The present invention relates to an electrically conductive fabric, and more particularly to a heat generating fabric and a method for producing the same.
Smart wear was devised so that digital functions can be used anytime, anywhere by applying a new technology of signal transduction fiber to fashion products using fibers and incorporating various digital devices. It is a new kind of product. That is, it is a new kind of garment that retains the attributes of the fiber or garment and has the necessary digital functions mounted on the fiber material and garment. For that purpose, it is necessary to transmit a digital signal while having the same tactile sensation and physical characteristics as a general fabric. Therefore, it can be said that it is a general term for a new concept garment that combines the high functionality of a material in which the fiber or garment itself senses an external stimulus and the fiber or garment itself reacts with the digital function that the garment and the fabric itself do not have.
Smartwear, which began to be developed for military use in the United States and Europe in the mid-1990s, is currently the most actively developed in the clothing and medical fields.

Therefore, technological development and product development of Flexible Print Fabric Circuit Board (FPFCB) by developing and applying electrically conductive materials are required.
That is, as a technology for developing a woven fabric capable of transmitting data by printing an electrically conductive substance on a woven fabric, a development of an electrically conductive material having excellent durability, a development of a technology capable of printing a conductive substance on a woven fabric, Development of circuit construction technology for woven fabrics and post-processing technology for maintaining and improving the performance of printed conductive materials are required.

Hereinafter, a desirable embodiment of the present invention will be described in detail with reference to the accompanying drawings of the present invention, but the present invention is not limited to these examples.
In the drawings, the same components or parts are designated by the same reference numerals as much as possible. Further, in the description of the present invention, specific description of related known functions or configurations will be omitted in order to clarify the gist of the present invention.
The terms "about", "substantially", etc. as used herein are used as the numerical value or a meaning close to the numerical value when the manufacturing and material tolerances specific to the referred meaning are presented. It is used to prevent unreasonable use by unconscionable infringers of disclosures that have been made and reference accurate or absolute numbers for the understanding of the present invention.
As used herein, "fabric" is used to mean all articles, non-woven fabrics, fibrous webs, etc. manufactured by weaving or knitting.
1 to 3 are cross-sectional views of the fabric according to a desirable embodiment of the present invention.
As shown in FIGS. 1 to 3, the heat generating fabric 10 according to the present invention can be composed of a base layer 100, a selective primer layer 200, a heat generating layer 300, a conductive layer 400, and an insulating layer 500.
In a fabric according to a preferred embodiment of the present invention, the base layer 100 may be any form of woven, knitted, non-woven or fibrous web. It can be applied without limitation to its material and forming method, and is composed of, for example, synthetic fibers such as polyester / polyamide / polyurethane, cellulose regenerated fibers such as rayon / acetate, and natural fibers such as cotton / wool.
The surface of the base layer 100 is very non-uniform when viewed microscopically, and there are an extremely large number of fine pores due to the gaps between the fibers. Therefore, the base layer 100 is ensured to ensure the uniformity of the surface and to form the heat generating layer and / or the conductive layer described later with a uniform thickness so that the substance forming the heat generating layer and the like does not permeate the back surface of the base layer 100. The primer layer 200 can be formed on the upper part of the. However, it means that the primer layer can be selectively formed on the fabric, and it is needless to say that the primer layer can be excluded depending on the characteristics of the fabric.
The primer layer 200 is one or more selected from the group consisting of polyurethane-based resins, acrylic-based resins, silicon-based resins, and the like.
On the other hand, the primer layer 200 according to the present invention can be formed by a single layer made of the above-mentioned substance, and can be formed by a multi-layer structure together with a water-repellent layer (not shown). The water repellent layer can be formed by a general water repellent treatment method, and is made of a fluorine or silicon material as a non-limiting example. The water repellent layer can be formed on the front surface and / or the back surface on which the heat generating layer and / or the conductive layer is formed. This has an advantage that the phenomenon that the resin component constituting the heat generating layer and / or the conductive layer permeates into the fabric in the manufacturing process can be prevented.
A heat generating layer 300 is formed on the upper part of the primer layer 200. The heating layer 300 can be formed by applying a conductive substance or a mixture of a conductive substance and a binder in a pre-designed form, wherein the conductive substance is polyaniline, polypyrrole, polythiophene, or the like as a polymer. Conductive carbon black can be mixed. It is also one or more selected from the group consisting of carbon, silver, gold, platinum, palladium, copper, aluminum, tin, iron and nickel.
FIG. 1 is a diagram showing an embodiment in which the conductive layer 400 is formed on the upper part of the heat generating layer 300, and the conductive layer 400 is a part of the upper part or the lower part of the heat generating layer 300 formed in a predesigned form. Is formed in.
On the other hand, FIG. 2 is a diagram showing another embodiment in which the conductive layer 400 is formed on the same plane as the heat generating layer 300, and the conductive layer 400 is formed in the same pattern as the heat generating layer 300 or another pattern. ..
Further, FIG. 3 is a diagram showing another embodiment in which the conductive layer 400 is formed under the heat generating layer 300.
The material constituting the conductive layer 400 is a metallic substance such as a conductive polymer, carbon, or silver, or a mixture of the substance and a binder, specifically, a conductive filler dispersed in a medium, and after printing. The cured film refers to a material having conductivity, and is usually used for LCD electrode printing, touch screen printing, energization pattern printing of circuit boards, contact parts and pattern parts printing of thin film switch plates, and electromagnetic wave shielding. Among the conductive metals (silver, gold, platinum, palladium, copper, nickel, etc.), the conductive filler is preferably silver-based.
The material of the binder of the conductive layer is one or more selected from the group consisting of polyurethane-based resin, acrylic-based resin, silicon-based resin, melamine-based resin, and epoxy-based resin.
On the other hand, it is desirable that the metal substance and the binder are mixed at a ratio of 90:10 to 80:20 (weight basis), but if the binder exceeds the above range, there is a problem that the conduction function is deteriorated. If it is less than the range of, there is a drawback that the adhesive strength is lowered.
The thickness of the heat generating layer 300 and / or the conductive layer 400 is preferably 2 to 500 μm, but if it is less than the above range, there is a problem that it is difficult to secure the thickness uniformity of the conductive layer. If it exceeds, there is a problem that the resistance value decreases and the current value increases under the same voltage, and eventually the power consumption increases. Further, the width of the conductive layer 400 is preferably about 10 to 20 mm, and as the width of the conductive layer increases, the resistance value decreases and the current is stably applied. However, if the width of the conductive layer increases indefinitely, the manufacturing cost and There is a problem with coverage. On the other hand, it is desirable to maintain the resistance value difference between before and after washing of the fabric according to the present invention of 0.5 to 4Ω, but if it is less than the above range, it is practically difficult to realize, and if it exceeds the above range, the current is stable. There is a problem with energization.
An insulating layer 500 is formed on the heating layer 300 and / or the conductive layer 400. The insulating layer 500 is coated, printed or laminated with one or more selected from the group consisting of polyurethane resin, acrylic resin, silicon resin, polyester resin, PVC resin and polytetrafluoroethylene (PTFE) resin. Can be formed by. The insulating layer 500 can prevent crack-like damage to the conductive layer, impart flexibility to the fabric, and perform a breathable waterproof or waterproof function.
Hereinafter, a method for producing a heat-generating fabric according to a desirable embodiment of the present invention will be described.
4 and 5 are manufacturing process diagrams showing a method for manufacturing a heat-generating fabric according to a desirable embodiment of the present invention.
As described above, once the fabric forming the base layer 100 is ready, the base layer fabric is supplied between the two squeezing rollers to compensate for defects such as surface irregularities in the case of woven or knitted fabrics. As a result, the surface of the base layer 100 becomes smooth, the voids of the base layer 100 are filled, and the bending resistance can be complemented (calendering step). This calendering step is a process that can be selectively performed according to the characteristics of the fabric.
The fabric with the base layer that has undergone or does not calender through the calendering steps more aggressively controls the surface voids and forms the primer layer 200 for the thickness uniformity of the conductive layer 300 and / or the conductive layer 400. can do. The primer layer 200 can be formed by a knife roller method, an overroll coating, a floating knife coating, or a knife overcoating, laminating, printing or gravure coating (primer layer forming step). As described above, the primer layer can also be selectively formed.
On the other hand, the primer layer can be formed of a multi-layer structure together with the water-repellent layer, and the step of forming the water-repellent layer can be carried out before or after the calendering step. The process diagram of FIG. 4 illustrates the step of forming the water repellent layer before the calendering step, and the process diagram of FIG. 5 illustrates the step of forming the water repellent layer and / or the primer layer after the calendering step. Is illustrated, but it is not limited to this.
A heating layer 300 and / or a conductive layer 400 is formed on the fabric on which the primer layer 200 is formed or the base layer is provided, in a pre-designed form. Various methods such as coating, printing, and transfer printing are applied to the coating method of the heat generating layer 300 and / or the conductive layer 400. In a desirable embodiment of the present invention, a method of forming the heating layer 300 and / or the conductive layer 400 by printing will be described as an example. In the case of the printing method, there is no limitation on the mounting position of the electronic device used, and the circuit can be designed on the fabric according to the designed form.
From this point of view, the fabric according to the present invention can be referred to as a Flexible Printed Fabric Circuit Board (FPFCB).
The pattern formation of the printed circuit board is designed so that the width and length of the lead wire, thereby determining the heat generation pattern, and measuring the resistance value for each heating element.
FIG. 6 is a diagram showing an example in which a conductive layer and a heat generating layer are formed on a fabric according to an embodiment of the present invention, in which the folded portion 430 is relatively wider than the linear circuit 410 in the circuit pattern of the conductive layer 400. It is a figure which shows the example which was formed in the wide shape 450. In FIG. 6, a circular shape is illustrated as the shape, but the shape is not limited to this, and if the shape is wider than the width of the linear circuit, other shapes such as a circular shape and an elliptical shape can be used. Of course, it can be adopted.
It is more desirable to form the bent portion 430 into a relatively wide shape, and the reason is supported by the following equation.
W = I<sup>2</sup>R R = ρ L / S W: power, R: resistance, ρ: resistivity, L: wire length, S: cross-sectional area
According to the above equation, the resistance decreases as the area increases, and at the same time, the current flow increases. Therefore, since the bent portion 430 basically has a wide shape 450, it becomes a factor for increasing the amount of current.
If the bent portion 430 of the lead wire has a right-angled or angular shape, a surge phenomenon may occur due to an unexpected change in the current flow, and an exothermic reaction may occur.
The surge phenomenon refers to an excessive waveform of electric current, voltage, or electric power transmitted along an electric wire or an electric circuit and having a characteristic of rapidly increasing and gradually decreasing in a short period of time. It is a major cause of power outages on lightning days, which can lead to telephone interruptions or the destruction of sensitive semiconductors. Sudden overvoltage on the power line, especially if the surge is strong or long, may cause dielectric breakdown or damage to electronic devices. Therefore, by installing a surge protector or surge suppressor between the power supply terminal and the computer terminal. , Suppress or minimize changes in current.
Therefore, in the present invention, the resistance value is lowered by changing the area of the bent portion 430, the occurrence of the surge phenomenon is minimized, and the current flows smoothly even if the amount of current increases.
It is desirable that the heat generating layer 300 and / or the conductive layer 400 maintain a thickness of 2 to 500 μm, a width of 10 to 20 mm, and a resistance value difference of 0.5 to 4 Ω before and after washing the fabric. Further, in the electrode, when carbon is used, it is 1 to 30% by weight, and when silver is used, it is 1 to 70% by weight. The binder that can be used for the heat generating layer and / or the conductive layer is one or more selected from the group consisting of polyurethane resin, acrylic resin, silicon resin, melamine resin, and epoxy resin that are compatible with the prime layer 200. (The heating layer formation step and / or the conduction layer formation step).
After the heating layer 300 and / or the conductive layer 400 is formed, the insulating layer 500 can be formed on the heating layer 300 and / or the conductive layer 400. The insulating layer 500 is directly coated with one or more selected from the group consisting of polyurethane-based resin, polyurethane-based resin, acrylic-based resin, silicon-based resin, polyester-based resin, and polytetrafluoroethylene (PTFE) -based resin. It can be formed by laminating. In the case of the coating method, a drying method is preferable, and in the case of a laminating method, a hot melt type dot method or a gravure method is preferable (insulation layer forming step).
In the insulating layer forming step, in the case of the coating method, the resistance value changes depending on the coating composition, which may affect the durability.
Further, the insulating layer can be formed not only on a single surface but also on both surfaces.
Therefore, considering that the characteristics of the fabric require several washings, the selection of a coating composition for causing a long-term insulation phenomenon, that is, for exhibiting excellent washing resistance, is an important factor. Is.
On the other hand, after the calendering step, the fabric that selectively constitutes the base layer 100 can be subjected to a moisture permeable waterproofing process or a waterproofing process. The pores formed by moisture permeable waterproofing or waterproofing not only fill the voids of the fabric that constitutes the base layer, but also serve to complement insulation, washing resistance, and bending resistance. It is desirable to apply a resin compatible with the conductive material as the substance used for the moisture permeable waterproofing process (moisture permeable waterproof / waterproof step).
This will be specifically described with reference to the following examples.

Was even bigger. It was also confirmed that the resistance after coating increased further and the rate of change in resistance also increased in the case of both sides rather than one side. On the other hand, in the case of liquid silicone rubber (Example 25), the resistance decreased in the case of single-sided coating, but increased slightly in the case of double-sided coating.</p><p> 2. Tensile strength: KSK0520 The elongation and tensile strength of Examples and Comparative Examples were repeatedly measured three times to obtain the average value. At this time, the grip interval was 76 mm, the tensile speed was 5 mm / min, the load was 1 KN (100 kgf), the temperature was 73 F, and the humidity was 50%. Table 3 below shows the test results of each example and comparative example.</p><p><tables num="3"><img file="JP2010513084A_D0004.tif" /></tables></p><p> FIGS. 7 to 10 are graphs showing changes in tensile strength and elongation according to the type of binder, and FIG. 7 shows the tensile strength at the time of silicon / polyurethane coating according to the type of binder added to the conductive substance. It is a diagram showing the change, FIG. 8 is a diagram showing the change in elongation at the time of silicon / polyurethane coating depending on the type of binder added to the conductive substance, and FIG. 9 is a diagram showing the heat generation pattern by the silicon single / double-sided coating. It is a figure which shows the tensile strength of the fabric with and without printing, and FIG. 10 is a figure which shows the elongation of the fabric with and without printing of the heat generation pattern by silicon single / double-sided coating. In the graph above, "untreated" means that the heat generation pattern is printed and no coating treatment is applied, and "Silicon C / T" means that the heat generation pattern is printed and single-sided coating treatment is performed with a silicone resin. "" Means that the heat generation pattern is printed and treated with a single-sided coating with a polyurethane resin, "PU-A" means a polyurethane binder, and "AC-A" means an acrylic binder.</p><p> From the above graph, it was found that when the polyurethane-based binder was added, the heat generation pattern coated with polyurethane was similar in tensile strength to the heat generation pattern without coating treatment, but the tensile strength decreased when coated with silicon. Was observed. It was also observed that when the acrylic binder was added, the tensile strength increased after coating, and when treated with the polyurethane coating rather than the silicon coating, the tensile strength was higher.</p><p> On the other hand, the change in elongation increases the elongation after coating regardless of the type of binder, which can be judged to be an increase in flexibility.</p><p> In relation to FIGS. 9 and 10, "printing of heat generation pattern X" means that the conductive polymer and electrodes are not printed and only coating treatment is performed, and "printing of heat generation pattern O" means that the conductive polymer is printed. It means that the electrodes (including acrylic binder) and the electrodes were printed and coated, but when the heat generation pattern was printed in both the single-sided coating and the double-sided coating, the tensile strength decreased. It was. This means that the fabric can be cut even by a weak force due to the printing of the heat generation pattern, and it can be judged that the fabric is more easily cut during the double-sided coating than the single-sided coating. In the case of elongation, it increased during double-sided coating rather than single-sided coating, and decreased when the heat generation pattern was printed.</p><p> 3. Bending resistance: (KS K 0855: 2004, C method (Crumple / Flex method)) After sewing a rectangular coated woven fabric into a cylindrical shape, both ends are gripped on two opposing discs to make a cylindrical test piece. After that, one disc is twisted 90 degrees, and at the same time, the other disc is reciprocated in the axial direction to bend the test piece, and the twisting and compressing motions are continued 1,000 times, 5,000 times, and 10,000 times. , The resistance was measured.</p><p> In order to investigate the durability when worn on clothes, the resistance difference between the heating layer and / the conductive layer after the bending resistance test by the printing procedure of the heating layer and the conductive layer was examined, and the resistance difference between the insulating layer before coating and that before coating was examined.
