BACKGROUND ART Conventionally, in case of functional fabrics, functionality is a very important aspect. Further, most of the functional fabrics are developed to be made of synthetic fiber. Accordingly, the fabrics cannot sufficiently serve as fashionable materials.
Recently, raw yarns and cloths are developed to have functions such as high tenacity, antistatic, electric conductivity, flame resistance, antiflame activity, ultraviolet ray shielding, antimicrobial potency, stench resistance, moisture permeable water proof, soil resistance, moisture absorption, thermal insulation, thermal storage, stretch, etc.
There are several methods for imposing such functions to the raw yarns and cloths. More specifically, these methods include fibrosis of functional polymers (including inorganic compounds), copolymerization, and additive reaction of functional additives in a raw material preparation step, functionality addition in a spinning step, functionality addition in a yarn preparation step, functionality addition in a fabric making step, and functionality addition in a dyeing step.
Hereinafter, these methods classified in accordance with steps are shown in Table 1, as follows.

As shown in above Table 1, in case that functionality is imposed at each step of the raw material preparation step, spinning step, yam preparation step, fabric making step, and dyeing step, except for the case in which functionality is imposed at a processing step, materials for imposing functionality must be variously employed so as to maxima ! iy exhibit the imposed functions at the raw materiat preparation step, spinning step, yarn preparation step, fabric making step, and dyeing step and to manufacture fashionable products.
However, in case that functionality is imposed steps prior to the dyeing step, the used materials are mainly made of synthetic fiber. Thus, the use of the materials is limited and the fashionableness is reduced.
In order to produce a fashionable fabric, the used materials must be diversified, and thus standards and structures thereof must be diversified. However, since functional materials are made of only synthetic fibers, there is a limit in diversifying the resulted products.
Accordingly, the present invention provides a fabric obtained by arranging a function cloth at an intermediate layer and cotton or wool at both outer layers, thus sufficiently exhibiting functions and producing high-class and fashionable products.
For example, conventional fabrics having the high tenacity and moisture permeable water-proof functions are made of synthetic fibers, thus not being used as a fashionable purpose.
That is, a fabric used to produce a golf wind-shielding jumper (windscreen jumper) cannot be used to produce trousers or coats. Because the appearance and characteristics of the cloth of the fabric are different, the appearance, tactile sensation and material of the cloth must be differently changed in accordance with the purposes of the fabrics. The currently used functional synthetic fibers cannot satisfy this requirement.
Accordingly, there is required to a high-class fabric, which has the above various functions and is used as various purposes.
In view of the above problems, there are currently developed a fabric, in which a film is interposed between two conventional fabrics, and another fabric, in which a knitted goods is attached to a conventional fabric by an adhesive agent so as to have double sides, i. e., to have characteristics of woven goods at one side and characteristics of knitted goods at the other side.
However, the fabric obtained by using the above adhesive agent has not soft touch, and cannot exhibit the identified characteristics of a used material. Further, since a method for producing such a fabric requires an attaching step, the fabric has a
large thickness and an adhesive layer is easily separated from the material due to the use for a long period of time and the laundry.
Therefore, there is obtained a product with a low functionality and fashionableness.
DISCLOSURE OF THE INVENTION Therefore, the present invention has been made in view of the above problems, and it is an object of the present invention to provide a multi-layer fabric provided with a functional cloth having various functions such as moisture permeable water-proof, high-tenacity and/or electromagnetic wave shielding functions between cloth layers, and bound thereto by a bonding yarn, thus having fashionableness and multi-function in a small thickness.
BRIEF DESCRIPTION OF THE DRAWINGS The above and other objects, features and other advantages of the present invention will be more clearly understood from the following detailed description taken in conjunction with the accompanying drawings, in which: Fig. 1 is a schematic view of a fabric woven out of a cotton yarn; and Fig. 2 is a schematic view of a fabric woven out of a wool yarn.
BEST MODE FOR CARRYING OUT THE INVENTION Now, preferred embodiments of the present invention will be described in detail with reference to the annexed drawings.
The present invention discloses a multi-layer fabric, in which a functional cloth 2 having various functions such as electromagnetic wave and/or ultraviolet ray shielding, and the cloths 1, 2 and 3 are bound by a binding yarn 4, thus having
characteristics and functions of the cloths.
That is, as shown in Figs. 1, the cotton cloth 1 is made of a cotton material, the cloth 2 is made of a synthetic fiber filament yarn with a very thin diameter, and the cloth 3 is prepared. The cloths 1,2 and 3 are bound so as to produce a single fabric.
The functional cloth 2 is designed such that it has moisture permeable and water-proof, high tenacity, and electromagnetic wave shielding functions, etc. , thus serving as a multipurpose cloth having various functions and fashionableness.
Difference from the conventional adhesive cloth, the cloths 1,2 and 3 bound by the bonding yarn exhibit their identified material characteristics, structural characteristics, appearances and functional characteristics, thus having excellent fashionableness.
These cloths can be various used, easily cut, and not be separated due to the use for a long period of time and the laundry. Further, a fabric not requiring a lining material can be obtained in accordance with design standards of the intermediate functional cloth 2.
Hereinafter, functional cloths 2 having various purposes used as the intermediate layer are described in detail.
A moisture permeable and water-proof functional cloth ; It provides to a fabric a moisture permeable and water proof function, which transmits vapor through a fine porous film provided with holes with a diameter of 0. 2-1 O m smatter than the diameter (100-6, 000 m) of rain drop and bigger than the diameter (0.0004µm) of vapor, but does not transmit rain drop by means of surface tension, thereby shielding rain and wind and discharging sweat.
A high-tenacity functional cloth ; It is made of a high-tenacity yarn, thereby preventing a fabric from being torn and forming a film for protecting a skin.
An electromagnetic wave shielding functional cloth ;
Silver or copper is used to shield an electric wave, and metal such as iron is used to shield a magnetic wave. The above cloth is produced by plating a raw cloth with the above metal, sputtering the raw cloth, and mixing the raw cloth with a metal fiber, thereby reducing a coefficient of cubical resistance of the fiber and shielding electromagnetic waves.
An UV ray shielding function cloth ; It includes an UV ray scattering reflector and an UV ray absorber. The UV ray scattering reflector shields UV rays by the light reflection and scattering using superfine inorganic substances such as titan dioxide and zinc oxide. The UV ray absorber is an inorganic substance such as benzotriazole, benzophenol or salicylic acid-group substance, and uses as a processing agent a substance which absorbs UV rays, changes the absorbed UV rays into a lower energy state, and then eliminate the UV rays. Thereby, the above substances impose the UV ray shielding function to the cloth.
An antibacterial and stench resistant functional cloth ; It is obtained by attaching an antibacterial and stench resistant agent to a raw cloth so that bacteria giving out a bad smell are sterilized and suppressed, or by mixing silver, copper and/or titanium to a raw yarn via monomer improvement so that the bad smell is removed via a chemical smell eliminating reaction, thereby having the antibacterial and stench resistant function.
A flame resistant and anti-flame functional cloth ; It is obtained by copolymerizing an anti-flame agent to a substance in production of a polymer, mixing an anti-flame agent to a substance in production of a fiber, or providing an anti-flame agent to a fiber product (reacting the anti-flame agent to a main body of the fiber product or independently attaching the anti-flame agent to the fiber product), thereby having the anti-flame function, reducing the heat transmission speed by means of the heat-proof polymer and the toxic gas generation, and preventing
the melting of the fiber.
A warmth and thermal storage functional cloth ; It is obtained by mixing or coating a material containing the great amount of air with a low heat conductivity for preventing a heat loss by heat convection and conduction, a material containing metal for preventing a heat loss by heat radiation, a material having a ceramic adiabatic property or a far infrared ray function, or a material having a high warmth-keeping function using a solar heat by containing a metal carbide or oxide having light-absorbing and heat-accumulating property onto a raw cloth, thereby having the warmth-keeping function which does not eliminate heat discharged from the human body to the outside and the heat-accumulating function which absorbs solar light or heat from the outside and then transmits the absorbed light or heat to the inside.
A stretch functional cloth ; The cloth with an wrinkled appearance made of a processed elastic yarn obtained by heating a synthetic fiber filament yarn so as to have elasticity, or a processed elastic yarn obtained by coating a polyurethane or polyethylene elastic yarn with a covered yarn, a core span yarn, a fly yarn, or an air covered yarn is obtained by the difference of contractibility between respective layers.
An antistatic and electric conductive functional cloth ; It is obtained by processing the surface of a fiber or fiber product with a hydrophilic resin, or injecting a hydrophilic polymer to the fiber or fiber product in a <BR> <BR> <BR> polymerization and spinning step, thereby reducing the static electricity accumulation due to the reduction in surface electric resistance. The cloth is mixed with an electrification prevention fiber, an electrified fiber or a conductive fiber, thereby serving as means for scattering the static electricity and imposing the antistatic function to a fabric
A moisture absorption functional cloth ; It is obtained by being made of a fiber made a moisture absorption high molecular substance, by being made of a fiber including a hydrophilic compound mixed to a hydrophobic high molecular substance, or by grafting a hydrophilic compound to a hydrophobic synthetic fiber, thereby effectively absorbing sweat and rapidly discharging the absorbed sweat so that the sweat is swiftly evaporated. Accordingly, the cloth removes the sticking to the human body due to the sweat and improving comfortableness of a wearer.
A soil resistant functional cloth ; It is obtained by processing the surface of a fiber with a hydrocarbon, silicon or fluorine resin so that contaminants cannot be attached to the surface of the fiber, or by making the surface of a hydrophilic synthetic fiber to be hydrophilic so that contaminants attached to the surface are easily removed, or by employing the irregular reflection effect of a modified cross-section fiber so that contaminants attached to the surface are not easily shown, thereby being prevented from contaminating.
One of the above-described functional cloths is interposed between two cloths and connected to the cloths by a binding yarn, thereby being produced in a multi-layer fabric having functionality and probability to be developed as various fashionable fabrics TRIAL APPLICABILITY As apparent from the above description, the present invention provides a multi-layer fabric provided with a functional cloth having various functions such as moisture permeable water-proof, high-tenacity and/or electromagnetic wave shielding functions between cloth layers, and bound thereto by a bonding yarn, thus having fashionableness and multi-function in a small thickness.
Although the preferred embodiments of the present invention have been disclosed for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims.
