Description

Medical pressure band {MEDICAL PRESSURE BAND}

The present invention relates to a medical compression band with excellent thermal conductivity and contact cold sensitivity. More specifically, it is used as a compression band for the treatment of edema, which applies pressure to treat chronic inflammation of the arms or legs that may be caused by edema. This relates to a medical compression band with improved fit and breathability by providing excellent thermal conductivity and contact cold sensitivity along with good elasticity.

Hereinafter, in the present invention, the term "double covering" refers to manufacturing a single covering yarn by first covering the screening (C) with a primary effect yarn (E1), and then covering the single covering yarn with a secondary effect yarn (E2). This means secondary covering.

A medical compression bandage is used as a compression band to treat edema by applying pressure to chronic inflammation in the arms or legs that may be caused by edema, or is a compression band that is wrapped and fixed after splinting the fractured area during cast treatment for fracture patients. It is used, etc.

Hyaluronic acid is a polymer compound composed of N-acetylglucosamine and glucuronic acid, and is a type of polysaccharide that exists in the body, including skin, joint fluid, cartilage, and tears.

Hyaluronic acid has the property of being able to contain water hundreds of times its own weight, has a high viscosity, has an excellent moisturizing effect, and acts to block bacterial invasion, so it is used in artificial tears, cartilage injections, wound tissue regenerators, etc. It is used as.

In particular, hyaluronic acid is a major component that makes up the dermal tissue of the skin along with collagen and elastin, and is known to play a key role in improving wrinkles and maintaining skin elasticity.

Meanwhile, fillers used in procedures such as wrinkle improvement in the skin care field are intended to supplement ingredients lost due to aging. In the past, external substances such as silicon were mainly used, but they had various side effects such as causing excessive immune responses. Recently, hyaluronic acid filler, which is a fundamental ingredient in the body and is biodegradable and biocompatible, has been widely used.

Collagen is produced by fibroblasts in the human body and is the main component of connective tissue most commonly found in the body. It is distributed throughout our body, including bones, skin, joints, membranes of various organs, and hair. It is a fibrous protein. In addition, a lot of collagen exists around the axons of central and peripheral nerves.

Since collagen hydrogels present in the body have slightly different functions and roles depending on the tissue area, the collagen concentration and degree of orientation of the collagen hydrogels in each area are different. For example, bones are characterized by a structure in which micro/nanocrystalline minerals are located between oriented collagen fibers.

Collagen is a fibrous solid that is widely distributed in multicellular animals and is a structural protein made up of over a thousand amino acids to form a long, thin band. Collagen on the market is mostly heterogeneous collagen extracted from animal tissues such as fish, pigs, or cows. Depending on the use, Atelo collagen, in which telopeptides have been removed using enzymes, is sometimes used, if necessary.

Collagen is a biodegradable and biocompatible material that is widely used as a medical material such as wound dressing, tissue repair, skin graft, bone graft, and cell culture. It is also used as a moisture supplement in many cosmetics because it can absorb and release moisture. .

In addition, when collagen is lacking in the skin or when the skin ages, elasticity and luster are lost due to atrophy of the subcutaneous muscles, and blemishes, wrinkles, and age spots appear. If collagen is lacking in the bones, the bones become weak and there is a risk of developing osteoporosis, arthritis, joint pain, and swelling. It is reported that a lack of collagen in blood vessels causes arteriosclerosis and scurvy. For this reason, collagen is used for a variety of purposes, including health supplements, treatments, and cosmetics.

In order to use collagen for various purposes, collagen extracted from its natural state must be processed to suit the corresponding purpose and its physical properties must be adjusted. Conventionally, acellular dermis was freeze-dried and then processed into products, but this process had the problem of high cost and low productivity. In particular, when trying to manufacture freeze-dried acellular dermis into powder through a post-process, it was difficult to grind, etc. Because of this, there was great difficulty in making it into a fiber with many uses.

As a conventional medical compression bandage, a knitted fabric or fabric woven with covering yarns in which spandex yarns are effective yarns or nylon 66 yarns has been widely used. However, the conventional medical compression bandages are used to absorb sweat discharged from the human body. The ability to quickly absorb and then diffuse was poor, resulting in poor thermal conductivity and poor contact cold sensitivity, which resulted in poor breathability and wearing comfort.

Meanwhile, as another conventional medical compression bandage, Republic of Korea Patent Publication No. 10-2011-0052009 discloses a medical compression bandage in the form of fabric woven with draw textured yarn (DTY yarn: Draw Textured Yarn), but the conventional medical compression bandage is Although it has the effect of gaining a certain degree of elasticity without using spandex yarn (rubber yarn), which can cause skin diseases, it lacks elasticity and at the same time has a poor ability to quickly absorb and diffuse sweat released from the human body, resulting in thermal conductivity. And there was a problem of poor contact cooling sensitivity.

As another conventional medical compression bandage, Republic of Korea Patent Publication No. 10-2010-0012625 discloses a medical cushion bandage, which is a light fabric with cushion threads repeatedly inserted between the surface yarns and the back yarns, but quickly absorbs sweat discharged from the human body. There was a problem with poor thermal conductivity and poor contact cold sensitivity due to poor diffusion function.

Korean registered patent, KR No. 10-0993600, “Manufacturing method of medical cushion bandage and cushion bandage”, (registration date: November 4, 2010)

The object of the present invention is to provide a medical compression band that has good elasticity and is capable of quickly absorbing and diffusing moisture and sweat discharged from the human body, thereby providing excellent heat conductivity, contact cold sensitivity, breathability, and wearing comfort.

In order to achieve this task, the present invention manufactures a medical compression band using a fabric or knitted fabric woven with a double covering yarn in which the primary effect yarn and the secondary effect yarn are sequentially covered with the core Spakdex yarn.

At this time, the secondary effect yarn is a yarn containing a core-sheath type composite fiber in which a core part of a polyester polymer and a sheath part of an absorbent polymer having a hydrophilic group are compositely spun, and the primary effect yarn is used. As the effect yarn, yarn containing the core-sheath type composite fiber may be used, or nylon 6 yarn or nylon 66 yarn may be used alone.

The medical compression band according to the present invention is capable of quickly absorbing and relieving moisture and sweat discharged from the human body, thereby demonstrating excellent thermal conductivity and contact cold sensitivity while improving breathability and wearing comfort.

The present invention provides a medical compression band using hyaluronic acid, which is a fundamentally existing component in the body and is biodegradable and biocompatible.

Therefore, the present invention has the advantage of being able to use a medical compression band that can be safely and easily attached to the skin compared to hyaluronic acid fillers, which are conventionally prepared to be injected directly into the skin in the form of an injection.

In particular, the present invention eliminates the problem of dripping or moisture evaporation that occurs when applying hyaluronic acid in solution form externally, as in the prior art, and configures low molecular weight hyaluronic acid in the form of a sheet to be banded closely to the skin to increase absorption rate. It has excellent benefits in that it improves wrinkles and elasticity and improves and maintains moisturizing power while continuing gradually.

Figure 1 is a cross-sectional view of a core-sheath type composite fiber.
Figure 2 is a schematic diagram of the process for manufacturing double covering yarn.
Figure 3 is a cross-sectional view of the core-sheath type composite fiber.
Figure 4 is a cross-sectional view of the core-sheath type composite fiber.

Hereinafter, the present invention will be described in detail with reference to the attached drawings.

The medical compression band of the present invention has a knitted structure in which yarns are knitted into warp or weft knits, and the yarns are double covering yarns in which the yarns are covered twice in order by primary effect yarn and secondary effect yarn.

The core is a spandex yarn, and the secondary effect yarn includes a core-sheath type composite fiber in which a core part of a polyester polymer and a sheath part of an absorbent polymer having a hydrophilic group are compositely spun.

Specifically, the secondary effect yarn may be (i) entirely made of the core-sheath type composite fiber, (ii) only part of the core-sheath type composite fiber, and the remaining part may be nylon 6 yarn or nylon 66 yarn, etc. It may be made of nylon yarn.

The primary effect yarn may be (i) only part of the core-sheath type composite fiber and the remaining part may be nylon yarn, or (ii) may be entirely nylon yarn.

The absorbent polymer having a hydrophilic group constituting the sheath portion (Y) of the core-sheath type composite fiber is an ethylene-vinyl alcohol-based copolymer.

It is preferable that the fineness of the core-sheath type composite fiber be relatively thicker than the fineness of the spandex yarn as the core to improve thermal conductivity and contact cold sensitivity.

Looking at an example of a method for manufacturing the double covering yarn constituting the medical compression band of the present invention, as shown in Figure 2, the core material (C) is withdrawn from the bobbin (B1) mounted on the creel and the tension adjusting device (2) is used. After adjusting the tension uniformly as it passes, it is guided upward while passing it through the internal hollow part of the primary spindle (3), and at the same time, the primary effect yarn (E1) is pulled from the bobbin (B2) inserted into the primary spindle (3). It is drawn out and first covered over the core material C to form a single covering yarn, and the single covering yarn is then guided upward while passing through the internal hollow part of the secondary spindle 3', and at the same time, the secondary spindle (3') The secondary effect yarn (E2) is withdrawn from the bobbin (B3) inserted in 3') and covers the single covering yarn to manufacture a double covering yarn.

Hereinafter, the present invention will be examined in more detail through examples and comparative examples.

However, the scope of protection of the present invention is not limited to the following examples.

Example 1

Spandex yarn (fine yarn) is knitted into a weft knitted tissue with a double covering yarn in which (i) nylon 66 (primary effect yarn) and (ii) core-sheath type composite fiber (secondary effect yarn) are sequentially covered to produce medical compression. A band was prepared.

The core-sheath type composite fiber (secondary effect yarn) was composed of a core portion (X) of polyester polymer and a sheath portion (Y) of ethylene-vinyl alcohol-based copolymer.

Example 2

It is a double covering yarn in which the spandex yarn (fine yarn) is sequentially covered by (i) nylon 66 (primary effect yarn) and (ii) a mixed yarn of nylon 66 yarn and core-sheath type composite fiber (secondary effect yarn). A medical compression band was manufactured by knitting it with gastric tissue.

The core-sheath type composite fiber (secondary effect yarn) was composed of a core portion (X) of polyester polymer and a sheath portion (Y) of ethylene-vinyl alcohol-based copolymer.

Example 3

Spandex yarn (fiber yarn) is sequentially covered by (i) a mixed yarn of nylon 6 yarn and core-sheath type composite fiber (primary effect yarn) and (ii) core-sheath type composite fiber (secondary effect yarn). A medical compression band was manufactured by knitting the double covering yarn into a weft knit tissue.

The core-sheath type composite fiber (secondary effect yarn) consisted of a core part (X) made of polyester polymer resin and a sheath part (Y) made of an ethylene-vinyl alcohol-based copolymer.

Comparative Example 1

A medical compression band is manufactured by knitting a double covering yarn with a weft knit structure in which spandex yarn (screening) is sequentially covered by (i) nylon 66 (primary effect yarn) and (ii) nylon 66 yarn (secondary effect yarn). did.

The core-sheath type composite fiber (secondary effect yarn) was composed of a core portion (X) of polyester polymer and a sheath portion (Y) of ethylene-vinyl alcohol-based copolymer.

The medical compression band manufactured in Examples 1 to 3 and the medical compression band manufactured in Comparative Example 1 were stored at room temperature 20°C for 3 days and then the amount of instantaneous heat transfer was measured when the medical compression band was brought into contact with human skin. As a result of comparing the maximum heat absorption rate (Q·max) of each sample, the maximum heat absorption rate of each of the medical compression bands manufactured in Examples 1 to 3 was 0.15 J/cm2·sec or more, indicating cold sensitivity to contact. Although excellent, the maximum heat absorption rate of the medical compression band manufactured in Comparative Example 1 was less than 0.1 J/cm2·sec, and the contact cold sensitivity was poor.

The yarn may be microfiber containing collagen. Collagen is a type of bone protein. It can be used as a major component of connective tissues such as cartilage and skin. In general, collagen is not very soluble in water, and when treated with acid or base and then heated, it can decompose and turn into gelatin. This collagen can form a hydrogel state in water. In general, in the case of collagen, it is known that the absorption rate in the human body increases when collagen with a low molecular weight is used, and collagen with a low molecular weight is also known to have a higher moisturizing effect due to its higher compatibility with the human body.

In the case of collagen, which is manufactured using commonly used animal skin as a raw material, it is a high-molecular collagen with a molecular weight exceeding 5000 Da and can be produced in large quantities. It has the advantage of being thermally and chemically stable, but its absorption rate in the human body is low due to its high molecular weight. It may fall. Therefore, in the case of the present invention, by using collagen with a molecular weight of less than 1500 Da contained in the skin of the fish, especially the scales, it is possible to manufacture a fabric with higher human compatibility and moisture retention compared to yarn containing existing collagen.

For this purpose, the collagen includes collecting scales and skin of fish; Treating the collected scales or skins with a weak acid to remove fat and wash them; A first protein decomposition step of mixing 100 to 300 parts by weight of a basic solution with 100 parts by weight of the weakly acid-treated skin and scales and applying ultrasound; After the first protein decomposition step, mixing an acidic solution to neutralize pH to 6-8 and washing; After the washing is completed, a secondary protein decomposition step of adding 1 to 10 parts by weight of proteolytic enzyme based on 100 parts by weight of the skin and scales, and then reacting at a temperature of 50 to 70 ° C. for 10 to 20 hours; After the second proteolytic step, inactivating the proteolytic enzyme by heating to 90-110°C; Adsorbing and separating impurities by adding 3 to 10 parts by weight of activated carbon relative to the total liquid volume; and removing residues using a filter, then vacuum concentrating and freeze-drying the filtered liquid to powder it.

The fish used in the present invention are preferably those that have large scales and are easy to collect, such as sea bream, salmon, sea bass, and croaker. In the case of existing fish collagen, the skin of cartilaginous fish such as sharks or stingrays was used, or species with thick skins such as eels and catfish were used. However, the collagen of this skin has the characteristic of having a high molecular weight, just like animal skin. In the case of the present invention, it is more preferable to manufacture it using fish scales. However, since it is difficult to collect fish scales separately, it is preferable to collect and use the scales and skin of fish with large scales as described above.

The skin and scales of the above-mentioned fish can be collected from the residue remaining after processing the fish. Generally, the muscle tissue (flesh and internal organs) of fish are consumed, and the skin and bones are discarded. Therefore, in the present invention, it is preferable to produce the low molecular weight collagen using the discarded skin parts and scales contained in the skin.

The skin and scales collected as above can be treated with weak acid to remove fat. In the case of fish, it is known that fat is generally accumulated on the skin or other adjacent areas. However, in the case of these fat components, when combined with basic components to be described later, they may be saponified and interfere with the production and separation of collagen. Therefore, it is desirable to remove fat using a weak acid before the protein decomposition step using basic ingredients.

The weak acid used at this time is preferably acetic acid. When using strong acids such as hydrochloric acid, the fat removal efficiency can be increased, but since it decomposes the calcium contained in the scales, the scales are decomposed, making it difficult to extract collagen in the process described later, and the residue can cause damage to the human body. Therefore, it is preferable to decompose fat using acetic acid used for food. At this time, the weak acid has a concentration of 1 to 10 M, and 10 to 30 parts by weight can be used relative to 100 parts by weight of the skin and fat. In the above concentration range, the separation of the fat can be effectively performed, but if it is below the above range, it may be difficult to remove the fat, and if it exceeds the above range, the acidity increases and the scales are decomposed or the remaining acetic acid causes the protein decomposition process to be described later. This may not be easily accomplished.

As described above, after the fat has been removed with a weak acid, the scales and skin can be washed and used.

The first protein decomposition step can be performed on the skin and scales from which the fat has been removed by mixing 100 to 300 parts by weight of a basic solution with 100 parts by weight of the skin and scales and applying ultrasound. The first protein decomposition step is a process of decomposing the protein present in the scales or shells using a basic solution and ultrasound. Collagen, the main protein contained in the scales and shells, is broken down and dissolved in water at the same time. This is a step to reverse the tissue so that collagen extraction using proteolytic enzymes, which will be described later, can be easily performed.

At this time, in the case of the previously used basic solution, a strong base, such as sodium hydroxide or potassium hydroxide, was used for convenience of use, but in this case, the remaining basic solution may irritate the skin. Therefore, in the case of the present invention, it is preferable to prepare and use a basic solution using calcium carbonate. In particular, since the collagen of the present invention can be used in contact with the skin, the calcium carbonate can also be used as a product manufactured using clam shells rather than an industrially synthesized product.

To this end, the basic solution includes the steps of separating clam shells and then washing them; Calcining the washed clam shells at a temperature of 800 to 1200°C; Crushing the fired clam shell; Mixing the pulverized clam shells with 1000 to 5000 parts by weight of water based on 100 parts by weight of the clam shells, and then leaving for 2 to 10 days; And it may be a solution prepared by a method comprising the step of separating the solid content of the clam shell.

The shell of the clam is composed mainly of a large amount of calcium carbonate, and most of it is disposed of as waste. Therefore, when calcium carbonate is extracted and used from these shells, it can achieve the desired effect while contributing to resource recycling and environmental protection. The clam shells may be washed and organic matter removed, and then fired at a temperature of 800 to 1200°C. Through this, organic matter and other impurities present in the shell may be oxidized and removed, leaving only calcium carbonate. At this time, if the calcination temperature is less than 800°C, smooth calcination may not be achieved, and if it exceeds 1200°C, not only does energy use increase, but calcium carbonate may be decomposed during calcination, resulting in a decrease in yield.

After the firing is completed as described above, it can be pulverized, mixed with 1000 to 5000 parts by weight of water relative to 100 parts by weight, and then left for 2 to 10 days to prepare an aqueous calcium carbonate solution. At this time, if less than 1000 parts by weight of water is used, the amount of aqueous solution produced may be reduced, which may reduce efficiency. If more than 5000 parts by weight of water is used, the concentration of calcium carbonate will be low and the effect of calcium carbonate cannot be expected. .

The basic solution may be added in an amount of 100 to 300 parts by weight based on 100 parts by weight of the scales and shells. If the basic solution is added in less than 100 parts by weight, extraction of collagen may not be easy, and if it is added in excess of 300 parts by weight, a lot of energy is required in the powdering process, which will be described later, making it uneconomical.

In order to more efficiently extract proteins using a basic solution as described above, ultrasound waves can be supplied to the mixture of the basic solution and the scales and shells. In the case of the ultrasonic wave, it can cause resonance shapes with various materials depending on its frequency. In the case of the present invention, it can serve to further accelerate extraction by the basic solution by decomposing the collagen contained in the skin and scales. Obviously, the collagen extraction according to the present invention is performed using a weak base material, unlike the existing extraction method using a strong base, and thus collagen can be extracted with efficiency similar to the existing method by supplying ultrasound as described above.

The ultrasonic waves used at this time have a frequency of 20 to 130 kHz and can be supplied at an intensity of 300 to 800 W. If the ultrasonic waves are outside the above frequency range, they may not cause a resonance phenomenon with collagen and the extraction efficiency may decrease. If the ultrasonic waves are supplied at an intensity of less than 300W, it is difficult to expect an effect of increasing the extraction by ultrasonic waves. In addition, if supplied at an intensity exceeding 800W, the decomposition strength of collagen becomes stronger and the molecular structure of collagen may be decomposed, thereby reducing extraction efficiency.

After the extraction using basic solution and ultrasound is completed as described above, it is preferable to neutralize using an acidic solution. The acidic solution used at this time is preferably a natural acidic solution like the basic solution, and the acidic solution is a mixture of at least one selected from the group consisting of lemon juice, citron juice, sugared citron juice, orange juice, and vinegar. can be used. That is, when the extraction using the basic solution is completed, the acidic solution can be added to neutralize the reaction to pH 6 to 8, preferably pH 7, to terminate the reaction.

Even after collagen is eluted using a basic solution as described above, a lot of collagen may exist between scales and skin tissues. Therefore, it is desirable to extract it using proteolytic enzymes. The proteolytic enzyme used at this time is preferably an endo-type proteolytic enzyme (Alcalase).

Through the above process, proteins present in the scales and skin can be decomposed and extracted, and collagen can be eluted and separated during this process.

It is preferable to add 1 to 10 parts by weight of the proteolytic enzyme based on 100 parts by weight of the skin and scales and then react for 10 to 20 hours at a temperature of 50 to 70 ° C. Under the above conditions, the extraction efficiency of the proteolytic enzyme can be maximized, but if it is below the above range, the extraction efficiency by the acidic proteolytic enzyme may decrease, and if it exceeds the above range, there is no further efficiency improvement and expensive proteolytic enzyme is used. It is inefficient because it increases usage. In addition, if the temperature exceeds 70°C during the reaction, the proteolytic enzyme may be denatured and its activity may decrease.

After extraction of collagen by proteolytic enzyme is completed as described above, it is preferable to inactivate the proteolytic enzyme by heating to 90-110°C. In the case of the proteolytic enzyme, if stored for a long period of time with collagen, there is a possibility of deforming the molecular structure of the collagen itself. Therefore, it is desirable to inactivate the proteolytic enzyme by denaturing the proteolytic enzyme through heating. At this time, if heating is performed at a temperature below 90°C, the inactivation of the proteolytic enzyme may not be complete, and if heating is performed at a temperature exceeding 110°C, collagen may be denatured.

After inactivation of the proteolytic enzyme, it is preferable to add 3 to 10 parts by weight of activated carbon relative to the total liquid volume to coalesce and separate impurities. In the case of the collagen of the present invention, since it is extracted using the skin and scales of the fish, a fishy smell peculiar to the fish may be emitted after the extraction is completed. In the case of this fishy smell, it is caused by impurities extracted by decomposition like collagen, and is preferably removed by adsorption using the activated carbon. At this time, since the collagen has a larger size than the pores of the activated carbon, impurities causing the fishy smell can be selectively adsorbed and separated, and the inactivated proteolytic enzyme can also be removed.

Once the separation of impurities as described above is completed, the residue can be removed using a filter. In the case of the collagen, it can be liquefied through the above extraction process, and the remaining tissues can remain in a solid state. Therefore, the collagen can be separated by separating it using a filter. In particular, since the activated carbon can also be separated during this process, low-molecular-weight collagen with a reduced fishy smell can be obtained.

The liquid collagen separated as described above can be powdered through vacuum concentration and freeze-drying processes.

Yarn can be manufactured using collagen prepared as above.

The yarn includes a first fiber formed in a star shape with 2 to 10 arms in cross section, including branches extending radially from the center; and a second fiber located between the branches of the first fiber and having a wedge-shaped, triangular, or fan-shaped cross-section (see Figure 2).

The first fiber is a part that forms the center of the yarn and includes a branch portion 320 extending radially from the center 310 and may be formed in a star shape with 2 to 10 arms in cross section. This first fiber is a part that constitutes the thickness and shape of the yarn and may be composed of a central part and a branch part.

The central part 310 is a part that forms the center of the first fiber, and the branch parts may be arranged at equal intervals along the circumference to form a star shape.

The branch portions 320 are parts disposed at equal intervals in the center, and second fibers 330, which will be described later, are disposed between each branch portion, and may be formed to form a circle in the overall cross section. The branch portion may be formed in the longitudinal direction of the fiber. Accordingly, the fiber may have a cross-sectional shape such that a plurality of branches form arms based on the center, such as a star shape or a starfish shape. . At this time, 2 to 10 branch parts may be formed, and if the number of branch parts exceeds 10, the thickness of the second fiber 330, which will be described later, may become thin and durability may decrease.

The first fiber may include nylon 6, nylon 66, or polyethylene terephthalate. The first fiber forms the center of the yarn and is a part that determines the strength of the yarn, so it is preferably manufactured using a fiber with high strength. In particular, in the case of nylon 6 or nylon 66, it is desirable to manufacture the first fiber using nylon 6 or nylon 66 because it has excellent fiber properties and high durability.

The second fiber 330 is located between branches of the first fiber and can enable the yarn to have a circular cross-section. Through this, most of the surface of the yarn is formed such that the second fiber is exposed, and accordingly, the surface characteristics of the yarn can be determined by the second fiber.

That is, in the case of the yarn, the physical properties may have the characteristics of the first fiber constituting the center, and the surface properties may be determined depending on the second fiber, so it is manufactured as a human-friendly fiber while having high physical properties. It can be (see Figure 2).

At this time, in the case of the second fiber, the cross section may be manufactured in a wedge-shaped triangle or fan shape so that it can be formed between branches of the first fiber. Through this, the second fiber can be located between the branches of the first fiber, and the overall shape of the yarn can be circular. In addition, as seen above, since most of the outer peripheral surface of the yarn is composed of exposed second fibers, it is possible to manufacture yarn having the effects of the second fibers.

The second fiber is preferably a polymer containing 2 to 40% by weight of collagen. Through this, the moisturizing effect caused by the collagen can be expected. At this time, if the collagen is included in less than 2% by weight, it is difficult to expect the effect of collagen, and if the collagen is more than 40% by weight, the durability of the second fiber may decrease and the durability of the yarn may decrease.

As described above, the first fiber and the second fiber may be configured to have a gap of 0.001 to 0.01㎛. The first fiber and the second fiber can be manufactured according to a manufacturing method to be described later, so that the fibers are separated at regular intervals. At this time, the space between the first fiber and the second fiber can be used as a space where water and moisture are absorbed through capillary action, so the moisture control effect by the yarn can be maximized. In addition, the moisture absorbed as described above is re-released when the surface of the human body dries, and it is possible to have a moisturizing effect along with the collagen.

In addition, as the fibers are manufactured to have a certain space between the fibers as described above, the fibers can have the ability to absorb odors. In general, the human body emits various chemicals along with sweat in the form of waste products, which can emit a specific odor in that state or emit a unique scent when decomposed by bacteria. Therefore, when these chemicals are adsorbed, they can be made into fabrics with so-called deodorizing properties. In the case of the present invention, as it is manufactured to have a supply between the fibers, the chemical substances can be easily adsorbed and removed, and thus a fabric with high deodorizing power can be manufactured.

The yarn may be produced by spinning the first fiber and the second fiber and then stretching them.

To this end, the yarn includes: (a) a first spinning step of spinning a first fiber raw material through a nozzle having a radially extending branch; (b) a second spinning step of passing the first fiber spun in the first spinning step through a cylindrical nozzle and spinning the second fiber material to penetrate between the arms of the first fiber; (c) a stretching step of stretching the fiber to a desired thickness after the second spinning step; (d) separating the first fiber and the second fiber by immersing the fiber in a basic solution after the stretching is completed; (e) a neutralization step of immersing the separated first and second fibers in an acidic solution; and (f) washing the fiber after the neutralization step is completed, separating and drying the resulting salt.

The step (a) is a step of manufacturing the first fiber by spinning the first fiber raw material, and it is preferable to spin the first fiber raw material through a nozzle having a radially extending branch. At this time, the nozzle may be heated to a temperature of 260 to 300° C. to spin the first raw material.

The first fiber raw material that has passed through the nozzle having the radially extending branch is melted by the heated nozzle to form the first fiber. At this time, the first fiber may be hardened after passing through the nozzle, and may be hardened on the surface before contact with the second fiber raw material, thereby minimizing fusion with the second fiber.

The step (b) is a second spinning step in which the first fiber spun in the first spinning step is passed through a cylindrical nozzle and the second fiber raw material is spun to penetrate between the arms of the first fiber. This is the step of forming two fibers between the branches of the first fiber. Since the nozzle for the second spinning step has a circular shape as described above, the surface of the yarn may have a circular shape. In this case, if the diameter of the circular nozzle is formed to be the same as the outer diameter of the first yarn, The second fiber raw material may be introduced between the branches of the first fiber.

When the cylindrical yarn is spun through step (b), the second spinning step (c) of stretching the fiber may be followed by a stretching step of stretching the fiber to a desired thickness. In the case of the spun yarn, it is possible to form a yarn thicker than microfiber due to limitations in spinning. In addition, immediately after spinning is completed as described above, the first fiber and the second fiber are spun in a state of adhesion. Therefore, through the stretching process, the yarn can be formed to a desired thickness and mechanical stress can be applied to the first and second fibers to reduce adhesion between the two fibers.

After the stretching in step (c) is completed, (d) after the stretching is completed, the step of separating the first fiber and the second fiber by immersing the fiber in a basic solution may be performed. In the case of the first fiber and the second fiber, the solubility of the base may be different. In particular, since the second fiber contains collagen, the solubility of the base may be different from that of the first fiber. Using this, the first fiber and the second fiber can be separated by immersing the spun and drawn yarn in a basic solution.

At this time, it is preferable to use a basic solution (aqueous sodium carbonate solution) prepared using the same clam shell as that used for collagen use.

After the separation step of the first fiber and the second fiber using the basic solution is completed, (e) a neutralization step of immersing the separated first fiber and the second fiber in the acidic solution may be performed. The basic solution used in step (d) is slightly acidic, but if used as is on a blanket, it may have a negative effect on the user's skin. Therefore, it is desirable to neutralize it using an acidic solution. The acidic solution used at this time is the same natural acidic solution used when producing the collagen, that is, a mixture of at least one selected from the group including lemon juice, citron juice, sugared citron juice, orange juice, and vinegar. desirable.

The yarn manufactured as above can be manufactured by washing it with water to remove salts generated during the neutralization process and then drying it.

The fabric may be produced including the yarn. At this time, the yarn may be included in 10 to 30% by weight of the fabric. If the yarn is included in the fabric in less than 10% by weight, it is difficult to expect the effect due to the collagen, and if the yarn is included in more than 30% by weight, the feel of the quilt made of the fabric may be poor or the durability may be reduced. You can.

The yarn (polymer monofilament) used in combination with the collagen-containing yarn can be used as a type of modal rayon. The modal is a yarn that has a texture similar to cotton, has less shrinkage and excellent elasticity compared to cotton, and has a subtle gloss, so it can have an excellent texture when used in the blanket. In particular, in the case of the present invention, it is possible to produce a blanket with excellent tactile feel by using modal made from beech wood.

The fabric is a warp fabric manufactured by mixing 1 to 30 strands of polymer monofilament and the yarn containing the collagen at a ratio of 1 to 10% by weight; Weft yarn manufactured by mixing 1 to 30 strands of polymer monofilament and the yarn containing the collagen at a ratio of 1 to 10% by weight; And it may include a reinforcing yarn inserted into the warp and weft yarns at regular intervals and composed of 10 to 100 strands of the polymer monofilament.

At this time, the warp refers to yarns that are vertical when the fabric is peeled, and the weft, unlike this, refers to yarns arranged horizontally. It is possible to use the same manufactured yarn for these warp and weft threads, but it is also possible to use differently manufactured yarn to vary the elasticity and other physical properties in the vertical and horizontal directions. In other words, by varying the types of threads used for the warp and weft threads, it is possible to produce a fabric with elasticity only in the vertical or horizontal direction, or to increase the adhesion in the vertical direction to produce a blanket that does not slip off when sleeping. do.

At this time, 1 to 30 strands of polymer monofilament may be used for the warp and weft yarns. As discussed above, the polymer monofilament can be made of modal, a type of rayon, and it is especially preferable to use modal made from beech wood. At this time, if more than 30 strands of the polymer monofilament are used, the thickness of the warp or weft threads may become thick and the feel of the fabric may deteriorate.

The reinforcing yarn is used to increase the strength of the fabric and may be inserted into the warp or weft at regular intervals. When the fabric is damaged, these reinforcing yarns can play a role in preventing the damage from spreading to the surrounding area. For this purpose, the reinforcing yarn is preferably produced by twisting a larger amount of monofilament than the warp and weft yarns. Specifically, the reinforcing yarn may be composed of 10 to 100 strands of the polymer monofilament. If the reinforcing yarn is composed of monofilament with less than 10 strands, there is no strength reinforcement effect by the reinforcing yarn, and if it exceeds 100 strands, the reinforcing yarn protrudes to the surface, which may affect the texture of the fabric.

In addition, it is preferable that the reinforcing yarns are mixed and woven at a ratio of 1 per 5 to 30 strands of the warp and weft yarns. If used at a ratio exceeding 1 per 5 strands of warp or weft, the texture of the fabric may deteriorate, and if used at a ratio of less than 1 per 30 strands, the effect of strengthening physical properties by the reinforcing yarn may be reduced.

At this time, the outer shell may include fixing means for coupling with the inner sheath 200, which will be described later. The fixing means 120 may perform the role of fixing the outer sheath and the inner sheath in a certain shape by pressing and fixing the endothelium 200. For this purpose, the fixing means may be an elastic band connected to the side of the cover part 110. In order to fix the endothelium, the elastic band may be fixed diagonally to the edge of the cover or may be fixed to connect both sides of the cover.

When fixed diagonally to the edge of the cover part 110, the endothelium can be fixed by pressing the edge of the endothelium (Figure 1(a)), and is fixed in a form that connects both sides of the cover part. In this case, the endothelium can be fixed in a way that puts pressure on it (Figure 1(b)).

The lining 200 may be made of fabric manufactured by weaving microfiber monofilaments having a thickness of 0.1 to 5 μm. The inner skin plays a role in preventing the thermal insulation material located inside the inner skin from leaking out. It is manufactured to have pores smaller than the thickness of the thermal insulation material, so that the thermal insulation material does not leak into the inner skin. It is desirable to be manufactured so that air can flow. Through this, not only can the active ingredients of the herbal medicine contained in the thermal insulation material volatilize to the outside, but also the phosphoric acid moisture control effect can be maximized by the collagen contained in the outer skin. If the thickness of the microfiber used in the inner skin is less than 0.1㎛, not only will the durability of the inner skin decrease, but the size of the pores formed in the inner skin may decrease, which may reduce the flow of air. Microfibers with a thickness exceeding 5㎛ may be used. When used, the feel of the inner skin deteriorates and the size of the pores increases, causing the thermal insulation material inside to leak out.

The thermal insulation material is present inside the endothelium and plays a role in maintaining the user's body temperature, thereby minimizing air flow inside the endothelium to maintain a constant temperature.

For this purpose, the thermal insulation material includes a non-woven fabric layer formed of microfibers with a thickness of 0.1 to 30 μm; And it may include herbal medicine adsorbed on the non-woven fabric layer.

In the case of the above thermal insulation material, it is desirable to use microfiber so that it can not only contain a large amount of air but also maintain thermal insulation despite changes in humidity. Natural thermal insulation material used in Gizoneng, especially duck down, is an insulation material made from bird fur and is light in weight and can contain a lot of air, so it is light and has an excellent thermal insulation effect. However, when it comes in contact with moisture, it clumps up with adjacent fur and loses warmth. It has the disadvantage of rapidly decreasing. Therefore, in the case of the present invention, it is preferable to use a non-woven fabric layer made using microfibers that can replace such natural thermal insulation materials as the thermal insulation material. At this time, the microfibers preferably have a thickness of 0.1 to 30㎛, and in particular, microfibers thicker than the microfibers used for the endothelium can be used. The microfibers used in the endothelium can form voids of a certain size by weaving, and the size of these voids may be proportional to the thickness of the microfibers used in the endothelium. Therefore, when the microfibers used in the thermal insulation material are thicker than the thickness of the microfibers used in the inner skin, leakage of microfibers through the inner skin can be minimized.

Additionally, the microfibers may be manufactured in the form of non-woven fabric. In the case of existing nonwoven fabrics, they are manufactured by laminating fibers and then compressing them, but in the case of the present invention, nonwoven fabrics can be manufactured by laminating microfibers, then performing a process of inflating them, and combining each fiber. Therefore, the thermal insulation material of the present invention can have a high thermal insulation effect because it contains a large amount of air while being light in weight.

Herbal medicine may be adsorbed to the non-woven fabric layer. The oriental herbal medicine volatilizes and supplies active ingredients to the human body during sleep, thereby providing active ingredients and scents that can help with sleep.

For this purpose, the oriental herbal medicines include licorice, peppermint, chrysanthemum, Aspergillus, ephedra, Cheongung, mugwort, Angelica root, Baekji, Sinhwa, Eucommia, Ayeop (mugwort), Gobon, Cheoncho, Jincho, cinnamon, health, windbreak, ginseng, Gilgyeong, Baekbokryeong. Drying one or more herbal medicines selected from the group of Yukjongyong, Baeksil, Uiyin, White Rice, Small Fennel, Mokhyang, Bimmu and Bryeom, and then pulverizing them to a size of 0.01 to 1 mm; The step of charging the pulverized herbal medicine into a puffer and then swelling it by heating it at a pressure of 1 to 3Mpa and a temperature of 100 to 300°C; Immersing the puffed herbal medicine in water and then supplying ultrasonic waves with a frequency of 50 to 80 Hz at an intensity of 300 to 800 W for 3 to 10 minutes; And after the ultrasonic supply is completed, the puffed herbal medicine is mixed with water in which it is immersed and dried, thereby reabsorbing the eluted active ingredient.

The oriental herbal medicine can be used by combining various oriental herbal medicines, but it can be used by mixing herbal medicines that are generally known to help the human body sleep and herbal medicines that have a good effect on the human skin. Through this, the thermal insulation material containing the herbal medicine can volatilize and supply the active ingredients contained in the herbal medicine through the flow of air during sleep.

The herbal medicines used at this time include licorice, peppermint, chrysanthemum, asparagus, ephedra, cheongung, mugwort, angelica root, baekji, sinhwa, eucommia, ayeop (mugwort), gobon, cheoncho, Jincho, cinnamon, health, windbreak, ginseng, gilgyeong, and baekbokryeong. , one or more species selected from the group of Yukjongyong, Baeksil, Uiiin, White Rice, Sofenhyang, Mokhyang, Bimmu, and Bryeom can be used.

The herbal medicine may be dried and then ground to a size of 0.01 to 1 mm. In the case of the herbal medicine of the present invention, the foreign matter should not feel foreign while being adsorbed to the insulation material, and it is desirable that it not leak out of the endothelium. Therefore, it is preferable to use the herbal medicine by grinding it to a size of 0.01 to 1 mm. At this time, if the size of the herbal medicine is less than 0.01 mm, it may leak out of the endothelium, and if it is larger than 1 mm, a foreign body sensation may be felt when using the blanket.

The pulverized herbal medicine can be charged into a puffer and then heated to a pressure of 1 to 3Mpa and a temperature of 100 to 300°C to cause swelling. Through this process, the density of the herbal medicine can be lowered, thereby reducing the feeling of foreign matter, and it has porosity, so the volatilization of the active ingredient can become more smooth. At this time, if the swelling is performed below the above temperature and pressure, the swelling may not be smooth and the volatilization of the active ingredient may decrease. If the temperature and pressure are exceeded, the herbal medicine may be carbonized at the same time as it requires a lot of cost.

After immersing the puffed herbal medicine in water, ultrasonic waves with a frequency of 50 to 80 Hz can be supplied at an intensity of 300 to 800 W for 3 to 10 minutes. The ultrasonic waves can decompose part of the cellulose by resonating with the cellulose of the herbal medicine, thereby making it easier to volatilize the active ingredients contained in the herbal medicine. However, since this ultrasonic supply process is preferably performed in water, it is preferable to evaporate the supplied water and re-absorb the active ingredient eluted in the water after the ultrasonic supply is completed.

The re-adsorption process is a step of supplying the active ingredient eluted in the water back to the porous herbal medicine. The active ingredient eluted in the water is uniformly supplied to the herbal medicine to prevent concentration differences depending on the location of each herbal medicine. It can be minimized. Since the herbal medicine is used after being pulverized, it is generally adsorbed at a uniform concentration within the nonwoven fabric. However, since there may be differences in composition depending on some locations, it is desirable to uniformize the concentration of the active ingredients of the herbal medicine through the above process. In addition, through this process, the active ingredient eluted to the outside during the ultrasonic supply process can be re-adsorbed, and since the active ingredient can be adsorbed on the surface of the herbal medicine, the amount of volatilization of the effective ingredient can also increase.

The outer shell is manufactured using a fabric containing the collagen and can form the outermost layer of the blanket. The fabric may constitute a cover part of the outer skin that is in contact with the human body, and accordingly, the cover part and the human body can come into contact to bring about a moisture retention effect due to collagen and microfibers in the human body.
