Yarn is a generic term for yarn that is used as a raw material for all textile products such as textiles, knitted fabrics, fabrics, and lace. It is divided into fibers and man-made fibers such as rayon and nylon.

Natural fibers are divided into vegetable fibers composed of cellulose, which is a component of plant cell walls, animal fibers obtained from animal hair or secretions, and mineral fibers that are naturally fibrous.

In addition, natural fibers have advantages such as excellent touch to the skin, eco-friendliness, and fast drying, but are weak in durability and wrinkle easily. This makes it difficult to use.

Man-made fibers are divided into inorganic fibers composed of inorganic substances, organic fibers composed of organic substances based on carbon, and synthetic fibers manufactured by processing ingredients extracted from petroleum or coal.

In addition, artificial fibers have the advantage of improving the problems of natural fibers and easy to wash because they do not stain well, but have a disadvantage of severe static electricity.

Recently, due to environmental pollution and infectious diseases, interest in yarns or fibers having antibacterial properties is attracting attention.

The following is a background art on yarns or fibers having antibacterial properties. There are Publication No. 10-1910334 (hereinafter, Document 3) and Patent Registration No. 10-1988537 (hereinafter, Document 4).

Document 1 Invention is a functional composition PP for preparing a spun yarn by mixing a volatile silver nano solution, a pigment, and an anionic mineral powder to prepare a silver nano pigment composition after preparing a volatile silver nano solution, and mixing the silver nano pigment composition with a polypropylene (PP) resin It relates to the production of spun yarn.

Document 2 The present invention relates to a method for producing an antibacterial polyester fiber using silver nanoparticles, and relates to a fiber having antibacterial properties prepared in the form of long and short fibers by dispersing and polymerizing silver oxide in a polyester resin and then melt spinning.

In the inventions of Documents 1 and 2, silver nanoparticles are used to impart antibacterial properties to spun yarns or fibers, but recently, the toxicity problem of silver nanoparticles has been raised due to animal experiments in which silver nanoparticles are toxic to the lungs and liver.

In addition, when the yarn or fiber containing silver nano is washed, there is a problem in that the silver nano component is peeled off from the yarn or fiber, thereby reducing the antibacterial performance.

In the invention of Document 3, a coating agent containing hydrogen anion-containing calcium is applied on a fiber, and the fiber coated with the coating agent is thermocompression-bonded so that hydrogen anion-containing calcium particles are formed by a gap between a yarn of the fiber and a neighboring yarn. It relates to a method for manufacturing an antibacterial fiber through a process of flattening a yarn while allowing it to be embedded.

The antibacterial fiber of the invention of Document 3 is only a coating agent containing calcium containing hydrogen anion, which is an antibacterial agent, applied to the surface of the fiber.

The invention of Document 4 relates to a method for imparting natural antibacterial properties to wool yarns having antibacterial properties by immersing the wool yarns in a natural antibacterial agent to which additives are added.

In the wool yarn of the invention of Document 4, as in the invention of Document 3 described above, the natural antibacterial agent is only applied to the surface of the wool, and antibacterial performance may be reduced due to several washing processes.

In describing the present invention, if it is determined that a detailed description of a related known technology may obscure the gist of the present invention, the detailed description thereof will be omitted.

<Example 1>

As shown in FIG. 1 , the manufacturing method ( S100 ) of a yarn including magnetic mineral particles includes a first step ( S110 ) in which magnetic mineral particles are manufactured, and a second step in which a master batch chip containing magnetic mineral particles is manufactured. Step (S120), a third step (S130) of manufacturing a raw material containing magnetic mineral particles, and a fourth step (S140) of manufacturing a yarn containing magnetic mineral particles may be sequentially performed.

In the first step (S110) in which the magnetic mineral particles are manufactured, the magnetic minerals may be pulverized to produce magnetic mineral particles.

Here, the magnetic mineral includes Fe ₂ O ₃ or Fe ₃ O ₃ as a component, but a mineral having magnetism may be used. Preferably, any one or more magnetic minerals of phyllite, zeolite, elvan, bentonite, perlite, muscovite, phosphite, biotite, sericite, hematite, magnetite, or hematite may be used, but the ruler used according to the function given to the manufactured yarn It is not particularly limited thereto because the star may be changed.

Here, when two or more magnetic minerals are mixed and used, the limit of the particle size at the time of grinding may be different depending on the magnetic mineral used.

Accordingly, two or more magnetic minerals having different particle sizes are not uniformly dispersed in the resin raw material during the manufacture of the masterbatch chip to be described later. It is more preferable that any one of magnetic minerals of , perlite, muscovite, phlogopite, biotite, sericite, hematite, magnetite, or hematite is used.

For example, phyllite is a metamorphic rock with intermediate properties between slate and crystalline schist. It contains a large amount of germanium to activate metabolism, and it emits about three times more far-infrared rays than loess and elvan, helping to improve blood flow. can give

For example, zeolite is a microporous aluminum silicate mineral, has excellent adsorption properties, is excellent in removing impurities and deodorization, and has antibacterial properties.

For example, elvan is a rock belonging to porphyry, has the action of exchanging ions with heavy metals, and when heat is applied, far-infrared rays are emitted, thereby helping to improve blood flow.

For example, bentonite is a mineral belonging to a monoclinic system having a crystal structure like mica.

For example, pearlite is a kind of silicate nitrite and contains countless pores, so it has a small weight to volume ratio and is light, and fine particles are filled in the voids between the particles to prevent convection, thereby providing excellent thermal insulation.

For example, muscovite is a layered silicate mineral containing potassium and aluminum, has an excellent antibacterial effect, is harmless to the human body because it does not contain heavy metals, and has muscovite luster itself, so that a glossy yarn can be manufactured.

For example, phloem mica is mica belonging to a monoclinic system close to biotite, has excellent antibacterial effect and thermal stability, and radiates far-infrared rays to help improve blood flow.

For example, biotite is a dark-colored and shiny mineral, and has about three times higher far-infrared emissivity than loess and elvan, helping to improve blood flow, and has excellent antibacterial and antifungal properties.

For example, sericite belongs to the monoclinic system, contains germanium to help metabolism actively, and far-infrared rays are emitted to help improve blood flow.

For example, Haerokseok is an illite-like earth mineral having a structure similar to that of mica, has a high antibacterial effect against E. coli and Pseudomonas aeruginosa, and emits far-infrared rays to help improve blood flow.

For example, magnetite and hematite are oxide minerals of iron, and far-infrared rays are emitted to help improve blood flow.

Most preferably, the magnetic mineral has far-infrared radiation and antibacterial and antifungal properties, and biotite that can improve blood flow by radiating magnetic waves and far-infrared rays may be used.

The first step (S110) may be performed to manufacture a yarn containing magnetic mineral particles during melt spinning, which will be described later.

In this case, magnetic mineral particles having a particle size of 2 μm or less may be manufactured by a pulverizer, but may vary depending on the diameter of the used spinning nozzle, and thus is not limited thereto.

For example, when the particle size of the magnetic mineral particles is more than 2 μm, the radiation nozzle may be blocked by the magnetic mineral particles. Therefore, in order to prevent clogging of the radiation nozzle as described above, it is preferable that the magnetic mineral particles be manufactured so that the particle size is 0.1 to 1.6 μm.

For example, when the particle size of the magnetic mineral particles is less than 0.1 μm, the limit of the use of the grinder and the cost thereof may increase. Accordingly, it is most preferable to manufacture the magnetic mineral particles to have a particle size of 0.3 to 1.6 μm.

The grinder may be a bead mill, but is not particularly limited thereto.

The bead mill is a wet pulverization type, and magnetic minerals may be pulverized by friction between a slurry and a bead by the rotational force of a stirrer in the chamber.

In the second step (S120) of manufacturing the master batch chip containing the magnetic mineral particles, the magnetic mineral particles prepared in the first step (S110) are mixed and dispersed in the resin raw material (A), magnetic mineral particles A masterbatch chip (hereinafter referred to as a masterbatch chip) containing can be manufactured.

The resin raw material (A) is selected from polypropylene, polyester, nylon, acrylic, polyurethane, polyethylene, or polyethylene terephthalate. Any one or more may be included, but is not particularly limited thereto.

Here, when two or more resin raw materials (A) are mixed and used, the melting point fluctuates depending on the resin raw material (A) used, so that it may be difficult to perform melt spinning during yarn production.

In order to prevent melting point fluctuations and perform melt spinning smoothly as described above, it is preferable that any one resin raw material (A) selected from polypropylene, polyester, nylon, acrylic, polyurethane, polyethylene, or polyethylene terephthalate is used. .

For example, when polypropylene is used as the resin raw material (A), there is an advantage that it is harmless to the human body because environmental hormones are not emitted, and yarns having light weight, water repellency and quick-drying, hygiene and antifouling properties, drainage properties, heat retention, chemical resistance and heat resistance are used. can be manufactured.

For example, when polyester is used as the resin raw material (A), it is possible to mass-produce it, so it has the advantage of low production cost, and it is not possible to make dye transfer and discoloration well, and it is possible to manufacture a yarn having wrinkle resistance.

For example, when nylon is used as the resin material (A), it is possible to mass-produce it, so that the production cost is low, flexibility, strength, and corrosion resistance are excellent, and it is possible to manufacture a yarn having anti-pull resistance.

For example, when acrylic is used as the resin material (A), it has the advantage of low production cost, excellent heat retention and elasticity, and is strong against direct sunlight and chemicals, so it is free to use detergent or bleach, but it is light and soft with a touch similar to wool. yarn can be produced.

For example, when polyurethane is used as the resin material (A), it is possible to manufacture a yarn having excellent elasticity and elasticity, and excellent dyeability, friction and flexural strength.

For example, when polyethylene is used as the resin material (A), it is possible to manufacture a yarn lighter than polypropylene, strong against alkali, and having waterproof properties.

For example, when polyethylene terephthalate is used as the resin raw material (A), a recycled yarn capable of preventing environmental pollution can be manufactured by recycling discarded PET bottles.

More specifically, the masterbatch chip contains 10 to 20% by weight of magnetic mineral particles dispersed in 80 to 90% by weight of the resin raw material (A), and 200 to at a temperature of 110 to 300℃ by a kneader. The twin-screw screw is rotated at a speed of 500 rpm to melt and mix, and the molten mixture is discharged as an injection product, and the injection product is cooled at a temperature of 220° C. or less and then cut to form a chip as shown in FIG. 3 .

For example, when the magnetic mineral particles are out of the range of 10 to 20 wt%, the magnetic mineral particles are agglomerated, and it may be difficult to manufacture a master batch chip in which the magnetic mineral particles are uniformly dispersed.

That is, the masterbatch chip may contain 10 to 20% by weight of magnetic mineral particles.

For example, if it is out of the temperature range of 110 ~ 300 ℃ during melt mixing, the resin raw material (A) may not melt or burn, it may be difficult to mix the magnetic mineral particles in the resin raw material (A).

For example, when polypropylene is used as the resin raw material (A), it may be melted at 210 to 250° C., which is between the melting point and the decomposition temperature.

For example, when polyester is used as the resin raw material (A), it may be melted at 265 ~ 285 ℃ between the melting point and the decomposition temperature.

For example, when nylon is used as the resin material (A), it may be melted in a melting point temperature range of 212 to 255°C.

For example, when acrylic is used as the resin raw material (A), it may be melted in a melting point temperature range of 160 to 210°C.

For example, when polyurethane is used as the resin raw material (A), it may be melted at 180 to 250° C., which is between the melting point and the decomposition temperature.

For example, when polyethylene is used as the resin material (A), it may be melted in a melting point temperature range of 110 to 140°C.

For example, when polyethylene terephthalate is used as the resin raw material (A), it may be melted at 180 to 260° C., which is between the melting point and the decomposition temperature.

For example, when out of the speed range of 200 to 500 rpm during melt mixing, it may be difficult to manufacture a master batch chip in which magnetic mineral particles are uniformly dispersed due to aggregation of magnetic mineral particles.

For example, when the cooling temperature of the injection-molded product exceeds 220° C., the resin raw material (A) may be melted again, making it difficult to manufacture in the form of chips.

For example, when polypropylene is used as the resin raw material (A), it may be cooled in a crystallization temperature range of 110 to 120 °C.

For example, when polyester or polyethylene terephthalate is used as the resin raw material (A), it may be cooled in a crystallization temperature range of 120 to 220 °C.

For example, when nylon is used as the resin material (A), it may be cooled at 75° C. or less where nylon does not melt.

For example, when acrylic or polyurethane is used as the resin raw material (A), it may be cooled at 80° C. or less where the acrylic or polyurethane does not melt.

For example, when polyethylene is used as the resin raw material (A), it may be cooled at 90° C. or less where polyethylene does not melt.

In the third step (S130) of manufacturing the raw material containing the magnetic mineral particles, the resin raw material (A-1) 70 to 83 weight in order to prepare the raw material containing the magnetic mineral particles in 3% by weight or less. % of the masterbatch chip containing 10 to 20% by weight of the magnetic mineral particles may be melted and mixed at a temperature of 110 to 300 ℃ by 7 to 30% by weight.

The resin raw material (A-1) may be the same as the resin raw material (A) described above. Therefore, the melting temperature of the resin stock (A-1) may have the same melting temperature range as that of the resin stock (A).

For example, when polypropylene is used as the resin raw material (A), the same polypropylene as the resin raw material (A) should be used as the resin raw material (A-1).

As another example, when polyester is used as the resin raw material (A), the same polyester as the resin raw material (A) should be used as the resin raw material (A-1).

If the resin raw material (A) and the resin raw material (A-1) use different types of resin, the resin raw material (A-1) and the resin raw material (A) contained in the masterbatch chip may not be mixed. have.

For example, when melting and mixing in the third step (S130), when out of the temperature range of 110 ~ 300 ℃, the resin raw material (A-1) and the masterbatch chip may not melt or burn.

For example, when the resin raw material (A-1) is out of the mixing range of 70 to 83% by weight and the master batch chip 7 to 30% by weight containing 10 to 20% by weight of magnetic mineral particles, the magnetic ore of the manufactured raw material When the amount of the object particles exceeds 3% by weight, the magnetic mineral particles may agglomerate during spinning, and the spinning nozzle may be clogged.

Preferably, 7 to 20% by weight of the master batch chip containing 10 to 20% by weight of magnetic mineral particles is melt-mixed in 80 to 93% by weight of the resin raw material (A-1), so that the magnetic mineral particles are 2% by weight or less A raw material containing can be manufactured.

More preferably, 7 to 10% by weight of the masterbatch chip containing 10 to 20% by weight of magnetic mineral particles is melt-mixed in 90 to 93% by weight of the resin raw material (A-1), so that the magnetic mineral particles are 1% by weight A raw material containing the following may be manufactured.

When the raw material is spun, a yarn containing magnetic mineral particles is produced, and long fibers, short fibers, and cotton (for fillers, needles) containing magnetic mineral particles by using the generated yarn containing magnetic mineral particles For example), nonwoven fabrics, spun yarns, fabrics, etc., various types of textile products can be manufactured.

In the fourth step (S140) of manufacturing the yarn containing the magnetic mineral particles, when the raw material containing the magnetic mineral particles prepared in the third step (S130) is melt-spinning and stretched, the magnetic mineral particles are produced The containing yarn may be manufactured. In this case, of course, in addition to melt spinning, dry spinning or wet spinning is possible.

Here, the melt spinning pushes the raw raw material melted by heat through the spinning nozzle of the melt spinning machine with pressure, so that the yarn in the form of a yarn is manufactured. In this case, the melt spinning may be performed under conditions of a spinning temperature of 110 to 300° C. and a spinning speed of 1,500 to 3,500 mpm.

For example, if the melt spinning temperature is out of the temperature range of 110 ~ 300 ℃, the raw material may not melt or burn and the spinning nozzle may be clogged.

Here, as the raw material includes the resin raw material (A, A-1), it may be melt-spun in the same melting temperature range as the resin raw material (A) described above.

For example, when the melt spinning speed is out of the speed range of 1,500 to 3,500 mpm, it may be manufactured in the form of a broken thread falling in the shape of a water droplet, or the thickness of the yarn may not be spun uniformly.

The spinning nozzle may use a nozzle having a diameter of 2 to 4 μm in order to prevent clogging of the nozzle when raw material containing magnetic mineral particles having a particle size of 2 μm or less is melt-spun, but the magnetic mineral particles Of course, it is not limited thereto because it may vary depending on the size of the particle size.

Here, the stretching is an operation of stretching the yarn produced through the melt spinning to fit the intended use by using a roller. In this case, the stretching may be performed under the condition that the stretching temperature is 100° C. or less, and the stretching ratio is 1.5 to 3 times.

For example, when the stretching temperature exceeds 100° C., it may be melted depending on the resin raw material (A, A-1) contained in the raw material, and thus the yarn may be cut and it may be difficult to manufacture into a long fiber.

For example, when polypropylene is used as the resin material (A, A-1) included in the raw material, stretching may be performed at 60 to 100°C.

For example, when polyester or polyethylene terephthalate is used as the resin raw material (A, A-1) included in the raw material, stretching may be performed at 80 to 100°C.

For example, when nylon is used as the resin material (A, A-1) contained in the raw material, stretching may be performed at 40 to 45°C.

For example, when acrylic or polyurethane is used as the resin raw material (A, A-1) included in the raw material, stretching may be performed at 80 to 100°C.

For example, when polyethylene is used as the resin raw material (A, A-1) included in the raw material, stretching may be performed at 90 to 100°C.

For example, when the draw ratio is performed less than 1.5 times, it is difficult to manufacture high-strength yarn, and when the draw ratio is performed more than 3 times, the strength may be lowered by breaking by the draw tension.

The yarn including the magnetic mineral particles manufactured through the manufacturing method ( S100 ) of the yarn including the magnetic mineral particles may be formed into long fibers as shown in FIGS. 4 and 5 .

When the long fiber uses a weaving machine, a woven or knitted fabric can be manufactured.

In the second step (S120), in the second step (S120), when 3 wt% of magnetic mineral particles are mixed with 70 wt% of the resin raw material (A) , it becomes possible to agglomerate the magnetic mineral particles.

Accordingly, in the present invention, in order to improve the above problems, by manufacturing the raw material through the third step (S130) after manufacturing the master batch chip, the magnetic mineral material does not agglomerate in the resin raw material (A, A-1). Evenly dispersed, it becomes possible to manufacture a yarn in which the magnetic mineral is evenly mixed.

The step of winding the yarn including the magnetic mineral particles generated after the fourth step (S140) on a bobbin may be selectively performed. At this time, the wound yarn has the advantage of convenient storage and movement.

When the twisting step of twisting the yarn including the magnetic mineral particles prepared by the above method or the braiding knitting step is additionally performed, the composite yarn including the magnetic mineral particles can be manufactured.

<Example 2>

Instead of the fourth step (S140) of the first embodiment, step 4-1 (S140-1) may be performed.

Here, the first step (S110), the second step (S120), and the third step (S130) except for the step 4-1 (S140-1) are performed in the same manner as in the above-described embodiment 1, so that the overlapping content is omitted.

In the 4-1 step (S140-1), the raw material containing the magnetic mineral particles is sequentially melt-spinning, cooling, and stretching, so that the yarn containing the magnetic mineral particles can be manufactured.

Since the melt spinning is performed in the same manner as in Example 1 described above, overlapping contents are omitted.

In the cooling, in order to prevent the yarn produced by melt spinning, from being tangled, a yarn whose surface temperature is lowered by using cold air or cooling water may be manufactured.

Here, the cooling of the yarn may be performed in the cold air or cooling water in a temperature range of 50° C. or less, and preferably in a temperature range of 10 to 30° C.

For example, when cold air or cooling water is performed above 50° C., the resin raw materials A and A-1 included in the yarn may be melted and the yarn may be broken.

Since the stretching is performed under the same conditions as in Example 1 described above using a yarn having a lower surface temperature, overlapping details will be omitted.

The step of winding the yarn including the magnetic mineral particles generated after the 4-1 step (S140) on the bobbin may be selectively performed.

The manufacturing method of the yarn including the magnetic mineral particles in which the 4-1 step (S140-1) was performed instead of the fourth step (S140) of the first embodiment may be divided into S100-1.

<Example 3>

In the manufacturing method (S100, S100-1) of the yarn containing the magnetic mineral particles of Example 1 or Example 2, a fifth step (S150) of chemical treatment and drying may be additionally performed.

Except for the fifth step (S150), the first step (S110), the second step (S120), the third step (S130) and the fourth step (S140) are performed in the same manner as in the first embodiment described above, Since step 4-1 (S140-1) is performed in the same manner as in Embodiment 2, overlapping contents are omitted.

After performing the fourth step (S140) or the fourth step (S140-1), a fifth step (S150) of chemical treatment and drying may be performed.

In the fifth step (S150) of chemical treatment and drying, after chemical treatment to prevent static electricity appearing according to the use of resin raw materials (A, A-1), drying is performed for 0.5 to 1.5 hours to prevent static electricity, magnetic minerals A yarn comprising particles can be produced.

After the fifth step (S150), the step of winding the yarn wound around the bobbin may be selectively performed.

At this time, the crimped yarn may be formed in a shape such as wavy, curved, twisted, spiral or coiled in the longitudinal direction.

Thereafter, the crimped yarn is cut to produce short fibers ( S230 ) may be performed.

At this time, the length to be cut is not particularly limited because it may vary depending on the intended use.

For example, out of the temperature range of 100 ~ 120 ℃ of heat setting conditions, or out of the time range of 5 ~ 10 minutes, the productivity of the short fibers may be reduced.

Here, if the short fibers are not cut, a filling material or a bedding material may be manufactured in the form of cotton as in FIG. 7 .

When the short fibers are spun, a spun yarn including magnetic mineral particles can be manufactured.

After the cross-lapping step (S340), the needle punching step (S350) may be performed.

In the step of needle punching ( S350 ), the nonwoven fabric manufactured by cross-lapping is entangled with the part through which the punching needle of the needle punching machine has passed, so that the nonwoven fabric can be firmly manufactured.

<Experimental Example 1>

The far-infrared emissivity and radiant energy of the magnetic mineral used in the present invention were confirmed.

Here, as the magnetic mineral, the powders of phyllite, zeolite, elvan, bentonite, perlite, muscovite, phlegm mica, biotite, sericite, hematite, magnetite, and hematite described in Example 1 were used, respectively.

Far-infrared rays are infrared rays with a wavelength of 25 μm or more, which are longer than visible rays, so they are invisible to the naked eye, and they are well absorbed because of their large thermal action and strong penetrating power.

In addition, far-infrared rays are radiated to the water and protein molecules constituting the cells in the human body and resonate with minute vibrations about 2,000 times per minute to activate cell activity. At this time, it raises body temperature while generating thermal energy in the process of cell activity.

That is, when the body temperature is increased by far-infrared rays, microvessels expand and blood circulation is activated, thereby enhancing metabolism and increasing tissue regeneration, decomposing blood clots in blood vessels and promoting blood circulation.

In this case, the far-infrared radiation energy confirmation method was confirmed in the emissivity (5-20㎛) after setting the application temperature to 40, 50 ℃ based on KICM-FIR-1005.

[Table 1] below shows the results of far-infrared emissivity and radiant energy of magnetic minerals.

magnetic mineral application temperature Emissivity (5~20㎛) Radiant energy (W/m2·㎛) phyllite 40℃ 0.926 3.71×10 ² zeolite 0.928 3.74×10 ² elvan stone 0.926 3.73×10 ² bentonite 0.917 3.7×10 ² perlite 0.917 3.7×10 ² muscovite 0.922 3.72×10 ² gold mica 0.92 3.71×10 ² biotite 0.924 3.73×10 ² sericite 0.916 3.7×10 ² Haerokseok 0.921 3.71×10 ² magnetite 0.924 3.7×10 ² hematite 0.923 3.69×10 ² biotite 50℃ 0.917 4.25×10 ² 0.921 4.28×10 ²

When described with reference to [Table 1] above, zeolite has the best far-infrared emissivity at 0.928 in the wavelength of 5-20㎛, which is far-infrared rays beneficial to human health, and phyllite and elvan are in second place with 0.926, biotite and magnetite. It was confirmed that this was 0.924, which corresponds to the 3rd rank.

In terms of radiation energy, biotite at 50°C is the best at 4.25~4.28×10 ² W/m2·㎛, zeolite at 40°C is in second place at 3.74×10 ² W/m·㎛, and 40°C It was confirmed that the elvan stone and biotite of 3.73×10 ² W/m2·㎛ corresponded to the third order.

In Table 1, it was confirmed that the emissivity of biotite was 0.924 at 40 ° C., and the emissivity was 0.917 to 0.921 at 50 ° C., and when the application temperature was increased, the far-infrared emissivity slightly decreased at a wavelength of 5 to 20 μm.

In addition, in Table 1, biotite has a radiation energy of 3.73×10 ² W/m 2 μm at 40°C, and 4.25-4.28×10 ² W/m 2 μm at 50° C. It was confirmed that the energy was increased.

Through this, it can be seen that the emissivity and radiant energy of far-infrared rays vary depending on the application temperature even for the same mineral. It can be inferred that the emissivity and radiant energy may appear differently depending on the processing state, surface state, temperature, etc. of the same mineral.

<Experimental Example 2>

The far-infrared emissivity and radiant energy of the yarn containing biotite particles prepared in Examples 1-1 to 1-4 were checked.

Here, the far-infrared radiation energy confirmation method of the yarn containing biotite particles is based on KFIA-FI-1005, and each sample was measured against a black body at 37° C. using an infrared spectrophotometer (FT-IR spectrometer). .

In this case, as the sample, the yarn containing biotite particles prepared in Examples 1-1 to 1-4 was used.

[Table 2] below shows the results of far-infrared emissivity and radiant energy of yarns containing biotite particles.

division Emissivity (5~20㎛) Radiant energy (W/m2·㎛) Example 1-1 0.909 3.5×10 ² Example 1-2 Examples 1-3 0.901 3.47×10 ² Examples 1-4

Referring to Table 2 above, Example 1-1 is a polypropylene yarn containing 2% by weight of biotite particles, and Example 1-2 is a polyester yarn containing 2% by weight of biotite particles. As a result, it was confirmed that the far-infrared emissivity of a wavelength of 5 to 20 μm was 0.909, and the radiation energy was 3.5×10 ² W/m 2 ·㎛.

In addition, Examples 1-3 are polypropylene yarns containing 1.5% by weight of biotite particles, Examples 1-4 are polyester yarns containing 1.5% by weight of biotite particles, and far-infrared emissivity of 5 to 20㎛ wavelength is 0.901, and it was confirmed that the radiation energy is 3.47×10 ² W/m 2 ·㎛.

Although the resin raw materials (A, A-1) used in Examples 1-1 and 1-2, and Examples 1-3 and 1-4 are different from each other, the biotite particles are the same as magnetic minerals. It can be seen that the far-infrared radiation emitted from the yarn is related to the biotite particles contained in the yarn.

In addition, when comparing the far-infrared emissivity of the biotite powder measured at 40 and 50° C. of [Table 1] described above and the yarn containing 1.5 to 2 wt% of the biotite particles, the far-infrared emissivity of the biotite powder was 0.924, respectively, 0.917 to 0.921, and it was confirmed that the far-infrared emissivity of the yarn was 0.901 to 0.909.

In addition, when comparing the far-infrared radiation energy of the biotite powder measured at 40 and 50° C. of [Table 1] described above and the yarn containing 1.5 to 2% by weight of the biotite particles, the far-infrared radiation energy of the biotite powder was respectively 3.73 × 10 ² W/m 2 ·㎛, 4.25 ~ 4.28 × 10 ² W / ㎡ ·㎛, it was confirmed that the far-infrared radiation energy of the yarn is 3.47 ~ 3.5 × 10 ² W/m ·㎛.

Through the above comparison results, it was confirmed that the far-infrared emissivity and radiant energy were relatively lowered when biotite particles were mixed in the yarn production rather than the biotite powder alone, but far-infrared radiation was emitted from the yarn containing biotite particles. .

Through the above results, it was confirmed that the far-infrared emissivity and radiant energy values of the prepared yarn containing biotite particles were not significantly different from the far-infrared emissivity and radiant energy values of the biotite powder alone.

Therefore, yarns manufactured using any one magnetic mineral of phyllite, zeolite, elvan, pearlite, muscovite, phosphite, sericite, herelite, magnetite, or hematite having a far-infrared emissivity and radiant energy value other than biotite are magnetic mineral powder. It can be inferred that the far-infrared emissivity and radiant energy values can be similar to those of

16, it was confirmed that the sample (TAS 40) had an antibacterial degree of 99.6% against Staphylococcus aureus and 57.7% of an antibacterial degree against Bacillus pneumoniae.

17 and 18, it was confirmed that the sample (TAS 40) had an arylamine content of less than 5 mg/kg, which satisfies the specifications of the polypropylene nonwoven fabric.

From the above results, it can be inferred that nonwoven fabrics prepared using resin raw materials (A, A-1) other than polypropylene will also show similar results.

<Experimental Example 5>

To confirm the antibacterial activity, Escherichia coli ATCC 25922 was used as a test strain.

23 to 25, it was confirmed that the sample (biotite 100) had an antibacterial activity of 99.9% against E. coli.

That is, from the above results, it can be inferred that the antibacterial activity against E. coli is 99.9% when manufacturing a textile product using a polypropylene yarn containing 2% by weight of biotite particles.

From the above results, it can be inferred that yarns manufactured using resin raw materials (A, A-1) other than polypropylene will also show similar result values.

<Experimental Example 7>

The antibacterial activity of the composite yarn sample (biotite 50) described in the present invention was confirmed.

For the composite yarn sample (biotite 50), a composite yarn prepared by mixing the polypropylene yarn containing 2 wt% of the biotite particles prepared in Example 1-1 and the polypropylene yarn in a 1:1 weight ratio was used.

<Experimental Example 10>

EEG was measured before and after the use of the fabric prepared using the yarn containing biotite particles prepared in Examples 1-1 to 1-4.

30 is a result of measuring the left and right EEG after using the fabric, it was confirmed that the activation of the delta wave, theta wave and alpha wave regions observed before using the fabric was relatively reduced.

That is, through FIGS. 29 and 30, it was visually confirmed that the EEG was stabilized after use rather than before use of the fabric. Various components dissolved in the blood are ionized under the influence of the magnetic field generated by the biotite particles. This is done by electrolyte dissociation, and the increased ions facilitate the blood flow, which facilitates the control of the autonomic nervous system and promotes blood circulation.

Therefore, when the fabric is used as a bedding product such as a quilt, pad, pillow, eye patch, etc., there is an advantage in that it can help the blood circulation of the brain and can take a good sleep, improve insomnia, or is effective for meditation.

Through the above experimental examples, the yarn containing the biotite particles promotes the blood circulation of the user due to the effect of the magnetic field generated from the biotite particles, and it is possible to manufacture a functional textile product having antibacterial and antifungal properties.

Here, the functional textile product can be applied to various industries such as clothing and household use, as well as medical, sanitary, and industrial textiles.

For example, the clothing may include, but is not limited to, underwear, outerwear, underwear, socks, children's clothing, and the like.
