Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a light emitting diode (LED)

The present invention relates to an apparatus for manufacturing a light emitting fabric and a method for manufacturing a light emitting fabric using the same.

Various reflectors having a light reflection function are used for a part where visibility is required, such as a sign of specific information or an indication of design, in a safety garment, a fire suit, a safety article, a sports garment, a shoe or other decorative article.

The above reflector is attached to a part of the clothes. It is troublesome to attach the reflector to the clothes, and it is difficult to exert a sufficient recognition function because it is attached only to a part of the clothes.

In order to solve the above problems, a recursive composition such as a light emitting material (dolphin material, phosphorescent material, etc.), glass bead, microprism or the like is applied to the fabric to form a light emitting layer.

However, due to the low processability of the composition, it is difficult to carry out the subsequent dyeing step or the reflection forming step due to the low workability of the glass beads or the microprism, and the problem of low fastness.

And the light emitting layer is formed by passing a base material between the first roller and the second roller so that a recycled composition adhered to the first roller is applied to one surface of the base material.

However, when the recycled composition was applied to one side of the substrate, some recycled composition passed through the substrate and became lodged on the second roller surface. The recycled composition adhered to the second roller was buried on the other side of the substrate, and some of the recycled composition passed through the substrate again to cause mixing with the composition on one side of the substrate. The light emitting layer formed on one side of the substrate was not elaborated by mixing the composition.

The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Like parts are designated with like reference numerals throughout the specification.

An apparatus for manufacturing a light emitting fabric according to an embodiment of the present invention will now be described with reference to FIGS. 1 to 5. FIG.

1, an apparatus 100 for manufacturing a light emitting fabric according to the present embodiment includes a preprocessing unit 20, a light emitting layer forming unit 30, a post-processing unit 40, and a transferring unit (not shown) A light emitting material 200 including the substrate 1, the base layer 2, the light emitting layer 3, and the protective layer 4 is produced.

Although the preprocessing unit 20, the light emitting layer forming unit 30, and the post-processing unit 40 are shown as being connected in series in FIG. 1, they may be arranged separately. The arrangement structure of the light emitting fabric manufacturing apparatus 100 may vary according to the design conditions of the light emitting fabric manufacturing apparatus 100.

The base layer 2, the light emitting layer 3 and the protective layer 4 are formed on one surface of the base material 1.

The base material (1) is not particularly limited and may be a synthetic fabric or a knitted fabric such as a natural fabric or a knitted fabric such as a fiber, a paper, a translucent, a cotton, a hemp, a dog or a wool, a nylon, a polyurethane, a polyester, have. Furthermore, the above listed materials may be transferred, printed, UV printed, solvent printed, aqueous printed, offset printed, and the like. The thickness of the substrate 1 is not particularly limited and can be suitably adjusted according to the use of the fabric.

2, the pretreatment unit 20 includes a first roller 21, a second roller 22, and a drying unit 23, and forms a base layer 2 on one side of the base material 1. The base layer 2 arranges one surface of the base material 1 so that the light-emitting layer 3 which proceeds to a subsequent process can be smoothly formed on the base material 1.

The first roller 21 and the second roller 22 can rotate in conjunction with each other. The base material 1 is inserted between the first roller 21 and the second roller 22 so that one side of the base material 1 contacts the first roller 21 and the other side of the base material 1 contacts the second roller 22.

The first roller 21 is provided with a life 21a uniformly buried with the pretreatment composition. The life 21a is disposed along the longitudinal direction of the first roller 21. [ The first roller 21 can apply the applied pretreatment composition to one side of the substrate 1. The second roller 22 supports the substrate 1 to which the pretreatment composition is applied.

The drying section 23 passes the base material 1 coated with the pretreatment composition and dries the pretreatment composition. The drying section 23 can dry the substrate 1 at a drying temperature of 60 ° C to 120 ° C.

The base layer 2 may be formed on one surface of the substrate 1 by drying the pretreatment composition. If the temperature of the drying section 23 exceeds 120 degrees, the base material 1 and the base layer 2 may be damaged, and if the temperature is less than 60 degrees, drying of the pretreatment composition may not be easy.

The detailed structure of the pretreatment unit 20 as described above can be applied to a pretreatment unit, a reflective fabric, and a manufacturing method thereof (patent registration No. 10-1322371) of a composite processing apparatus (patent registration No. 10-1423705) ) Can be applied, and a detailed description thereof will be omitted.

The base material 1 on which the base layer 2 is formed may be recovered on a separate roller or supplied to the light emitting layer forming portion 30. [

3, the light emitting layer forming unit 30 includes a first roller 31, a second roller 32, a drying unit 33, a supplying unit 34 and a collecting unit 35, The light emitting layer 3 is formed.

A base material 1 on which a base layer 2 is formed is supplied between the first roller 31 and the second roller 32. [ The drying section 33 passes the first roller 31 and the second roller 32 to dry the substrate 1 to which the recycled composition is applied.

The first roller 31, the second roller 32 and the drying unit 33 are the same as the first roller 21, the second roller 22 and the drying unit 23 of the pre-processing unit 20 Duplicate description will be omitted.

However, the light emitting composition may be adhered to the outer circumferential surface of the first roller 31 through the life 31a. The light emitting composition may be a recursive composition.

The supply part 34 and the recovery part 35 are spaced apart. The supply part (34) and the collecting part (35) are wound around a base fabric (50) in the form of a belt connected at both ends. The base fabric 50 can be continuously rotated while being wound around the supply part 34 and the recovery part 35. The base fabric 50 may be a nonwoven fabric. However, the supply unit 34 may supply the base fabric 50 and the recovery unit 35 may recover the base fabric 50 that has passed through the first roller 31 and the second roller 32.

The supply portion 34 is located in front of the second roller 32 and the recovery portion 35 faces the second roller 32 with the drying portion 33 therebetween. That is, the recovery unit 35 is located behind the drying unit 33 through which the base material 1 passed through the drying unit 33 is discharged. The base fabric 50 can then pass through the first roller 31, the second roller 32 and the drying section 33 together with the substrate 1 on which the base layer 2 is formed.

A recursive composition applied to the first roller 31 as the substrate 1 passes between the first roller 31 and the second roller 32 together with the base fabric 50 can be applied over the base layer 2 have. At this time, a part of the recursive composition is applied to the base fabric 50 while passing through the base material 1. It is possible to prevent the beads included in the reclaimed composition from being stuck on the surface of the second roller 32. In addition, it is possible to prevent the recursive composition from being stuck on the second roller 32. Therefore, it is possible to solve the conventional problem caused by the recycled composition being deposited on the second roller 32.

The base material 1 and the base fabric 50 to which the recursive composition is applied may pass through the drying portion 33 and the light emitting layer 3 may be formed on the base layer 2. [ The recycled composition deposited on the base fabric 50 may also be dried through the drying section 33.

The substrate 1 having passed through the drying unit 33 may be wound around a separate roller or may be immediately supplied to the post-treatment unit 40.

The base fabric 50 having passed through the drying section 33 may be supplied to the supply section 34 through the recovery section 35 and supplied to the space between the first roller 31 and the second roller 32. As the base fabric 50 passes through the drying section 33, the recycled composition adhered to the base fabric 50 may be dried.

4, the recovery unit 35 is disposed between the second roller 32 and the drying unit 33, as shown in FIG. 3, and the recovery unit 35 is disposed behind the drying unit 33. However, As shown in FIG. In this case, the base fabric 50 may be supplied to the supply roller 34 in front of the drying unit 33 without passing through the drying unit 33.

The luminous layer forming unit 30 may further include a luminous composition in addition to the recycled composition. The recursive composition and the phosphorescent composition may be used alone. However, a recursive composition can be applied on the base layer 2 and then dried to form a recurrent layer, and then the phosphorescent composition can be coated on the recycled layer and then dried to form a phosphorescent layer. However, the phosphorescent layer may be formed first, and the recurrent layer may be formed thereon. The light emitting layer may be formed of a recurrent layer and a phosphorescent layer. The recycled composition and the phosphorescent composition may also be mixed and applied simultaneously to the base layer. Accordingly, the recurrent layer and the phosphorescent layer can be formed as one layer.

The order of application of the recycled composition and the phosphorescent composition is not particularly limited. The recurrent layer and the phosphorescent layer may be superimposed on the base layer 2, or the luminous layer may be formed on the other side of the base layer 2 and the recurrent layer may be formed on the other side. When the recursive composition and the phosphorescent composition are mixed, the recurrent layer and the phosphorescent light-emitting layer can be formed simultaneously in one layer. The location and manner of the recurrent and phosphorescent layers can be varied.

5, the post-processing unit 40 includes a first roller 41, a second roller 42, and a drying unit 43 and applies a post-treatment composition on the light-emitting layer 3.

Since the first roller 41, the second roller 42 and the drying unit 43 are the same as the first roller 21, the second roller 22 and the drying unit 23 of the preprocessing unit 20, A description thereof will be omitted.

However, the post-treatment composition may be applied to the outer circumferential surface of the first roller 41 through the life 41a. The post-treatment composition is deposited and the post-treatment composition can be applied onto the light-emitting layer 3 through the first roller 41. [ The substrate 1 to which the post-treatment composition is applied may be a drying section 43 and the protective layer 4 may be formed on the light emitting layer 3. [

While the above description and drawings illustrate the application of the pretreatment composition, recycled composition and post treatment composition to the substrate in a roll manner, the manner of application of the composition may be reversed, gravure, comma coater, such as spray, slit coating, bar coating, or knife coating, or the like.

The transfer portion forms a transfer layer (not shown) on the base material 1. The transfer layer may be formed by heat transfer or sublimation transfer. The transfer layer is formed on the base layer. However, the transfer layer may be selectively formed on the base layer, the light-emitting layer or the protective layer.

The details of the transferring unit are as follows. The transferring unit, the reflecting cloth, and the manufacturing method thereof (Patent Registration No. 10-1322371) of the composite processing apparatus (patent registration No. 10-1423705) And the detailed description will be omitted.

Next, a method of manufacturing a light emitting fabric will be described.

Referring to FIGS. 1 to 6, a method of fabricating a light emitting device according to an embodiment of the present invention includes a base layer forming step S10, a light emitting layer forming step S20, a protective layer forming step S30 and a transfer layer forming step S40 .

When the unprocessed substrate 1 is supplied between the first roller 21 and the second roller 22 in the base layer forming step S10, the pretreatment composition adhered to the first roller 21 is transferred to one surface of the substrate 1 . ≪ / RTI >

 The pretreatment composition comprises 100 parts by weight of a solvent and 3 to 8 parts by weight of a water-soluble polyacrylic resin. In this case, the solvent is preferably a polar solvent, and any solvent selected from the group consisting of water, an alcohol having 1 to 5 carbon atoms, and a mixture thereof may be used.

In the water-soluble polyacrylic resin, An anionic functional group selected from the group consisting of an intramolecular hydroxyl group, a carboxylic acid group, a sulfonic acid group, a (meth) acrylic acid group, and an ester group.

The solvent allows the anionic resin to be smoothly applied to one surface of the base material 1.

The base layer 2 is formed on one surface of the base material 1 while the pretreatment composition is applied to the base material 1 and passed through the drying part 23. [ The base layer 2 arranges one surface of the substrate 1 so that the light-emitting layer 3 to be formed thereafter can be smoothly formed.

The base material 1 on which the base layer 2 is formed may be supplied directly to the light emitting layer forming portion 30 or may be wound and stored on a separate roller.

If the base material 1 on which the foundation layer 2 is formed is supplied between the first roller 31 and the second roller 32 in the light emitting layer formation step S20, 2). ≪ / RTI >

The light emitting composition may include a recursive composition that retroreflects light incident from the outside in the light emitting layer 3, a phosphorescent composition that absorbs light to store and emit light, or a mixture thereof.

The light-emitting layer includes a recursive layer formed of a recursive composition for retroreflecting light incident from the outside in the light-emitting layer; A phosphorescent layer formed of a phosphorescent composition that absorbs and stores and emits light in the light emitting layer; Or both the recursive layer and the phosphorescent layer.

When the light-emitting layer includes both the re-emission layer and the phosphorescent layer, it may be a sequence in which a recurrent layer is formed on the base layer and a phosphorescent layer is formed on the recursive layer, a phosphorescent layer is formed on the base layer, May be the order in which the recursive layer is formed.

The recursive layer may be formed of a recursive composition, wherein the recursive composition includes 100 parts by weight of a reflector, 150 to 260 parts by weight of a water-soluble polyacrylic resin, and 0.1 to 1.5 parts by weight of a thickener And they can be mixed and applied to the formation of a recurrent layer.

In the recursive composition, the reflector serves to retroreflect the light incident from the outside in the light emitting layer. Accordingly, it is desirable that the reflector has a high transparency along with a high refractive index so as to exhibit excellent retroreflective efficiency. For example, the reflector may be at least one reflector selected from the group consisting of glass beads and micro prisms.

Specifically, the reflector preferably has a refractive index of 1.9 or more, and more preferably has a refractive index of 1.9 to 2.2. When the refractive index of the reflector is within the above range, a focus is formed at the inner wall of the reflector to exhibit a high focus reflectance, and as a result, the retroreflectivity is high. However, when the refractive index is out of the above range and is less than 1.9, the focus reflectance is lowered, and as a result, the retroreflectivity is lowered.

It is also preferable that the reflector has a light transmittance of 98% or more. When the light transmittance is as described above, the light reflectance increases. However, when the light transmittance is less than 98%, the amount of absorbed light increases and the retroreflectivity may be lowered.

The refractive index and the light transmittance of the reflector are determined according to the composition, shape or particle size of the reflector, and the above properties also affect the adhesion of the reflector to the substrate and the durability of the reflector itself.

Accordingly, the glass bead satisfies the above-mentioned refractive index and light transmittance, and considering the adhesive force to the substrate and the durability of the glass bead itself, the glass bead preferably has a spherical shape, Lt; / RTI >

Also, the glass beads having an average particle diameter of 30 to 70 占 퐉 may be preferable because they exhibit an excellent refractive index, exhibit a low degree of desalination to the substrate, and exhibit excellent durability against external physical and chemical stimuli. If the average particle diameter of the glass beads is less than 30 占 퐉, the refractive index may be lowered. If the average particle diameter of the glass beads exceeds 70 占 퐉, the coating workability and adhesion to the substrate may decrease. The glass beads may also be a mixture of two or more kinds of glass wines having different average particle diameters within the above-mentioned average particle diameter range.

Normally, glass beads are made of an oxide of an alkali metal such as NaO, K ₂ O, an oxide of an alkaline earth metal such as MgO, CaO and the like, an aluminum oxide such as Al ₂ O ₃ , etc., in addition to a silica (Al ₂ O ₃ ) And an inorganic metal oxide component as a remaining amount. While the dual inorganic metal oxide component increases the durability of the glass beads, the transparency and the refractive index of the glass beads may be lowered when contained in a large amount because of inherent color. Accordingly, in order to ensure proper self-durability of the glass beads while satisfying the refractive index and transparency described above, it is preferable that the glass beads include the inorganic metal oxide component in an amount of 20 to 25% by weight based on the total weight of the glass beads have.

Micro-prisms have better light reflection efficiency than glass beads, but have low adhesion to substrates due to their unique shape. On the other hand, the glass bead has a lower light reflection efficiency than the microprism, but has a spherical shape and can exhibit more stable adhesion to the substrate than glass beads. Accordingly, glass beads or microprisms may be used alone or in combination as the reflector. In addition, when glass beads and micro prisms are mixed and used, it is possible to simultaneously improve the light reflection efficiency and the adhesive force by adjusting the mixing ratio.

Specifically, the micro-prisms are preferably used in an amount of 0.01 to 30 parts by weight based on 100 parts by weight of the glass beads. If the content of microprisms relative to the glass beads is too high, that is, if the micro-prism is more than 30 parts by weight with respect to 100 parts by weight of the glass beads, the content of micro-prisms desorbed from the light-emitting layer increases, There is a fear that the appearance of the reflective article may deteriorate. On the other hand, when the amount of microprism to be used for the glass bead is too small, specifically, when the micro-prism is less than 0.01 part by weight with respect to 100 parts by weight of the glass bead, the effect of improving the light reflection by micro-

The reflector may be a surface treated with a compound containing a silane group or an amino group for the purpose of increasing the refractive index, enhancing the durability, and improving the adhesion to the substrate. Specific examples thereof include silane compounds such as 3-aminopropyltriethoxysilane, aminoethylaminopropyltriethoxysilane, aminoethylaminopropyltrimethoxysilane, butanol-preaminoethylaminopropyltrimethoxysilane, and the like, or amine compounds Or the like, it may be preferable to increase the adhesive force to the substrate. At this time, the surface treatment method for the reflector can be carried out according to a conventional method.

The water-soluble polyacrylic resin preferably has transparency, excellent bonding force with a reflector, and excellent physical and chemical durability. The water-soluble polyacrylic resin has at least one anion selected from the group consisting of hydroxyl group, carboxylic acid group, sulfonic acid group, (meth) A water-soluble polyacrylic resin containing a functional group can be applied. The application of such a water-soluble polyacrylic resin containing an anionic functional group increases the adhesive force of the reflector to the substrate and increases the heat resistance of the light emitting layer, and is excellent in the dyeing and pattern formation during the transferring process at a high temperature Thereby enabling dyeing and pattern formation by the transfer efficiency.

More specifically, the water-soluble polyacrylic resin is a polyacrylic acid having at least one anionic functional group selected from the group consisting of a hydroxyl group, a carboxylic acid group, a sulfonic acid group, a (meth) acrylic acid group and an ester group in the molecule, , Polyhydroxyethylmethacrylic acid, and the like. In the above, the term "(meth) acrylic acid group" means a methacrylic group or an acrylic acid group.

The above-mentioned water-soluble polyacrylic resin can be used as an auxiliary component for promoting the above-mentioned effects, such as a polyurethane resin, an polyvinylalcohol resin, a polyvinylacetate resin Polyethylenoxide resin, polypropylene oxide resin, polyethylene glycol resin, polyacrylamide resin, ethyl cellulose resin, chitosan resin, chitin resin, chitosan resin, Is mixed with at least one water-soluble polymer selected from the group consisting of chitin, a polyamide-based resin, a polycarbonate-based resin, a silicon-containing polymer including polydimethylsiloxane (PDMS), and derivatives thereof , Wherein the content of the auxiliary polymer inhibits the effect of the present invention Does range may be appropriately selected within.

The water-soluble polyacrylic resin may be contained in an amount of 150 to 260 parts by weight based on 100 parts by weight of the reflector. When the content of the resin to the reflector is excessively low, specifically less than 150 parts by weight, the adhesive force of the reflector to the substrate is lowered and the effect of improving the heat resistance of the light emitting layer is insignificant, May occur. On the other hand, when the content of the resin to the reflector is excessively high, specifically, when it exceeds 260 parts by weight, the refractive index may decrease due to the relatively low reflector content.

The water-soluble polyacrylic resin is applied in an amount of 220 to 250 parts by weight based on 100 parts by weight of the reflector, so that the adhesion between the base and the reflector and the reflection effect of the light-emitting layer can be improved at the same time.

In the recursive composition, the thickener improves the coating property to the substrate by controlling the viscosity characteristics of the recursive composition, and improves the dispersibility of the reflector in the formed light emitting layer and the uniformity of the light emitting layer thickness.

Examples of the thickening agent include cellulose type thickening agents such as hydroxypropylmethyl cellulose (HPMC), hydroxyethylmethyl cellulose (HEMC), ethylhydroxyethyl cellulose (EHEC) and carboxymethyl cellulose cellulose (CMC), and the like. These may be used singly or in combination of two or more.

The thickener may be included in an amount of 0.1 to 1.5 parts by weight based on 100 parts by weight of the reflector. When the content of the thickener for the reflector is too low, specifically less than 0.1 part by weight, the recursive composition becomes high in viscosity, and the coating process is not easy and the processability in forming the light emitting layer is lowered, On the other hand, when the content of the thickener for the reflector is excessively high, specifically, when the content of the thickener exceeds 1.5 parts by weight, the flowability of the recycled composition is excessively increased and the processability is deteriorated. From the viewpoint of improvement, it is more preferable that the thickener is contained in an amount of 0.1 to 1.5 parts by weight based on 100 parts by weight of the reflector.

The thickener may be applied in an amount of 0.9 to 1.3 parts by weight based on 100 parts by weight of the reflector. In this case, the refractory composition may have excellent workability and flowability suitable for forming a coating layer having an appropriate thickness on a substrate.

The phosphorescent layer absorbing and storing light and emitting and emitting light in the emissive layer may be formed of a phosphorescent composition. The phosphorescent composition may include 100 parts by weight of a phosphorescent pigment, 150 to 260 parts by weight of a water-soluble polyacrylic resin, and 0.1 to 1.5 parts by weight of a thickener And they can be mixed to form a light emitting layer including a phosphorescent layer.

The phosphorescent pigment absorbs and scales light energy and then emits the accumulated energy in the form of fluorescence or phosphorescence in a dark place to emit light. Specifically, the phosphorescent pigment may include any one compound selected from the group consisting of pyridine-based, quinazoline-based, bisquinazoline-based, and combinations thereof, and specifically includes MO.SiO ₂ , Al ₂ O ₃ : Eu, MO.Al ₂ O _3: Eu, ZnS: Cu, ZnS: Cu, Cl and combinations thereof, but may be any one selected from the group consisting of, but is not limited to such.

The phosphorescent pigment has an afterglow luminance could be more than 1.5cd / m ^2, may be less than 2.3 cd / m ^2. The phosphorescent pigment may have a specific gravity of less than 4.5 and a specific gravity of 4.1 or less. The phosphorescent pigment may have been subjected to a water-resistant surface treatment. The application of the water-resistant surface-treated phosphorescent pigment can protect the weak phosphorescent pigment in water and alleviate the luminance drop phenomenon occurring when mixing with other components. The water-resistant surface treatment of the phosphorescent pigment may be a coating of an inorganic particle composed of alumina, silica, mica, or a combination thereof on the particle surface of the phosphorescent pigment, or may be coated by chemical treatment.

The microcapsules of the phosphorescent pigment may have a particle size of 45um or less, 0.01 to 23um, or 0.1 to 12um or less. When the microcapsules having the above-mentioned particle size are applied, the modification of the phosphorescent pigment can be reduced and the miscibility in the solvent can be improved.

The water-soluble polyacrylic resin preferably has transparency and excellent bonding strength with a phosphorescent pigment and is excellent in physico-chemical durability. The water-soluble polyacrylic resin is preferably at least one selected from the group consisting of hydroxyl groups, carboxylic acid groups, sulfonic acid groups, (meth) A water-soluble polyacrylic resin containing an anionic functional group can be applied. The application of the water-soluble polyacrylic resin containing such anionic functional group increases the adhesion of the phosphorescent pigment to the substrate and increases the chemical resistance of the phosphorescent pigment to maintain excellent phosphorescent effect even when mixed with an aqueous solvent, Formation can reduce damage in this process.

More specifically, the water-soluble polyacrylic resin is a polyacrylic acid having at least one anionic functional group selected from the group consisting of a hydroxyl group, a carboxylic acid group, a sulfonic acid group, a (meth) acrylic acid group and an ester group in the molecule, , Polyhydroxyethylmethacrylic acid, and the like. In the above, the term "(meth) acrylic acid group" means a methacrylic group or an acrylic acid group.

The above-mentioned water-soluble polyacrylic resin can be used as an auxiliary component for promoting the above-mentioned effects, such as a polyurethane resin, an polyvinylalcohol resin, a polyvinylacetate resin Polyethylenoxide resin, polypropylene oxide resin, polyethylene glycol resin, polyacrylamide resin, ethyl cellulose resin, chitosan resin, chitin resin, chitosan resin, Is mixed with at least one water-soluble polymer selected from the group consisting of chitin, a polyamide-based resin, a polycarbonate-based resin, a silicon-containing polymer including polydimethylsiloxane (PDMS), and derivatives thereof , Wherein the content of the auxiliary polymer inhibits the effect of the present invention Does range may be appropriately selected within.

The water-soluble polyacrylic resin may be contained in an amount of 150 to 260 parts by weight based on 100 parts by weight of the phosphorescent pigment. If the content of the resin to the phosphorescent pigment is excessively low, specifically less than 150 parts by weight, the adhesive strength of the phosphorescent pigment to the substrate may deteriorate and the phosphorescent pigment may be damaged. On the other hand, when the content of the polymer to the phosphorescent pigment is excessively high, specifically, when it exceeds 260 parts by weight, there is a possibility that the phosphorescence effect is not sufficiently exerted due to the relatively low phosphorescent pigment content.

The water-soluble polyacrylic resin is preferably applied in an amount of 200 to 240 parts by weight based on 100 parts by weight of the phosphorescent pigment, because adhesion and luminous efficiency of the base and the phosphorescent pigment can be improved at the same time.

The thickening agent in the phosphorescent composition controls the viscosity property of the phosphorescent composition to increase the coating property to the substrate and to improve the dispersibility and uniformity of the phosphorescent pigment in the formed phosphorescent layer. Examples of the thickening agent include cellulose type thickening agents such as hydroxypropylmethyl cellulose (HPMC), hydroxyethylmethyl cellulose (HEMC), ethylhydroxyethyl cellulose (EHEC) and carboxymethyl cellulose cellulose (CMC), and the like. These may be used singly or in combination of two or more. The thickener may be applied in an amount of 0.1 to 1.5 parts by weight based on 100 parts by weight of the thickening pigment, and 0.9 to 1.3 parts by weight.

The recycled composition or the phosphorescent composition forming the light emitting layer may further contain an additive as required and may contain a dispersant, a curing agent, an ultraviolet absorber (e.g., a triazine-based ultraviolet absorber, a benzotriazole-based ultraviolet absorber, etc.) (For example, calcium carbonate, calcium phosphite and the like), a surfactant, an antistatic agent, or a precipitation preventing agent for glass beads, Alone or in admixture of two or more.

Examples of the dispersing agent include, but are not limited to, tricalcium phosphate, trisodium phosphate, magnesium phosphate, magnesium pyrophosphate, and the like. Commercially available dispersants may also be used. Specific examples thereof include BYK-JET (TM) 9170 (manufactured by BYK).

Also among the above dispersing agents, wetting and dispersing agents may be preferred.

The dispersing agent may be included in an amount of 0.1 to 10 parts by weight based on 100 parts by weight of the reflector or the phosphorescent pigment. If the content of the dispersant in the reflector is too low, the effect of adding the dispersant is insufficient. On the other hand, if the content of the dispersant in the reflector is too high, the dispersant remaining in the final prepared light emitting layer acts as an impurity, It is not desirable because of concern.

As the curing agent, various curing agents having an isocyanate group, an epoxy group and an aziridine group may be used depending on the kind of the polymer. These reactive groups react with the hydroxyl group, amino group, carboxyl group and the like contained in the polymer to cure into a crosslinked structure. Accordingly, when a polyacrylic resin is used as the polymer, it is preferable that an isocyanate free from yellowing is used as a curing agent.

As the surfactant, an anionic surfactant, a nonionic surfactant, a high-molecular surfactant, etc. may be used alone or in combination of one or more. Examples of the anionic surfactant include formalin condensates of naphthalenesulfonic acid salts, ligninsulfonic acid salts, formalin condensates of special aromatic sulfonic acid salts (formalin condensates of sodium alkylnaphthalenesulfonate and sodium naphthalenesulfonate such as butylnaphthalene, sodium cresylsulfonate and 2-naphthol -6-sodium sulfonate, formalin condensate of sodium cresyl sulfonate, etc.), polyoxyethylene alkyl ether sulfate, and the like. Examples of the nonionic surfactant include polyoxyethylene sorbitan fatty acid esters, polyoxyethylene alkyl ethers, polyoxyethylene alkyl phenyl ethers, polyoxyethylene acetylene glycols, polyoxyethylene derivatives, and oxyethyleneoxypropylene block copolymers. have

Examples of the polymeric surfactant include polyacrylic acid partial alkyl ester, polyalkylene polyamine, polyacrylic acid salt, styrene-acrylic acid copolymer, vinylnaphthalene-maleic acid copolymer and the like.

As described above, the water-soluble polyacrylic resin can stably adhere the reflector or the phosphorescent pigment on the substrate with high adhesive force and can increase the washing fastness of the fiber or fabric. Further, the water-soluble anionic polymer can be used in a printing process for subsequent dyeing and pattern formation, in particular, in an output printing process, particularly in a sublimation process at a high temperature, by increasing the glass transition temperature of the light emitting layer, It is possible to prevent discoloration and combustion of the base material during the transferring process and to improve the feel or touch of the fiber or fabric including the light emitting layer formed using the recycled composition.

Also, since the recycled composition or the phosphorescent composition contains a thickening agent together with the above-mentioned water-soluble anionic polymer, it can exhibit a light reflection or luminescent effect excellent in the thickness of the light emitting layer which is significantly thinner than the conventional one, The present invention is particularly useful for forming a light emitting layer in various articles such as fibers, fabrics and fabrics.

The recursive composition may have an appropriate viscosity, and the recursive composition may have a viscosity of 4200 to 4800 cps by adjusting the amount of the solvent.

Thus, the first roller 31 may be provided with a recycled composition or a phosphorescent composition. For example, a recursive composition may be applied to the base layer 2 via a first roller 31 with a recycled composition applied thereon and passed through a drying section 33 to form a recurrent layer that reflects light.

Then, the luminous composition is applied onto the recycled layer by passing the base material 1 on which the recursive layer is formed through the first roller 31 with the luminous composition, and the luminous layer is passed through the drying section 33 to emit light and emit light on the recurrent layer .

The order of application of the recursive composition, the phosphorescent composition, may vary depending on the use of the fabric. In addition, only the recursive composition and the phosphorescent composition may be formed on the base layer 2.

On the other hand, since the base material 1 on which the base layer 2 is formed passes between the first roller 31 and the second roller 32 together with the base material 50, the light emitting composition (recycled composition or light emitting composition) Do not touch the roller (32). Accordingly, it is possible to prevent the conventional problems caused by the deposition of the light-emitting composition on the second roller 32, so that the light-emitting layer 3 can be accurately and precisely formed on the base layer 2.

The base material 1 on which the light emitting layer 3 is formed may be supplied directly to the post-treatment section 40 or wrapped on a separate roller.

The substrate 1 on which the light emitting layer 3 is formed is supplied between the first roller 41 and the second roller 42 in the protective layer forming step S40. The post-treatment composition adhering to the first roller 41 may be applied on the light-emitting layer 3. The protective layer 4 is formed on the light emitting layer 3 while the post-treatment composition is applied to the light emitting layer 3 while passing through the drying portion 43. The protective layer 4 protects the light emitting layer 3 from external requirements and prevents the light emitting layer 3 from being damaged.

The protective composition comprises 100 parts by weight of a solvent and 3 to 8 parts by weight of a water-soluble polyacrylic resin. In this case, the solvent is preferably a polar solvent, and any solvent selected from the group consisting of water, an alcohol having 1 to 5 carbon atoms, and a mixture thereof may be used.

The water-soluble polyacrylic resin includes an anionic functional group selected from the group consisting of a hydroxyl group, a carboxylic acid group, a sulfonic acid group, a (meth) acrylic acid group and an ester group in a molecule.

A transfer layer (not shown) is formed on the light-emitting layer 3 or the protective layer 4 in the transfer layer forming step S40. The transfer layer shows pattern or color.

A detailed description of the transfer layer forming step (S40) can be applied to a known method of forming a print layer on a light emitting layer of a reflective fabric and a manufacturing method thereof (Patent Registration No. 10-1322371) filed by the present applicant, A detailed description will be omitted.

The luminescent material fabricated as described above can be applied to various articles requiring visibility or design due to the light reflecting effect of the light emitting layer due to excellent physical properties of the base layer 2, the light emitting layer 3, the protective layer 4, Specifically, it can be applied to a display panel, a semi-use fiber, a safety garment, a garment, a baby article, a fabric for night work, and the like.

The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.
