Description of the invention: [Technical field to which the invention pertains] The beauty body body, in particular, relates to an optical modulation body which can be incident on its first line _ into the sinusoidal factor (4) in the silk. [Priority technology] The variable system includes the inclusion of the "" continuous base® _ inclusion body, which controls the properties of the inclusion body in the related art to make the optical modulation body have Ο _ permeability. The inclusion body characteristics may include the inclusion body. Optical modulation, the relative wavelength of the inside, the form and arrangement of the inclusions, the positive scale of the inclusion, the stalk and the scorpion include most inorganic strip chains, including the -15 objects arranged in the package m Matrix _ optical absorption is missing. The film has a light absorbing light which is transmitted along a film ΐ which is arranged in parallel with the strip iodine chain and then transmitted in the direction of the vertical strip. Iodine ^ two sizes, and its wavelength], at the wavelength of visible light, and has a large amount of light = if this optical characteristic of the optical modulation body usually looks like a diffusion transmission of a S-sense modulation (diffuse transmission) Or from the light and the different inorganic inclusions, 'may provide a different one - the example is attached to the polymer film, where the mica thin segment has two or more than L and then coated Load and then give the metal glass. By controlling the Si _ plane, it is possible to provide a strong directional root effect for reflection. 'It is possible to make a security screen'. When viewed from a specific perspective, the image is highly reflective, while from a different perspective. Watching Τ 'is transparency. In addition, a large-sized thin segment is coated in the film, and the 200944866 / «, the thin segment can also provide reflection when it has a color development (ie, selective positive reflection) according to the state of the incident light. Interference/collision signs. In such applications, all thin segments within the film must be oriented relative to one another. - However, there are several disadvantages to the use of optical films made with polymers filled with inorganic inclusions. Generally, the adhesion between the inorganic particles and the polymer matrix is poor. ‘This, when the optical modulation body is subjected to stress or deformation perpendicular to the substrate, its optical properties are deteriorated. This will damage the coupling between the substrate and the package, and will also break the rigid I package. Furthermore, in order to orient the inorganic inclusions, the g step must be further considered, thus making the manufacturing process more complicated. "However, the most important thing is that because the matrix constituting the conventional optical modulation body and the inclusion body coated in the matrix have optical properties of optical isotropic properties, thus the optical modulation is reduced.

Isotropic" - the word indicates that when the light passes through the object, the refractive index of the object is fixed 'independent of its direction. The term "2 heterosexuality" means that the optical properties of an object differ depending on the direction of the light. Anisotropic objects have birefringence and are opposite to isotropic. Go: 3Ϊ Ϊ J means: the illuminating light is reflected, refracted, scattered; or the intensity, fluctuation period or characteristic of the first line has changed. [Comparative to the efficacy of the prior art] According to the hairline of the hairline, if the polymer is disposed in the respective fibers, and the light is irradiated on the substrate, the isotropic substrate/these The optical implants of birefringent polymers are different, so a 200944866,-birefringent interface is formed between the two. Therefore, by changing the light of the Wei-ray to integrate, scatter, reflect, or refract light, it can be used only when the brightness-enhanced film is used as a brightness-enhancing film, and the brightness is different. Therefore, the optical modulation of the present invention has an excellent 9-degree enhancement effect without the lion becoming a majority layer. In addition, since there are not hundreds of layers stacked by =, it is very convenient to manufacture and can be greatly changed.

Substrate 1 〇〇 and birefringent polymer 11 〇 can use only one kind of raw fat sealing. At the same time, the method of changing the isotropic material into a birefringent material ^ is generally known, for example, if oriented under the temperature condition τ, poly & The molecules can be oriented and their materials become birefringent. These birefringent polymers can be arranged in the same direction in the substrate and stretched in the same direction.. The second figure is an optical of another embodiment of the invention. A partial cross-sectional view of the modulation body, in which a plurality of birefringent polymers 21 are disposed on the substrate in the same direction, and the double-dano polymer 210 can be vertically-light source disposed in the substrate. When 'can turn a large optical modulation efficiency', if it is a shot, a coherent double-folding compound (10) Dispersing another configuration fish 'and intervening birefringent polymer 210 may be in contact with each other or spaced from each other. If the inter-sized birefringent polymer 21G is in contact with each other, the birefringent poly-210 may be divided into a plurality of layers. Lin (4) mouth (4) in the case of the case of 't. If three or more diameters are different and the refractory is refracted, the perpendicular refracting polymer will be cut in the longitudinal direction. The triangle resulting from the interconnection of three adjacent circular centers will be an equilateral triangle. Further, from the vertical alignment of the birefringent polymers (the cross section of the cylindrical body), the arrangement of the cylinders shows that the circular circles in the first layer and the circular systems in the second layer are in contact with each other. The circular shape in the second layer and the circular system in the third layer are in contact with each other, and the layers (10) below the third layer are in circular contact with each other: = and, with respect to such birefringent polymers, due to the respective birefringence The polymer is in contact with each other on the side faces of the cylindrical body, so that only one condition is required: "Each each & refractive polymer and two or three birefringent polymers are in contact with each other on the side faces of the cylindrical body thereof". For example, in this range, the structure may also be that the circle in the first layer and the circle in the second layer are in contact with each other, and the circle in the second layer and the circle in the third layer are used between the second layer and the third layer. The supporting media are spaced apart from each other, and the circles in the third layer and the circles in the fourth layer are in contact with each other.

The refractive polymer is refracted with respect to each optical modifier of 1 (10) 3 . Compared with the volume ratio of ΐΐί f _. If the volume ratio of the birefringent polymer is ί i to the light, the effect is very small. If the body of the birefringent polymer is sprayed with filaments, the birefringent polymer is produced. The diameter of the refractive poly- anisotropic core fiber is less than === so that the optical dimension is rarely reduced, and the light will be slightly diffused on the surface of the polymer. The cross-sectional diameter of the heterogeneous yarn core fiber can be changed according to the standard of the optical object. The green color of the optical object is _, and for the reflection, _, or transmission, there are i lines, infrared rays, and microwaves, which require most different diameters of light, Preferably, the good optical modulation body may include a structural surface layer according to its purpose. The third figure to π is a structural surface of the optical modulation body of the re-embodiment of the invention = a surface view. As shown in the third figure, the optical The incident surface and the emission table of the modulation body can be illuminated from 12 200944866 light source 300a The light rays are parallel. In this case, as shown in the fourth figure, the birefringent polymer 321b and the birefringent polymer 320b may be intermittently arranged. wherein the birefringent polymer 321b is located adjacent to a light source 3〇〇b Above and in close configuration, the position of the birefringent polymer 32〇b is away from the light source 3, and the surface layer of the structure can be formed on the surface of the light. The surface layer of the structure can be a cylindrical, biconvex or convex lens. More specifically, as shown in the fifth figure, the light exit surface of an optical modulator may be a convex lens shaped arcuate surface 330c. The curved surface 330c may focus or disperse light transmitted through the surface. In addition, as shown in the sixth figure, the light exiting surface may form a prismatic state 33〇d. In this case, the birefringent polymer 320d' may not be disposed in the structural surface layer 330d as shown in the sixth figure. As shown in the seventh figure, the birefringent polymer 32〇e can be disposed in both the substrate and a surface layer k. Alternatively, as indicated by the eighth circle, the birefringent polymer 320f may be disposed only within the structural surface layer 33〇f. By the Matt treatment, a large number of irregularities can be formed on at least one surface of an optical modulation body, and scratch resistance can be produced. More preferably, the matte finish may be applied to the other surface of the structure surface if it adversely affects the utility of the present invention. At the same time, the light of the transmission source may include natural light and polarized light, and a birefringent material may be used as the birefringent polymer. However, the birefringent polymer is preferably solid from the viewpoint of the orientation of the cross-sectional shape or stability, durability, and the like. Therefore, in the first embodiment of the present invention, the birefringent polymer is disposed in an isotropic substrate to achieve effective light modulation through the double faces between the substrate and the birefringent polymer. 1 In the second embodiment of the invention, the birefringent polymer is preferably a double-fold. More preferably, the birefringent fiber preferably comprises an anisotropic yarn core dimension and is miscellaneous. More preferably, the optical conditioning material comprises anisotropic core fibers disposed in the respective fillers. In the technical spirit disclosed in the first embodiment of the present invention, a plurality of birefringent polymers are disposed in a plurality of materials, and the light is adjusted according to a birefringent interface between the same-substrate substrate and the birefringent polymer according to a desired purpose. change. However, with 13 200944866 ΐΐί, the silk fabric of the (four) compound is included in the filler, and the directionality of the optical fiber can be turned over. Frequency-silver effect is as good as light wind and substrate _ optical modulation _ (also known as the present material - implementation "). Therefore, the optical modulation efficiency can be remarkably improved. Ξ本发_狮, can take the ride of the optical materials of the New Zealand, and preferably the first embodiment of the material that has been explained Ϊί ί core fiber can be described in the birefringent polymer ^ all f Material: Thus, for example, an anisotropic polynaphthalene dicarboxylic acid can be used as the core fiber, and an isotropic naphthalene monoterpene ethyl ester (C0-PEN) can be used as the filler. V 7 is the same as the "1' of the female filler and the anisotropic core fiber in the space of the X, the set of shouting mismatch, for the dispersion of each pair. Usually, (iv) the change in ability two == square ratio. Therefore, when the refractive index is in a certain specific axis ϊ ί ί ί ί ί ί ί ί ί ί ί 顾 顾 杂 杂 杂 杂 杂 杂 杂 杂 杂 杂. On the contrary, the refractive index of the temporary force-last surname is approximately the same as the refractive index of an anisotropic or birefringent-specific I, regardless of how the birefringence of the birefringent material is parallel to the axial electrical The polarization of the site can be passed through - fiber. In addition, if the refractive index of the isotropic filler or the birefringent material is in a particular axial direction, the light will not substantially scatter and will pass through an object. According to the refractive index of the hair filler and the anisotropic core fiber, when the relative two axes are different, the difference is preferably 〇.03 or lower than 0.03, and the third axis is adjusted to be 05 or higher than G. At G5, the highest light can be obtained (9). Suppose, assuming that the refractive index of a substrate in the X-axis is ruling, the refractive index is 1 and the refractive index is 1 in the 2 axial direction, and A birefringent pre-modulated fiber has a refractive index of nX2 in the X-axis, a fold in the y-axis of 200944866, an incident rate of ηΥ2', and a refractive index of 2 in the axial direction; then three refractions in the axial direction of the crucible In the rate, it is best to have at least two refractive indices in the X, y, and ζ axial directions of the tunable fiber:: shot $ The birefringent optically modulated fiber is only transmitted by > VL red from 4 Π right η Υ 2 = η Ζ 2 When it is beneficial to increase the optical modulation efficiency: the line is the same as the vibration of the 2nd gas t-material at the same time: the vibration is different. The convulsion is different. 射 The material and the birefringence __ interface are also fine. In the double-refractive fiber.. 隹 = anisotropic yarn to turn the opposite interface. Preferably, the a s i birefringent fresh tunable fiber may comprise yarns arranged in the lap; It is assumed that the refractive index of the isotropic core fiber in the x-axis is nY2, and the refractive index in the z-axis is H ΐ ΧΙ ΧΙ ^^^_ηΧ3 'the refractive index in the y-axis is nZ3, then The refractive indices η χ 2 and ΠΧ 3 2 can be either higher or higher than G.G5. In this case, the absolute value of the difference between the folds 9:HnZ3 may be lower than 〇.03. More preferably, the variable fiber system is stretched along the x-axis, and when the refractive index nX2 and ηΧ3 ηΥ^ΡΙ are perpendicular to 〇. 1 or higher than 0.1, and the refractive indices ηΥ2 and =3 = and the refractive indices ηΖ2 and ηΖ3 The difference in absolute value is lower than the 〇 shoulder Ϊ ' ΐΐϊ increases optical modulation efficiency. At the same time, it is advantageous if the optically modulated fiber has a large difference in refractive index along the axis of J ′, and the difference in refractive index between the other two axes is small and preferably the same. Between the refracting fibers of the yarns and the anisotropic palladium in the birefringent fibers: both ΐί and the filler can form a birefringent interface. This is a case where the birefringence interface is formed between the earth material and the birefringent fiber, and the optical modulation efficiency is remarkably increased. ^ The woven fabric core fiber may preferably comprise a fiber outer cover, like a coated fiber core body. The optical modulating body preferably comprises a plurality of freshly tunable fiber bundles having different cross sections, and the filler and the At least one of the anisotropic core fibers may be composed of a birefringent polymer material such as a birefringent cholesteric material. Further, at least the drop-adjusted fiber and the anisotropic core fiber are preferably stretched in a longitudinal direction. According to a preferred embodiment of the optically clear fiber, it can be a composite. In this case, the core of the core-sheath composite fiber corresponds to the anisotropic yarn, and the saddle portion corresponds to the filler. </ RTI> <RTIgt; </ RTI> <RTIgt; </ RTI> </ RTI> <RTIgt; In the ninth figure, the core corresponds to each direction = ^ fiber' and the portion 400a corresponds to the filler.

Starting from the concentric part, the number of 匕 refractive interfaces can significantly increase the optical modulation effect with anisotropic core fibers and fillers.

Furthermore, if there are 10 stars in the form of a star-shaped yarn, the composite yarn _ will have a birefringence L and can produce (10) or more optical modulation. According to the star of the present invention, the yarn can be produced by the conjugate ((9) extrusiQn) method, but is not limited to J. In the typical star-shaped yarn, the star is left after elution (eluting) = The part is an ultrafine yarn, and whether or not it is birefringent; however, the day of the invention, the sky of the star-shaped yarn is not dissolved, and the star-shaped yarn having different optical characteristics is obtained. The cross section of the star-shaped yarn in the longitudinal direction may be any shape, according to its purpose. The star-shaped yarn may also have a circular or non-circular cross section, such as a shape, a polygon, and a non-circularity in which the non-circularity is in the range of 〇 to (10). Similarly, the star-shaped portion of the star-shaped yarn may have any longitudinal section and may have a s non-circular cross section, such as an elliptical shape, a polygonal shape, and a non-circular non-circular shape of 100. 11 to 20 are birefringent optical and variable fiber cross-sections according to another embodiment of the present invention. From the twentieth figure of the busy brewing: "The shape, size, number and arrangement of the stars can be effectively controlled according to optical modulation. Figure 12 is a cross-sectional view of a typical star-shaped yarn. ^ 17 200944866, most of the approximately circular star portions 520a are separated by a day 51〇a. Thirteenth figure = Sky-shaped yarn profile _ shows that the area of the 51Gb of the sky is larger than the surface of the star part 52〇b. The day tt yarn is finely marked and has a turning surface. The star portion 52〇d in the fifteenth figure has an elliptical cross section and is curved. In addition, the cross section of the star-shaped yarn in this figure is a rectangular structure or a non-circular cross section. A blood six-circle and a seventeenth figure, the star may be located in the center of the star-shaped yarn, or the sky may not be located in the center of the star-shaped yarn. ❹ In some embodiments, the size of the stars may vary. For example, as shown in Fig. 19, the star-shaped yarn may be a star of a different size. In this particular embodiment, the cross-section of the 52Gg portion of the star-shaped portion may be opposite to the other surface of the star-shaped portion 521g. The size of the two parts of the genre can be - substantially different sizes. Further, as shown in the twentieth diagram, the star portion 1 may be provided with a birefringent and/or isotropic sheath portion 53A. , as previously described, the light passes through the birefringent star-shaped yarn % in a substrate to produce optical modulation at a birefringent interface. More specifically, the twenty-second cross-sectional view shows that when light is incident on the birefringent star-shaped yarn of the present invention, p & (solid line) passes through the birefringent star-shaped yarn, which is unfaced. The pure 'that is' is the interface between the refracting star-shaped yarn and the interface between the star-shaped turn and the day touch, which does not affect the chopping and = loss. However, 疋S > skin (dotted line) Ij produces optical 1 ' under the influence of the birefringent interface, that is, the boundary and/or birefringence recorded by the substrate lion's celestial yarn = between the star and the sky The boundary line affects the s-wave portion of the S-wave via optical modulation, such as reflection, scattering, or refraction, and the S-wave returned by H becomes S-wave or p-wave after reflection, and therefore, if the double-day recording is used, For example, if you use the eight-type birefringent fiber, you can have excellent brightness enhancement efficiency. Double = shooting the yarn can also include silk and no. Therefore, when the double-refractive interface is used, there is a significant optical modulation efficiency compared to the case where no birefringence is formed in the star-shaped yarn. 200944866 1 It is better to be able to configure most stars in the star-shaped yarn, and the heavens and the courts? ? The best is 2:8 to 8:2. When there is eight o'clock in the -star-shaped yarn, it is advantageous to produce the maximum optical modulation effect. The star shape is preferably G·3 to 2G denier, and the optical modulation body is equal to the centimeter (cm3) of 500 s 4, 〇〇〇, _ 天, the refractive index of the sky is better. The optically modulated substrate has the same refraction. The picture and the twenty-third figure show that the star-shaped yarn can be woven by using ϊ, ί Π b and warp _, hidden. The weft and _ ίί ΐ can be a star-shaped yarn and the other weft or warp can be a homogenous fiber. Preferably, the weft or the warp may use from 1 to 200 star-shaped yarns. According to still another embodiment of the optically modulated fiber, the birefringent fiber may be a retanning line comprising an isotropic filling portion and a majority An anisotropic composite portion partially filled with isotropic filling. Preferably, the isotropic filling portion is a plurality of, and the plurality of isotropic filling portions are preferably in the composite yarn _ parallel or intersecting, and the composite rotating cross section may be a non-circular cross section 'such as non The ellipse with a roundness of (10) and a fan shape. In particular, the twenty-fourth to twenty-eighthth drawings are cross-sectional views of a birefringent optically modulated fiber according to an embodiment of the present invention.

In the twenty-fifth figure, an isotropic filling portion 7〇〇b divides the two-yarn yarn into two anisotropic composite portions 71〇b in the lateral direction. The isotropic filling portion 700c formed in the twenty-sixth drawing has a "+" shape. The isotropic filling portion 7〇〇d formed in the twenty-seventh figure has a "γ" shape. The twenty-eighth figure shows that most of the isotropic filling portions 700e can be formed longitudinally. In this case, the plurality of isotropic fillers 700e may be parallel or non-parallel to each other. X According to a second embodiment of the present invention, the optically modulated spun-forming of the birefringent polymer may be extended in one direction, arranged into a woven or woven bundle, and then impregnated into a material and fixed to the substrate. The spinning and stretching of the optically modulated fiber, or the weaving process of the fabric & 200944866, 'bundle, can be carried out using a conventional method, but is not particularly limited. When the fabric or woven fabric is wetted and fixed to the substrate, different methods can be used, for example: immersing the non-woven fabric in the monomer and/or oligomer solution, that is, immersing the substrate in the precursor (Precursor) and then using Light and/or thermal polymerization of a precursor of a supporting medium; or, immersing the fabric or woven fabric in a polymer solution of a supporting medium, and then removing the solvent; or, preparing a fine powdery supporting medium, impregnating the fine powder into the fabric Or weaving, then hot melt. Further, according to another method, the present invention can be realized by a melt extrusion method. More specifically, when the birefringent polymer dispersed and aligned in the substrate has a cross section perpendicular to the longitudinal axis, a type of one can be used. Profile raeth〇d 'Separate the discharge port of an extruder into several spun yarns = where 'every-spindle head is extruded in a polygon to form a birefringent polymer shake/曰' The February crucible constituting the substrate was extruded from the spinneret between the two spaced apart spinnerets. If a birefringent copolymer dispersed and aligned in a supporting medium has a vertical long axis ί if the surface is substantially circular, ' another type of squeezing method can be used to squeeze a plurality of spinnerets and cross-section The continuous spinneret = the pressure (10) of the bismuth (four) compound blush, and then the sputum is used as the resin of the substrate. In these cases, a heat-dissipating resin of a different type, such as a filament, a filament, or a different type, is extruded in a specific form from the spinneret f of the upper portion of the machine. Thus, the above-described dispersed spur structure is formed. When the anisotropic yarn core fiber is disposed as a birefringent fiber in the isotropic filler, as shown in the twenty-ninth figure, the optical modulation effect of the modulation body can be remarkably ", and the in-line configurable _ 'Stars composite yarn, and to touch the glory yarn to form a well and ridicule &拄;, 'form interlaced most composite yarn, and placed in one or two: Γ extremely excellent The optical modulation effect is superior to that of the acid-reducing fiber. 20 200944866 [Mode of the Invention] The present invention will be described in detail in conjunction with a number of examples and experimental examples. In view of the present invention, the present invention is not limited to the following examples and experimental examples. [Example 1] Polyethylene naphthalate (10) having a viscosity of IV〇.53 is polymerized and then When the original yarn of the undrawn yarn 150/24 is spun, the temperature of the spinning yarn of the metric/minute (M/min) is twisted into three times, and the undrawn yarn is twisted three times. ^ Produce a 50/24 drawn yarn.

On the sheet, wherein the surface of the pC alloy sheet is met-processed, and then laminated with a specific tension, wherein the pc alloy sheet has a refractive index of L 57. Thereafter, Epoxy acrylated vinegar (_y ❹ ^Τ,,) is mixed with urethane acrylate to form an external photohardenable coating resin (refractive index is i. (4) coated on a pc alloy sheet. A plurality of fibers are stacked in the PC alloy sheet, and the wheel i is introduced at a certain point thereon to receive the secondary and secondary ultraviolet light hardening, thereby producing a mixed sheet having the double-twisted fiber bundle. The coating is intended to exhibit a refractive index of 1.54 before hardening of the UV coating, but after curing, the refractive index is 1.5 J: the thickness can be made. 4 μm of a sheet-like optical modulation body. [Example 2] A sheet-like optically modulated body was produced in the same manner as in Example 1, except that a birefringent composite fiber was used instead of the typical birefringent stretched p-fiber. More specifically, it is said that in the core-sheath composite fiber used, the core of the core sheath yarn is ρΕΝ (ηχ = 1.88, ny = 1.57, ηζ = 1.57), and the sheath portion is C0_PEN (ηχ 21 200944866 = h 57, ny = 1 π, , , and the stretching process does not change the refractive index of f = even if the yarn 150/24, Ht is spun yarn 'to obtain unstretched 50/^. ..., and then stretched three times, thereby obtaining a drawn yarn [Example 3] using the same method - sheet-like optical observation, but making the star-shaped yarn i, the typical birefringence stretching fiber. In the ^ star-shaped H system used, an anisotropic PEN is used (ηχ = 1.88, ny = ❹ isotropic two Ev (nx for ~ Xingguang and corpse (10) stars are arranged in the various fillers.

[Example 6] In order to simplify the knit woven shaft of the fiber used in the sheet of Example 4, the side strands were woven into The weft density of 5 inches per inch. In the formula, the left side of each strand is reduced to fox, and the remaining is 762 im. The grading method is applied to the weave method, so that the fabric with the minimum weft density is released from the material. At the same time, the female was stacked in the same manner as in Example 1 and coated with a coating agent to be hardened, thereby producing a sheet-like optically modulated body.
