Description

TECHNICAL FIELD The present invention relates to a high-conductivity textile-based amplifying antenna and a manufacturing method thereof.

The present invention relates to a high-conductivity textile-based amplifying antenna and a manufacturing method thereof, and more particularly, to a high-conductance textile-based amplifying antenna in which conductive ink is printed on textile and an amplifying antenna is formed by a printing method.

Recently, as the convergence of IT technology and clothing has accelerated, a smart wearable product in which electronic products, electronic circuits, or sensors are embedded in clothes has been released (refer to Patent No. 10-101235 and Patent Document 10-2014-0058502). However, this type of product is not only heavy but can also limit the wearer's activity.

In the United States and Europe, research is being conducted on technologies for constructing circuits in clothes themselves using conductive fibers. However, it is difficult to impart sufficient conductivity to the conductive fibers, and the conductivity is largely changed according to the elongation and shrinkage. Therefore, it is limited to be widely applied to general clothes due to complicated manufacturing process and high manufacturing cost (Park, Sung Kyu et al., Polymer Science and Technology Vol. 24, No. 1).

The inventors of the present invention have found that by forming an antenna pattern on a textile with conductive ink by a printing method, it is possible to provide a high-conductivity textile-based amplifying antenna having conductivity and antenna characteristics suitable for forming an antenna in a garment itself, .

The dyeing method of the fabrics can be divided into the dipping method and the printing method. Dyeing is a method of uniformly dyeing a fabric by immersing the fabric in a salt bath and applying heat to the fabric, and printing is performed by a dye composition (usually referred to as a "printing press") in which a dye or pigment is mixed with a thickener Quot; refers to a method of expressing a shape or color on a fabric by partially printing it.

Since printing can express various shapes and colors, various products can be produced according to the demand of the customer, and it is suitable for small quantity production of various kinds. In addition, the printing is carried out by a direct printing method in which the dyes are directly transferred to the fabric using a mold or a screen, the dye composition is kneaded in a desired shape on a transfer surface such as paper and the fabric is pressed on the knitted transfer surface, And transfer printing in which the dyes are dyed after post-treatment such as heat treatment and heat treatment. In the direct printing method, when a dye having an affinity with a fiber is used as a coloring material by hydrogen bonding, ionic bonding or the like, the dye is used as a dyeing intermediate medium, the dye composition is spun on a fabric, Is fixed to the fabric, and then the blank, unfixed dyestuffs, and other medicaments are cleaned and removed to obtain the final printed textile.

The thickener (thickener) serves to fix the dye or pigment to the fabric and to improve the color sharpness and the color development degree. When a suitable colorant is used, desired color can be obtained while reducing the amount of dye used. On the other hand, if an improper paste is used, problems such as contamination of fabrics after processing and deterioration of color sharpness may occur. That is, since the color sharpness and coloring degree of the fabric vary significantly depending on the used hose, it is very important to select an appropriate hose for efficient printing. It can be divided into natural and processed horticultural. Natural horticultural products include vegetable horticulture, animal horticultural and mineral horticultural, and processing horticultural horticultural and synthetic horticultural. Natural flour is a natural polymer such as sodium alginate, guar gum, starch, natural rubber, protein and seaweed. Semi-synthetic flour is mainly a natural polymer derivative such as processed starch, cellulose derivative and processed natural rubber. , Synthetic derivatives such as cellulose derivatives such as carboxymethyl cellulose (CMC), vinyl derivatives such as polyvinyl alcohol, acrylic derivatives, and urea-based foams. Natural foams and semi-synthetic foams are inexpensive but are not suitable for foams that require high salt resistance because of their low adhesion. In addition to this, a dye solubilizer for improving the solubility of the dye, an oxidizing agent for increasing the degree of dyeing of the dye, a defoaming agent for partially discoloring the dye to be dyed, a defoamer for removing bubbles generated during the working process, Such as preservatives, may also be used.

The dye composition used for printing is prepared by dissolving the dye, the foaming agent and the auxiliary agent in a solvent, and after the dye composition is printed on the fabric, the solvent is removed by heating. As the solvent used in the dye composition, an organic solvent or water may be used depending on the kind of the dye, the foaming agent and the auxiliary agent, but water is preferably used in consideration of workability and ease of wastewater treatment .

In recent years, inkjet prints have become available that enable computer-based printing techniques to be applied to dyeing technology to print dyestuffs on textile fabrics. As a result, it is possible to simplify the processing process and to produce a small quantity of various items by omitting steps of plate making and color matching which are required in the conventional printing technology, so that it is possible to respond quickly and to perform free color change and various designs more efficiently In addition, it is possible to increase the energy efficiency of dyes and formulations.

It is an object of the present invention to improve the productivity by constructing an amplifying antenna by constructing a circuit directly with a conductive ink on a textile and coating it through a printing method to construct an amplifying antenna.

To achieve these and other advantages and in accordance with the purpose of the present invention,

The present invention

fabric:

And an amplification pattern circuit formed on the fabric using conductive ink,

The conductive ink includes a silver-coated copper, a polyurethane resin, and a thickener, and provides a high-conductivity textile-based amplification antenna coated on the fabric in a printing method.

The silver-coated copper is preferably a dendritic type, and it is preferable to use silver containing 5 to 15 wt% of silver.

Here, the dendritic type can maintain high conductivity by connecting the branches of the resinous phase even when stretching. Specifically, the dendrite type has a particle size of 4-5 ㎛ compared to other particle sizes, and the surface area is twice as high (0.97 m ² / g) as the particle size of the same particle, and has high density in the resin phase and high conductivity in a small amount .

 The content of the silver-coated copper is preferably 30 to 50 parts by weight based on 100 parts by weight of the conductive ink.

The content of the polyurethane resin is preferably 50 to 70 parts by weight based on 100 parts by weight of the conductive ink.

The polyurethane resin is preferable for imparting stretchability and conductivity. Specifically, the polyurethane resin is not a thermosetting resin but is a plastic having a similar three-dimensional structure. However, it is used for an electric insulator, a structural material, a bubble insulation material, a bubble cushion, an elastic fiber and the like, . In the case of polyurethane resin, it has a low dependency on the environment while maintaining conductivity, excellent in deformation and strength, and is excellent in the production of conductive connection composition.

The content of the silver-coated copper and the polyurethane resin is an optimum condition for imparting conductivity and stretchability of the fabric by the printing coating. When the content of the silver-coated copper and the polyurethane resin exceeds the above range, Rather than increasing the cost of the product, and the economic burden due to rising costs. In addition, when the high-conductivity textile is manufactured, the elasticity is lowered and electrical short-circuiting occurs. If it is lower than the above-mentioned range, it may have a problem that the conductivity is remarkably deteriorated when the high-conductivity textile is produced with excellent stretchability.

The thickener may be an acrylic thickener or a urethane thickener.

The content of the thickener is preferably 0.5 to 2 parts by weight based on 100 parts by weight of the conductive ink.

Here, the content of the thickener is an optimum condition for printing coating, conductivity and stretchability. When the content of the thickener exceeds the above range, the viscosity of the thickener is high. Thus, the silk screen mesh can not be partially passed during the printing process, In case of lower than the above range, the silk screen mesh passes through the silk screen mesh well during the printing process because of low viscosity. However, since the silk screen mesh is not stable after passing, it may have a fundamental problem in producing the desired high- have.

The fabric may be any type of fabric that can be used as a garment, and may be made of elastic fibers (spandex, lycra, elastane, etc.) having molecular chains having urethane bonds occupying 85% or more of the chemical structure constituting the fibers. Or a stretched fabric selected from the group consisting of a fabric incorporating a PET, PTT, and PBT pottery stock, a fabric incorporating a yarn in which the shrinkage component is co-spun, and a stretchable nonwoven fabric.

In the amplification antenna, the pattern shape can be various shapes, and the frequency is determined according to the shape, and the shape can determine the function. For example, a spiral pattern can produce an optimal frequency that increases cell phone reception sensitivity. In addition, patterns can be formed to suit the functions of the company logo, stripes, special textiles, etc. on the fabric.

In addition,

(S1) mixing the coated copper with a polyurethane resin;

(S2) mixing a thickener with the mixture prepared in the step (S1) to prepare a conductive ink;

Fabricating a mask film for forming an amplification pattern circuit (S3);

(S4) attaching the mask film to the fabric and printing-coating the conductive ink with the conductive ink; And

Drying the printed fabric (S5);

The present invention provides a method for manufacturing a high-conductivity-fiber-based amplifying antenna.

In step S1, the silver-coated copper is preferably a dendritic type, and it is preferable to use silver containing 5 to 15 wt% of silver.

 The content of the silver-coated copper is preferably 30 to 50 parts by weight based on 100 parts by weight of the conductive ink.

 The content of the polyurethane resin is preferably 50 to 70 parts by weight based on 100 parts by weight of the conductive ink.

In step S2, the content of the polyurethane thickener is preferably 0.5 to 2 parts by weight based on 100 parts by weight of the conductive ink, and 0.5 to 2% by weight based on the polyurethane resin is preferably mixed.

In the above steps S1 and S2, it is preferable to mix the silver-coated copper with the polyurethane resin, stir the mixture, add a thickener, stir again, and then store at room temperature to stabilize the mixed solution.

In step S3, the fabric may be any type of fabric that can be used as a garment, and elastic fibers (e.g., spandex, lycra, elastane, etc.) having molecular chains having urethane bonds occupying 85% or more of the chemical structure constituting the fibers Or a stretchable fabric selected from the group consisting of stretchable nonwoven fabrics, or a fabric incorporating a PET, PTT, or PBT based potting stock, or a fabric incorporating a yarn in which the shrinkage component is co-extruded, and an elastic nonwoven fabric.

In step S3, the shape of the pattern of the antenna may be various, and the frequency is determined according to the shape, and the shape can determine the function. For example, a spiral pattern can produce an optimal frequency that increases cell phone reception sensitivity. In addition, patterns can be formed to suit the functions of the company logo, stripes, special textiles, etc. on the fabric.

In step S3, the film is a general plastic film, and preferably transparent like an OHP film. Almost any material that can be punctured by a laser is possible because the film is made by cutting the desired shape with a laser. However, if it is processed not smoothly, such as forming beads at the interface by melting in a laser, it is difficult to use it in a printing coating.

 Here, the amount of film used and the pattern forming method are required to be three if the target of screen printing is three degrees (three types of colors or patterns). After attaching the first film to the fabric, the first printing is done, then the second film is reattached after drying, the second printing is done, and the third printing is performed after drying again, so that various patterns and colors can be displayed have. Depending on the viscosity, it is also possible to coat the low viscosity polyurethane resin first and then coat the high viscosity polyurethane resin again.

In the step S4, it is preferable that the coating is coated by a printing method after attaching a film having a pattern to be coated to a fabric.

Here, the printing coating process can be carried out as follows. For example, in screen printing, a net is stretched with silk or nylon, the four corners are tightly fixed, and a valve is formed in a desired image by a hydraulic or photochemical method thereon, When the inner surface of the screen is pressed and moved by a spatula called "ink", the ink passes through the mesh of the portion without the valve, and is printed out on the fabric placed under the plate. When the ink is injected into the upper part of the printing net in a state where the hole of the pattern part to be printed is in an open state and the other holes are closed, when the ink is pressed by a squeegee, See Patent Document 10-2009-0052487).

In step S5, the drying is preferably performed at 50 to 70 ° C for 30 minutes to 2 hours or at room temperature for 2 hours to 4 hours, preferably at 60 ° C for 30 minutes or at room temperature for 2 hours or more.

Hereinafter, preferred embodiments and test examples of the present invention will be described in detail.

The embodiments, test examples, and drawings described in this specification are preferred embodiments of the present invention and do not represent all the technical ideas of the present invention, so that there are various equivalents and modifications that can be substituted at the time of the present application .
