Description

A multi-functional textile consisting of two different layers}

The present invention forms a double-surface structure of a surface layer consisting of a back layer and a nylon-based fiber, which is composed of polyester fibers, it is characterized in that it contains the silver component and a seaweed extract component relates to a functional fiber.

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. However, in the case of the conventional spandex yarn, the mixing ratio between the other yarns is low, so that the sole property of the spandex is lost, so that the inherent physical properties are not exhibited. There is a limit to the application for sporting products that require.

In addition, the elastic fibers are caused by a lot of bacteria and fungi attached to the clothing by the various secretions discharged from the body, of which attach to the fabric does not harm the human body, but deteriorated, colored clothing In some cases, pollution can cause odors, and in some cases it can directly harm the human body. In particular, there are many cases in which elastic fibers are used as girdle and braser of women, but in this case, bacteria or fungi may inhabit the elastic fibers due to secretions caused by sweat or the like.

As a method for imparting antimicrobial properties, poly (pentane-1,5-carbonate) diol, poly (hexane-1,6-carbonate) diol, which is a polycarbonate diol type of aliphatic diol as a soft segment in US Pat. No. 4,837,292, or these A method for imparting antimicrobial properties by using a copolymer of is disclosed. This is a method of giving antimicrobial properties using the physical properties of the raw material itself without adding a separate antimicrobial agent, but there is a problem of low antibacterial effect.

Currently, silver (Ag) particles are used to produce textile products having an antibacterial effect. Silver (Ag) is known as a potent fungicide that kills bacteria by minimizing and incapacitating enzymes that act on the metabolic function of unicellular bacteria (TN Kim, QL Feng, et al. J. Mater. Sci. Mater. Med. , 9, 129 (1998). Silver-based inorganic antimicrobials currently in use are commercialized in the form of silver-supported inorganic powders, silver colloids, metal silver powders, etc. Among them, silver-supported inorganic powder forms the largest share in demand. It is this form. However, silver present in an ionic state has a good antibacterial activity, but due to its high reactivity, the state is unstable, so it is easily oxidized or reduced to metal depending on the surrounding atmosphere, which causes discoloration of itself or coloration of other materials, and thus has the disadvantage of low sustainability. On the other hand, silver in the form of metals or oxides is stable to the environment, but has a disadvantage of using a relatively large amount due to low antibacterial activity.

In addition, algae are generally classified by color, that is, they are classified as Chlorophycea, Phaeophyta, Rhodophyta, and Cyanophyta, which are vitamins, mineral salts, and antioxidants. It is rich in fixing pollutants, promoting removal, and stimulating metabolism due to iodine content and improving general body appearance, making it an interesting material for application to functional fibers.

However, in the case of the functional fiber produced by the conventional methods, the fiber having the antimicrobial and elasticity at the same time is not currently developed, and the elasticity decrease due to the decrease in viscosity by the inter-inorganic minerals when the antimicrobial agent is added in the elastic yarn manufacturing step Can not be avoided. In addition, it is possible to find a method of antimicrobial post-treatment processing on the stretchable yarn, but the problem of deterioration in washing durability and touch occurs, and the discoloration due to the high reactivity of silver also became a problem. Therefore, there is an urgent need in the art for the emergence of multifunctional fibers having excellent antimicrobial and elasticity, excellent absorbency and warmth, and which can be manufactured through a stable process.

It is an object of the present invention to provide a multi-surface multifunctional fiber having excellent four-way elasticity, antimicrobial activity, absorbency and warmth at the same time.

The present invention to achieve the above object, if that is composed of polyester fibers Seaweed extracts containing layer and composed of nylon-based fiber forms a double-surface structure of the surface layer, and expand and contract in four directions, the silver component Provides multifunctional fibers after-processing at 5-25% owf (on the weight of fiber or fabric).

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.

The term "fiber" in the present invention is meant to include all of the fiber raw material, fiber yarn and fiber fabric, the fiber material is a material of the fiber yarn, the fiber yarn (filament, thread, yarn, etc.) is a constituent material of the fiber fabric, Fibrous fabrics include products made from fibrous yarns, for example woven, knitted, felt, plated, braid, lace, nonwoven, laminated, molded fabrics, etc. do. In the present invention, the term "fiber" is used interchangeably with "fiber product". Textile products made from such fibers, such as garments (eg, underwear, sportswear, pajamas, casual, mountaineering, etc.); plant; Bedding; Shoe soles; carpet; towel; Curtains and the like are also included within the scope of the present invention.

As used herein, the term "elasticity" refers to elasticity. In other words, it refers to the property of returning to its original state when the external force is removed after stretching it by applying an external force to an elastic body. If the elastic body is in a four-phase state (nylon, polyester, polyurethane, etc.), it is called an elastic yarn. Once manufactured, they are classified as stretch fabrics.

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.

Hereinafter, the present invention will be described in detail.

In the present invention, by weaving into a structural yarn forming a functional double surface layer in order to exhibit the functionality of the four-way stretch fabric, the excellent function can be evenly expressed by the strong wear resistance and wind resistance of the surface layer, and the breathability, hygroscopicity, and heat retention of the back layer. Provide functional fibers.

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 the elliptic crimp must be formed by spandex alone, and the 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 applicable depending on the dyeing conditions, there is a limit to the application for sports products that require 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 also disclose a method of using polytrimethylene terephthalate (PTT) or polybutylene terephthalate (PBT) having stretch properties in polyethylene terephthalate (PET). Suggesting. As described above, the conventional methods for preparing stretchable composite fibers have only been 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 has a thick fabric cross-section and stretches only the surface layer to give the elasticity to the back layer at the same time, thereby reducing the content of the expensive span yarn, and the elastically moving portion close to the skin softly moves to the entire fabric. Compared to thick fabrics using spanners, they are more comfortable to wear, especially sports sportswear that requires sufficient activity while protecting the body.

Structural yarn constituting the back layer of the present invention is a monofilament polyester filament of a triangular cross section prepared by mixing the seaweed extract having a single yarn fineness of 1 to 3 denier, the pile yarn adjusted to the strength of the pile when brushed well .

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 of these.

The polyester filament of the triangular cross section of the back layer material may have a higher hair-stability compared to the general circular cross section yarns, and further increase the raising effect when raising the pile of the back layer formed of the polyester yarn. Fine fineness of the polyester pile yarn is softly adhered to the skin and has the effect of forming a capillary tube between the fibers in the shape of the fiber cross-section, so as to quickly absorb the sweat discharged by the exercise and to move to the surface layer quickly. Therefore, the napping layer is in close contact with the skin to quickly absorb the liquid sweat and transfer it to the surface layer.As a thick air layer is formed in the napping layer, it prevents a decrease in body temperature caused by the sweat of the liquid generated during exercise and cold weather. By protecting the body from the traditional winter clothing, while reducing the volume, the warming effect can be increased.

And, the polyester fiber contains seaweed extract during spinning.

Seaweed extract used in the present invention can be used without limitation, if the material that produces the desired effect of the green algae, brown algae, red algae, preferably using components extracted from brown algae.

Green algae contain large amounts of chlorophyll, which is active in photosynthesis to produce starch. The fronds of green algae have a very transparent green color, and the chromosome has a pigment called chloroplast, β-carotene (β-Caotene), and xanthophyll-based lutein (Lutein). Green algae live primarily in shallow waters, so leaf-like species grow in large quantities in relatively deep ocean beds.

Brown algae generally grow in deeper water than green algae and form a marine forest because of the large number of algae that are several meters long. Seaweed contains a lot of vitamin A, as in the case of Haitai or blue, and evenly contains other types of vitamins. Inorganic salts contain a lot of potassium and calcium, and a significant amount of iron. Kelp is also a highly alkaline food and nutrition is similar to seaweed. Seaweed and kelp, among other things, contain large amounts of alginic acid, a fiber that contributes greatly to the peristalsis of the large intestine, thus facilitating animal defecation. It is preferable to use the alginic acid as a component of the seaweed extract used in the present invention. Brown algae have chlorophylls (a) and (c) as photosynthetic pigments, and other pigments have various pigments, including β-carotene and fugoxanthin. The photosynthetic product is not stored in the form of starch, but in the form of laminarin or mannitol.

Red algae inhabit relatively deeper water than other algae, and are relatively small in size but diverse. Red algae have a wider range of habitat than green algae and brown algae, and grow from shallow water depths to deep water rays. Therefore, there are more species than other birds.

Among various seaweed extracts, alginate extracted from seaweed and kelp is alginate with high purity, which is free of impurities such as polyphenols, endotoxins, and proteins.

Alginic acid is a polysaccharide that constitutes the cell membrane of brown algae, also known as seaweed acid, and is a polymer of two kinds of uronic acid, which shows acid properties due to the carboxyl group of uronic acid. Its structure is hundreds of mannuronic acid and L-gluronic acid connected by β-1 and 4 bonds.

The alginic acid is a fiber of seaweed, which protects cells from harmful free radicals generated by the metabolism in the body and harmful oxygen generated by pollution, pollution, heavy metals, pesticides, food additives, synthetic drugs, and radiation. It also promotes the function of enzymes to remove harmful free radicals, thereby delaying aging and preventing skin blemishes and spots from occurring.

The seaweed extract is mixed about 2 to 10% by weight based on the weight of the fiber yarn during polyester spinning in the hopper. At this time, the seaweed extract used is nano-scale powder powder having a purity of 99% or more in which the average particle size is about 1 to 100 nm in the form of fine particles. The seaweed extract evenly distributed in the molten polyester is spun together with the polymer to form functional fibers in which the seaweed extract is uniformly distributed in the fiber through a process such as stretching and winding, which is a general polyester fiber manufacturing process. Even though polyester fiber containing seaweed extract is synthetic fiber, seaweed extract mixed in the fiber has high water retention, increasing moisture content of synthetic fiber, giving soft touch like natural fiber, moisturizing, skin protection, aging It provides functions such as prevention.

In addition, the structural yarn constituting the surface layer of the present invention supplies four-channel nylon filament having a single yarn fineness of 1 to 3 deniers, 40 to 43 denier lycra (Lycra) with a draw ratio of 2 to 3 times and a twisting ratio of 600 to 800 (T / M). ) Is manufactured by double covering.

The four-channel nylon filament of the surface layer material means a strand made of an aliphatic polyamide polymer. The nylon has an elliptical channel in the upper and lower surfaces, and has four channel structures forming a circular channel on the left and right surfaces. By forming the uneven protrusions by the four channels to increase the voids between the fibers, giving the movement path of water by the capillary phenomenon to speed up the movement of sweat and water, and has a large surface area to quickly evaporate the moisture.

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 four-layer 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 in windproof property, and has excellent thermal insulation effect.

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 which has high thermal insulation by nylon fiber with excellent elasticity and brushing, and provides a soft texture and cosmetic function to the skin while being resistant to external contamination, wind, friction, etc. In addition to providing elasticity, four-way stretching is applied by using shrinkage under processing conditions, and it is lighter than fiber woven by a method using a conventional spandex yarn, and it has a low price and excellent four-way elasticity while reducing defects such as dyeing and processing. Has

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 to have bulkiness, triangular polyester yarn was used. The brushing length is 1 ~ 5mm and the proper length is selected 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 the winter climbing clothes on the market has a weight of 350 ~ 600g, it is necessary to reduce the weight in order to provide more comfortable conditions when wearing. That is, the present invention solves the problem that the use of a limited amount of span and yarn, but the need to give more elasticity in the processing process and increase the heat retention.

In addition, the fiber of the present invention contains a silver nano component for antibacterial properties.

Regarding conventional polyester antimicrobial fibers, as disclosed in Japanese Patent Laid-Open Nos. 59-134418, 61-17567 and the like, a method of applying a metallic compound or a zirconia-containing liquid to the general-purpose polyester fibers by a spray method has been proposed. It was a problem. Meanwhile, Korean Patent Application No. 1992-0008832 proposes a method of mixing an inorganic antimicrobial agent with a liquid polyester type dispersant and inserting it into a spinning process. Japanese Patent Application Laid-Open No. 61-234390, 62-101643 and Korean Patent Application No. 1991-0014960, In 1990-0022031, 1990- 0022031, etc., a master batch chip was prepared using inorganic zeolite, oxide ceramic, porous alumina silicate, and silica / alumina subjected to high temperature calcining, and then mixed spinning, Although the manufacturing method is disclosed, it is difficult to secure the radioactivity during melt spinning due to the strong water absorption characteristics of the inorganic antimicrobial agent, the physical properties of the fiber due to the viscosity decrease, the pressure rise due to the inorganic fine particles, other color defects and difficulty in controlling the dispersibility are still problems. Remains. As for the nylon-based antimicrobial fibers, there are, for example, Japanese Patent Publication No. 87-184126, which is an antibacterial and deodorizing technique using quaternary ammonium salts, and US Patent No. 4,701,518, which is a method for producing antibacterial nylon fibers treated with zinc compounds. . The antimicrobial deodorant fibers by these methods have been found to have problems of detrimental resistance to the human body of quaternary ammonium salts added for the expression of antimicrobial properties and an absolute weakness of the post-processing method.

Therefore, the present inventors included a silver nano component to increase the antimicrobial properties of the fiber. Preferably, the silver nano component is treated with 5-25% o.w.f.

Silver nano is a compound word that combines nanotechnology and silver (Ag), which are technologies that deal with materials and devices at the nanometer level (Nanometer: 1nm = 1 billionth of a meter). Formed and grafted to a fine particle size, it refers to a solution in which the silver component of the ultra fine size is dispersed in a solvent such as distilled water.

This silver (Ag) has a more effective effect due to the emergence of nanotechnology, especially in the nano-state, the sterilization ability is changed qualitatively, and very small size nano silver (Ag) has a very strong sterilization action do. In addition, when the silver meets the water, the bactericidal and antimicrobial effects become stronger, thereby preventing the growth and propagation of bacteria and toxicity. The silver component is not only strong sterilizing and antibacterial, but also has effects such as odor removal, electromagnetic wave and ultraviolet ray blocking, far infrared rays and anion emission.

In the present invention, the following method may be used as one of the methods of containing the silver nanocomponent in the fiber. Of course, it may also be by conventional methods known in the art. Korean Unexamined Patent Publication No. 2002-0050902 describes an example in which metal nanoparticles are applied to synthetic fibers.

The silver nano has a particle average distribution of 5 to 50 nanometers and is immersed in a padding bath diluted 5-25% owf at a bath ratio of 1:10 with respect to the weight of the fabric of the double structure that has been dyed. After passing through the mangle and heat-treated at 120 ~ 150 ℃ it is contained in the fiber of the present invention.

The silver nano component of the present invention is electrodeless pure silver, the size of the nanoparticles is characterized in that the particle average of 5 to 50 nanometers. The electrodeless nano pure silver of the present invention does not oxidize and exhibits the effect of maintaining the color as it is.

Fiber containing silver nano generates good ions and far infrared rays in the body when it is used, and it stimulates blood circulation and endocrine activity. It blocks more than 90% of the form hormone, an environmental hormone, which is a problem recently. There are many advantages of vitamin B6 skin protection and deodorization effect and lasting sterilization effect for a long time.

It reacts sensitively according to the degree of pollution of the surrounding environment and shows continuous antiseptic action by destroying bacterial cell membranes or disturbing cell functions. Recent research shows that silver nano can sterilize 650 kinds of bacteria and viruses, and it is excellent in inhibiting the growth of harmful bacteria and microorganisms. Oxygen is converted into active oxygen to prevent sterilization, adsorption of heavy metals and bacterial growth.

In addition, silver nano is very easy to coat or mix with other materials, and the like is easily mixed or coated with the material of the fiber made of the poly-based synthetic resin of the present application.

If the stretchable multifunctional 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), precipitation inhibitor (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 composed of polyester fibers and a surface layer composed of nylon fibers, which not only has superior four-way elasticity, but also excellent water absorption and thermal insulation, and furthermore, a silver nano component. And it contains a seaweed extract component has a high antimicrobial power and fastness. In addition, it can also be usefully used in the bar, sports clothing, leisure clothing, underwear, etc. excellent in the touch by the process moisture content.

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.

The measuring method for measuring the performance of the multifunctional fiber having antibacterial, lightweight, sweat-absorbent quick-drying and heat insulation according to the present invention will be described first.

1) Elasticity of the fiber

The elasticity of the fiber was tested according to the method specified in KS K 0352.

2) Antimicrobial, Lightweight and Warmth:

Fabrics and / or knits were made from the fibers obtained according to examples or comparative examples. The antimicrobial, lightweight and warmth properties of the obtained fabrics were tested according to the methods defined in KS K 0693, KS K 0514 and KS K 0466, respectively.

3) Absorbent quick-drying: Water-drop test and drying time test were performed.

Example  One : Polyester  And Nylon  4-way stretching of the double surface structure of the fiber Multifunctional  Fabric manufacturer

(1) Backing layer of polyester fiber containing seaweed extract and surface layer weaving of nylon fiber

Polyethylene terephthalate was specifically used among the kinds of polyester, and about 2 to 10% by weight of alginic acid powder powder was mixed and melt-spun to about 90 to 98% by weight of polyester yarn polymerization chips based on the weight of the polyester fiber yarn. Seaweed fibers were prepared, and then, in the drawing process, the draw ratio and the degree of orientation were adjusted to make a pile yarn of weak strength. The polyester fiber had the form of a triangular cross section (FIG. 2), and the single yarn fineness formed a single yarn fineness of 1 to 3 deniers. At this time, the alginic acid powder is used nano-scale powder powder of 99% or more purity of the average particle size of about 1 ~ 100nm, the amount of the alginic acid is 2 ~ 10% of the weight of the polyester yarn.

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 the temperature of 85 degreeC, and the heat setting temperature of 130 degreeC, and obtained the nylon fiber of single yarn fineness of 0.5-1 denier. 40/70 nylon yarn was prepared by supplying four channels of nylon filaments having a single yarn fineness of 0.5 to 1 denier, and double covering 40 denia Lycra with a draw ratio of 2 to 3 times and a twist number of 600 to 800 (T / M).

(2) 4-way stretch multifunctional fabric weaving

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 was formed in the same way as the conventional brushing method, and the loop was formed long in the fabric cutting process, and the end of the loop was uniformly cut out in the process of raising the fabric to form a line on the fabric. At this time, the tension was minimized in the dyeing and processing process, the application temperature range was 110 ~ 150 ℃. In this manner, a fabric having a thickness of 1 to 3 mm and a weight of 200 to 250 g / sqm was obtained.

(3) silver nano processing

Silver nano was uniformly distributed in the fiber by the post-processing step after the polyester and nylon fiber layer manufacturing process and dyeing, brushing process and the like (Fig. 1).

 The silver nano has a particle average distribution of 5 to 50 nanometers and is immersed in a padding bath diluted 5-25% owf at a bath ratio of 1:10 with respect to the weight of the fabric of the double structure that has been dyed. After passing through the mangle and heat-treated at 120 ~ 150 ℃.

Comparative Example 1 Fabrication of Cotton- Spandex Blend Fabric

96% cotton 30% coma cotton fiber and 4% spandex knitted in a single tissue and not brushed fabric, weighing 244g per m ² and thickness of 0.8mm.

Comparative Example 2 Preparation of Polyester- Spandex Blend

70 denier DTY polyester fibers, 97% and 4% spandex yarn of a single (single) to the fabric are not knitted and brushed with tissue m ² weight per 172g, thickness consisting of filaments of polyethylene terephthalate 68 strands radiating melt polymerized chips 0.5 mm.

Comparative Example 3 Preparation of Polyester- Spandex Mixed Velvet Fabric

Velvet fabric knitted and brushed 93% of 70 denia polyester fiber and 7% spandex composed of 34 filaments melted and spun polyethylene terephthalate polymer chip was weight 370g per m ² , thickness 1.5mm.

Experimental Example  One : Polyester  And Nylon  4-way stretching of the double surface structure of the fiber Multifunctional Fabric  Elasticity rating

The stretch test results of the stretch fabrics obtained by the above Examples and Comparative Examples are shown in Table 1 below. The measuring method was tested according to the method specified in KS K 0352.

Elongation Example 1 Comparative Example 1 Comparative Example 2 Comparative Example 3 Width direction (%) 76 87 81 27 Axial direction (%) 70 69 50 13

As a result of the measurement, it had elasticity of 76 (%) in the width direction and 70 (%) in the axial direction. Comparative Examples 1 and 2 of the thin fabrics have elasticity similar to that of Example, but Example 1 has elasticity of 2 to 5 times or more compared to Comparative Example 3 having a thicker structure.

However, in comparison with Comparative Examples 1 and 2, Example 1 of the present invention uses polyester yarn, which is a stretch yarn only on the surface layer, to give elasticity to the back layer at the same time, thereby reducing expensive spanner content. In addition, the close portion close to the skin softly moved elastically has the advantage of improving the fit compared to the thick fabric using the span yarn throughout the fabric. In addition, it has higher elasticity in the width direction and the axial direction, and is more active than the high elastic material in only one direction.

Experimental Example  2 : Polyester  And Nylon  Thermal insulation evaluation of 4-way stretch multifunctional fabric with double surface structure of fiber

The results of the effective insulation ratio test for the two-layer fabric obtained by the above Examples and Comparative Examples are shown in Table 2 below. The measuring method was based on ASTM-D1518.

Thermal insulation evaluation Example 1 Comparative Example 1 Comparative Example 2 Comparative Example 3 Warmth retention (%) 43 14 9 22

From Table 2, it can be seen that heat retention is about 4 times higher than that of general span fabrics and about 2 times higher than brushed velvet fabrics.

Experimental Example  3: Polyester  And Nylon  4-way stretching of the double surface structure of the fiber Multifunctional Fabric  Absorbency Rating

Water-drop test was used to test the absorbency. This experiment was conducted at least 5 times from one yard of sample to the opposite side of the width. The absorbency was determined by measuring the time that the water droplets were completely absorbed by the fabric. Is shown in Table 3.

Thermal insulation evaluation Example 1 Comparative Example 1 Comparative Example 2 Comparative Example 3 Water absorption time 3.5 seconds 4.5 seconds 120 seconds or more 120 seconds or more

From Table 3, it was confirmed that the water droplets are completely absorbed at a faster time than cotton in Example 1 consisting of polyester yarn and nylon yarn, and Comparative Examples 2 and 3 made of general polyester yarn are knitted with hydrophobic fibers of polyester 120 Absorption is hardly achieved even in seconds or more, indicating that the absorbency is remarkably inferior.

Experimental Example  4 : Polyester  And Nylon  4-way stretching of the double surface structure of the fiber Multifunctional  Fabric Antimicrobial  evaluation

The antimicrobial test by KS K 0693 was carried out by the following method. Inoculation of Staphylococcus aureus and Staphylococcus aureus 2 Klebsiella pneumoniae was carried out in test specimens and control specimens, followed by incubation for a period of time. do.

As a result, as can be seen in Table 4, it showed the highest antimicrobial activity of 99.9%, even after washing 20 times or more was maintained at 99.9% antibacterial activity.

Experimental Example  5: Polyester  And Nylon  4-way stretching of the double surface structure of the fiber Multifunctional Fabric  fair Moisture content evaluation

Since the moisture content of the fiber varies depending on the air dry condition, the moisture standard at the time of commercial use is used. The moisture content of the fiber is determined based on the quantification of adding the moisture content to 100 parts per minute and adding the process moisture content to the dry amount. Process moisture content relative to oven dry weight is specified in KS K 0301.

In general, natural fibers have a high process moisture content and synthetic fibers have a low process moisture content. For example, it has a process moisture of 8.5% cotton, 12% hemp, 18.2% wool, 12% silk, 11% rayon, 4.5% nylon, and 0.4% polyester.

The moisture content of the polyester fiber including the seaweed extract of Example 1 was measured and in accordance with KS K 0220 standard. Weighing test specimens left at standard conditions for 24 hours or more, the test pieces were dried in an oven at 105 to 110 ° C. for about 1 hour, weighed again, and moisture content was calculated from the weight difference before and after drying. As a result, the polyester fiber of Example 1 had a process water content of 5 to 10%.

Therefore, the fabric of the present invention by the high moisture retention of the seaweed component, by increasing the process moisture content of the polyester fiber to 5 ~ 10% close to the moisture content of the natural fiber to further soften the feel close to the skin and skin cosmetic effect by the seaweed extract It has the effect of suppressing the generation of static electricity.
