Abstract
Description
TECHNICAL FIELD The present invention relates to a fiber including a carbon compound, an iron oxide compound, and a metal oxide component, and a photothermographic composition for a fabric, wherein the fiber and the fabric are made of fibers and fabrics so that the fiber and the fabric can be self- To < / RTI >
In the field of textile products, there has been researches for the interest and technology development of new materials with added functionality and sensibility according to the changing demands of consumers, and it has been applied for many years, There is a growing interest in new fiber materials that are easy to tame and do not get bored easily.
In recent years, there has been a growing interest in thermal and heat-generating materials in the field of heat insulation by thermal insulation, which has led to a shift from the conventional warming concept to a more aggressive thermal processing concept Is underway.
Methods for improving the heat-generating and thermal storage effect of a textile product include chemical or physical processing applied to the textile or clothing fabric that usually constitutes clothing to reflect the heat generated by the human body back to the human body, Adding heat storage function by applying ceramics or far-infrared rays to synthetic fiber products and giving heat storage function to the fiber aggregate by a combination of several factors and controlling heating, convection, radiation mechanism which is the movement path of heat And the like are proposed.
A method of improving the heat-retaining effect of a textile product is usually performed by changing the fabric structure of clothes or physically forming a large number of air layers inside clothes such as fibers made of hollow or porous material, Thereby reducing the heat dissipation generated by the heat dissipation member.
In addition, as a general application method applicable to general fibers, there is a method of blocking heat transfer by coating a non-breathable resin on the surface of a fabric, a method of confining air having a low thermal conductivity in a multi-layered fabric or fiber, A method of absorbing moisture to absorb heat, a method of absorbing sunlight to convert a part of solar light into heat, a method of absorbing moisture to absorb moisture, a hydrophilic carboxy group constituting fibers, a method of absorbing moisture, , A method of allowing a fiber material to generate heat under specific conditions, a method of using a special battery, a method of utilizing heat generated when iron is in contact with oxygen in the air, and the like, Or can be used only for a limited time and has a low durability.
In addition, there has been disclosed a technique for controlling the shape of a discharge port of a polymer material in a fiber production process and a heat insulating material utilizing a cross-sectional material or a cermet material prepared through an elongation control technique. However, There is a disadvantage in that the continuity of heat generation and insulation is deteriorated due to deformation of the cross section and unevenness of the fineness.
In addition, the cloth used in the garment expresses various colors by adding dyestuffs or pigments to most of the fabrics. In addition, functionalities are imparted to the methods of expressing colors, so that colors change according to changes in temperature or light, A photochromic pigment or a thermochromic pigment is applied.
Such a photosensitive or thermochromic coloring pigment generally exhibits a functional property by applying and fixing a discoloring pigment to a fabric. However, such a method has problems in that the touch of the fabric is rough and the discoloring pigment is easily separated from the fabric and the durability and the fastness There is a problem.
As a method for imparting various functions such as heat generation, heat storage, keeping warm, antibacterial, deodorizing, sensitizing or thermochromic discoloring, there has been proposed a method of imparting functionality by adding functional particles to the yarn during spinning or post- The method of melt-mixing the functional particles in the resin stream is advantageous in that the functional particles are chemically bonded with the resin of the fiber and thus the washing fastness is excellent. However, these functional particles act as a factor for breaking the yarn in the spinning process, The content of the functional particles in the spinning liquid can not be limited to a certain level, so that there is a limit to imparting functionality to the clothes in the above-described manner.
In addition, since the post-processing method is not limited by the content of the functional particles, there is no difficulty in imparting functionality to the fibers, but the durability and various fastnesses are still insufficient in many cases, so that the functionalities imparted by such post-processing methods are inevitably limited in terms of efficacy.
In order to solve such a problem, a method of mixing ceramic fine particles such as alumina-based, zirconium-based, and magnesia-based fibers into the fiber itself and using a function of converting far infrared rays emitted from the inorganic fine particles or converting the light into heat, Is positively introduced into the fibers.
As such a method, Korean Patent Registration No. 0337267 discloses a process for producing a ceramic material comprising 0.3 to 10% by weight of a ceramic filler belonging to Group 4 of the periodic table and 1 to 15% by weight of a conductive material such as carbon, nickel, copper sulfide, A ceramic material having a high far-infrared ray emissivity has a characteristic of absorbing near-infrared rays upon receiving sunlight, storing heat as heat energy, and reflecting heat from the human body, and thus, Has the advantage that the ease of use is equal to that of ordinary fibers and the energy source is permanent because the fiber itself is responsible for attracting the sunlight energy to the inside.
However, when the ceramic material having a high far infrared ray emissivity is mixed into the fiber as described above, if the content of the ceramic filler is low, the desired warming property can not be obtained. If the content of the conductive material is low, the static electricity generated by the ceramic material can not be removed. If the content of these components is high, there is a problem that the radiation workability is deteriorated.
In addition, Korean Patent Laid-Open Publication No. 1990-0003442 discloses a method for producing a ceramic solution by mixing a polypropylene solution with a conductive powder such as carbon powder to prepare a dendritic conductive material solution, adding a urethane or acrylic solution to the ceramic powder, There is disclosed a method of producing a conductive heat generating fiber in which a composite solution obtained by mixing a conductive material solution and a ceramics solution is impregnated with a fiber yarn or a fiber product to cause the composite solution to penetrate into the fiber structure and then an insulating solution is applied to the surface.
The present invention can be expected to have a beneficial effect on the human body since heat generated by the conductive powder and generation of the far-infrared rays by the ceramic powder are simultaneously provided and the far infrared rays are generated simultaneously with the heating. However, there is a limit to penetration of the composite solution into the fibers, If the composite is thinly coated and easily exfoliated from the yarn or fiber product, if the heat and the far-infrared ray effect are insufficient and applied to a large thickness, there is a problem that other functionalities such as flexibility and lightness of the fiber yarn or fiber product are deteriorated.
As another method, there has been proposed a method of positively preventing heat dissipation by depositing or coating a metal such as aluminum or titanium on the lining of a garment and reflecting radiant heat from the body on the metal deposition surface.
As such a method, Korean Patent Registration No. 1253032 discloses a method of dispersing at least one carbon material selected from the group consisting of carbon fibers, carbon nanofibers, and carbon nanotubes in water, an organic solvent, or a mixture thereof, Or a method of manufacturing functional fibers and fabrics that impart heat, heat, and heat storage functions to fibers or fabrics by applying them to a fabric by spraying, dipping, spraying or transferring and then drying.
The functional fibers and fabrics of the present invention coat a very small amount of carbon material on the fibers or fabrics so that the fibers or fabrics have a function of heating, maintaining and storing heat in a simple and economical manner. By using a small amount of carbon material, The problem of low durability and fastness according to the method can be solved to some extent, but this is not a solution to fundamentally solve the problem of the post-processing method. To add the antimicrobial function thereto, Durability and fastness are again questionable.
For example, Korean Patent Publication No. 1321017 discloses a method for imparting visual function to a fiber product in addition to a heat function. For example, Korean Patent Publication No. 1321017 discloses a method of manufacturing a carbon nanotube Heat-fusible fiber sheet which is coated with a heat-sensitive discoloring pigment and is applied to a non-heat-generating portion which is not overlapped with the heat-generating portion.
The present invention utilizes the excellent thermal properties of carbon nanotubes to absorb light such as sunlight to convert heat energy, thereby obtaining a heating effect and maximizing the functionality of the fabric by making it possible to obtain a color change effect of the heat-discoloring pigment .
However, the thermochromic pigment of the fiber sheet is attached to the fabric by dyeing or coating method, and the carbon nanotubes are attached to the fabric by a coating method such as printing or laminating. Since the thermochromic pigment does not dissolve in the solvent, There is a disadvantage that it is easily removed from the fabric.
As a solution to this problem, Korean Patent Laid-Open Publication No. 2013-0008904 discloses a method of manufacturing a light-shading composition by mixing rubber, a photochromic pigment, a binder, an inorganic or organic pigment on one side of a fabric, We tried to solve the problem that the photographic light was easily separated from the fabric by manufacturing the visualized fabric by printing on the fabric.
However, the above-mentioned invention improves the durability by attaching the visual photographic material to the fabric by using an acrylic resin, a polyester resin, an epoxy resin, a urethane resin or the like. However, since this method stiffens the fabric and lowers the flexibility, there is a problem.
A problem to be solved by the present invention is to provide a fiber and a photothermic composition for a fabric which allows a material capable of efficiently generating heat by light to be added to the fibers so that the fibers and the fabric are heated by only sunlight without a separate heating device.
In order to solve the above-described problems, the present invention provides a process for producing a spherical particles, which comprises 100 parts by weight of a carbon compound, 50 to 80 parts by weight of an iron oxide compound having spherical particles of 0.5 or more spherical particles, and 30 to 50 parts by weight of a metal oxide, 100 < RTI ID = 0.0 > pm, < / RTI >
At this time, the carbon compound is at least any one selected from the group consisting of carbon black, charcoal powder, carbon powder, graphite powder, carbon fiber powder, carbon nanotube and graphite, and the iron oxide compound is at least one selected from the group consisting of ferrous oxide, Iron, and the metal oxide is at least one selected from the group consisting of aluminum oxide, calcium oxide, zinc oxide, magnesium oxide, tin oxide, and oxidized transition metal.
It is also preferable that each particle constituting the composition has a uniform size with a standard deviation of 7 or less.
Preferably, the composition further comprises 10 to 30 parts by weight of at least one fourth periodic transition metal selected from the group consisting of titanium, chromium, manganese, nickel, copper and zinc based on 100 parts by weight of carbon compounds, The transition metal is more preferably a transition metal oxide sintered body having a uniform size with a particle size of 10 nm to 100 占 퐉 and a standard deviation of 7 or less or a transition metal sintered at 1000 to 1200 占 폚 in the presence of oxygen.
Preferably, the composition further comprises 1 to 10 parts by weight of a thermosensitive pigment, a photosensitive pigment or a mixed pigment thereof based on 100 parts by weight of the carbon compound.
Since the heat generating composition according to the present invention generates heat by sunlight itself, it can be applied to fibers and fabrics, so that the fibers and fabrics can exert heat and thermal insulation effects without a separate heating device, The fibers and fabrics containing them also exhibit antimicrobial activity.
In addition, even if the fiber and the fabric are not separately dyed, the color changes due to the heat due to the sunlight, thereby realizing a visual effect, and the problem of low durability and fastness according to the post-processing method is solved, A coloring effect can be provided.
The present invention relates to a photothermographic composition comprising a carbon compound, an iron oxide compound and a metal oxide, which is applied to a fiber or a fabric so that the fiber or fabric can obtain a heating effect only by light irradiation without a separate heating device.
The light generating composition may be a carbon compound of carbon black, charcoal powder, carbon powder, graphite powder, carbon fiber powder, carbon nanotube, graphene or a mixture thereof; Oxidation of ferrous stable form (FeO), ferric oxide (Fe 2 O 3), sasanhwasam iron (Fe 3 O 4) or the iron oxide compound in the mixture; And aluminum oxide (Al 2 O 3), calcium oxide (CaO), zinc oxide (ZnO), magnesium oxide (MgO), oxidation stannous (SnO), the oxidizing agent yijuseok (SnO 2) or a mixture of metal oxides; including And has a particle size of not more than a certain size, so that it can generate heat uniformly and rapidly by light.
Therefore, when the above-mentioned composition is used as a fiber, the fibers themselves can generate heat by light without a separate heating device, and since the composition particles that provide a heating effect have antibacterial activity, the fibers and fabrics containing them also exhibit antibacterial properties.
Specifically, the photothermogenic composition is composed of 50 to 80 parts by weight of an iron oxide compound and 30 to 50 parts by weight of a metal oxide in 100 parts by weight of a carbon compound, and these compositions may be contained in 1 to 10% by weight, have.
The carbon compound has a property of absorbing light and a property of storing heat, and the iron oxide compound has a particle size of a certain size or less. When light is irradiated, the iron oxide compound is uniformly heated And can be rapidly heated.
The metal oxide is heated to a very high temperature when light radiated from sunlight or fluorescent lamp, particularly light with a short wavelength, is irradiated on the surface, and such a high temperature is used for burning and decomposing organic substances and germs adhering to the surface of the metal oxide, , And the metal oxide itself acts as a catalyst for decomposing harmful substances and bacteria, thereby providing an antibacterial effect on the fibers and fabrics containing them.
In the present invention, the optimum wavelength range at which the light generating composition can generate heat is an electromagnetic wave having a frequency in the range of 300 MHz to 300 kHz (wavelength 1 m to 1 m), and includes infrared rays, far infrared rays, microwaves, Energy is absorbed by the carbon particles of the carbon compound to generate heat, and microwave energy is absorbed by the iron oxide compound and the metal oxide to generate heat.
Microwaves having a frequency between 300 MHz and 300 GHz induce molecular motion and ion conduction of the dielectric to generate heat. In the case of water, the change in the electric field of water molecules (electric dipoles) is slower than the change in microwave electric field, So that the vibrating heat is generated and heated.
On the other hand, although metals can not be used for heating because they reflect most of the microwave, polar materials such as ferric oxide, ferric oxide and iron tetraoxide are appropriately mixed and distributed with the ceramic material of the metal oxide, When microwave is irradiated to the ferrous oxide, ferric oxide and iron (III) oxide particles and metal oxide particles of polarity which exist in such a stable form, the microwave penetrates into the non-conductive iron oxide compound while the particles are vibrated, Heat is generated.
Since the photothermographic composition of the present invention has the characteristics of an intermediate semiconductor between a conductor and a non-conductor, absorption heating and induction heating are performed, and internal long wavelength waves are transmitted according to the charged state.
In other words, when a long-wavelength wave is applied to a continuous spherical carbon compound, iron oxide compound, or metal oxide particle, the iron oxide compound and the metal oxide particle are rapidly and stably heated by light, Is delivered along the surface of the successive particles to induce heating to induce a heating effect on adjacent particles.
For example, microwaves used in microwave ovens have long wavelengths that are widely used in everyday life. In this case, microwaves have a power of 0.2 to 3 kW at a frequency of 2.45 GHz.
When the fiber and the fabric including the photothermographic composition of the present invention are irradiated at 2.45 GHz corresponding to the frequency of the microwave oven, the temperature may rise to 10 ° C or higher in about one minute. Depending on the temperature raising rate and range The conditions can be changed according to the specific use.
The absorption heating effect is more effective as the particle size of the iron oxide compound and the metal oxide particle is smaller and the induction heating effect is more effective as the particle size of the adjacent particles is similar. Therefore, in order to increase the absorption heating effect and the induction heating effect, It is preferable that the particle size of the metal oxide particles have a similar size to each other within a range of 10 nm to 100 탆 and more preferably have a uniform size of 7 or less standard deviation.
Generally, since the penetration depth of the microwave to the metal oxide-containing material is several tens times larger than that of water, the energy of the microwave can penetrate deeply into the metal oxide-containing material.
However, if the thickness of the material is thinner than the penetration depth, only a part of the energy of the supplied microwaves is absorbed by the material, and the unabsorbed energy can not be used to pass through the material but if the material contains ferrous oxide, ferric oxide and titanium tetraoxide The unabsorbed energy can be reflected by the metal ions and absorbed by the metal oxide containing material again.
At this time, if the shape of the iron oxide compound particles has a shape of a square, an acicular, an irregular, a plate, a polygon or the like, the reflectance is low and energy loss occurs. Therefore, in order to uniformly reflect the microwave, The spherical shape is more preferable and the sphericity is more preferably 0.5 or more.
The sphericity is a measure of how close the sphere is to the shape of the particle, which means the ratio of the shortest side diameter to the longest side diameter of the particle. If the sphericity is less than 0.5, As a result, the microwave is converged to the tip of the particle edge to cause a spark, and the reflectance of the microwave is high at a spherical degree of 0.5 or more and the oscillation of the particle by the microwave is active, so that the heating and absorption heating effect is increased.
The iron oxide compound can be obtained from magnetite powder, hematite powder, iron ore powder, steelmaking slag powder, copper smelting slag powder, zinc smelting slag powder, red mud powder, fly ash powder, loess powder, , Bentonite, montmorillonite, ferrite, magnetite, pegmatite, tourmaline, sericite, loess and the like, but is not limited thereto.
In order to further improve the exothermic effect and heating effect of the light generating composition, the composition may further include a transition metal, and it may further comprise 10 to 30 parts by weight of transition metal based on 100 parts by weight of the carbon compound.
Transition metals are elements belonging to groups 3 to 12 in the periodic table and contain incomplete d, f orbital, metallic luster, and have the function of absorbing and storing light with electrical and thermal conductivity.
Preferably, the transition metal is a fourth periodic transition metal on the periodic table such as titanium, chromium, manganese, nickel, copper, and zinc, and the transition metal is a transition metal oxide sintered body sintered at 1000 to 1200 ° C in the presence of oxygen. desirable.
The fourth periodic transition metal is a state in which the electrons in the 3d orbitals are completely filled with electrons from 1s to 3p and 4s orbitals, and the electrons of the transition metals are 3d orbitals with low energy. Absorbing the visible light rays at the time of transition and exhibiting various colors, various colors can be expressed on the fibers depending on the type of the transition metal contained in the light emitting composition.
In addition, the sintered body of the fourth periodic transition metal oxide has a high emissivity and radiant energy in the far-infrared region and emits far-infrared rays due to the heat generated by the light generation of the composition in addition to the absorption and storage functions of the transition metal. A warming effect that warms the human body can be obtained.
The smaller the particle size of the transition metal particles is, the larger the absorption heating effect becomes, and the larger the similarity of particle size to the adjacent particles, the larger the induction heating effect. Therefore, the particle size of the transition metal particles is also in the range of 10 nm- It is preferable that the particles have a uniform size within a range of 100 mu m and a standard deviation of 7 or less.
The photothermographic composition of the present invention may further include a temperature sensitive and / or photosensitive pigment so that various colors can be expressed by the change of light. The thermochromic pigment, the photochromic pigment, And 1 to 10 parts by weight of a mixed pigment thereof.
The thermochromic pigment reversibly changes the chemical structure of the material according to the temperature change and changes the color accordingly. The photosensitive pigment exhibits a reversible color change due to the chemical structure of the material reversibly upon irradiation of light.
The thermo-sensitive pigment is composed of two components, an electron-donating substance and an electron-accepting substance. Examples of the electron-donating substance include triphenylmethane, fluorene, and roiminolactam. Examples of the electron-accepting substance include bisphenols , An alkyl phenol, a novolak type phenol resin, a carboxylic acid derivative and a metal salt, a hydroxybenzoic acid ester, an activated clay and the like can be used. When electrons move between an electron donor material and an electron accepting material, Color is not expressed.
The light-sensitive pigment is a pigment that emits light at the intensity of light or at a constant wavelength of light. Examples of the pigment include spironaphthooxazine, spiropyran, spirobenzopyran, spiroxazine, azobenzene azobenzene, formazan, fulgide, naphthopyran, chromen, diarylethene, and the like may be used. When absorbed, the structure of the compound is changed to color, and when the light is blocked, it is returned to the original compound structure and is discolored.
The thermochromic pigment and the light-sensitive pigment are usually encapsulated in microcapsules having a protective film and processed into a powder form, and melamine resin, epoxy resin, urethane resin, polyurea resin, polyester resin, polyvinyl chloride resin, polyvinyl An alcohol resin, an acrylic resin, a cellulose resin, or the like.
In general, the temperature-sensitive pigment is changed to a dark color when the ambient temperature is lowered and absorbs a lot of heat. When the temperature rises, it changes to a bright color to emit heat, and the light-sensitive pigment has various colors in succession The color change can be expressed most actively in the electromagnetic wave in the range of 789 ~ 3000 인 (wavelength 100 ~ 380 ㎚) which is the frequency band of ultraviolet ray.
The thermochromic pigment and the photosensitive pigment may be used alone or in combination to exhibit various colors. The thermochromic pigment and the photosensitive pigment themselves have a property of absorbing heat to impart heat storage effect, The color change is promoted by the heat generation of the carbon compound, the iron oxide compound, and the metal oxide of the light emitting composition, so that the color of the fiber is more clearly expressed.
The light emitting composition may be applied to a fiber so that the fiber exhibits an exothermic effect, an antibacterial effect and a coloring effect. The fabric or the fabric to which the light exothermic composition is applied may be a natural fiber, Synthetic fiber, semi-synthetic fiber, regenerated fiber, and the like.
There is no particular limitation on the method of applying the light exothermic composition to fibers or fabrics. For example, the composition may be mixed with a spinning solution for spinning the fiber, or the composition may be dissolved, dispersed or suspended in water or an organic solvent Followed by spraying, spraying, dipping, applying or transferring the fiber or fabric, and drying.
As the organic solvent, alcohol, acetone, ketone, ether and the like may be used. In order to improve the fiber adhesion of the composition, a metal alkoxide-based coupling agent may be added to water or an organic solvent. Increasing the interfacial adhesion between the fabric and the composition and increasing the adhesion between the two.
The metal alkoxide coupling agent may be an alkoxide of a metal selected from the group consisting of magnesium, aluminum, calcium and tin. Since the metal alkoxide includes the same element as the metal oxide, the metal / alkoxide- Or combine the fabric with the composition.
The content of the metal alkoxide coupling agent is preferably 0.2 to 2.0% by weight of the light exothermic composition. If the content of the metal alkoxide coupling agent is less than 0.2% by weight, the bonding between the fiber or the fabric and the composition is insufficient, By weight, and when it exceeds 2.0% by weight, the content of the composition is relatively decreased, which causes a problem that the exothermic property and the coloring property are lowered.
Since the composition is composed of fine particles and is excellent in adhesion to fibers or fabric, it can be added in a post-processing manner, so that heat, antibacterial and coloring functions can be imparted to fibers or fabric in a simple and economical manner.
The composition acting as described above can be applied to fibers, textile products, and fiber fabrics so that it can generate heat by itself without a separate heating device, so that it can be used for fabrics, knitted fabrics, nonwoven fabrics, clothing, thermal insulation, outdoor, hunting, It can be used for various applications requiring heat, heat, antibacterial or coloring effect such as ski suit, shoes, climbing tool, tent, quilt, bedding, mattress, greenhouse, greenhouse, Not only can energy saving replace existing insulation equipment, but it also has the advantage of keeping energy conservation while reducing energy use such as electricity and oil even in case of severe cold.
Hereinafter, the present invention will be described in more detail with reference to the following examples, comparative examples and test examples.
It is to be understood, however, that the invention is not to be construed as being limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. Will be apparent to those skilled in the art to which the present invention pertains.
≪ Examples 1 to 4 and Comparative Examples 1 and 2 >
Hereinafter, the light generating composition according to the present invention is coated on the surface of a fiber, and then the light is irradiated and the temperature change is measured to confirm the heat generating effect.
A photothermographic composition was prepared in the composition ratios shown in Table 1, and then 10 kg of the photothermal composition prepared above and 0.1 kg of an aluminum ethoxide coupling agent were mixed with 100 kg of methanol to prepare a coating solution.
A polyethylene terephthalate fiber having a fineness of 50 deniers was immersed in the coating solution for 10 minutes, followed by dewatering and drying, followed by washing with water and drying again to prepare a fiber in which the photothermographic composition was coated on the fiber surface in an amount of 5% by weight.

≪ Test Example 1 >
The fiber was cooled to room temperature and the fiber temperature was adjusted to 20 ° C. The fiber was irradiated with microwave (frequency 2.45 ㎓, output 2 ㎾) and ultraviolet (frequency 2000 ㎔, output 2 ㎾) For 1 minute, and then the temperature was measured. The results are shown in Table 2 below.
For comparative evaluation, the temperature was measured in the same manner as above using a polyethylene terephthalate fiber of 50 denier in size, which had not been coated with the light emitting composition, as a control group.
(° C)
As a result, the temperature of the control fiber, which is a general fiber, was not significantly changed even after irradiating microwave, but the fiber of the example according to the present invention showed a remarkably higher temperature than that of the conventional fiber not coated with the photothermographic composition. It can be seen that the light emitting composition coated on the surface is heated by irradiation of microwave and ultraviolet rays to generate heat.
Example 2 in which the thermochromic pigment and the photosensitive pigment were mixed showed a slight exothermic effect as compared with Example 1 in which the thermochromic pigment and the photosensitive pigment were mixed, so that the thermochromic pigment and the photosensitive pigment had a heating effect but were not so large.
Examples 3 and 4, in which a transition metal and a transition metal oxide sintered body are mixed, are superior in heat generation effect to Examples 1 and 2 in which they are not mixed, In Example 4, the exothermic effect was better than in Example 3 in which the heat-sensitive and light-sensitive pigment was not mixed. From these results, it was found that the transition metal was effective in light generation and the heat- .
Comparative Example 1 in which each component constituting the light emitting composition had a particle size exceeding 100 mu m had a lower light emitting effect and Comparative Example 2 with a lower sphericity showed the lowest light emitting effect, The light reflectance is lowered and the energy loss is generated. Therefore, it is understood that the light heating effect is lowered as the particle diameter of each component particle is larger.
As described above, when a photothermographic composition of a carbon compound, an iron oxide compound, and a metal oxide is coated on a surface of a fiber and irradiated with light, a heating effect of the fiber can be obtained by heat generation of the composition, It is understood that the size of each component particle is reduced and the transition metal or transition metal oxide sintered body is mixed to improve the heat generating effect.
≪ Test Example 2 > Measurement of color change effect
The light-generating compositions of the above-prepared examples and comparative examples were applied to a plain weave made of polyethylene terephthalate plain fibers having a fineness of 50 denier with a K-control coater (RK print Coat Instrument Ltd., UK) at 22 ± 1 g / after one surface coated with a coating amount of the m 2, it was dried for 30 seconds in a hot-air drier of 105 ℃ (YJ-8600D, Yujin Electronics, Korea).
Calendering was carried out using a supercalender (Supercalender, Beloit Corporatiom, USA) at a temperature of 70 DEG C and a pressure of 300 psi to prepare a fabric coated with the light exothermic composition.
The fabric was heated to 35 ° C. and the color change was observed. The fabric except for Examples 1 and 3 was purple at room temperature, but changed to white when it was heated to 35 ° C. After cooling to room temperature, Purple. The fabric was light purple in a dark place where the direct sunlight was not exposed, but exposed to direct sunlight, and the color became very fast.
That is, it is judged that the color changes from purple to white due to the effect of temperature-sensitive pigment by heating, the color of the color changes due to the action of the photosensitive pigment by light irradiation, and the color becomes darker when exposed to direct sunlight. It is considered that the color change effect of the photosensitive pigment by the light irradiation acts more.
Comparing the color change when irradiated with light, the change of the fabric of Comparative Example 2 was the most pronounced and the change of the fabric of Example 4 was the weakest. This shows that the heating effect of the fiber , It was estimated that the effect of changing the fabric of Example 4 to white of the thermosensitive pigment partially canceled the change of color of the photosensitive pigment. In Comparative Example 2, the color change effect of the thermosensitive pigment was small, .
As described above, it can be seen that the color of the fiber and the fabric can be variously adjusted by combining the carbon dioxide, the iron oxide compound and the metal oxide together with the thermosensitive pigment.
<Test Example 3> Measurement of antibacterial effect
The antibacterial and deodorization rates of the light-generating fibers of the above Examples and Comparative Examples were analyzed and the results are shown in Table 3 below.
The antimicrobial activity of Staphylococcus aureus ATCC 6538 and Klebsiella pneumoniae ATCC 4352) was measured by the method of KS K 0693: 2011, and the deodorization rate was measured at 30, 60, 90 and 120 minutes using the gas detection method for ammonia (NH 3 ) The gas concentration was measured at the elapsed time.
(Blank gas concentration-Sample gas concentration) / Blank gas concentration} x 100 (%) < tb > Head Col 2: Test gas concentration: 500 쨉 g /
As can be seen from the results of the above Table 3, the antibacterial degree shows a bacteriological reduction rate of 99.9% or more in both Examples and Comparative Examples. When a carbon compound, an iron oxide compound or a metal oxide is included, It showed sufficient antibacterial activity irrespective of its size and spherical shape.
In the case of the deodorization ratio, Comparative Example 1 having the largest particle size of the photothermographic composition exhibited the lowest result, and Comparative Example 2 having the small sphericity showed the highest deodorization rate. As the particle size became larger (Comparative Example 1) The surface area is reduced and the active area to deodorize the ammonia gas becomes smaller. When the sphericity is smaller (Comparative Example 2), the specific surface area becomes larger and the deodorization active area becomes larger.
Example 2, in which the sensitizing / photosensitive pigment was mixed and the transition metal component was not mixed, and Example 1 in which the sensitizing / photosensitive pigment was not mixed with the transition metal component, showed no significant difference, And Examples 3 and 4 in which the transition metal components are mixed show deodorization rates higher than those in Examples 1 and 2 in which the transition metal components are not mixed, so that the transition metal has a deodorizing ability .
Further, it can be seen that the deodorization rate gradually increases with time, and the smell is gradually removed by continuously decomposing ammonia. From the results, the antibacterial effect and deodorizing effect of the photothermal composition of the present invention can be confirmed.
