.

We are surrounded by far-infrared rays of various wavelengths in our daily lives. But far-infrared radiation is emitted only a very small amount from all objects around us (objects with surface temperature). The scientific pursuit of "an object that efficiently radiates far-infrared rays at specific wavelengths effective for human life at room temperature" has proved that a particular ceramic is such an object. In human life, clinical experiments show that far infrared rays with a wavelength of 7 to 14 µm have a good effect on the human body's biological rhythms, and resonate water molecules, which account for more than 70% of the human body, to activate cells and help blood circulation. The public's interest in far-infrared rays has been increasing since the results were shown to be beneficial to the human body, such as helping to recover from fatigue such as muscles with sufficient supply of dissolved oxygen contained in the product. It is getting bigger.

On the other hand, anions increase the ionization rate of minerals in the blood, unlike cations, which cause excess serotonin and histamine to secrete in the human body, impairing health and lowering the oxygen breathing ability of lungs. By purifying and purifying the blood and promoting the exchange of electrical substances in the cell membrane. Increasing the amount of globulin is known to increase refraction and activate autonomic nervous system blood and lymphatic fluid. In order to obtain such an effect, anion generating device for purifying the air by generating anion electrically has been developed for automobiles, indoors and buildings.

However, in May 1998, the Korean Ginseng and Tobacco Research Institute published a study showing that the method of generating anion electrically increases carbon monoxide concentration in a confined space and ozone generation adversely affects the bronchus of the human body.

Natural sources of negative ions include waterfalls, pine forests, and near beaches where rocks are hit by rocks. In these sources, about 3,000 to 4,000 ions / cc of negative ions are known to exist in the atmosphere.

In recent years, a fiber that generates anions by containing an anion generator during fiber production has been developed, but in most cases, the number of generated anions is less than 200 / cc. However, it is known that the amount of negative ions generated by Kanebo, Gurarei, TOMUS, TAKO and BOFARICH in foreign countries is more than 500 / cc, and the anion sources used by these manufacturers are mainly tourmaline or rare earths. When applied as an elemental powder, they have piezo electric porperty that exhibits electrical properties or generate a small amount of radiation to generate negative ions.

In addition, as shown in <Table 2>, various bacteria inhabit the surrounding environment used by humans, and it is natural to control such bacteria. As the world's population gradually increases, the amount of sunshine decreases due to the rise of buildings and the increase in the time spent in underground spaces, which are threatened by germs and viruses. In particular, since the fiber is mostly used for clothing, it provides a favorable environment for the incubation of microorganisms such as bacteria by sweat, waste and external contaminants secreted by the human body. And infection causing disease. In particular, various microorganisms inhabiting fibers not only damage the fibers, but also cause fatal diseases. Furthermore, as living standards improve, the preference for natural fibers such as cotton or wool over synthetic fibers and the collective housing phenomenon such as high-rise apartments not only facilitate the growth of bacteria, but the damage is more severe during the rainy season and winter. In particular, the elderly, infants and the sick are very likely to be infected from bacteria. Therefore, attempts to impart such a composite function to textile materials have been studied for a long time.

Meanwhile, today, "Fine Ceramics", which selects a functional ingredient, is continuously being developed, and these far-infrared rays and anions-releasing materials have been applied to various fields such as construction, textile, industrial, and food for heating.

Republic of Korea Patent Application No. 1998-7433 relates to a method for producing a multi-functional polyester fiber having a mixed antimicrobial deodorizing function by melting and spinning elvan fine particles and polyester that emits far infrared rays. The experimental results for are not mentioned.

As a method for imparting antimicrobial properties to fibers, Japanese Patent Application Laid-Open No. 59-134418 and Japanese Patent Laid-Open No. 61-17567 provide a method of spraying a liquid containing a metal oxide or zirconia chemically bonded to an odor component in a polyester fiber. The method of coating and the method of dispersing inorganic zeolite in which the inorganic particles are substituted with antibacterial metal by the masterbatch method are known in the fiber, but they are not suitable for garment products requiring laundry durability and dispersibility of metal particles. Not only is it difficult to control, but metal ions react with the polymer, causing color defects.

In addition, Japanese Patent Application Laid-Open No. 54-38951 discloses a method of preparing an ion-exchange copolymer and treating it with an aqueous solution of copper salt or silver salt to provide antimicrobial properties by expressing metal ions on the fiber surface. In addition to the poor physical properties by reacting with the workability is poor in the post-process, such as textile manufacturing process and dyeing.

Accordingly, an object of the present invention is to provide a multifunctional fiber using a photonic fossil powder that exists naturally and emits large amounts of anions and far infrared rays.

Another object of the present invention is to provide a method for producing such a multifunctional fiber.
