A natural mineral-contained multi-functional textile consisting of two different layers}

The present invention is poly consisting of ester-based fibers and the nylon-based layer forms a double-surface structure of a surface layer consisting of a fiber, the present invention relates to a health functional fiber, it characterized in that it contains a natural mineral component and the activated carbon component.

Elastic fibers are used in stockings, women's underwear, and stretch fabrics because of their excellent elasticity and elasticity, and their use as aerobics and receiving garments continues to expand. In addition, as interest in health and demand for functional fabrics increases, research on functional clothing that can help health through clothing is being actively conducted.

Health-promoting functional fabrics, especially clothing that stimulates body metabolism by activating far-infrared radiation and provide therapeutic effects to pain, are mainly needed by the elderly or those who are uncomfortable. It can also be applied to work clothes to reduce the fatigue of the body, or can be utilized as functional clothing that can quickly release the fatigue. However, conventional health functional textiles are mainly made of thin fabrics, which not only have a small amount of functional material that emits far infrared rays, but also incorporate active elastic materials. There is a need for the emergence of clothing that further improves functionality.

In the past, fibers having added functional ingredients such as natural jade, elvan, permanent magnet or germanium have been known. However, in the case of functional fibers manufactured by conventional methods, fibers having both the above functionalities, thermal insulation and elasticity are currently developed. It is not. In addition, there is a disadvantage in that durability is reduced as sportswear and work clothes due to the decrease in strength by the inorganic material between the fibers when the functional material is added in the step of manufacturing the stretch yarn.

In addition, although a method of post-processing a functional material on the stretchable yarn may be sought, there is a problem of deterioration in washing durability and touch. Therefore, there is an urgent need in the art for the emergence of fibers having sufficient far-infrared radiation, excellent thermal insulation, light weight and elasticity, excellent washing fastness and durability, and which can be manufactured through a stable process.

It is an object of the present invention to provide a multi-surface multifunctional fabric containing natural minerals and activated carbon having excellent four-way elasticity, warmth, absorbency, dryness and health functionalities at the same time.

In order to achieve the above object, the present invention forms a double surface structure of the back layer composed of polyester fibers and the surface layer composed of nylon fibers, and stretched in four directions, the polyester fibers are all fibers It contains a natural mineral component of 1 to 15% by weight and the nylon fiber provides a highly elastic health functional fiber, characterized in that containing 1 to 15% of the activated carbon component relative to the total fiber weight.

Hereinafter, the present invention will be described in detail.

As used herein, the term "multifunctional" is used to refer to various properties that contribute to health, and in particular, in this specification, various properties that the fiber may have in this context, such as stretch, antibacterial, It includes a function that can exhibit excellent characteristics such as deodorization, moisture absorption, light weight, thermal insulation, temperature control, and antistatic.

As used herein, the term "elasticity" refers to elasticity. In other words, it refers to the property of returning to the original state when the external force is removed after applying the external force to the elastic body. When the elastic body is in the four states (nylon, polyester, polyurethane, etc.), it is called an elastic yarn. If it is made of fabric, it is classified as stretch fabric.

As used herein, the term "antimicrobial" includes not only inhibiting the growth of pathogenic microorganisms such as bacteria, fungi, etc., but also inhibiting their sterilization by inhibiting their survival.

In the present invention, the term "heat insulation" refers to a property of preserving temperature, and represents a property by a function of insulating to prevent heat from escaping to an outer portion having a low temperature.

In the present invention, the term "hygroscopicity" is also referred to as moisture content, which means a property of absorbing moisture in humid air and dissipating moisture in dry air. Fiber products absorb some moisture in the air. The amount of water absorbed varies depending on the type of fiber and the type of fiber products (fibers, yarns, fabrics, etc.). It depends on the processing. Generally, fabrics made of highly hygroscopic fibers have good absorbency and dyeability.

As used herein, the term "deodorant" refers to a function of physically removing, chemically decomposing, or chemically or biologically disconnecting a causative agent of malodors to reduce or prevent malodors. The term 'deodorization' is also included in the above meaning, and the method of preventing odor by chemical and biological antibacterial by natural minerals and physical adsorption of odor molecules is used.

The term "health functional" used in the present invention promotes blood circulation due to the release of far-infrared rays, and is effective in preventing athlete's foot and sweat bands. It is a general term for various functions that maintain the physical condition.
In the present invention, the term "fiber" refers to a fiber yarn, the fiber yarn (filament, thread, yarn, etc.) is a constituent material of the fiber fabric. In the present invention, the term "fiber" is used interchangeably with filament and yarn.

“Fabric” also refers to products made from fibrous yarns, such as wovens, knits, felts, plaiteds, braids, laces, nonwovens, laminated and molded fabrics. And the like.

Hereinafter, the present invention will be described in detail.

In the present invention, weaving into a structural yarn forming a functional double surface layer in order to demonstrate the functionality of the four-way stretch fabric to produce a multi-functional fabric that can express the excellent function evenly by the strong wear resistance and wind resistance of the surface layer and the breathability and hygroscopicity of the back layer to provide.

Currently produced stretch fabrics include a method of using spandex yarn and a yarn processing of polyester yarn.

However, in the case of spandex yarn, since it is impossible to use alone in actual use, it is used by covering the elliptic yarn with spandex yarn. At this time, the mixing ratio between the other yarns is low, so that the sole property of the spandex is lost, and thus the inherent physical properties cannot be exhibited. In general, the elasticity of spandex has a cutting elongation of 400-800%, but it has a stretch of 10-30% in the fabric, which means that an elliptic crimp must be formed by spandex alone, and this shrinkage strength is low due to the mixing ratio problem. Inherent elasticity is excluded. Especially in the case of mixing with polyester yarn, not only the weight loss processing is impossible, but also the heat resistance is low (processing below 120 ° C), so that dyeing and processing are difficult.

The method of using polyester yarn processing is to use latent crimping yarn which strengthens the bimetal structure in which the shrinkage and looseness coexist in the cross section of the fiber itself, and the filament yarn at the temperature of 235 ° C which is close to the melting point of the heater in the flammable condition. There is a method of increasing the degree of orientation of the polymer by treating with high tension and producing and using high bulk twisted twisted yarn which makes the most of the crimp. However, this product is a polyester material, when applied as a teaching fabric, may not be applied depending on the dyeing conditions, there is a limit to the application for sports products that require a soft and light and high functionality.

Japanese Patent Laid-Open No. 10-72732 discloses a method of using two kinds of polyethylene terephthalate (PET) having intrinsic viscosity difference. In addition, Japanese Patent Application Laid-Open No. 2000-328378 and Japanese Patent Laid-Open No. 9-41234 disclose a method for producing a polyester-based latent crimp expressive fiber by using a general polyethylene terephthalate and a highly shrinkable copolymerized polyethylene terephthalate. have. In addition, U.S. Patent No. 3,671,379 and Japanese Patent Laid-Open No. 11-189923 use polytrimethylene terephthalate (PTT) or polybutylene terephthalate (PBT) having stretch properties to polyethylene terephthalate (PET). It also shows how. As described above, the conventional methods for producing stretchable composite fibers are only proposed for composite spinning using different polyester-based polymers.

However, the present invention relates to a double surface structure of a back layer composed of polyester fibers and a surface layer composed of nylon fibers, that is, a composite fiber of different kinds, and does not cause the above problems.

The dual structure of the present invention uses a stretch yarn only on the surface layer while having a thick fabric cross-section to give elasticity to the back layer at the same time, thereby reducing the content of an expensive span yarn, and moving elastically while the close portion closes to the skin softly. Compared to thick fabrics using spanners, it is more suitable for sports and leisure wear, which requires sufficient activity while protecting the body.

Structural yarns constituting the back layer is a pile yarn that adjusts the strength of the pile filament when brushed with a polyester filament of a triangular cross section prepared by mixing natural minerals during spinning.

Structural yarn constituting the back layer is a polyester filament of triangular cross section with single yarn fineness of 1 ~ 3 denier, and can add 1 ~ 15% by weight of natural mineral component in the spinning process to obtain antibacterial deodorization, far infrared radiation and antistatic effect. have. Preferably, mica may be used as the natural mineral component.

Polyester of the said back layer is defined as the polymer manufactured by polycondensation of diol and dicarboxylic acid. Dicarboxylic acids include terephthalic acid, isophthalic acid, phthalic acid, naphthalene dicarboxylic acid, adipic acid, and sebacic acid. Diols include ethylene glycol, trimethylene glycol, tetramethylene glycol and cyclohexane dimethanol. Particularly useful polyesters include polymethylene terephthalate, polyethylene terephthalate, polypropylene terephthalate, polyethylene isophthalate, polytetramethylene terephthalate, polyethylene-p-oxybenzoate, poly-1, 4-cyclohexylene dimethylene Terephthalate, and polyethylene-2, 6-naphthalate. Needless to say, these polyesters can be homopolymers or copolymers, and the copolymerization components are, for example, diol components such as diethylene glycol, neopentyl glycol, and polyalkylene glycols, and adipic acid, sebacic acid And dicarboxylic acid components such as phthalic acid, isophthalic acid and 2, 6-naphthalene dicarboxylic acid. In view of mechanical strength, thermal stability, chemical resistance, and durability, preferred in the present invention are polyethylene terephthalate, polypropylene terephthalate, polyethylene isophthalate, polyethylene naphthalate (polyethylene-2, 6-naphthalate), And copolymers thereof.

The polyester filament of the triangular cross section of the back layer material may have a higher level of hairiness than the general circular cross section yarn, and further increase the raising effect when raising the pile of the back layer formed of the polyester yarn. The brush layer adheres to the skin to quickly absorb liquid sweat and transfer it to the surface layer.A thick air layer is formed in the brush layer to prevent the body from lowering the body temperature caused by the liquid sweat generated during exercise. It protects your body from reducing the volume compared to the traditional winter clothing, while increasing the warming effect.

In addition, due to the loop forming and raising process, it may include a large amount of polyester yarn relative to the total weight of the double-structured fiber compared to the general knitted fabric, which will simultaneously increase the content of natural minerals contained in the polyester yarn. Can be.

The polyester fiber contains a natural mineral component upon spinning. Preferably, the natural mineral component is 1 to 15% by weight based on the total fiber weight.

Natural minerals are complex alkali minerals composed of substances with high natural calorific value and high infrared ray emission. Crystal, mica, kaolin, dolomite, etc. are used, and main components are 65% SiO ₂ , 18% AL ₂ O ₃ , The guitar is about 17%. These natural minerals are excellent in antimicrobial activity and far infrared ray emission amount, and excellent in the ability to decompose and neutralize volatile organic compounds (VOC). The natural mineral component used in the present invention is preferably at least one material selected from quartz, mica, kaolin, and mica. Most preferably it is a dolomite.

The method of manufacturing the polyester fiber containing a natural mineral component is as follows. About 85 to 99% by weight of the raw polymerized chip is mixed with about 1 to 15% by weight of the mica powder in a hopper. The mixing in the mixing hopper is performed by mechanical means such as propellers by dissolving the raw material polymer chip and then injecting metal fine particles. In this case, the mica fine particles used are nano-scale powder powder having a purity of 99% or more having an average particle size of about 1 to 300 nm. At this time, by rotating the raw material to be evenly distributed metal particles in the polymer chip.

Fully mixed raw materials in the mixing hopper can be made into chips and used after drying or immediately following the spinning process after mixing. The molten raw material passed through the spinning machine is produced through the nozzle to the filament fiber is completed through a process such as stretching, burning.

The natural mineral component, for example, mica, mixed in the polyester fiber in the same manner as described above has bactericidal power against various bacteria harmful to the human body, which can prevent the growth of bacteria and odor caused by sweat generated during exercise. Radiation can help to promote metabolism, such as expansion of micro-vessels, promote blood circulation, activation of cell tissues, and give health-promoting effects.

In addition, the structural yarn constituting the surface layer supplies a nylon filament constituting a cross-sectional structure of a planar curve having a four-way protrusion having a single yarn fineness of 0.5 to 1 denier, a draw ratio of 2 to 3 times and a twist number of 600 to 800 (T / M) 40 to 43 Denia Lycra (Lycra) is prepared by double covering.

Nylon filament, the surface layer material, means a strand made of an aliphatic polyamide polymer. The nylon has an elliptical protrusion on the upper surface and the lower surface thereof, and has a circular protrusion on the left side and the right side thereof, that is, a planar curved cross-sectional structure having a four-way protrusion. One cross section of the nylon filament is shown in FIG. 3. The four-way uneven protrusions are formed to increase the voids between the fibers, and provide a passage for moisture due to the capillary phenomenon to speed up the movement of sweat and water, and to rapidly evaporate the transferred moisture with a large surface area.

Suitable nylons for the present invention include polyhexamethylene adipamide (nylon 66), polycaprolactam (nylon 6), polybutyrolactam (nylon 4), poly (9-aminononanoic acid) (nylon 9), poly Nantoractam (nylon 7), polycapryllactam (nylon 8) and polyhexamethylene sebacamide (nylon 6, 10). Preferred nylon is polyhexamethylene adipamide (nylon 66).

The nylon filament, which is the surface layer material, has a cross-sectional structure with excellent absorption quick-drying property, and is strong in abrasion and strong windproof property, and has an excellent thermal effect.

And, the nylon filament contains 1 to 20% by weight of activated carbon in the spinning process. Preferably the activated carbon component is to be contained 1 to 15% by weight based on the total fiber weight.

Activated carbon is a highly adsorptive and carbonaceous material of most constituents. The method of preparation is made by treating wood, lignite and peat with chemicals such as zinc chloride or phosphoric acid, which are activated, and drying or activating charcoal with water vapor. . Generally, activated carbon is manufactured in a powder state or a particle state, and powdered powder may be used in a particle state. Its use is mainly used to absorb gas and moisture as an adsorbent. In addition, it is used for various purposes such as solvent recovery agent and gas purification or decolorizing agent. In other words, activated carbon has micropores and a large surface area, so it is widely used as a deodorant generated in everyday life and to remove harmful gases generated in industrial sites.

The activated carbon component used in the present invention is a fibrous activated carbon, and the fibrous activated carbon is a carbon component manufactured by sintering with coconut shell, wood, and coal as a main raw material. The micropore is well developed and has a sufficient internal surface area. It is an aggregate of carbon and has excellent adsorption and deodorizing power. Most preferably, activated carbon made from palm bark is used.

The method of manufacturing the nylon fiber containing activated carbon is as follows.

About 85 to 99% of the raw material polymer chip is mixed with about 1 to 15% by weight of activated carbon powder in the hopper to prepare a polyester fiber including mica. Alkali weight loss then slightly dissolves the fiber surface to expose the activated carbon to the fiber surface. The fiber containing activated carbon thus produced may exhibit sufficient deodorizing performance only when 25 to 40% by weight of the total fabric weight is used.

Fibers having a double surface layer of the present invention have the property of stretching in four directions. The present invention has a dual structure of polyester having high thermal insulation by brushing nylon fibers with excellent elasticity, providing a soft texture and cosmetic function to the skin while being resistant to external contamination, wind, friction, etc., and elasticity by spandex In addition to granting four-way stretching by using shrinkage under the processing conditions, it is lighter than fiber woven by the method using a conventional spandex yarn, and is inexpensive and has excellent four-way elasticity while reducing defects such as dyeing and processing. Have

The four-way stretch fabric is connected to the knitting process rather than the method of bonding the different fabric layers can be knitted to omit the bonding process. As a bottom yarn, a nylon covering yarn is used, and PET yarn is used without covering the span to form a pile. After forming the bottom and pile with two kinds of yarns, the pile is blown to form a brush.

The spandex used in the covering company includes creora H-100, creora H-350, creora C-100, lycra, etc. Among them, lycra is most preferable in consideration of soft touch and weight, thickening, and dyeing processing conditions.

In order to give more elasticity, by using the elasticity and shrinkage of the knitted fabric itself in the processing step to have excellent elasticity in four directions. To make brushing happen well and make bulky, we used polyester yarn of triangular cross section. The length of brushing is 1 ~ 2mm and choose proper length to reduce the occurrence of peeling.

Conventionally, there are many stretch fabrics and some have four-way stretch fabrics, but in the case of thick fabrics that can be used as winter coats, there are few fabrics having sufficient stretch in four directions. Spandex yarns not only made the fabric heavy but also affected the dyeing and processing temperatures, making it difficult to produce good quality products. For example, in the case of winter climbing clothes on the market has a weight of 350 ~ 600g and it is necessary to reduce the weight to provide more comfortable conditions when wearing. That is, the present invention solves the problem of using a limited amount of span but needing to give more elasticity in the machining process.

If the high elastic fiber of the present invention is required, the antimicrobial composition of the present invention may be a deodorant (e.g., flavonoids, phytoncide, wood vinegar, plant extract, cyclodextrin, metal ions, titanium dioxide), anti-precipitation agent (e.g., polyvinyl alcohol (PVA). ), Pullulan, gellan, water soluble cellulose, glucan, xanthan, water soluble starch, levan) and the like. In addition, it may include well known fungicides, for example, antibacterial plant extracts, organic compounds and the like.

The present invention has a double surface structure of a back layer made of polyester fiber and a surface layer made of nylon fiber, which is excellent in heat retention and texture, and has high elasticity in four directions, as well as natural mineral components and Because it contains activated carbon, it has excellent antimicrobial, UV emission, absorption quick-drying and deodorizing properties. It can be usefully used for sports clothing and leisure clothing.

Hereinafter, the structure and effect of the present invention will be described in more detail with specific examples and comparative examples, but these examples are only intended to more clearly understand the present invention, and are not intended to limit the scope of the present invention.

Polyethylene terephthalate was used specifically among the kind of polyester. About 85 to 99% by weight of polyester yarn polymerized chips, about 1 to 15% by weight of the mica powder was mixed in a hopper. Mixing in a mixing hopper was performed by mechanical means such as propellers by dissolving the raw mica and then adding mica. As mica fine particles, nanoscale powder powder having a purity of 99% or more having an average particle size of about 1 to 300 nm was used. At this time, the raw material was rotated to evenly distribute the metal fine particles on the polymer chip.

After sufficient mixing in the mixing mixer, it immediately went through a spinning process. The molten raw material, which passed through the spinner, was made into fibers through filaments through a nozzle and completed through stretching, flamming, and the like.

The polyester fiber has the form of a triangular cross section (FIG. 2), and the single yarn fineness forms a single yarn fineness of 1 to 3 deniers. The muscovite was uniformly distributed in the fiber by the polyester fiber manufacturing step and the post-treatment step (FIG. 1).

(2) Preparation of Surface Layer of Nylon Fiber Containing Activated Carbon

The spinning solution in which polyhexamethylene adipamide (nylon 66) was melted was spun at a spinning speed of 2,500 m / min or more, a spinning temperature of 285 ° C., and a cooling wind speed of 0.4 m / sec. It extended | stretched at 85 degreeC and the heat setting temperature 130 degreeC, and obtained the nylon fiber of single yarn fineness 0.5-1 denier.

About 85 to 99% of the polyhexamethylene adipamide (nylon 66) raw material polymerization chip was mixed with about 1 to 15% by weight of activated carbon powder in the hopper to prepare a fiber.

Alkali weight loss then slightly melted the fiber surface to reveal the activated carbon on the fiber surface. The prepared carbon containing activated carbon may exhibit sufficient deodorization performance when 25 to 40% by weight of the total fabric weight is used.

By supplying the nylon filament with a single yarn fineness of 0.5 ~ 1 denia, a 40/70 nylon yarn was prepared by double-covering 40 denia Lycra with a draw ratio of 2 to 3 times and a twist number of 600 to 800 (T / M).

The four-way stretch fabric of the present invention was prepared in a way of directly connecting in the knitting process, not a method of bonding different fabric layers. That is, a separate bonding process can be omitted. Nylon covering was used as the bottom yarn, and PET yarn was used without covering the span to form a pile. Then, after forming the bottom and pile with the two types of yarn, the pile was popped to form a brush. At this time, the pile is formed in the same way as the conventional brushing method, and the loop is formed long in the fabric cutting process, and the ends of the loop are uniformly cut in the raising process to form a line on the fabric.

In the dyeing and processing process, the long axis minimizes the tension. The dyeing temperature range is 110-150 ℃ and the processing temperature range is 150-200 ℃. A 4-way stretch multifunctional fabric having a thickness of 1.5 mm and a weight of 240 g / sqm was obtained.
